CC: F200 AB: Random amplified polymorphic DNA (RAPD) analysis was used to characterize barley germplasm genetic diversity. For the analysis 303 morphologically distinctive accessions were selected from the VIR germplasm collection, St. Petersburg, Russia and the MAFF Genebank, Tsukuba, Japan to represent the principal regions of barley cultivation. A total of 93 polymorphic bands scored from RAPD patterns were used to generate a genetic distance matrix, which was used in both cluster and principal coordinate analysis. Both analysis clearly separated barley cultivars and local populations into three distinctive groups, which evidently reflect different directions in evolution and geographical distribution of barley. The hierarchy of accessions clustering in the first group indicates the westward distribution of barley from West Asia to Europe and New World across Ethiopia and then Mediterranean region. The principal breeding trends based on spike morphology are also observed in this group. The second group is associated with eastward distribution of the crop and represents a unified genetic group, which consists of East Asian and Central Asian accessions. The third distinctive group identified is connected with the evolution and dissemination of hulless forms in Central Asia and the Caucasus region. The conformity of identified genetic groups and clusters with the global centers of crops diversity (gene centers) determined by Vavilov (1926) and modern ecogeographical classification of barley is discussed.

CC: F200 AB: The following comparisons between crops and their closely related wild relatives provide clues for discriminating between monophyletic and polyphyletic origins under domestication: (i) Presence or absence of patterns indicative of founder effects in the cultivated genepool, compared to the amount of variation present in its wild progenitor. (ii) Uniformity or lack of uniformity (within a crop) in genes governing principal domestication traits (traits that were automatically selected for once the wild progenitor was introduced into cultivation). (iii) Species diversity: The number of closely related (congeneric) wild species with similar potential for domestication, native to the area under consideration; and how many of them entered cultivation. The present paper evaluates the information available on the eight crops that founded Neolithic agriculture in the Near East; and arrives at the conclusion that emmer wheat Triticum turgidum L. subsp. dicoccum Schubler, einkorn wheat T. monococcum L., pea Pisum sativum L., and lentil Lens culinaris Medik. were very likely taken into cultivation only once or-at most-a very few times. Also chickpea Cicer arietinum L., bitter vetch Vicia ervilia (L.) Willd., and flax Linum usitatissimum L. seem to have been domesticated in a similar way, but the evidence concerning them is much scarcer. Only for barley Hordeum vulgare L. are there indications that it has been domesticated more than once--but again only a very few times. XAU: The Hebrew University, Jerusalem, Israel.

The seedlings were cultivated for 21 days in Hoagland 3 nutrient solution. At the end of the experiment, shoot and root dry matter was determined and total plant dry mass and shoot to root ratio were calculated. Daily measurements of the leaf length were used for the calculation of the leaf growth rate and phyllochron intervals. Finally, leaf area of individual leaf blades and the nitrogen content of the whole plant were determined. With few exceptions, no statistically significant differences among accessions of Ae. speltoides were found. Compared to these accessions, T. aestivum cv. Sparta produced considerably more dry matter. This was mainly due to larger leaf blade area, while net assimilation rates were similar. It was concluded that the variability among Aegilops provenances is of minor importance and any of the tested accessions could be used as a representative of Aegilops speltoides for further experiments.

CC: F821; F200 AB: Hessian fly, Mayetiola destructor (Say), is the major pest of wheat in North Africa. In Morocco, durum wheat (Triticum turgidum L. subsp. durum (Desf). Husn.) losses due to this pest have been estimated at 32%. Genetic resistance is the only economical and practical means of controlling this insect. Field and greenhouse screening of durum wheat genotypes resulted in the identification of one source of resistance to Hessian fly in Morocco. This is the first source of durum wheat Hessian fly-resistance identified in Morocco. This source of resistance expresses a medium level of antibiosis against first-instar Hessian fly larvae; about 25% of the larvae survive on resistant plants. The deployment of varieties that allow for larval survival on resistant plants should reduce selection for biotype development. This source of resistance is being used by CIMMYT/ICARDA and Moroccan breeders to develop resistant durum wheat varieties. XAU: ICARDA, Aleppo, Syria.

CC: T000; X380 AB: Objectives: To assess whether current smokers eat differently than never smokers and the relation of smoking cessation to dietary change. Design: Population-based survey from 1993-1997. Setting: The Bus Sante 2000, epidemiologic observatory of Geneva, Switzerland. Subjects: A representative sample of 2301 men and 2306 women resident of Geneva, Switzerland. Results: In both genders, compared to never smokers, current heavy smokers (greater than or equal to 20 cigarettes/d) consumed daily less total vegetables proteins (P < 0.03), carbohydrates (P < 0.0001), saccharose (P < 0.01), fibers (P < 0.0001), beta-carotene (P < 0.001), fruit (P < 0.0001) and vegetables (P < 0.04), but they drank more alcohol (P < 0.0001) and more coffee (P < 0.005. In addition, female current smokers ate less energy (P < 0.4), complex carbohydrates P < 0.002), cereals (P < 0.003), vegetables (P < 0.0001) and less iron (P < 0.02). The diet of ex-smokers tended to become more similar to that of never smokers. When longer duration of smoking cessation increased, the consumption of total carbohydrates and complex carbohydrates increased (P < 0.01 and P < 0.06), and alcohol decreased (P < 0.07) in both genders. Conclusions: As in other Western countries, the diet of Swiss smokers appears less healthy than that of never smokers in both men and women, while smoking cessation has beneficial aspect on the quality of the diet. Current smoking appears to have an even stronger effect on the diet of women than on the diet of men. XAU: Geneva University Hospital, Switzerland.

CC: L822 AB: The filarial parasite Setaria digitata is the causative agent of cerebrospinal nematodiasis in its abnormal hosts such as sheep, goats and horses, and therefore is of significant veterinary importance. Since very little is currently known about the biology of this parasite at molecular level we have cloned and characterised a hsp70 gene, the first gene to be reported from this parasite. The genomic clone isolated contained sequences from two hsp70 genes. One gene hsp70-2, was completely sequenced and found to contain nine introns ranging in size from 78 to 195 bp. The region upstream of the initiation codon contained a putative TATA box, two CAAT box elements and three heat-shock elements. A putative transcription initiation site was also identified. The 5' untranslated region contained a splice acceptor sequence. The gene was typically AT rich, having a GC content of 44.5%. The deduced aa sequence potentially encoded a cytosolic protein of 645 aa, which had three consecutive repeats of a tetrapeptide motif, GGMP, at the carboxyl end. The gene appeared to be constitutively transcribed and was not significantly enhanced in response to heat shock in adult worms. Another hsp70 gene (hsp70-1) was located further upstream, arranged in direct tandem with hsp70-2. Southern blot analysis revealed the presence of two or three additional hsp70-related genes in the S. digitata genome. XAU: University of Colombo, Colombo, Sri Lanka.

This technique offers a simple and efficient method of generating both dominant and codominant genetic markers in virtually any eukaryote for mapping and diversity studies.

CC: F200; F700 AB: Study of bread wheat (Triticum aestivum) may help to resolve several questions related to polyploid evolution. One such question regards the possibility that the component genomes of polyploids may themselves be polyphyletic, resulting from hybridization and introgression among different polyploid species sharing a single genome. We used the B genome of wheat as a model system to test hypotheses that bear on the monophyly or polyphyly of the individual constituent genomes. By using aneuploid wheat stocks, combined with PCR-based cloning strategies, we cloned and sequenced two single-copy-DNA sequences from each of the seven chromosomes of the wheat B genome and the homologous sequences from representatives of the five diploid species in section Sitopsis previously suggested as sister groups to the B genome. Phylogenetic comparisons of sequence data suggested that the B genome of wheat underwent a genetic bottleneck and has diverged from the diploid B genome donor. The extent of genetic diversity among the Sitopsis diploids and the failure of any of the Sitopsis species to group with the wheat B genome indicated that these species have also diverged from the ancestral B genome donor. Our results support monophyly of the wheat B genome. XAU: Montana State University, Bozeman, MT.

CC: F200 AB: Pollination with maize is commonly used to produce fertile doubled haploid plants in durum wheat. However, the genetic basis for the ability of parental lines to produce haploid seedlings is not well documented. A maximum likelihood procedure was used to analyse the response of 15 F(1), from a half diallel design involving six inbred lines, and to document rigorously the existence of heritable variation for haploid embryo production. Cross-effects and "general combining abilities" (GCA) were computed to estimate the ability to produce swollen ovaries and viable embryos. On average, the ovary swelling production was 56% and 11% of emasculated flowers produced a viable embryo. For both variables, cross-effect was significant. Based on GCA estimations, the 6 parental lines could be distributed in 3 different groups. The GCA values explained respectively 69% and 79% of the cross-effect for each variable. On the whole, ovary swelling was a poor predictor of embryo formation. No significant correlation was found between the per se values of the 6 parental lines and their GCA.

CC: F200 AB: To refine the current physical map of rice, we have established a restriction fragment fingerprinting method for identifying overlap between pairs of rice yeast artificial chromosome (YAC) clones and defining the physical arrangement of YACs within contiguous fragments (contigs). In this method, Southern blots of rice YAC DNAs digested with a restriction endonuclease are probed with a rice microsatellite probe, (GGC)5. The probe produces a unique fingerprint profile characteristic of each YAC clone. The profile is then digitized, processed in a computer, and a statistic that represents the degree of overlap between two YACs is calculated. The statistics have been used to detect overlaps among YAC clones, thereby filling a gap between two neighbouring contigs and organizing overlapping rice YAC clones into contiguous fragments. We applied this method to rearranging YACs that had previously been assigned to rice chromosome 6 by anchoring with RFLP markers.

CC: F200; F831 AB: A total of 7654 DNA fragments were screened for linkage to wheat powdery mildew resistance gene Pm1c employing fluorescently based AFLP analysis and phenotypic pools from F(3) families. F(3) and derived F(4) families were used for segregation analysis. Pool screening revealed several cosegregating and tightly linked (0.9 cM) AFLP markers for the Pm1c resistance gene. The previously reported RFLP locus Xwhs178 was integrated into the AFLP map in the vicinity of Pm1c. One AFLP marker, 18M2, was determined to be highly specific for the Pm1c gene in diverse genetic backgrounds. As Pm1c allele confers an effective resistance to powdery mildew, the marker 18M2 provides a valuable tool for enhancing marker assisted selection and pyramiding of powdery mildew resistance genes in wheat.

CC: F200; F700 AB: We used PCR to obtain phylogenetically informative sequences from the high molecular weight glutenin genes of wheat. The validity of partial sequence comparisons as a means of studying glutenin phylogenetics was established by constructing neighbour-joining trees from partial alignments of 12 published glutenin allele sequences. PCR was then used to obtain 20 novel glutenin allele sequences from various Triticum and Aegilops species, including a 3000 year old preserved wheat. A neighbour-joining tree derived from all known glutenin allele sequences had eight clades, representing the eight loci from which the allele sequences were derived, and was split into two halves, one comprising alleles from the Glu-1-1 loci and the other comprising Glu-1-2 alleles. The topology was compatible with the postulated relationships between the A, B, D, and G genomes. The Glu gene duplication event was tentatively dated at 7.2-10.0 million years ago (MYA), the origin of the four genomes at 5.0-6.9 MYA, and the split between the B and G genomes at 2.5-3.5 MYA. The Glu-B1-1 alleles in cultivated wheats fell into two subgroups that diverged 1.4-2.0 MYA, suggesting that emmer was domesticated twice. The D allele sequences were relatively diverse, indicating that the hybridization event that resulted in the hexaploid bread wheats might have occurred more than once.

CC: F200; F833; F821 AB: The genomic origin of alien chromosomes carrying resistance to wheat streak mosaic virus (WSMV) and the wheat curl mite (WCM), Aceria tosichella Keifer, was evaluated in nine wheat-alien addition, substitution, or translocation lines, derived from hybrids of wheat with Thinopyrum ponticum (Podp.) Barkworth & D.R. Dewey (2n = 10x = 70), or with Th. intermedium (Host) Barkworth & D.R. Dewey (2n = 6x = 42). One of the four wheat x Th. ponticum lines was resistant to WSMV and WCM. The other three lines were resistant to WCM, but susceptible to WSMV. Five wheat x Th. intermedium lines were susceptible to WCM, but were highly resistant to WSMV. Genomic in situ hybridization (GISH) using different genomic DNA probes demonstrated that all WSMV- and WCM-resistant lines carried an alien chromosome(s) related to the J(s) genome in Th. ponticum and Th. intermedium. The J(s) alien chromosome(s) displayed a special GISH hybridization pattern with the S genomic DNA probe, in which S genome DNA hybridized strongly in the centromeric regions and occasionally in the terminal regions with no or a weak hybridization signal in the middle of the two arms of the chromosomes. The WCM-resistant wheat x Th. ponticum lines N/5.10.10 and 63-30-2-2-2-8-1 carried the same short arm of chromosome 6J(s) derived from the partial amphiploid Agrotana, while the WSMV-resistant wheat x Th. intermedium lines T-Ai, CI15092, CI17766, A29-13-3-1 and KS93WGRC27 all had the same alien chromosome or chromosome arm of 4J(s) from Th. intermedium. The J(s) genome present in Th. ponticum and Th. intermedium is an important source of WSMV and WCM resistance that can be transferred into wheat.

The chromosomal location of the landmark signals was determined by FISH to a barley trisomic series using the 18S and 5S probes labeled with different fluorophores. The utility of these FISH landmarks for barley physical mapping was also demonstrated when an Amy-2 cDNA clone and a BAC clone were hybridized with the FISH landmark probes.

CC: F200 AB: One-hundred and nineteen progeny plants of crosses between one Hordeum lechleri (2n = 6x = 42) accession and the barley varieties 'Wong' and 'Igri' comprised 54 euploids (2n = 28), 8 hyperploids (2n = 29), 46 hypoploids (2n = 22-27), and 11 polyhaploids (2n = 21). Giemsa C-banding showed most interplant chromosome variation to be caused by elimination or, more seldom, duplication of barley chromosomes. The chromosomes of 'Wong' were preferentially lost in the order, 1H-4H-5H-3H-7H-2H-6H (5-4-7-3-1-2-6); those of 'Igri' in the order, 1H-3H or 6H-7H or 5H or 4H-2H (5-3 or 6-1 or 7 or 4-2), indicating different patterns of elimination. Over years chromosome elimination may be continuous. Hypoploid genomes of 'Wong' had the chromosomes arranged in the order, 1H-5H-2H-6H-7H-3H-4H (5-7-2-6-1-3-4), with a discontinuity between chromosomes 1H(5) and 4H(4); whereas in 'Igri' the order was (1H)-5H-2H-4H-7H-6H-3H-(1H) ((5)-7-2-4-1-6-3-(5)) with a discontinuity at 1H(5), indicating varietal differences. The patterns of barley chromosome elimination may be derived from chromosome orders. Elimination starts with a chromosome at the discontinuity, continues with the chromosome at the other end of the order, and proceeds more or less alternately towards the middle. In hybrids including 'Wong', duplication affected the two chromosomes situated at either end of barley chromosome order. A few older hybrids with 2n = 21 had three or four H. lechleri chromosomes substituted for as many barley chromosomes suggesting homoeology. Our observations support the hypothesis of an orderly arrangement of the chromosomes within genomes (Bennett 1981), but they do not agree with the idea of one 'natural. karyotype' for each species (Bennett 1984b).

CC: F200 AB: Although extensive synteny between hexaploid wheat and rice chromosomes has been demonstrated, synteny between the species breaks down in several regions of the wheat genome carrying agronomically important genes. A possible relationship between the wheat Vrn-A1, the vernalization response gene on chromosome 5A, and the rice Hd-6, a QTL controlling heading date by photoperiod response on chromosome 3, was investigated. Rice cDNA clones which had previously been mapped onto the Hd-6 region were screened for comparative genetic mapping of the Vrn-A1 region. Ten markers mapped to Hd-6 were assigned to wheat chromosome 5A by nullisomic-tetrasomic analysis. Of them, four cDNA markers, linked within 2.2 cM in the rice Hd-6 region, were mapped on the flanking region of the wheat Vrn-A1, with a complete correspondence of order, demonstrating a fine-scale genetic collinearity. These results gave evidence that the wheat Vrn-A1 region is in synteny with the rice Hd-6 region. XAU: Obihiro University of Agriculture and Veterinary Medicine, Obihiro, Japan.

Using an EDTA-BPDS method, Fe(II) and Fe(III) on the surfaces of roots sampled from various environments were stabilized, extracted and determined simultaneously. The proportion of extracted Fe(II) to total Fe ranged from 0.17 to 0.65 for the roots grown in constructed wetlands, fields, and hydroponic culture; and from 0.34 to 0.70 for different sections of wetlands plant roots. The observed results suggested that De plaque is caused not only by rhizosphere oxidation, but also by Fe(II) compound formation on the root surfaces. XAU: University of Florida, Homestead, FL.

CC: J700; J200 AB: We hypothesized that the four rotation crops: wheat (Triticum aestivum L.), sorghum [Sorghum bicolor (L.) Merr.], lablab [Lablab purpureus (L.) Sweet] and mung bean [Vigna radiata (L.) R. Wilczek] differ in their ability to repair soil structure. The study was conducted on a Typic Haplustert, Queensland, Australia, locally termed a Black Earth and considered a prime cropping soil. Large (0.5-m depth by 0.3-m diam.) soil cores, collected from compacted wheel furrows in an irrigated cotton (Gossypium hirsutum L.) field, were subjected to three, six, or nine wet-dry cycles that simulated local flood irrigation practices. After each cycle, soil profiles were sampled for clod bulk density, image analysis of soil structure, and evapotranspiration. Generally, all crops improved soil structure over the initial field condition but lablab and mung bean gave improvements to greater depths and more rapidly than wheat and sorghum. Mung bean and lablab caused up to a threefold increase in clod porosity in the 0.1- to 0.4-m soil layer after only three wet-dry cycles, whereas sorghum required nine wet-dry cycles to increase clod porosity in only the 0.2- to 0.3-m layer, and wheat gave no improvement even after nine wet-dry cycle. Image analysis of soil structure showed that lablab and mung bean rapidly (by three wet-dry cycles) produced smaller peds with more interconnected pore space than wheat and sorghum. By nine wet-dry cycles, sorghum achieved deep cracking of the soil but the material between the cracks remained large and dense. Evapotranspiration was double under lablab and mung bean compared with wheat and sorghum. Our results indicate greater cycles of wetting and drying under lablab and mung. bean than wheat and sorghum that have led to rapid repair of soil compaction.

CC: J200; J700 AB: Comparisons of bulk density between no-till and chisel management systems have produced conflicting results in different studies. These conflicting results have been due to averaging across large depth increments (up to 30 cm) and by ignoring traffic patterns when sampling. A few studies have measured 2-cm depth increments for soil from tilled plots, but few, if any, have measured 2-cm incremental soil properties from no-till and compared them with similar measurements from tilled management systems. The objective of this study was to compare no-till and chisel management system effects on 2-cm increments of the vertical soil properties both for sites with and without controlled wheel traffic in corn (Zea Mays L.)-soybean [Glycine max (L.) Merr.] rotation. The controlled traffic site coated of Muscatine (Fine-silty, mixed, mesic, Aquic Hapludoll) and Tama (Fine-silty, mixed, mesic Typic Argiudoll) soils, and the site without controlled traffic had Downs soil (Fine-silty, mixed, mesic Mollic Hapludalf). We collected soil samples in 2-cm increments to the 30-cm depth. On controlled traffic plots for the 0- to 2-cm increment, soil bulk density from no-till plots was less than from chisel plots for half of the cases, but for the 6- to 18-cm depths, soil from no-till was more dense than soil from chisel plots 61% of the time. There was no significant soil bulk density difference between tillage treatments for plots without controlled traffic. Results of tillage on residue, organic C, and crop yield were inconsistent. Chisel management did not result in less dense soil than no-till unless traffic was carefully controlled. XAU: National Soil Tilth Laboratory, USDA, ARS, Ames, IA.

A spring wheat (Triticum aestivum L.)-fallow (SW-F) system was compared with a spring wheat-winter wheat-sunflower (Helianthus annus L.) (SW-WW-SF) system on a Temvik-Wilton silt loam (fine-silty, mixed Typic and Pachic Haploborolls) at three N rates (0, 22, and 45 kg ha(-1) foe SW-F and 34, 67, and 101 kg ha(-1) for SW-WW-SF) under conventional, minimum, and no-tillage. After 10 yr, soil samples were incubated to determine N-mineralization rates. Cropping intensity, N rate, and tillage intensity interacted to affect N-mineralization rates.

In spring wheat, N-mineralization rates in 0- to 0.05-m depth soil were 9.9 +/- 0.8 kg ha(-1) wk(-1) in the SW-WW-SF system vs. 5.6 +/- 0.4 kg ha(-1) wk(-1) in the SW-F system and in the 0.05- to 0.15-m depth were 3.6 +/- 0.1 kg ha(-1) wk(-1) in the SW-WW-SF system vs. 2.4 +/- 0.2 kg ha(-1) wk(-1) in the SW-F system. Within the SW-WW-SF system, N-mineralization rates in the 0- to 0.05-m soil layer were 6.8 +/- 0.5 kg ha(-1) wk(-1) under winter wheat vs. 9.9 +/- 0.8 kg ha(-1) wk(-1) under spring wheat and 9.2 +/- 0.6 kg ha(-1) wk(-1) under sunflower. In the 0.05- to 0.15-m soil layer, N-mineralization rates were 3.3. +/- 1.0 kg ha(-1) wk(-1). More intensive cropping and conservation tillage increased N-mineralization rates in this soil and may ameliorate the decline in N fertility associated with crop-fallow systems.

CC: J200; F120; J700 AB: Continuous cropping or decreasing the frequency of summer fallow (F) in cereal-based dryland rotations may have benefits other than greater water utilization and erosion control. We hypothesized that rotations with no fallow or minimum fallow frequency can produce more biomass and cover than the traditional winter wheat (Triticum aestivum L.)-summer fallow systems (W-F), and ultimately, greater amounts of soil organic matter (SOM). To this end, we evaluated changes in various pools of SOM at the 0- to 5- and 0- to 15-cm depths on a Weld loam (fine, smectitic, mesic aridic Paleustolls) that were caused by (i) decreasing fallow or increasing cropping intensities, (ii) specific rotations of the same length but with different crop sequencing, and (iii) accumulated residue and roots from reduced- or no-tillage from 1993 to 1997. Total soil organic carbon (SOC) and N for the 0- to 5-cm depth increased by approximately equalt to 20% with continuous cropping rotations compared with W-F rotations. Particulate organic matter-carbon (POM-C) doubled, while POM-N, and soluble organic C (OC) increased by one third for the same comparison. At the 0- to 15-cm depth, SOC, POM-C, and POM-N did not differ among systems with fallow, nor among systems with cropping intensities greater than W-F. Thus, significant differences always existed between W-F and continuous cropping. Generally, fallow had a negative influence on SOC accumulation, and continuous cropping a positive influence on surface SOM. Changes in SOC did not correlate with yields in the five-year comparison of this ongoing study. XAU: USDA, ARS, Akron, CO.

CC: J500; F120; J700 AB: Cycling of N through an agroecosystem can be managed more effectively if effects of N management and cropping sequence on soil N microbial processes are understood. Effects of cropping intensity and N fertilizer rate on net soil N mineralization were studied as well as their correlation with precipitation, air temperature and soil water content. Net soil N mineralization was measured by incubating undisturbed soil cores (15-cm depth) containing anion and cation exchange resins at their bottoms. Cores were incubated during each of five time periods (3-4 wk each) during the fallow phase (mid-April to mid-September) of two no-till cropping systems, wheat (Triticum aestivum L.)-fallow (WF) and wheat-corn (Zea mays L.)- fallow (WCF). Past N fertilizer applications were over four rates with total amounts applied during the previous 6 yr of 0, 95, 190, and 286 kg N ha(-1) in WF and 0, 134, 269, and 403 kg N ha(-1) in WCF. Soils were an Aridic Paleustoll at Sterling and an Aridic Argiustoll at Stratton in eastern Colorado. Total net N mineralization in WCF was half that in WF (22 vs. 43 kg N ha(-1); 2-site average), probably due to greater immobilization as evidenced by nearly three times greater accumulation of crop residue on the soil surface after 6 yr of no-till management. Greater conservation of applied N and soil N can be expected in the more intensive WCF system. Total mineralized N increased with N rate by approximately equal to 0.2kg ha(-1) for each kg ha(-1) of previously applied N. Precipitation in combination with air temperature and their interaction term gave the best prediction of average daily N mineralization at both sites. XAU: USDA-ARS, Sidney, MT.

CC: J100; F500 AB: Rice (Oryza sativa L.) genotypes with a high ability to support biological N(2) fixation are of interest because they would enhance N gains in the rice-soil system without changing existing cultural practices. Pot experiments were conducted in a greenhouse during the 1994 wet season to determine the amount of N(2) derived from the atmosphere (Ndfa) by 10 rice genotypes grown in three soils with varying levels of initial soil-NH(4)(+)-N. Enriched (15)N and natural abundance delta(15)N dilution methods were employed. Flooded soils were puddled with and without 99.5 atom (15)N%-labeled urea to minimize spatial variation of the isotope. The integrated (15)N enrichment of plant available N, calculated using a model that accounts for temporal changes in the isotopic composition, was used as a reference to estimate genotypic differences in Ndfa. The (15)N enrichment of soil available N declined exponentially and was half the original level at 122d. The delta(15)N values correlated with atom (15)N% excess of enriched (15)N for the rice genotypes grown in two out of three soils. Percentage Ndfa for the genotypes across three soils ranged from 4.2 to 32.2 when calculated using as a reference plant, and from 10.8 to 35.9 when calculated using (15)N enrichment of soil available N as a reference. Genotypic differences were significant and more pronounced at low soil-NH(4)(+)-N (11 mg kg(-1)) than at higher soil-NH(4)(+)-N (79 and 92 mg kg(-1)); they ranged from 14.9 to 35.9% at low N and from 10.8 to 23.6% at high N. Some genotypes consistently gave either high or low Ndfa. Because of the low levels and narrow range of genetic differences in associative N(2) fixation, the. potential for its improvement through breeding appears to be limited.

The most abundant naturally occurring fumonisin, fumonisin B1 (FB1), has been shown to induce several animal disease syndromes. The development of analytical methods is therefore important. A new method is described that integrates extraction and purification of maize samples in one step. It efficiency is compared against well-known methods, and shows similar results for naturally contaminated maize. It is concluded that the proposed method can be applied to fumonisin B1 and fumonisin B2 (FB2) analysis in maize at least within the concentration range found.

CC: Q204; Q504; F831 AB: Unusual wet and cool weather conditions during the 1994 growing season in Maryland and Delaware resulted in a severe outbreak of Fusarium graminearum on sweet corn ears ('Moore' variety') prior to harvesting and canning. The number of ears visibly infected with Fusarium spp. ranged from less than 5% to 25% in some fields. Injection typically occurred at the tassel end of the ears. Fusarium graminearum was isolated from surface disinfected kernels, both those which were visibly infected and those kernels which appeared disease-free in an area up to 5 cm from the edge of the visibly moulded areas. Infected ears were cut into four sections and the kernels only were analysed for deoxynivalenol (DON) using liquid chromatography (LC) and mass spectrometry/gas chromatography (GC/MS). Kernels from the visibly mouldy area of the ears contained DON at levels of approximately 446 mg/g DON on average; whereas in the nonvisibly infected portion of the ears adjacent to the mouldy tips, DON levels averaged approximately 10 mg/g. Sections of ears closest to the base contained no detectable DON or less than 1 microgram/g. This is the first reported natural occurrence of the mycotoxin DON in sweet corn prior to harvest and canning. XAU: University of Maryland, College Park, MD.

CC: L500; L600 AB: The potential use of faecal n-alkanes for estimation of intake and diet composition over periods of 1-2 days was assessed in two experiments. The aim was to determine the accuracy with which intake and diet composition could be estimated by characterizing faecal excretion of n-alkanes following a discrete dose as opposed to steady state kinetics used in previous work. In the first experiment, 16 sheep were fed mixtures of spinach (rich in C31-alkane) and cabbage (rich in C29-alkane) in known proportions and amounts for two days. Artificial n-alkanes (C28- and C32-alkane) were dosed on four occasions during this time. Total intakes were controlled at 0.2, 0.3, 0.4 or 0.5 kg dry matter (DM) per day and nominal amounts of spinach offered (as a proportion of the total diet) were 0.00, 0.15, 0.30 and 0.45. Each sheep received a unique combination of intake and dietary proportions (four intake rates x four proportions). Sheep were fed fresh grass (timothy, Phleum pratense) before and after feeding spinach and cabbage. Sequential rectal grab samples of faeces were collected at regular intervals and total faecal collections were carried out over 144 h from the start of the spinach/cabbage feeding period to obtain samples for n-alkane analysis. In the second experiment, fresh grass was sprayed with two combinations of artificial n-alkanes (C24- and C32- or C28- and C36-alkane) and fed to 16 sheep over a 24 h period. Each sheep received one of four intake rates (0.8, 1.0, 1.2 or 1.4 kg DM/day) and, within intake rates, each sheep received one of four different proportions of the herbage sprayed with the combinations of n-alkanes (0.2, 0.4, 0.6 or 0.8), in a similar fashion. to the first experiment. In order to estimate intake, C26- and C34-alkanes were dosed at the start of the feeding period. Faecal sampling procedures were the same as those in the first experiment. Different parameters of faecal excretion curves of dosed and natural n-alkanes were used to estimate dietary proportions and intake. Parameters tested included area under the excretion curve and curve maximum. Dietary proportions were calculated using an iterative minimization procedure employing faecal and herbage n-alkane concentrations. Intakes were estimated using ratios of dosed:natural faecal n-alkanes. The best estimates of dietary proportions were obtained using faecal concentrations at a single point in time in both experiments (> 80% variation explained for regressions of estimated v. actual proportions). Intake estimates required the calculation of the area under the excretion curve to obtain acceptable estimates (70-90% variance explained for regressions of estimated v. actual intakes in Expt 2). The experiments demonstrate that precise estimates of diet composition can be obtained using single faecal samples following consumption of simple herbage mixtures over 24-48 h. Intake may also be estimated using this technique provided that a series of faecal samples are collected over 4-5 days following the period of ingestion.

CC: J500; L100; F500; L500 AB: Nitrogen (N) inputs and outputs were measured over 3 years in a trial with four farmlets (each with 16 randomly-allocated 0.4 ha paddocks) on permanent white clover/ryegrass pastures which were grazed throughout the year by dairy cows near Hamilton, New Zealand. Three farmlets were stocked at 3.3 cows/ha and received nominal rates of N fertilizer (urea in 8-10 split applications) of 0, 200 or 400 kg N/ha per year. A fourth farmlet with 4.4 cows/ha received 400 kg N/ha per year and was supplemented with maize grain during the first two years. Nitrogen balances were calculated, with sigma N inputs approximately sigma N outputs. Annual inputs from N2 fixation were 99-231 kg N/ha in the 0 N farmlet, but declined to 15-44 kg N/ha in the 400 N farmlets. The main N outputs (in kg N/ha per year) were in milk (72-126), nitrate leaching (20-204), and transfer of N via cow excreta from pastures to lanes and milking shed (54-92). Gaseous losses by denitrification (3-34) and volatilization (15-78) were smaller than the other N outputs but increased significantly with N fertilizer application. In the maize-supplemented farmlet, N outputs in milk were 31% higher than in the corresponding non-supplemented 400 N farmlet, whereas leaching losses averaged 17% lower during the 2 years of supplementation. In the N-fertilized farmlets, estimated N balances were influenced by inclusion of the transitional N processes of immobilization of fertilizer N into the soil organic N pool (estimated using 15N at 42-94 kg N/ha per year) and the contribution from mineralization of residual clover-fixed N in soil not accounted for in the current estimates of N2 fixation (estimated at up to 70% of measured N2. fixation or 46 kg N/ha per year). However, these processes were counteracting and together were calculated to have only a small net effect on total N balances. The output of N in products (milk, meat and feed) relative to the total N input averaged 26% in the 400 N farmlets, and is compared to that measured for commercial intensively-managed dairy farms in England and the Netherlands (14-20%). The 0 N farmlet, which was reliant on N2 fixation as the sole N input, was relatively very N-efficient with the milk production being 83% of that in the 400 N farmlet (at 3.3 cows/ha) and the N output in products relative to total N input averaging 52%.

CC: L500 AB: In order to learn more about the feeding value of stovers and straws, seven diets were compared in one experiment and nine in another. The diets in the first experiment were: the upper and lower parts of lucerne (Medicago sativa) hay, the leaves, upper stem and lower stem of maize (Zea mays) stover and the leaves and stem of sorghum (Sorghum vulgare) stover. The diets in the second experiment were: the upper and lower parts of lucerne hay, the leaves, stem and whole stover of millet (Setaria italica), the straw and chaff of wheat (Triticum aestivum), rice (Oryza sativa) straw and sweet potato (Ipomoea batatas;) haulm. The diets were fed to sheep to record rate of intake, voluntary intake and in vivo digestibility. The diets were analysed for cell wall (as neutral detergent fibre), crude protein and lignin. Organic matter degradation and cell wall degradation were recorded in nylon bags in the rumen of cattle. The highest rates of intake (6.8-9.6 g dry matter/min) and voluntary intake (75-103 g dry matter/kg W0.75/day) were with sweet potato haulm and the upper, leafy part of lucerne hay. The voluntary intake of millet leaves, wheat chaff and the lower, stemmy part of lucerne hay was moderately high (46-70 g dry matter/kg W0.75/day). Voluntary intake of leaves was higher than that of stems in the case of millet, sorghum and to a lesser extent maize. The lowest rates of intake were with millet stem, sorghum stem and rice straw (1.8-2.4 g dry matter/min). In vivo digestibility of organic matter was highest (59-67%) for the upper part of lucerne hay, sweet potato haulm, the lower part of maize stem and millet leaves. The leaves of maize were less digestible than the stem, while the reverse. was the case with millet. Cell wall content was particularly high (74-78% of dry matter) in millet stem, wheat straw and chaff, rice straw and sorghum stem. Lignin content was low (3.6-4.2% of dry matter) in millet leaves, maize leaves and the upper part of maize stem. Organic matter degradation after 24 h incubation in the rumen was highest (80%) in sweet potato haulm and lowest (39-44%) in millet stem, wheat straw and chaff and rice straw. Cell wall degradation after 96 h in the rumen was highest (76-81%) with the leaves of maize, sorghum and millet and lowest (40-59%) with lucerne hay, millet stem and stover, wheat straw and chaff and rice straw.

CC: J500; F120; F600 AB: The potential for using crop wastes as a source of nutrients on the yields of rice grown under submerged conditions was studied in both field and pot experiments at the Experimental Farm of the Agricultural and Food Engineering Department, Indian Institute of Technology, Kharagpur during 1992/93 and 1993/94. The application of groundnut haulm at 3.0 t/ha, maize stover at 5.0 t/ha, mustard stover at 3.0 t/ha and green manure at 1.5 t/ha contributed considerable amounts of nutrients, which improved components of yield, yield and nutrient uptake by rice and also improved the organic carbon (OC) content and available N, P and K in the soil. Yields and soil fertility were both further improved when these organic materials were combined with inorganic fertilizer to supply the recommended amounts of nutrients, except that inorganic fertilizer alone did not cause an increase in the OC content of the soil. In the pot experiment, the production of NH4-N and NO3-N was both larger and more consistent when organic and inorganic nutrient sources were added together than when inorganic sources alone were used.

CC: F600; F500; J500 AB: A comprehensive study was conducted over a 4-year period (1984-87) to evaluate the water use, growth and yield responses of pearl millet (Pennisetum glaucum (L.) R. Br.) cv. CIVT grown with and without fertilizer (30 kg P2O5 and 45 kg N ha-1) at the ICRISAT Sahelian Centre, Sadore, Niger. Our study showed significant year and fertilizer effects on the growth and yield of millet at the study site. Observed year effects were primarily due to the variations in the amount and distribution of rainfall in relation to the potential demand for water. During 1984, 1985 and 1987, total rainfall was below the long term average, while in 1986 it was above average. While the onset of rains (relative to the average date of onset) was early from 1984 to 1986, in 1987 the sowings were delayed by as much as 33 days. Of all the four years, the separation between the treatments in the cumulative evaporation is most evident for 1984, which was a drought year with below-average rainfall in all the months from June to September. Cumulative evaporation patterns in 1985 and 1986 were similar because of regular rains and high average rainfall per rainy day from June to October. In 1987, sowings were delayed until 15 July and only 6.9 mm of rainfall was received per rainy day in July. Hence cumulative evaporation was initially low and showed a significant increase only after two significant rain events in early August. There was a large response to fertilizer in all the years as small additions of fertilizer phosphate increased the soluble phosphate in the soil. Fertilizer application resulted in a small increase in water use (7-14%) in all years except 1987. Increased yield due to the application of fertilizer. was accompanied by an increase in the water-use efficiency (WUE) in all the four years with the largest increase in 1985. The beneficial effect of fertilizers could be attributed to the rapid early growth of leaves which can contribute to reduction of soil evaporative losses and increased WUE. Over the four seasons, average increase in the WUE due to the addition of fertilizer was 84%. XAU: World Meterological Organization, Geneva, Switzerland.

CC: J500; J700; J100 AB: Soil sampling in autumn gives important information on the soil N dynamic. In the growing seasons 1991/92 to 1995/96, the effects of different crop management systems on soil mineral N (NO3-N plus NH4-N:N(min) were investigated in a factorial field experiment at Hohenschulen Experimental Station near Kiel in NW Germany. The crop rotation was oilseed rape--winter wheat--winter barley, and soil tillage (conservation tillage without ploughing, conventional tillage), application of pig slurry (none, autumn, autumn + spring), mineral N fertilization (0, 120 and 240 kg N ha-1) and fungicide application (none, three applications) were all varied. Each year, the treatments occurred in all three crops of the rotation and were located on the same plots. N(min) was determined on four dates ('After drilling', 'End of autumn growth' before winter, 'Beginning of spring growth' before N fertilizer application, and 'After harvest') to 90 cm in 30 cm horizons. Under all crops, N(min) showed a large year to year variation. Highest values of 132 kg N ha-1 were observed 'After drilling', which decreased until 'End of growth'. The increase of autumn N(min) ('After drilling', 'End of autumn growth') was mainly due to autumn slurry, whereas mineral N fertilizer mainly affected N(min) 'After harvest'. Soil tillage and fungicide application only slightly modified N(min) at all dates. The relationship between N leaching and N(min) measured either 'After drilling' or at the 'End of autumn growth' in 1991/92-1994/95 remained too poor to be used to estimate N leaching. N net mineralization during autumn and winter varied with crops, as estimated by the N(min) changes between 'After drilling' minus. 'Start of spring growth' plus N uptake by the crop at 'Start of spring growth' plus N leaching during winter. On average over the years, 39 kg N ha-1 were mineralized under oilseed rape and 42 kg N ha-1 under wheat compared with 31 kg N ha-1 under barley. However, a large year-to-year variation occurred. In addition, the ranking of the years differed with the crops. Slurry application led to different amounts of mineralized N. Under barley only 25 kg N ha-1 were calculated for the autumn slurry, but 42 kg N ha-1 for the autumn plus spring slurry treatment. In contrast, under oilseed rape the highest value of 41 kg N ha-1 occurred in the autumn slurry plots. Under wheat, slurry application only slightly affected N mineralization. Increased mineral N fertilization decreased N release under oilseed rape, but significantly increased it under cereals. Application of fungicides did not affect N mineralization during winter.

CC: Q104 AB: A review of applications of finite element techniques in the calculation of stress distributions in grain kernels during moisture desorption and adsorption is given. In the analysis presented in this paper, the rice kernel was assumed to be a linear viscoelastic ellipsoid body. The model simulated the expansion of the rice kernel and evaluated the magnitude of the local strains and stresses. The finite element method was used to obtain a numerical solution to the stress-strain relationship. For determining fissure initiation and propagation, the failure criterion based on local strain energy density of distortion was used. For stress analysis the maximum or ultimate tensile strength criterion was used. Simulations resulting from the model were compared with the experimental results.

CC: J500; F600; F500 AB: Acidification of cattle slurry with nitric acid to pH 4.5 was studied on experimental dairy farms in the Netherlands as a measure to reduce ammonia losses. This paper presents the results of two field experiments, carried out to assess the utilization of nitrogen (N) from nitric acid treated cattle slurry following surface application to grassland. Three aspects were studied: (i) the utilization of N from nitric acid treated cattle slurry following a single surface application to grassland: (ii) the effects of multiple applications of nitric acid treated cattle slurry on N utilization, residual inorganic N in the soil and sward quality: and (iii) the residual effects of nitric acid treated slurry on DM and N yield. In these experiments undiluted acidified slurry (UAS) and diluted acidified slurry (DAS) were compared with calcium ammonium nitrate (CAN). Apparent N recoveries (ANR) and apparent N efficiencies (ANE) were calculated on the basis of inorganic N in applied fertilizer and slurries. Following single applications of UAS and CAN on the sward on the clay soil, the average ANR values of UAS and CAN were 0.74 and 0.75 kg kg(-1), respectively. The average ANE values of UAS and CAN were 30.3 and 29.5 kg DM per kg N, respectively. Single applications of DAS and CAN on the sandy soil resulted in average ANR values of 0.65 and 0.84 kg kg(-1) and average ANE values of 24.1 and 29.2 kg DM per kg N for DAS and CAN, respectively. On average, the direct ANR values after four successive applications of CAN, UAS or DAS were 0.82, 0.82 and 0.74 kg kg(-1), respectively and the direct ANE values were 28.4, 27.8 and 27.0 kg DM per kg N. On the sandy soil, the amount of residual. inorganic N in the soil after the 4th cut increased with increasing rates of inorganic N application, with a slightly higher amount on plots treated with acidified slurry than on plots fertilized with CAN. On the clay soil, the amount of residual inorganic N was not affected by N application rate nor N source. On average, the residual ANR values, in the unfertilized 5th and 6th cuts, of CAN, UAS or DAS were 0.08, 0.10 and 0.09 kg kg(-1), respectively and the residual ANE values were 2.7, 3.3 and 3.0 kg DM per kg N. It was concluded that nitric acid treated cattle slurry is an effective N fertilizer on grassland and that the residual effect of nitric acid treated cattle slurry is only marginally higher than that of CAN. Repeated applications of nitric acid treated cattle slurry did not affect sward composition. XAU: Research Station for Cattle, Sheep and Horse Husbandry, Lelystad, the Netherlands.

CC: J500; F600; F120; F500 AB: A field study using 15N was conducted on a Vertisol in semi-arid Morocco to assess the fate and efficiency of fertiliser N split applied to winter wheat (Triticum aestivum L.). Splitting of fertiliser N is highly crucial in semiarid regions, considering the increased moisture stress towards the end of the growing season. A N fertilisation rate of 100 kg N ha(-1) was split according to two schemes: i) 25% at planting, 50% at tillering and 25% at stem elongation; or ii) 50% at tillering and 50% at stem elongation. The application of 100 kg N ha(-1) increased the vegetative dry matter production with more than 2000 kg dry matter ha(-1) in comparison with the control treatment. Nitrogen fertilisation had no significant effect on the grain yield production. Moreover, the 1000 grain weight decreased from 32 to 26 g due to N fertilisation. Total N uptake was about 50 kg N ha(-1) higher for the fertilised plants in comparison with the unfertilised plants, but it was not affected by the splitting pattern of the fertiliser N. Recoveries of 15N-labelled fertiliser by the plant (above-ground plant parts plus roots from the upper 20 cm layer) were low (31% and 24% for the 3-split and 2-split application, respectively). More N in the plant was derived from fertiliser when applied early in the growing season than when applied late in the season. About 13% of the N in the plants was derived from the 50 kg N ha(-1) at tillering, while only 5% was derived from the N application (50 kg N ha(-1) at stem elongation. At harvest, a high residual of fertiliser-derived N was found in the 0-90 cm profile (62% and 72%, for the 3-split and 2-split application, respectively). Less than 10% of the applied N could not. be accounted for, the amount being highest for the application at tillering. This N not accounted for was mainly ascribed to denitrification after an important rainfall event. The application of fertiliser N led to an increase of about 20 kg N ha(-1) in soil N uptake by the crop (positive ANI). The results suggested a dominant influence of moisture availability on the fertiliser N uptake by wheat. XAU: National School of Agriculture, Meknes, Morocco.

CC: J500; F600; J200; F120 AB: Phosphorus fixation results in low P use efficiency in acid soils. Increase in soil pH through urea hydrolysis may improve P availability and use efficiency. Growth chamber and field experiments were conducted to evaluate effects of urea on triple superphosphate (TSP) transformation and P use efficiency. A Ste. Rosalie clay (Typic Humaquept), an Ormstown silty clay loam (Typic Humaquept) and a Chicot sandy clay loam (Typic Hapludalt) were used in the growth chamber experiment with three rates of N (0, 200 and 400 mg N kg(-1)), two N sources, either urea or NH4 NO3, based on 87 mg P kg(-1) soil. In the field, three rates of urea (0, 60 and 120 kg N ha(-1)) and two rates of TSP (26 and 52 kg P ha(-1) were compared on a Ste. Rosalie clay and an Ormstown silty clay loam. Compacted or blended mixtures of urea-TSP with different ratios of N:P were used in the field experiment. In the growth chamber experiment, soil pH and dissolved organic carbon (DOC) concentration was increased by added urea, and Mehlich (3) and water extractable P thus increased with increased urea. Soil pH, DOC and available P levels were not significantly affected by added NH4 NO3. Phosphorus uptake increased with added N, either urea or NH4 NO3, but P concentration increased only with addition of urea. In the field, soil Mehlich (3)-P at day 20, P uptake and use efficiency, corn yields increased when urea was applied with TSP. Compacted mixtures of urea-TSP increased P uptake and use efficiency, corn yields in comparison with blended mixtures. The beneficial effects of banded urea with TSP on P availability and P use efficiency were primarily attributed to urea hydrolysis, subsequent pH. increase and organic matter dissolution as well as synergistic effect of N and P. These results indicate that compaction of urea plus TSP may offer a significant advantage over blended mixtures. XAU: McGill University, Ste Anne de Bellevue, QC, Canada.

CC: W000; J100; F600 AB: Methane emissions from flooded rice grown under greenhouse conditions were monitored using a closed chamber technique. The three rice cultivars showed similar diel emission patterns though the amplitudes differed. Variation in emissions maximum emission rate from the different cultivars ranged from 0.164-0.241 mg/pot/h at tillering stage, 0.714-2.334 mg/pot/h at heading stage, 0.399-1.393 mg/pot/h at ripening stage. The methane emissions increased in the morning at accelerating rates, reached a maximum in the early afternoon, then decreased rapidly to constant rates during the night. The diel emission pattern was modeled a Gaussian equation for daytime, and a constant for nocturnal emissions. Applying an Arrhenius equation, more than 90% of the diel variation of methane emissions could be predicted from soil temperature fluctuations. The predictions improved by using a diffusion model based on soil temperature and dissolved methane concentrations in soil solution. Soil temperature and methane concentration in soil solution are the two major factors control line diel methane emissions. XAU: Institute of Crop Breeding and Cultivation, Beijing, China.

CC: J500; F600; F120 AB: The recovery of soil mineral nitrogen N by crops, and its subsequent utilisation for dry matter (DM) production may be increased when the application of N is postponed until after crop emergence. The significance of this strategy for silage maize was studied in nine field experiments on Dutch sandy soils from 1983 to 1988. In five experiments the effect of slurry applied before planting at a rate of circa 66 m3 ha(-1), was compared to the effect of a similar rate of which half was applied before planting and half at the 4-6 leaf stage. In the 4-6 leaf stage slurry was either injected or banded. In four other experiments the effect of mineral fertilizer-N splitting was studied. In these experiments, 30 m3 ha(-1) cattle slurry, applied before planting, was supplemented with mineral fertilizer-N at rates ranging from 40 to 160 kg ha(-1), either fully applied before crop emergence or split. When split, 40 kg ha(-1) of the mineral fertilizer-N rate was banded at the 4-6 leaf stage. According to balance sheet calculations, substantial losses of slurry N and mineral fertilizer-N occurred during the growing season. Losses were compensated for, however, by apparent mineralization, ranging from 0.34 to 0.77 kg N ha(-1) day(-1). Split applications of cattle slurry had a significant positive effect on the DM yield in two out of five experiments compared to the conventional non-split application, but only when the post-emergence slurry application was banded which is no longer in accordance with present legislation. Split applications of mineral fertilizer-N had a significant positive effect in one experiment where rainfall was excessive but not in the others. The results provide insufficient. evidence to recommend farmers to split applications. Soil mineral N sampling at the 4-6 leaf stage should hence be considered a control on the appropriateness of early N applications after exceptional weather conditions rather than a routine observation on which the post-emergence N dressing is to be based in a deliberate splitting strategy. Our data suggest that the financial return of a 40 kg ha(-1) supplementation with mineral fertilizer-N, was questionable when more than 175 kg N ha(-1) were found in the upper 0.6 m soil layer at the 4-6 leaf stage.

CC: J500 AB: Using a forced-draft chamber technique, the suppression of NH3 volatilization losses by applying N-(n-butyl) thiophosphoric triamide (NBPT) was studied in an alkaline sandy loam soil amended with green manure or wheat straw. Applied urea was completely hydrolysed in 12.8 and 6 days in unamended, green manure and wheat straw amended soil respectively. By applying 0.5% (w/w of urea) NBPT, complete hydrolysis of urea was delayed up to 16 days in the unamended soil, whereas in wheat straw amended soil urea hydrolysis was completed by the 12th day even when it was treated with 2% NBPT. Applied at 1 or 2% level, NBPT delayed the NH3 volatilization to the 4th day after application of urea in green manure or wheat straw amended soil. Hydrolysis of urea was more effectively retarded by applying NBPT in the unamended soil than in soil amended with green manure or wheat straw. In the unamended soil, 7.1% of the applied urea was lost through NH3 volatilization. The losses were reduced to 1.2 and 0.7% by applying 0.5 and 1% NBPT, respectively. Enhanced NH3 volatilization caused by the green manure or wheat straw was counteracted by applying NBPT. XAU: Punjab Agricultural University, Ludhiana, India.

CC: F600; F200 AB: Glutathione S-transferases (GSTs) are involved in detoxification of a wide variety of electrophilic compounds including herbicides. Several corn isoforms (GSTs) have been studied for their ability to conjugate these substrates with reduced glutathione (GSH). Three cDNAs, encoding corn GST subunits of 29, 27, and 26 kDa, respectively, were cloned into expression systems in Escherichia coli. N-terminal 6xHis-tagged recombinant GST isoforms I, II, III, and IV were purified with nickel-nitrilotriacetic acid (Ni-NTA) metal-affinity chromatography and were analyzed biochemically. As the corn enzymes, each recombinant GST isoform also consists of two subunits. Using three different GST-substrates, recombinant isoforms showed similar substrate specificities as natural corn GSTs. Some GST isoforms may be involved in the defense response to oxidative stress in plants. Besides standard GST activities, inactivation of endogenous, toxic alpha,beta-unsaturated aldehydes was measured. Furthermore two recombinant GST isoforms (GST II and GST IV) showed high glutathione peroxidase activity using three different organic hydroperoxides as substrates. Apparently, GST isoforms including the 27-kDa subunit show glutathione peroxidase activity. XAU: Universitat Konstanz, Konstanz, Germany.

CC: F600 AB: The aim of this study was to investigate the mechanism of photosynthetic changes in sugarcane leaves in response to chilling temperature by using three species (Saccharum sinense R. cv. Yomitanzan, Saccharum sp. cv. NiF4 and Saccharum officinarum L. cv. Badira) differing in origin and cold sensitivity. Yomitanzan is native to subtropical areas, Badira is native to tropical areas and NiF4 is a hybrid species containing genes of both tropical and sub-tropical species. At exposure to chilling temperature (10 degrees C), the photosynthetic rate in the leaves at either 10 degrees C or 30 degrees C showed a greater decrease in Badira than in NiF4 and Yomitanzan. After 28 h exposure of plants to the chilling temperature, the extractable activities of pyruvate, orthophosphate dikinase (PPDK) and NADP-malate dehydrogenase (NADP-MDH) increased or were relatively stable in the leaves of NiF4 and Yomitanzan, but decreased substantially in Badira. Correspondingly, there was a substantial accumulation of aspartate, and the level of alanine increased in Badira leaves during the chilling treatment. It is suggested that NADP-MDH and PPDK are key enzymes which may determine the cold sensitivity in photosynthesis of sugarcane. XAU: University of Nebraska, Lincoln, NE.

CC: F600 AB: High temperatures during reproductive development alter kernel development and reduce yield and quality in wheat (Triticum aestivum L.). Understanding how temperature alters kernel formation will help the development of genetic approaches to enhance heat tolerance in this cereal. A relationship between kernel development and postanthesis cytokinin accumulation is well documented, but the effect of temperature on this relationship is not known. This study quantified the effects of a postanthesis temperature treatment (7 d at 35/25 degrees C day/night) on kernel development and cytokinin accumulation in a soft white winter wheat (c.v. Stephens). Kernels from control plants maintained at 25/15 degrees C accumulated zeatin, dihydrozeatin and their corresponding 9-ribosides from 1 to 4 d postanthesis. Postanthesis kernel cytokinin accumulation was reduced by 50-80% by the temperature treatment. Kernel cytokinin content in control plants declined to baseline by 5 d postanthesis and remained at that level. Kernels from treated plants had a secondary peak of cytokinin accumulation 6-8 d after anthesis. This treatment significantly reduced kernel weight. The magnitude of the effect on kernel number was smaller than on kernel weight, but was statistically significant. Reduced kernel weight was accompanied by reduced cytokinin accumulation. Exogenous cytokinins did not mitigate the temperature effects on kernel weight, but at the highest concentrations, did reduce the effect on kernel number. XAU: USDA, ARS, Corvallis, OR.

CC: F700; F200; F400 AB: DNA sequences of the chloroplast gene ndhF were used to estimate the phylogeny of the grass tribe Andropogoneae. Previous hypotheses of relationships in the tribe were based on cytological and morphological characters such as the presence/absence of awns, monoecy vs. andromonoecy, or inflorescence characteristics. Classifications were subsequently proposed based on those ideas of relationships, and these are examined in the context of the molecular data. The notion that the base number of the tribe is x=5 is tested using the phylogeny. Diploids with n=5 are not conclusively the earliest diverging members of the group, but are nested high in the tree and the earliest diverging lineages in the tribe have n=10. Subtribal designations are not informative due to the lack of resolution between clades in the strict consensus tree. There are well-supported clades in the tribe, including three Sorghum lineages and a "core" Andropogoneae clade, even though relationships among clades are poorly supported. The topological pattern suggests a rapid radiation for the group. A preliminary assessment of the generic limits of the genus Sorghum show it to be paraphyletic, including the genera Cleistachne, Miscanthus, and a species of Microstegium. Subtribe Sorghinae is represented here by Sorghum, Sorghastrum, Cleistachne, Bothriochloa, Capillipedium, Dichanthium, and Chrysopogon and does not form a monophyletic group.

The effect of these extrusion variables on the pasting behaviour of extruded products was studied, using a rapid visco analyser (RVA). The viscosity-related parameters determined include initial peak viscosity, cold paste viscosity and breakdown viscosity. Moisture content of the feed had a dominating effect compared to that of the screw speed of the extruder; an increase in moisture increased the aforesaid viscosity-related parameters. High moisture content of the blend changed the pasting characteristics of the extruded material to a great extent when the screw speed was between 200 and 300 rpm. The net specific mechanical energy was negatively related (p < or = to 0.05) to the viscosity-related parameters. XAU: Central Food Technological Research Institute, Mysore, India.

CC: J500; F600; F120; F110 AB: Seed yield response of cool-season grasses to spring-applied N is usually limited because of lodging. This study investigated whether chemical dwarfing of these crops improves their seed yield response to spring-applied N. Chewing's fescue [Festuca rubra L. subsp. fallax (Thuill.) Nyman; syn. F. rubra var. commutata Gaudin], tall fescue (Festuca arundinacea Schreb.), and orchardgrass (Dactylis glomerata L.) were established in September 1983 near Corvallis, OR. Treatments were all combinations of 90, 120, 150, 180, and 210 kg N ha(-1) applied at the double-ridge stage of development, followed by paclobutrazol [(2RS,3RS)-1-(4-chlorophenyl)-4,4- dimethyl-2-(1H-1,2,4- triazol-1-yl)-pentan-3-ol] at 0, 0.25, 0.5, and 1 kg a.i. ha(-1) applied at floret initiation stage in 1985 and 1986. Averaged across years and N rates, the 1 kg ha(-1) rate reduced Chewing's fescue height by 23% and tall fescue and orchardgrass heights by 30%. In the absence of paclobutrazol, Chewing's fescue and tall fescue seed yields were the greatest at 90 kg N ha(-1). Paclobutrazol did not affect seed yield response of Chewing's fescue to N rates, but tall fescue seed yield in 1986 was the greatest at 150 kg N ha(-1) when only 0.25 kg a.i. paclobutrazol ha(-1) was applied. Averaged across N rates, the 0.5 kg ha(-1) rate increased Chewing's fescue seed yield by 32% in 1985 and 18% in 1986, and also increased tall fescue seed yield by 32% in 1985 and 23% in 1986. Orchardgrass seed yield was the greatest at 180 kg N ha(-1) in both years. Paclobutrazol did not affect orchardgrass seed yield in 1985, and the 1 kg ha(-1) rate decreased seed yield in 1986. We concluded that in western Oregon paclobutrazol. application at floret initiation does not improve seed yield response of these crops to spring-applied N, but it would significantly improve Chewing's fescue and all fescue seed yield, regardless of the N rate applied. Results did not indicate any advantage for applying paclobutrazol on orchardgrass seed crop. XAU: Oregon State Univ., Corvallis, OR.

CC: J500; F600; F120; F110 AB: Understanding effects of spring N rates and application timing on seed yield and yield components of cool-season grass seed crops will help improve N fertilization management. We tested effects of 90, 120, 150, 180, and 210 kg N ha(-1), applied at the double-ridge (DR) stage of development on seed yield and yield components of Chewing's fescue [Festuca rubra L. subsp. fallax (Thuill.) Nyman; syn. F. rubra var. commutata Gaudin], tall fescue (F. arundinacea Schreb.), and orchardgrass (Dactylis glomerata L.) in 1985 and 1986. In a second study, effects of 120 kg N ha(-1), applied either at DR, at spikelet initiation (SI), or equally split between the two stages, were tested. Soil type for both experiments was fine-silty, mixed, mesic Aquultic Argixerolls. Chewing's fescue seed yield was not affected by N rates in 1985 and was the greatest at 90 kg N ha(-1) in 1986. Averaged across years, orchardgrass seed yield was the greatest at 120 kg N ha(-1). Nitrogen rates did not affect seed yield of tall fescue. Seed yield of all species was most closely correlated with the number of seeds produced per unit area. Seed number per unit area was primarily correlated with the number of seeds produced per panicle in all species; in orchardgrass, the number of panicles per unit area also contributed to total number of seeds produced. Seed yields of all three species were the greatest when N was applied at DR. Split application was not better than application of all N at DR or SI. We concluded that in western Oregon spring application of 90 kg N ha(-1) for Chewing's fescue and tall fescue and 120 kg N ha(-1) for orchardgrass should be adequate for seed production. For all species, spring N should be applied in one. application at DR. XAU: Oregon State Univ., Corvallis, OR.

CC: F600 AB: Seed size has been associated with early seedling vigor (i.e., germination rate, emergence rate, and growth) in grasses. This study was conducted to compare seedling development over a 60-d period in the field as affected by heavy seed (HS) (0.19 to 0.21 g 100 seed(-1)) and light seed (LS) (0.13 to 0.16 g 100 seed(-1)) of 'Blackwell' and 'Trailblazer' switchgrass (Panicum virgatum L.). The experiment was conducted in 1995 and 1996 at Lincoln, NE, on a Kennebec silt loam (fine-silty, mixed, superactive, mesic Cumulic Hapludolls). The experimental design was a randomized complete block with four replicates. Seed was separated into two sizes using a South Dakota seed blower. Seed was planted into rows at a rate of 100 pure live seed per meter of row. Plants were excavated and evaluated for shoot weight, leaf area, and root weight. Shoot and root systems were morphologically staged four times during the summer. Seed size differences in switchgrass appeared to produce only slight differences in morphological development of shoot and root systems, leaf area, shoot weight, and adventitious root weight from seedling emergence to 6 wk of growth. Adventitious roots formed more quickly on seedlings from heavier than lighter seed, but the advantage to seedling establishment was minimal even when soil moisture appeared to be lacking. By 8 to 10 wk after emergence, growth and development of LS seedlings were similar to HS seedlings. Once seedlings formed two or more adventitious roots, seed size no longer affected establishment and growth. Seed size in switchgrass appears to have a minimal long-term effect on growth and development of seedlings. XAU: Univ. of Nebraska-Lincoln, Lincoln, NE.

CC: F500; J700; F120 AB: A critical evaluation of legumes should consider both the above-and belowground contribution to N(2) fixation. Based on the amount of N in crops and correcting for the changes of soil N as a result of cropping, 15 equations are presented for estimation of the apparent net amount of atmospheric N(2) fixed by legumes grown in short- and long-term cropping systems. In the final equation, all components of a legume-cereal rotation system were considered. In estimating N(2) fixation, including in the equation the non-N(2)-fixing crop that follows the legume in the rotation is an innovation of the method, in addition to the system approach concept. The validity and accuracy of each equation in estimating N(2) fixation by legumes is discussed. An example is provided using data from long-term vetch-barley (Vicia sativa L.-Hordeum vulgare L.) rotation studies in Cyprus. The estimated amount of apparent net N(2) fixation by vetch was 184 kg N ha(-1), a quantity twice that usually estimated using only the aboveground vetch production. This result shows the importance of calculating apparent net N(2) fixation by considering above- and belowground system components. XAU: Agricultural Research Institute, Nicosia, Cyprus.

CC: F600; F200; J700 AB: Oat (Avena sativa L.) intercropped with berseem clover (Trifolium alexandrinum L.), an annual forage legume, has economic and biological advantages for use as a rotation crop in the north-central USA. To investigate the effects of different oat and berseem clover cultivars on the productivity of the intercrop and its components, and to test for interspecific cultivar interactions, we evaluated binary combinations and monocultures of a sample of oat and berseem clover cultivars in three Iowa environments. Oat cultivars varied for oat traits, effects on clover stands and yield, and total intercrop biomass. Berseem clover cultivars varied for forage yield, stand, maturity, damage due to disease and insects, and effects on intercrop biomass. In one environment, only one of seven berseem clover cultivars survived after the first forage harvest. Adding oat to berseem clover reduced total forage and weed yields, clover stands, and relative maturity of clover, but increased total crop biomass and forage plant health. Adding berseem clover to oat did not reduce oat grain or straw yields, and in one year increased oat test weight. Cultivar rankings of each species differed in monoculture vs. intercrop. Interspecific cultivar interactions were not significant for most traits. Greater genetic improvement in the productivity of the oat-berseem clover intercrop will more likely be achieved by improvement of general agronomic productivity of berseem clover than by trying to enhance specific ecological combining ability of particular oat and berseem clover cultivar combinations.

CC: F600 AB: In Mediterranean environments, translocation of pre-anthesis assimilates to the grain is an important source of photosynthates. In this work, the effect of forage removal at the beginning of jointing on the amount of dry matter (DM) accumulated before anthesis and remobilized during grain filling was studied in five spring and five winter triticale genotypes (x Triticosecale Wittmack). Field experiments were conducted in 1992 and 1993 in northeastern Spain. Two harvesting treatments were used: (i) grain production only and (ii) cutting the crop for forage at the beginning of jointing and harvesting the grain produced after regrowth. Pre-anthesis storage of carbohydrates was very important to grain filling in triticale, both for grain and for dual-purpose. Contribution of pre-anthesis assimilates to grain yield in the uncut plots was 46% in spring triticale genotypes and 65% in winter genotypes, as the later-maturity winter triticale genotypes were more affected by terminal abiotic stresses. Reductions in DM accumulated at anthesis after forage removal were more pronounced in winter genotypes (39%) than in spring genotypes (20%), where an earlier development allowed for a longer recovery period after cutting; DM reductions were similar to grain yield decreases. The effect of forage removal on translocation depended on the growth habit of the genotype and environmental conditions. Most differences were associated with changes in crop phenology. In spring types, with early jointing, DM translocation and the contribution of pre-anthesis assimilates to grain were not affected by forage removal, whereas both traits were drastically reduced in winter triticale. Most differences in (13)C/(12)C carbon. isotope discrimination (delta) in grains were also phenology driven. XAU: IRTA, Lleida, Spain.

CC: F600; F200 AB: Little is known about the pattern of growth and biomass partitioning of spring and winter triticale (X Triticosecale Wittmack), although such information can aid in interpreting the results of field experiments and is an essential step in the development of crop simulation models. This study was conducted to analyze and compare the growth of five winter and five spring triticale genotypes over two years in northeast Spain. Plants were sampled at the main stages of the Zadoks scale, and biomass, LAI and their components, and stem elongation were determined. The relationships between all the growth traits studied and accumulated growing degree-days from sowing (GDD) were described by the same asymmetric logistic peak curve. Genotypic variability could be mainly associated with plant phenology. On average, winter triticale types needed 165 more GDD than spring types to reach maximum LAI. Also, winter triticale genotypes needed 109 more GDD to complete their main stem elongation, and 109 more GDD to reach their maximum rate of dry weight accumulation in the stems than spring genotypes did. The length of the first tiller was closer to the length of the main stem in winter types than in spring types. Both types of triticale had similar patterns of biomass accumulation. The asymmetric logistic peak curve used in this work fitted asymptotic and peak-type relationships, and can be a useful tool for growth studies. XAU: IRTA, Lleida, Spain.

CC: J700; J200; F120 AB: Because of their deep roots and high water demand, alfalfa (Medicago sativa L.) hay crops can reduce water available to crops following in the rotation. Recharging the soil water profile after alfalfa is, therefore, a high priority in dryland cropping systems. The objective of this study was to investigate effects of alfalfa crop termination date (late June, early August, and in spring immediately before spring wheat seeding) and method (herbicides, tillage, and herbicides plus tillage) on soil water conservation, and establishment, yield, and water use efficiency (WUE) of a following spring wheat (Triticum aestivum L.) crop. Experiments were conducted over 5 site-years in a subhumid region of western Canada. Herbicide termination resulted in greater total water recharge and a faster rate of water recharge than treatments involving tillage. Greater efficiency of soil water recharge for herbicide termination after the first hay harvest (late June) appeared to cause deep water percolation at one site. Delaying termination until after the second hay harvest (early August) did not reduce soil water availability at spring seeding of the following wheat crop, but increased reliance on overwinter soil water recharge. Delaying herbicide treatment until spring reduced water at seeding and wheat yields in some cases. Compared with treatments involving tillage, herbicide treatments resulted in higher levels of groundcover (i.e., greater soil erosion control), higher WUE, and higher grain yields. Herbicide termination after the second hay harvest produced the most favorable overall outcome; better than the traditional approach of tillage after the first hay harvest.

ID: urea-dicyandiamide. CC: F500; J500; F600 AB: Hydroponic and greenhouse studies have shown that grain yields of wheat (Triticum aestivum L.) are maximized when the N supply contains a mixture of NH(4) and NO(3). Tillers per plant is the yield component most commonly increased by mixed N nutrition in greenhouse studies. The objective of this study was to evaluate, under field conditions, the response of 'Butte 86' spring wheat to N sources differing greatly in nitrification rate. Nitrogen was applied at 0 or 112 kg N ha(-1); the N sources were calcium nitrate (CN), urea, urea-dicyandiamide (DCD), 0.1-g urea granules, and 0.1-g urea-DCD granules. Six field trials were performed. Topsoil (0-15 cm) analysis of fertilized plots during tillering indicated a wide range of mineral N contents (19-101 mg N kg(-1) and of NH(4):NO(3) mole ratios (0.04-2.06). Correlation analyses suggested that tillering was sensitive to the total mineral N supply, but quite insensitive to the NH(4); NO(3) ratio in the topsoil. Vegetative growth and N uptake were generally lower for CN than for the other N sources. At some locations, more heads per square meter at harvest were observed with the slower-nitrifying N sources. Grain yields were increased by N fertilization, but significant differences between N sources were not generally observed. For both years of the study, the 0.1-g urea-DCD granules gave the highest N uptake efficiency. However, the dramatic responses in growth, tillering, or grain yield routinely observed with mixed N nutrition in hydroponic or greenhouse studies could not be duplicated in the field.

CC: J500; F120; J200; F600 AB: Intensive land use in the Rolling Pampa of Argentina appears to be reducing soil quality for crop production. Our objective was to establish the best edaphic and/or plant indicators for assessing soil quality with regard to functioning as a medium for crop production. Nine fields with Typic Argiudoll soils were selected for evaluation based on agriculture history and apparent soil structural stability. Soil chemical and physical properties and maize (Zea mays L.) vegetative and reproductive characteristics were measured. Multivariate statistical analyses were applied to the data to determine potential indicators of soil quality. Soil and crop variables explained more than 70% of the variance in soil quality among agricultural histories. The edaphic indicators that showed the greatest change from pristine conditions were organic C, total N, P, Mg, K, B, Ca, and Zn contents and cation exchange capacity. Using crop variables, leaf length, maximum fraction of intercepted photosynthetically active radiation, grain yield, kernel number, prolificacy, and total dry matter at physiological maturity, served to establish a soil quality gradient. Variation of maize growth was associated with edaphic indicators of soil quality and revealed the importance of soil aggregate stability in determine changes in soil quality for crop production.

CC: F120; F600; J200 AB: Crop productivity under dryland conditions is largely limited by soil water availability. Soil organic matter (SOM) contents have been found to be a reliable index of crop productivity in semiarid regions because it positively affects soil water-holding capacity. Our objectives were to explain differences in wheat (Triticum aestivum L.) yields in response to SOM levels and related properties and to quantify the contribution of a unit increment of SOM content to soil productivity during 1991, 1992, and 1994 on a total of 134 production fields in the semiarid Argentine Pampas. Wheat yields were related to both soil water retention and total organic C (TOC) contents in the top layers 0-20 cm) in years with low moisture availability (1992 [r = 0.51, P < 0.01] and 1994 [r = 0.59, P < 0.01]), and were related to both total N and available P contents in a year without water deficit stress (1991 [r = 0.58, P < 0.01). Wheat yields over all years were linearly related to TOC (r = 0.68, P < 0.01) when these contents were <17.5 g kg(-1). Dependence of wheat yields on soil water retention and on TOC contents under water deficit was related to the positive effect of these soil components on plant-available water. In the absence of water deficit (1991), nutrient availability was the limiting factor. Losses of 1 Mg SOM ha(-1) were associated with a decrease in wheat yield of approximately 40 kg ha(-1). These results demonstrate the importance of using cultural practices that minimize losses of soil organic C in the semiarid Argentine Pampas. XAU: Univ. of Kentucky, Lexington, KY.

CC: F600; X100 AB: Daily crop water uptake was simulated using algorithms from three crop simulation models, CropSyst, CERES, and EPIC (listed in order of decreasing process detail). Simulated results were compared with measurements of sap flow and soil water content for maize (Zea mays L.) growing at Prosser, WA, under a wet and a dry irrigation treatment, and with soil water content measurements for nonirrigated maize at Davis, CA. At Prosser, the dry treatment imposed only a mild stress; at Davis, the stress was severe. Simulation variables such as maximum crop evapotranspiration, root density by soil layer, and green leaf area index were provided as daily input. At Prosser, all algorithms performed similarly when simulating crop water uptake. For the wet treatment, the root mean square error (RMSE) was 0.27 to 0.28 mm d(-1) , and the relative error [RE = 100 (RMSE/Measured average) was 7.0 to 7.2%. For the dry treatment, simulation accuracy decreased (RMSE = 0.33-0.38 mm d(-1); RE = 9.0-10.5%). The time evolution of water uptake simulated by CropSyst better depicted the measured sap flow (water uptake) difference between wet and dry treatments. Simulations of soil water content by layer for the wet treatment, compared with measurements available for 17 d, yielded RMSEs from 0.022 to 0.024 m(3) m(-3) and REs from 8.5 to 9.2%. For the dry treatment (12 d of measurements), the best simulations were obtained with the water uptake algorithms from CropSyst and CERES, with RMSE = 0.015 m(3) m(3) (both models) and RE = 6.4% (CropSyst) and 6.6% (CERES), compared with RMSE=0.019 m(3) m(-3) and RE = 8.1% for EPIC. Under the severe water stress at Davis, CropSyst had the best performance. This algorithm simulated changes in soil water content by layer (8 d of measurements available) with RMSE of 0.011 m3 m-3 and RE of 5.0%, while the RMSE and RE values for CERES and EPIC were 0.016 and 0.019 m(3) m(-3) and 7.6 and 9.0%, respectively. The more process-oriented algorithm (CropSyst) showed an increasing advantage as water stress severity increased. The EPIC algorithm had the poorest performance under water stress. This could be improved by modifying the value of the water extraction distribution parameter in EPIC, but with this change the wet treatment simulations at Prosser deteriorated substantially, indicative of limitations in EPIC's simple approach.

CC: F600; X100; W000; B200 AB: Dynamic crop-growth models are used to project the effects of rising atmospheric CO(2) concentration and associated climate change on crop yields. Such model predictions are largely untested in the field, for lack of experimental data. We tested the CERES -Wheat model, modified to include leaf-level photosynthesis response to elevated CO(2), using field data from 2 yr of Free-Air Carbon Dioxide Enrichment (FACE) experiments with spring wheat (Triticum aestivum L. cv. Yecora Rojo) in Maricopa, AZ. Two irrigation treatments (well-watered, WW; water-deficit stressed, WS) and two atmospheric CO(2) concentrations (ambient, 350 micromole mol(-1); elevated, 550 micromole mol(-1) were simulated. The model was evaluated using measurements of crop phenology, aboveground dry matter (DM) production, grain yield, and evapotranspiration (ET). Model calculations of crop phenology were within 2 to 3 d of observed values under WW, ambient CO(2) conditions in both years. The model did not simulate the accelerated crop phenology (5-8 d at physiological maturity) observed in the WW and elevated CO(2) treatments, indicating the need to include effects of increased stomatal resistance on canopy temperature. Simulations of DM and grain yield were within 10% of measured values, except for a tendency to overcalculate DM response to CO(2) by 10 to 15% in Year 1 for WS treatments. The model undercalculated cumulative ET under WW conditions by 15%; model sensitivity analyses suggest that simulation of potential evapotranspiration (PET) was too low for this arid site. The model reproduced measured dynamics of CO2-water interactions. Simulated reductions in water loss due to elevated CO2. were about 4%, in agreement with measurements. The model simulated larger increases in DM production and yield due to elevated CO2 under WS than under WW conditions. In Year 1, simulated crop response to CO2 was 2% larger (measured: 3%) under WS than under WW conditions; in Year 2, it was 11% larger (measured: 9%). The ability to simulate CO2-water interactions, though it needs to be further evaluated with additional experimental datasets, is an important attribute of models used to project crop yields under elevated CO2 and climate change.

CC: J200; X100; F600; W000; X200; F120 AB: The Ohio Management Systems Evaluation Areas (MSEA) project focused on developing and evaluating improved agricultural management systems and predictive models. The Root Zone Water Quality Model (RZWQM) is an environmental model for simulating water, chemical, and biological response of agricultural management systems. This paper presents calibration and evaluation of the generic plant productions model of RZWQM, as well as some evaluation results for the nitrate and soil water content predictions. Corn (Zea mays L.) and soy bean (Glycine max (L.) Merr.] biomass data collected at the Ohio MSEA from 1991 to 1993 were used for evaluation. Data from 1992 were used in calibrating RZWQM, and data from two other years (1991 and 1993) at the same site were used for validation. Crop growth predictions were compared with observed values of leaf, stem, and seed biomass collected throughout the growing season. Leaf and stem biomass predictions generally fell within 1 SD of the observed values, but for all years there were dates when predictions were outside of the observed range. RZWQM predicted seed biomass or yield adequately for all 3 years with predictions falling within 1 SD of the observed values. Soil water content estimates for corn were higher than observed values late in the season, perhaps because of underestimates if evapotranspiration due to errors in leaf area predictions. The model overpredicted nitrate concentrations for the corn plot late in the season. Nitrate concentrations for the soybean plot were generally underpredicted. These differences may be due to underestimates of the fast humus pool of the nutrient model and of the N(2) fixation rate for. soybean. More evaluation is needed to refine the nitrate and soil water content predictions. XAU: Ohio State Univ., Columbus, OH.

CC: J200; X100; F120; W000; X200 AB: Evaluation of agricultural simulation models against field observations is needed to gauge their usefulness. This study was conducted to assess the ability of the Root Zone Water Quality Model (RZWQM) to simulate dryland and irrigated corn (Zea mays L.) production systems in semiarid eastern Colorado. The model was first parameterized for corn using field data from a single season. Different parameters were identified for irrigated and dry land corn. The parameterized model was run on independent data sets from the following year (irrigated) and different soils and sites (dryland) and model results were compared with field measurements. Differences between modeled and measured components of soil water content, evapotranspiration, grain yield and biomass, and crop N uptake ranged from 1 to 23% in the dryland study and from 1 to 28% in the irrigated study. On a seasonal basis, model estimates of seepage below the root zone were within 3% of measured values, while NO(3)-N leaching was overpredicted by 79%. Note that model parameterization relied solely on single-season data. This could potentially produce bias in parameter values due to the narrowness of the prevailing conditions during that single season. For this reason and for the purpose of using the model to assess the long-term impact of alternative practices, further work on parameterization and evaluation of the model needs to focus on using experimental observations from multiple seasons.

CC: J200; X100; J500; F120; W000; X200 AB: The Root Zone Water Quality Model (RZWQM) was evaluated for a region that has a long history of irrigated corn (Zea mays L.). Imprecise irrigation and plentiful fertilizer applications have contributed to the buildup of NO(3)-N in ground water, where concentrations often exceed 30 mg L(-1). Experiments were conducted to evaluate the effects of management practices on corn yield, N uptake, plant biomass, leaf area development, soil water content, and soil N. Field-measured results from 1992 were used to calibrate RZWQM. The model was evaluated by simulating three irrigation levels and five fertilizer rates for 1993 and 1994. The model simulated the soil water pattern satisfactorily during most of the growing season; however, the simulated soil profile water content was lower than field conditions in the spring and fall. Transpiration appears to be excessive when the leaf area index (LAI) is small. Simulated yields exceeded measured values, with the largest errors for small fertilizer applications in 1993 and for large fertilizer applications in 1994. The mean error between measured and modeled yields was 2.9 Mg ha(-1), with a root mean square error (RMSE) equal to 46% of the mean yield for all treatments over the 3 years. Estimates of LAI and aboveground biomass were closer to measured values, with mean errors of 5% for leaf area and 1% for biomass. The relative RMSE for LAI and biomass was 26 and 17% respectively. The model underestimated aboveground N uptake, with a mean error of 25 kg N ha(-1) and a relative RMSE of 41% while development of the comprehensive RZWQM has been constructive, improvements are still needed. Excessive depletions in the spring and fall. overstate storage of off-season precipitation, and this leads to underestimating annual leaching losses. Combining excessive yield predictions with low N uptake estimates exaggerates the N use efficiency. These discrepancies will have a profound effect on the simulated impact of management practices. Leaching losses and yield effects will be understated, which may lead to development of policies that affect producers more severely than the model implies. XAU: Univ. of Nebraska, Lincoln, NE.

CC: J200; X100; W000; J500; H000; X200 AB: Before simulation models can be used to evaluate the benefits of alternative management systems, their accuracy needs to be examined. This study evaluated the performance of the Root Zone Water Quality Model (RZWQM Version 3.2) against crop yield and water, nitrate and herbicide fate and transport during four years of a corn-soybean [Zea mays L.-Glycine max (L.) Merr.] rotation. The model was calibrated and initialized using default values supplied with the model and adjusting model parameters to obtain stable organic matter and microorganism pools. The model was further calibrated to match crop yields for the first two years of measurements. For the second two years, predicted soybean yield was within 60 kg ha(-1) (3%) of measured yield but predicted corn yield was underpredicted by 790 kg ha(-1) (10%). Disagreements between modeled and measured yields may be due to factors not included in the model such as disease and insect damage. The model estimated total soil nitrate content well, although nitritication rates during winter were overestimated. Predicted nitrate leaching out of the root zone agreed well with measured losses to tile drainage. Predictions of herbicide residues with the one-parameter lumped dissipation model option were best after reducing the expected half-lives of metribuzin [4-amino-6-(1,1-dimethylethyl)-3- (methylthio)-1,2, 4-triazin-5(4H)-one], or atrazine [6-chloro-N-ethyl-N'-(1-methylethyl)-1,3, 5-triazine-2,4-diamine], by a factor of four. The two-parameter lumped half-life model option improved the prediction for atrazine but not for metribuzin. Predictions of herbicide losses in drainage water were overestimated in the second year following herbicide. application. Neither nitrate nor herbicide concentrations in the soil profile were modeled satisfactorily. Invoking the macropore option of the model did not consistently improve model prediction of a herbicide leaching. Overall, the model shows promise in predicting the interplay of climate, soil, and management on crop yield and nitrate fate, but evaluation over a wide range of conditions is needed.

CC: J200; X100; W000; H000; X200 AB: The USDA-ARS Root Zone Water Quality Model (RZWQM) is a comprehensive computer model developed to simulate water, chemical, and biological processes in the root zone of agricultural management systems. The model is capable of evaluating the effects of various cropping and management practices on surface and ground water quality. In this study, the performance of RZWQM Version 3.2 was evaluated for a claypan soil, particularly surface runoff and chemical loss to surface runoff predictions. The model was calibrated and evaluated using data collected from the Missouri Management Systems Evaluation Area (MSEA) and the Kingdom City runoff plots. Soil water predictions of the model compared well with those measured, particularly at the 15-, 60-, 75-, and 90-cm soil depths. In most cases corn (Zea mays L.) and soybean Glycine max (L.) Merr.] yield predictions were within 15% and 20%, respectively, of those measured. Using the macropore option (constant cracking) greatly improved the prediction of chemical losses to seepage. Annual runoff simulated for corn and soybean under conventional and no-till systems was adequately predicted. The model underpredicted large runoff events and overpredicted runoff events that occurred after long dry periods when soil cracking was a dominant factor. The model overpredicted NO-(-3)-N concentrations in runoff but underpredicted concentrations in near-surface soils. Predicted and measured atrazine [6-chloro-N-ethyl-N'-(1-methylethyl)-1,3,5-triazine-2, 4-diamine] and alachlor [2-chloro-N-(2,6-diethylphenyl)-N-(methoxymethyl) acetamide) concentrations in surface runoff compared well, particularly when the computed runoff was closed to that measured. In this study, the model. was run using the option of constant cracking in the soil. To improve the predictions of agrichemical losses to runoff and seepage, RZWQM should include the capability to predict variable soil cracking based on soil moisture.

Field soil water contents, intensively measured by time-domain reflectometry (TDR) on a Zimmerman fine sand soil (Argic Udipsamments) in the Minnesota Management Systems Evaluation Area (MSEA), were used to evaluate the Root Zone Water Quality Model (RZWQM) over two rotated crop growing seasons in 1992 (corn, Zea mays L.) and 1993 [soybean, Glycine max (L.) Merr.]. The model was evaluated based on laboratory-measured soil hydraulic properties. Reasonable agreement exists between the daily TDR measured and RZWQM-predicted water contents for the upper soil depths. However, the model overestimated the lower soil profile, leading to a consistent overestimation of the total water depth (TWD) in the entire root zone (0 to 150 cm) during both the 1992 and 1993 growing seasons. The maximum errors in TWD for the entire root zone were 2.47 and 2.77 cm, respectively in 1992 and 1993. Predictions of solute transport by RZWQM were examined for three herbicides: atrazine [6-chloro-N-ethy-N'- (1-methylethyl)-1,3,5-triazine-2,4- diamine], alachlor [2-chloro-N-(2,6- diethylphenyl)-N- (methoxymethyl)acetamide], and metribuzin [4-amino-6-(1,1-dimethylethyl)-3- (methylthio)-1,2,4-triazin-5(4H)-one]. Comparison between measured and predicted soil herbicide concentrations averaged over the top 15-cm layer showed that the model matched the temporal changes of the field measurements reasonably well, although the measurements showed that all pesticides were somewhat more persistent over time than the model predicted.

CC: J100; J500; W000 AB: Potato fields and cut (ungrazed) grassland in SE Scotland gave greater annual N2O emissions per ha (1.0-3.2 kg N2O-N ha-1) than spring barley or winter wheat fields (0.3-0.8 kg N2O-N ha-1), but in terms of emission per unit of N applied the order was potatoes > barley > grass > wheat. On the arable land, especially the potato fields, a large part of the emissions occurred after harvest. When the grassland data were combined with those for 2 years' earlier work at the same site, the mean emission over 3 years, for fertilization with ammonium nitrate, was 2.24 kg N2O-N ha-1 (0.62% of the N applied). Also, a very strong relationship between N2O emission and soil nitrate content was found for the grassland, provided the water-filled pore space was > 70%. Significant relationships were also found between the emissions from potato fields and the soil mineral N content, with the added feature that the emission per unit of soil mineral N was an order of magnitude larger after harvest than before, possibly due to the effect of labile organic residues on denitrification. Generally the emissions measured were lower, as a function of the N applied, than those used as the basis for the current value adopted by IPCC, possibly because spring/early summer temperatures in SE Scotland are lower than those where the other data were obtained. The role of other factors contributing to emissions, e.g. winter freeze-thaw events and green manure inputs, are discussed, together with the possible implications of future increases in nitrogen fertilizer use in the tropics.

CC: L600; L500 AB: Hereford X Angus steers were used in a 13-treatment, four-period, incomplete Latin square design to examine the effects of starch and degradable intake protein (DIP) supplements on forage utilization and ruminal function. Steers were given ad libitum access to low-quality hay (4.9% CP) and were not supplemented (NS) or received different amounts of starch (cornstarch grits; 0, .15, and .3% of initial BW) and DIP (Na-caseinate; .03, .06, .09, and .12% of initial BW) administered via ruminal fistulae in a 3 X 4 factorial arrangement of treatments. Supplemented steers consumed more (P < .01) forage OM, total OM, NDF, and digestible OM (DOM) than NS steers. Forage OM, total OM, NDF, and DOM intakes increased linearly (P < .01) as the amount of supplemental DIP increased. The addition of starch to supplements linearly decreased (P < .01) the intake of forage OM, NDF, and DOM. The digestion of DM, OM, and NDF increased linearly (P < .01) with supplemental DIP and decreased linearly (P less than or equal to .06) with supplemental starch. Particulate and liquid passages generally increased with DIP; however, starch level influenced the nature of the response (P = .03 and .06, respectively). Similarly, ruminal acid detergent-insoluble ash content generally decreased as starch increased, but the effect was dependent on DIP level (P < .01). Supplementation increased (P < .01) ruminal NH3 and total VFA and decreased (P < .01) ruminal pH relative to NS. All treatments supported average pH values in a range (6.3 to 6.7) unlikely to inhibit fibrolytic bacteria. Ruminal NH3 concentration increased quadratically (P = .03) with DIP and decreased linearly (P = .02) with starch. As. DIP increased, total VFA concentration increased linearly (P = .02). Providing supplemental DIP to steers fed low-quality forage increased OM intake and digestion, whereas addition of atarch to supplemental decreased forage intake and digestion.

CC: L500; L600 AB: Six Angus steers (260 +/- 4 kg initial BW) fitted with ruminal, duodenal, and ileal cannulas were used in a 6 X 6 Latin square design to evaluate the effect of feeding poultry by-product meal (PBM) on small intestinal flow and disappearance of amino acids. The diets were provided at 2% of BW on a DM basis, formulated to contain 11.5% CP, and consisted of 49% corn silage, 36% cottonseed hulls, and 15% supplement on a DM basis. Supplements were formulated to contain 37% CP with sources of supplemental N being soybean meal (100% SBM) and 0, 25, 50, 75, and 100% PBM, with urea used to balance for N. Duodenal flow of all amino acids increased linearly (P < .07) as PBM increased in the diet and, except for His, increased (P < .09) for 100% PBM compared with 100% SBM. Similar results were observed for duodenal flow of nonbacterial amino acids, which linearly increased (P < .05) with PBM and were greater (P < .05) for 100% PBM than for 100% SBM. Soybean meal increased (P < .09) the duodenal flow of nonbacterial Lys compared with 0% PBM, and 0% PBM increased (P < .04) flow of Val, Ala, and Pro compared with 100% SBM. Duodenal bacterial essential, nonessential, and total amino acid flows were not affected (P > .80) by PBM, however, they were greater (P < .02) for 100% SBM than for 100% PBM. In addition, nonessential and total bacterial amino acid flows were increased (P < .06) for 100% SBM compared with 0% PBM. Small intestinal disappearance of Lys and Pro increased linearly (P < .09) as PBM increased, and 100% PBM increased (P < .07) disappearance of Arg and Ala compared with 100% SBM. Supplemental N source had no effect (P > .31) on apparent small intestinal disappearance of essential, nonessential. and total amino acids. These data suggest that when PBM, SBM, and urea were used as sources of supplemental N, the daily disappearance of amino acids from the small intestine of steer calves consuming a corn silage- and cottonseed hull-based diet was similar.

CC: L500 AB: Multiparous (n = 26) and primiparous (n = 18) Holstein cows were fed prepartum and postpartum total mixed diets that were, or were not, supplemented with a yeast culture (YC) for approximately 23 d prepartum and 56 d postpartum. Multiparous cows supplemented with YC selected a prepartum diet higher in CP than did unsupplemented cows, although prepartum performance of cows of both parities, as assessed by DMI and measures of body status, was not influenced by YC. The extent of the prepartum DMI depression was not influenced by YC supplementation in cows of either parity. An intake behavior study with six multiparous cows suggested that cows supplemented with YC exhibited repeated diurnal feed intake patterns until approximately 7 d prepartum, vs 10 d prepartum for unsupplemented cows. Cows of both parities supplemented with YC had numerically higher DMI and production of milk and milk components, although only DMI for multiparous cows and milk production for primiparous cows approached statistical significance. Intake behavior results suggested that cows supplemented with YC achieved repeated diurnal feed intake patterns by approximately 14 d postpartum, vs 20 d postpartum for unsupplemented cows. Concentrations of ruminal metabolites and pH did not differ between treatments, although ruminal fluid collection occurred while diurnal feed intake patterns were repeated (regular). Overall, our results can be interpreted to support a trend toward a modest postpartum improvement in performance of primiparous and multiparous cows supplemented with this YC for 23 d prepartum and 56 d postpartum. However, primiparous cows seemed to achieve this modest overall improvement primarily through enhanced. postpartum DMI, whereas in multiparous cows it was due almost equally to enhanced postpartum DMI and higher energy density of the diet.

CC: L600 AB: Four ruminally cannulated cows were used to assess the distribution of the concentrations and carbohydrate-degrading enzyme activities of the liquid-associated protozoa (LAP) and solid-associated bacteria (SAB) in the rumen. The cows were fed diets (7 kg of DM/d) of 100% hay (Diet F) or 60% barley plus 40% hay (Diet C) in a 2 X 2 crossover experimental design. Samples of ruminal digesta were collected successively from the dorsal (DS), ventral (VS), and anterior (AS) sacs 1 h before and 3 h after the morning feeding on two sampling days with a 2-d interval. Irrespective of diet and sampling time, the greatest proportion of entodiniomorphs, representing the main population of protozoa, was found in the DS (40% mean; P < .05). Low pH values observed in the DS (P < .05) indicated higher fermentative activity in this site than in the other parts of the rumen. Protozoa may contribute more than previously thought to the high digestive potential present at the top of the rumen that has classically been attributed to bacteria. The specific activity of plant cell wall polysaccharide-degrading enzymes in the LAP was correspondingly greater (P < .05) for DS than for VS or AS. For the two diets and sampling times, specific activity of fibrolytic enzymes in the SAB tended to be less in the upper than in the lower parts of the rumen, and less in the VS than in the AS. This tendency became significant (P < .05) for total fibrolytic enzyme activity. Differences in bacterial colonization of particles among the three sampling sites may explain such differences in fibrolytic activity of the SAB. Data suggest a spatio-temporal complementary action of the bacteria and protozoa in ruminal plant cell wall degradation. at least with the barley diet, for which the number of protozoa was highest.

CC: L500; L600 AB: Efficiency of limit-feeding a whole shelled corn-based diet as an alternate to a conventional forage-based diet for nonlactating dairy cattle was determined. Twelve nonlactating, multiparous Holstein cows (initial BW 642 +/- 50 kg) were used in a randomized complete block design. Nutrient digestibility, excretion of DM, N, and P, performance of cows, and feed costs were measured. Both diets were formulated to provide equal daily intakes of NE1, protein, vitamins, and minerals, according to National Research Council recommendations. Dry matter intake was restricted by 30% for cows fed the high-corn diet compared with the high-forage diet (6.8 vs 9.6 kg/d, respectively); therefore, concentrations of nutrients in the high-corn diet were increased to compensate for decreased DMI. Diets were fed once daily, and cows had unlimited access to fresh water. After a 28-d adaptation period, cows were placed in metabolism stalls for a 6-d total collection of feces and urine. The limit-fed, high-corn diet had a 15% greater DM digestibility than the high-forage diet. A 29% decrease in DMI for the high-corn diet vs the high-forage diet resulted in a 40% decrease in fecal DM excretion. Starch digestibility and digestibility of whole corn kernels were not affected (P greater than or equal to .62) by diet. Despite similar N intakes, total N excretion was 22% greater (P < .01) for cows fed the high-forage diet than for those limit-fed the high-grain diet. Cow weight and condition score change did not differ (P > .10) between diets. Feed costs were reduced by $.38/d with the high-corn diet vs the high-forage diet. Limit-feeding a corn-based diet is an economically and nutritionally viable alternative to forage-based. diets for nonlactating Holstein cows. XAU: The Ohio State University, Wooster.

CC: L600; L500 AB: Five ruminally fistulated 3-yr-old mature Holstein steers (average BW 691 +/- 23 kg) were used in a 5 X 5 Latin square experiment with a 2 X 2 + 1 factorial arrangement of treatments. Effects of protein concentration and protein source on nutrient digestibility, excretion of DM and fecal N, ruminal fluid volume and dilution rate, ruminal characteristics, and in situ DM disappearance of whole shelled corn, ground corn, and orchardgrass hay were measured in steers limit-fed high-concentrate diets at 1.5% of BW. A negative control basal diet (NC; 9% CP) was supplemented to achieve either 11 or 14% CP; supplemental CP was either from soybean meal (11 and 14% SBM) or a 50:50 ratio of CP from urea and soybean meal (11 and 14% U). Dry matter and OM digestibilities were 5% greater (P < .07) for steers fed the SBM diets than for those fed the U diets. Starch digestibility did not differ (P > .10) among steers fed any of the diets. Nitrogen source did not affect (P > .10) apparent N digestibility or fecal N excretion; however, steers fed the NC diet had the lowest (P < .10) apparent N digestibility compared with those fed all other diets. Ruminal fluid volume was lower (P < .06) when steers were fed the NC diet compared with all other diets; there were no differences (P > .74) among diets for rununal fluid dilution rate. In general, ruminal ammonia N and VFA molar proportions were not affected by protein source or concentration. Although CP concentration affected (P < .06) in situ DM disappearance of ground corn, CP concentration did not ( P > .48) affect total tract digestion of DM or OM. This indicates that CP concentration may have affected site of digestion, but not extent of digestion. When mature ruminants. were limit-fed a corn-based diet to meet primarily a maintenance function, protein source and concentration had little effect on measures of nutrient digestion.

CC: F200; F600 AB: The inheritance of net photosynthesis and transpiration efficiency in spring wheat under drought were studied in two years in order to determine their heritability. The parents, F(1) and segregating generations (F(2), BC(1), BC(2)) of four crosses between each of two drought-resistant and two drought-susceptible genotypes were evaluated under drought in pots under glasshouse conditions. Measurements of gas exchange were made using a portable gas-analysis system. Generation means and variance component analyses of the data suggested that these traits are simply inherited and controlled mainly by additive genetic variation. Narrow-sense heritability estimates varies between crosses from 61% to 84% for net photosynthesis and from 88% for transpiration efficiency. XAU: University of Agriculture, Faisalabad, Pakistan.

CC: F200; F600; F821 AB: A number of resistance sources for the Russian wheat aphid have been reported in the last few years and were used to develop cultivars from current commercial cultivars in various breeding programmes. It can be difficult to distinguish between the cultivars with and without resistant without actual infestation and so in this study we looked at low molecular weight glutenin subunits (LMW-GS) of the two groups. Distinctly different banding patterns were found for the cultivars tested and their isogenic counterparts. Although the LMW-GS and DN1 and DN5 are coded on different chromosomes, the LMW-GS are highly repeatable and banding profiles of each cultivar can be used for the identification of unknown seed.

CC: L600 AB: The influence of fiber source on fiber digestion and mean retention time was investigated. Six fibrous feedstuffs with wide differences in chemical composition and particle size were selected: paprika meal, olive leaves, alfalfa hay, soybean hulls, sodium hydroxide-treated barley straw, and sunflower hulls. Six diets were formulated to contain one of these ingredients as the sole source of fiber. To avoid nutrient imbalances, fiber sources were supplemented with different proportions of a concentrate free of fiber based on soy protein isolate, wheat flour, lard, and a vitamin and mineral mix to obtain diets containing at least 18.5% CP and 5% starch. Fecal apparent digestibility of nonstarch polyeaccharides (NSPd) and its monomers, NDF, NDF-ADL, and ADF-ADL, were determined using four New Zealand White X California growing rabbits per diet. Total, ileorectal, and cecal mean retention times (tMRT, i-rMRT, and cMRT, respectively) were determined for diets based on paprika meal, olive leaves, soybean hulls, and sunflower hulls in 16 does (four per diet) fitted with T-cannulas at the terminal ileum. In both trials, DMI was negatively correlated with the proportion of fine particles (FP: < .315 mm) and positively correlated with the proportion of large particles (LP: > 1.25 mm) (P < .01). Stepwise regression analysis showed that FP was the dietary characteristic best related to digestibilities of NSP, uronic acids, glucose and NDF, tMRT, and cMRT (P < .001), showing a positive correlation with these variables. In all these cases, this procedure selected the proportion of large particles as a second variable in the model. Degree of lignification of NDF, considering lignin. as the difference between ADL and acid detergent cutin, was only included as the third variable for the model of NDF digestibility. Digestibility of NSP was positively correlated with those of NDF, NDF-ADL, and ADF-ADL (r = .82, .87 and .85, respectively, P < .001); the latter was also highly correlated with the digestibility of the glucose included in the NSP fraction (r = .86; P < .001). Cecal mean retention time accounted for 63% of average tMRT, for most of the variability in tMRT (r = .99; P < .001), and was positively related to NSPd (r = .89; P < .001). From these results, we conclude that particle size is a major factor affecting fiber digestion efficiency, rate of passage, and feed intake in rabbits. XAU: Universidad Politecnica, Madrid, Spain.

ID: codominant-polymorphism. CC: F200 AB: The assessment of polymorphism exhibited by molecular markers is an arduous but essential task that facilitates the use of molecular tools by breeders and geneticists. For that purpose, the value of a wheat composite population was assessed for characterizing the diversity of restriction fragment length polymorphism (RFLP) markers developed by INRA-Genoble. The polymorphism of 13 genomic probes was measured over a set of 80 inbred lines randomly extracted by single-seed descent from a composite-cross of 16 wheat lines. The 13 probe-enzyme combinations revealed 27 loci with codominant polymorphism. As many bands were so far unmapped, the segregational analysis of the progenies appeared very suitable for complex patterns, both in determining allelic relationships and in revealing linkage between loci. Allelic diversity, band sizes and chromosomal location assessed from nullisomic-tetrasomic lines are given for the 27 loci. XAU: INRA, Gif sur Yvette, France.

To determine the number of genes and their arm location, ear emergence time under a controlled environment was investigated using ditelosomic lines and homozygous recombinant substitution lines developed between chromosome 3A homologues from 'Timstein' and 'Chinese Spring' (CS) in a CS genetic background. Because the ear emergence distribution was discontinuous and two separate modes were produced, the 86 recombinant lines could be divided into 21 lines as the early 'Tinstein' 3A type and 65 lines as the late CS type. This agrees with the 1:3 independent segregation of two genes both located on chromosome 3A. Therefore, two hypotheses can be proposed, either CS ('Timstein' 3A) carries two genes and both are necessary to give early ear emergence, or one gene for early emergence is present on 'Timstein' 3A, but a suppressor is on CS 3A. The behavior of ditelosomic 3AL and 3AS lines, with an ear emergence time identical to that of CS, suggested that one gene is located on the long arm and the other is on the short arm.

CC: L500; L100 AB: 1. A 70-d experiment was conducted to determine the response of 26-week-old laying pullets to cereal-free diets based on maize offal, cassava peel and full-fat cashew nut meal (CNM) in comparison with a standard 550 g maize/kg reference diet. The 4 test diets all contained 315 g CNM/kg 232(.)5, 155(.)0, 77(.)5 and 0(.)0 g/kg of maize offal in combination with 77(.)5, 155(.)0, 232(.)5 and 315(.)0 g/kg of cassava peel, respectively. 2. Pullets fed on the 4 CNM-based diets consumed (P<0(.)05) less food than those fed on the reference diet; they also had lower (P<0(.)05) rates of lay, produced less (P<0(.)05) egg mass, had lower (P<0(.)05) food conversion efficiencies and their eggs had a lighter (P<0(.)05) yolk colour. Pullets fed some of the CNM-based diets also gained more (P<0(.)05) weight, the heaviest (P<0(.)05)being birds reared on the diet containing 315 g/kg cassava peel. Egg weight, shell thickness and albumen height from all eggs were similar. Pullets fed on the CNM-based diets had inferior (P<0(.)05) retention of dry matter and protein. 4. It was concluded that feeding full-fat CNM allowed for high dietary inclusion rates of cassava peel and maize offal and the resultant diets, which contained no maize, supported satisfactory performance of laying hens.

ID: mucosal-crypts. CC: L500 AB: 1. Two experiments were carried out to investigate the addition of 1(.)3 kg water per kg air-dry mash diets containing high proportions (600 to 700 g/kg) of ground cereal grains (wheat, barley or oats) on broiler performance and the structure and function of the gastro-intestinal tract. 2. Chicks at the age of 7 d were fed on the wheat-, barley- or oats-based diets in the dry or wet forms for 35 d. Food and water intakes were recorded daily while body weight was measured weekly. Two birds from each treatment were killed each week to measure gut size and the viscosity of gut contents. Tissue samples from various digestive segments were histo-morphologically examined to determine the thickness of tissue layers, size of tissue glands, villa heights, crypt depths and thickness of tunica muscularis. Crypt cell proliferation rate (CCPR) for each segment was also determined using a metaphase arrest technique. 3. The results from both experiments showed that wetting food significantly (P<0(.)05) increased food intake, total water intake and body weight gain of broiler chickens. The body weight gain of birds were proportional to their food intakes so that the efficiency of food utilisation was similar for all treatments. Dry matter retention of food tended to increase in birds given wet food from 7 to 21 d but not thereafter, compared to the dry-fed birds. Although water intake from the water bottle was significantly (P<0(.)05) reduced in birds given wet food, total water intakes from the water bottle plus that from food were significantly (P<0(.)05) higher in the wet-fed birds than in the dry-fed birds. The ratio of total water to dry food intake was, however, similar in both feeding regimens. 4. The fresh empty weight of the gut was increased by wet-feeding while its relative weight to body weight and the length of gut was not affected by dietary treatments. Significantly greater development of the tissue glands in the proventriculus and gizzard was observed in the birds given wet food; this was associated with the reduced thickness of the muscular layer of these segments. An increase in villus height was also observed in duodenum, small intestine, caeca and colon of birds given wet food, compared to those given dry food. CCPR was significantly (P<0(.)05) reduced by wet-feeding throughout the digestive tract. This was associated with a significant decrease in the mean viscosity of the gut contents and the concentration of volatile fatty acids (VFAs) in the caeca. 5. Wetting diets based on cereal grains caused a significant improvement in the performance of broiler chickens. The mechanism of the beneficial effects of wet feeding could be attributed to the decreased viscosity of gut contents; the greater development of the layer of villi in the digestive segments and the reduced CCPR in the crypts of the epithelium.

CC: F200 AB: Differential screening cDNA libraries of unfertilized egg cells and in vitro zygotes of maize resulted in the isolation of more than 50 different genes whose expression is up- or down-regulated after in vitro fertilization (IVF). Amoung these genes we identified a cDNA encoding the eukaryotic translation initiation factor eIF-5A. This highly conserved factor is thought to be necessary for selective mRNA stabilization and translation. It is also the only known protein that contains the unusual amino acid hypusine which is required for biological activity. High transcript amounts are stored in the egg cell, which is, in terms of metabolism, relatively inactive. Upon fertilization transcript amounts decrease, in contrast to metabolically inactive embryos in which the transcript cannot be detected and transcript levels increase up on germination. The expression pattern during the first embryonic cell cycle is also different from that observed during the somatic cell cycle: egg cells in the G0 phase contain high transcript levels, while arrested suspension cells contain few transcripts. In the somatic cell cycle, eif-5A is strongly induced during the G1 phase and transcripts are continuously degraded during the S, G2 and M phases until new induction during the G1 phase of the next cycle. eif-5A, a member of a small gene family in maize, is expressed in most maize tissues investigated. Based on our results, we suggest that the unfertilized egg cell of maize, although relatively inactive regarding its metabolism, is prepared for selective mRNA translation that is quickly triggered after fertilization. We also suggest that the regulation of eif-5A in the first embryonic cell cycle is. different from the somatic cell cycle. XAU: University of Hamburg, Hamburg, Germany.

CC: T300; T000 AB: Under states of protein deficiency, the dietary limiting amino acid, rather than protein content, can act as the dietary stimulus to control diet selection. If fact, threonine-deficient rats will alter their diet selection patterns solely on the basis of very small changes (0.009 g/100 g) in the dietary threonine concentration. In these studies, we assessed whether lysine-deficient rats will also alter their diet selection patterns on the basis of small changes in dietary Lys concentration. In all experiments, growing rats were adapted to diets in which the protein fraction (purified amino acids or wheat gluten) was limiting in Lys. They were then given a choice between the adaptation diet (AD) diet and a slightly more deficient diet. Rats that were adapted to a Lys-deficient diet (0.25 g Lys/100 g) selected their AD over diets containing as little as 0.01% less Lys (P < 0.01) within 5 d. To determine how deficient rats must be before they alter their selection patterns, rats were adapted to diets containing various levels of Lys, i.e., 2 levels below the requirement for growth and 2 levels above the requirement for growth, but below the requirement for maximal nitrogen retention. Only rats adapted to diets containing Lys below their requirement for growth selected their AD over a diet containing 0.05% less Lys (P < 0.005). Finally, to determine whether rats will alter their selection to whole protein-based diets, rats were adapted to 25% wheat gluten diets supplemented with 0.03-0.21% Lys. Rats selected the AD over a diet containing as little as 0.09% less supplemental Lys by d 4 of the trial (P < 0.05). We conclude that rats are sensitive to changes as small. as 0.01% in dietary Lys concentration, but that sensitivity requires prior adaptation to Lys-deficient diets.

CC: L500; L100 AB: In Exp. 1, 72 Targhee lambs (initial BW 22.1 +/- .3 kg) were used to determine the effects of energy source (alfalfa pasture vs limit-fed, all-concentrate) and ionophore addition on performance, visceral organ mass, and carcass characteristics. There were no differences (P > .10) in ADG or gain/feed due to ionophore supplementation. Lambs that grazed alfalfa had greater (P < .05) liver, omasum, abomasum, small intestine, cecum, and large intestine weights than did lambs fed the concentrate diet. Lambs fed the concentrate diet had greater (P < .01) hot carcass weights, larger (P < .01) loin eye areas, and greater (P < .001) dressing percentages than lambs that grazed alfalfa. In Exp. 2, lambs offered the concentrate diet had greater (P < .001) DM and OM digestibilites than lambs offered alfalfa (89.5 and 91.1 vs 72.4 and 72.2%, respectively) Apparent and true N digestibilities were greater (P < .001) for the concentrate diet than for alfalfa (90.9 and 101.7 vs 77.7 and 91.9% respectively) Likewise, grams of N retained per day were twice as great (P < .001) with the concentrate diet than with alfalfa (14.9 vs 6.0 g/d). The greater visceral organ mass and resulting increases in energy and protein requirements in lambs that grazed alfalfa were probably responsible for the lesser hot carcass weight and dressing percentage compared with lambs fed 100% concentrate.

ID: molecular-sequence-data. genbank/y17332-. CC: F200 AB: A clone encoding a proline-rich protein (ZmPRP) has been obtained from maize root by differential screening of a maturing elongation root cDNA library. The amino acid sequence deduced from the full-length cDNA contains a putative signal peptide and a highly repetitive sequence containing the PEPK motif, indicating that the ZmPRP mRNA may code for a cell wall protein. The PEPK repeat is also found in a previously reported wheat sequence but differs from the repeated sequences found in hydroxyproline-rich glycoproteins (HRGP) and in dicot proline-rich proteins (PRP). In the maize genome, the ZmPRP protein is encoded by a single gene that is expressed in maturing regions of the root, in the hypocotyl and in the pericarp. In these organs, the ZmPRP mRNA accumulates in the xylem and surrounding cells, and in the epidermis. No ZmPRP mRNA was found in the phloem. The pattern of mRNA accumulation is very similar to the one observed for genes coding for proteins involved in lignin biosynthesis and, like most cell wall proteins, ZmPRP synthesis is also induced by wounding. These data support the hypothesis that ZmPRP is a member of a new class of fibrous proteins involved in the secondary cell wall formation in monocot species. XAU: CID-CSIC, Barcelona, Spain.

CC: F200; F600 AB: Although maize endosperm undergoes programmed cell death during its development, it is not known whether this developmental feature is common to cereals or whether it arose inadvertently from the selection process that resulted in the enlarged endosperm of modern maize. Examination of wheat endosperm during its development revealed that this tissue undergoes a programmed cell death that shares features with the maize program but differs in some aspects of its execution. Cell death initiated and progressed stochastically in wheat endosperm in contrast to maize where cell death initiates within the upper central endosperm and expands outward. After a peak of ethylene production during early development, wheat endosperm DNA underwent internucleosomal fragmentation that was detectable from mid to late development. The developmental onset and progression of DNA degradation was regulated by the level of ethylene production and perception. These observations suggest that programmed cell death of the endosperm and regulation of this program by ethylene is not unique to maize but that differences in the execution of the program appear to exist among cereals.

CC: F200 AB: Expression patterns of chitinase transcripts induced by N-acetylchitooligosaccharide elicitor were analyzed by northern blot hybridization in order to reveal a signal transduction pathway leading to the activation of class I chitinase genes (Cht-1 and Cht-3), which may play an important role in producing N-acetylchitooligosaccharide elicitor. The transcription level of both genes was enhanced in response to N-acetylchitooligosaccharides larger than pentaose at subnanomolar concentrations. These structure and dose dependencies were consistent not only with those for a 75 kDa high-affinity binding protein for N-acetylchitooligosaccharide elicitor in the plasma membrane, but also with other series of cellular responses including phytoalexin production and the expression of elicitor-responsive genes (EL2, EL3). Therefore, the elicitor signal to evoke these cellular responses including the activation of the chitinase genes could be common and transmitted into cells through the 75 kDa protein. However, the signal transduction pathway for the activation of the chitinase genes appeared to diverge from those for the other elicitor-responsive genes shortly after the signal perception. It was shown that the induction of chitinase expression by N-acetylchitooligosaccharide would require protein phosphorylation, but not de novo protein synthesis. The oxidative burst was demonstrated not to be necessary for transcriptional induction of the all four elicitor-responsive genes (Cht, PAL, EL2, FL3) by N-acetylchitooligosaccharide.

Plants infected with the fungal endophyte Epichloe festucae were detected in all twenty-seven populations studied in the province of Salamanca, Spain. Infection frequencies in six selected populations ranged from 44% to 92% (average, 70%) of the plants. Infected plants were almost always symptomless. These results suggest that the association between E. festucae and F. rubra is common and occurs at a high frequency in Mediterranean permanent grasslands. XAU: CSIC, Salamanca, Spain.

CC: F821; J700 AB: The effect of management of maize residues on the population of insects inimical to the establishment of alfalfa, Medicago sativa L., was examined 1 month after sowing. Alfalfa was sown in early and late April, and late May for 3 consecutive years in Centre County, Pennsylvania, USA. The sowings were made by conservation tillage (direct drilled into maize residue with minimal disturbance of soil) into three different maize residues after (1) silage, (2) silage-plus-winter rye cover and (3) grain. A fourth sowing was by conventional tillage (spring ploughing and harrowing maize residue) after grain. A pesticide, carbofuran (granular formulation) was applied at sowing to half of the plots. Methiocarb bait, a molluscicide, was applied as a split application to the same plots, one-half at sowing and the remainder 2 weeks later. Alfalfa plots in the silage-plus-rye maize residues were colonized with fewer insects than the other residue treatments. Excessive growth of rye in early spring that was not successfully suppressed by herbicide treatment produced vigorous rye plants and fewer alfalfa seedlings. Consequently, silage plus rye had the lowest yield of alfalfa in early April sowings in 2 out of 3 years. Insects known to feed on alfalfa, such as tarnished plant bugs, Lygus lineolaris (Palsot de Beauvois), the plant bug, Plagiognathus politus Uhler, pea aphids, Acyrthosiphon pisum (Harris), and meadow spittlebugs, Philaenus leucophthalmus spumarius (L.), were collected by sweep net 1 month after sowing and less often in the silage-plus-rye treatment. These species were present in greater numbers in the other maize residues that had significantly more alfalfa. forage. The insidious flower bug, Orius insidious (Say), and a damsel bug, Nabis americoferus Carayon, were collected in significantly greater numbers in the early April sowings, which corresponded with the peak populations of pea aphid. The potato leafhopper, Empoasca fabae (Harris), was most abundant in plots sowed in late April or late May. Pesticide treatment applied at the time of sowing had very little effect on numbers of insects collected by sweep net 1 month later in 1986 and 1988. However, pesticide treatment significantly increased yield by 280 kg ha-1 in 1987, even though sweep net collections of insects were not reduced by the pesticide treatment. Therefore, the beneficial effects of the pesticide could not be explained on the basis of the insects collected. The highest yields of alfalfa were obtained from the early April sowing into maize residues. This coincided with the time when the majority of alfalfa pests were less abundant than in later sowings; fewer pests were found on the sowings into silage-plus-rye residue. Also, when the rye forage yield was combined with the alfalfa yield, this became the most productive system.

CC: F200; F600; F130 AB: The increased seed size of induced polyploid forms has been an important component of improved seedling vigour of small-seeded pasture species. Nitrous oxide was used to produce an octoploid form of the F3 generation of a cross between the closely related tetraploid cultivars, Uneta and Australian phalaris (Phalaris aquatica L.; 2n = 28). A high degree of recovery of octoploid plants (30%) was attained by nitrous oxide treatment. Increases in seed weight, glume length, stomatal guard cell length and pollen grain diameter of 13-84% were recorded in glasshouse grown plants of the octoploid compared with the tetraploid parent population. In a field experiment the superior establishment of the octoploid compared with the tetraploid was interpreted as evidence of the better establishment capacity of the octoploid from deep placement of the seed. However, there was a greater loss of octoploid seedlings over summer, and a greater reduction in the basal area of the sward under continuous grazing than in the tetraploid. Although the octoploid swards produced significantly less phalaris dry weight than the tetraploid in exclosures, the total herbage dry weight of the two types was not significantly different in three of four cuts taken over 2 years. This result supports the view that the more erect, sparsely tillered growth habit of the octoploid phalaris is conducive to the productivity of other sward components.

CC: F120; F600 AB: Forage crops in Mediterranean environments are characterized by variable seed and forage production. Knowledge of the effects of agronomic factors on annual clovers grown in pure stand and in association with grasses is essential for their effective exploitation of the available environmental resources. Herbage and seed production were evaluated in southern Italy in an experiment with winter annual forage crops during the years 1992-95. Clovers (Trifolium alexandrinum L., berseem; T. incarnatum L., crimson; T. resupinatum L., Persian; and T. squarrosum L., squarrosum) and graminaceous forage crops (Hordeum vulgare L., barley; and Lolium multiflorum Lam., Italian ryegrass) were used to examine the agronomic effects of irrigation and harvest management. The clovers were evaluated in pure stand and in mixture, whereas the graminaceous species were evaluated only in mixtures. The mixtures were sown in alternating, equally spaced rows. The parameters evaluated were forage dry-matter yield, seed yield and its components. The results showed wide differences in forage production between clovers in pure stands and in binary mixtures. Mean dry-matter production from forage harvest of pure stands of irrigated clovers taken when 10-15% of the stems were flowering yielded 4(.)36 t ha-1, that is 0(.)67 and 0(.)55 of that of irrigated mixtures of clovers with either Italian ryegrass or barley, respectively, harvested when 10-20% of the graminaceous components were at the heading stage. The forage yield of non-irrigated pure stands of clovers was 0(.)60 of that of irrigated plots, whereas non-irrigated mixtures yielded 0(.)82 and 0(.)86 of that the irrigated treatments for Italian ryegrass or barley mixtures. The. mean seed yield of non-irrigated pure stands of the clovers was 0(.)51 of that of irrigated stands, which yielded 451 kg ha-1. Persian clover gave the highest seed yields (732 kg ha-1 under irrigation). These higher yields were related to a higher number of fructiferous organs per stem in Persian clover. When a forage harvest had previously been taken on irrigated clover plots, the subsequent mean seed yields were greatly reduced to 0(.)76 for berseem and 0(.)21 for Persian clover and were almost negligible for crimson and squarrosum clover. When irrigated and grown in mixtures with Italian ryegrass, only berseem produced a worthwhile yield of 0(.)36 compared with that of pure clover taken for seed without a forage harvest; mixtures with barley gave yields of 0(.)71, 1(.)07 and 0(.)20 for berseem, crimson and Persian clovers, respectively, compared with seed yield from uncut pure clover.

CC: F500; J500; J200 AB: The effects of NH4(+)-N, NO3(-)-N or urea-N addition on N uptake by perennial ryegrass (Lolium perenne), 15N recovery and pH of four limed and unlimed soils were determined in a pot experiment over 10 weeks. The best form of N in terms of herbage N uptake and fertilizer recovery differed between the soils. Recovery of applied 15N in herbage was greatest for the soil with the lowest pH and highest organic matter content, and overall recovery in the soil-plant system was influenced more by soil type than by N form. There was always an apparent mineralization of soil N when perennial ryegrass was present. Soil pH changes ranged from +0(.)11 to -0(.)58 units for the unlimed soils and from +0(.)03 to -1(.)06 units for the limed soils. The use of NO3(-)-N rather than NH4(+)-N or urea-N avoided further acidification. Lime increased herbage N only from the soils with the lowest pH values. Although the acidifying effect of NH4(+)-fertilizer was alleviated, Liming may increase nitrification and possibly N loss via denitrification and/or leaching in the field. The major influence of soil type on herbage N uptake, pH response to the treatments and fertilizer recoveries implies that liming and fertilizer N management decisions should consider soil characteristics, such as organic matter, clay contents and pH.

CC: F500; F600; F130; F120; J100 AB: To represent nitrogen cycling in a low input grass/legume pasture system, a previously developed, weather-driven grass/white clover growth model has been adapted to become the crop growth component of the soil nitrogen dynamics model SOILN. This provides a means of simulating nitrogen uptake by a grass/white clover crop, an important component of the overall nitrogen balance in low-input grassland systems. Crop growth is represented by a photosynthesis equation adapted to take account of competition between the two crops for resources of light, water and nitrogen in the soil. Water shortage is represented by linked simulations with the soil water and heat model SOIL, and nitrogen shortage by links with the SOILN model. Nitrogen fixation has been introduced according to an equation for potential fixation reduced by environmental factors, particularly temperature. Transfer of nitrogen-rich clover plant material to the soil nitrogen pools of SOILN (from where it becomes available as a nutrient for grass) is also represented. The model is tested by comparing simulated cut crop yields and nitrogen content of cut material with measured data from perennial ryegrass/white clover at a test site. Soil nitrogen processes in the model are tested by comparing simulated and measured nitrate in drainflows. Apart from some discrepancies between simulated and measured results attributable to the inherent instability of a mixed crop system, agreement is reasonable by the standards of biological system models, indicating that the combined model gives a realistic representation of carbon and nitrogen processes in grassland with a grass, legume mixed crop.

CC: F130; F600; J500; R300; F120 AB: The expected reduction in the use of fertilizer nitrogen (N) on grassland in the Netherlands has led to renewed interest in white clover. Therefore, the performance of a newly sown perennial ryegrass/white clover sward on clay soil was assessed during 4 consecutive years. The experiment consisted of all combinations of two defoliation systems, i.e. one or two silage cuts per year (S1, S2), spring N application rate, i.e. 0 or 50 kg ha-1 year-1 (N0, N50), and the management system, i.e. rotational grazing and cutting, or cutting only (RGC, CO). The overall mean white clover cover was 30%. All treatments affected white clover cover, which was 8% higher with S2 than with S1 6% higher with N0 than with N50 and 12% higher with CO than with RGC. The overall mean annual dry-matter (DM) yield (13(.)1 t ha-1 year-1) was significantly affected only by the management system: in two relatively wetter years, the annual DM yield was 1(.)19 t ha-1 higher with RGC than with CO, whereas there was no difference in two relatively drier years. Nitrogen application increased the DM yield in the first cut by 7(.)0 kg kg-1 N applied, but had no significant effect on the annual DM yield. Herbage quality was not affected by the experimental treatments. The average in vitro organic matter digestibility was 0.801, and the average crude protein content was 193 g kg-1 DM. With the expected reduction in the use of fertilizer N, perennial ryegrass/white clover swards should be seriously considered as an altemative option to perennial ryegrass swards on these clay soils.

CC: F120; X100 AB: The objective of this study was to develop a linear programming model to analyze the production schedule of rice seedlings grown in the nursery. The model can help the managers of rice seedling centers in Taiwan to make better production decisions and maximize profit (all monetary units are expressed in US dollars). To verify the model, a rice seedling center was chosen for analysis of the first rice crop in 1997. The results show that the cost is about $51,856 yielding a profit of about $21,861 to supply 91,385 boxes of seedlings. The maximum number of boxes in the greening field is 4,600. The minimum production in each batch affects the cost significantly. The results show costs of about $41,884 for 4,000 boxes batch(-1), while costs rise to about $56,522 for 6,000 boxes batch(-1). Consequently, using the model to predict the production schedule not only reduces costs but also provides the seedling in the best status for transplanting. The demand quantities of the boxes in each day during the transplanting period can be expressed by a fourth-order polynomial. Here, a demand quantity ranging from 73,928 to 110,892 boxes is generated by the polynomial to analyze the production schedule. The result shows that the production scale could be expanded to about 110,892 boxes with the same hardware. In this status, the profit could be increased to about $26,667, and the cost/profit ratio is 2.35. The relationship between supply quantity scale (x) and greening field size (y) can be calculated by a regression formula (y = 0.4609x + 3.143), where both units are in 10,000 boxes.

CC: F600 AB: The objectives of this study were: (1) to quantify post-anthesis kernel cytokinin levels in 'Tibet Dwarf', a dwarf wheat (Triticum aestivum L.) that accumulates elevated quantities of leaf cytokinins; and (2) to measure the effects of temperature on kernel cytokinin accumulation and mature kernel mass in this wheat. Post-anthesis kernel cytokinin accumulation was measured in control plants maintained at 25/12 degrees C (day/night) and treated plants which received a 7 d exposure to 35/25 degrees C beginning at anthesis and grown to maturity at 25/15 degrees C. Zeatin (Z), dihydrozeatin (diHZ) and their respective ribosides were the predominant cytokinins detected in control and treated plants. Minimal quantities of isopentenyl adenine-type cytokinins were detected. Kernel cytokinin content peaked within 3 d after anthesis in both groups and returned to baseline levels within 1-2 d. Relative to controls, exposure to high temperature reduced kernel cytokinin content approx. 80% within 1 d after anthesis. Because kernel cytokinin in control Tibet Dwarf plants exceeded that previously measured in other varieties by over 100-fold, the reduced content of treated plants still exceeded that of untreated plants of other varieties. The increased cytokinin content did not enhance thermotolerance. The temperature treatment reduced mature kernel weights approx. 27%, similar to reductions measured in other wheat varieties.

CC: F400; J200; F600 AB: The effects of soil bulk density and hence strength on two contrasting species of herbaceous annuals, the dicot sunflower (Helianthus annuus L.) and the monocot maize (Zea mays L.), were investigated by comparing the morphology and mechanics of field-grown plants in soil with a low and high bulk density. Soil with a low bulk density had a significantly lower penetration resistance (118 +/- 4(.)4 kPa) than the high bulk density soil (325 +/- 12(.)2 kPa; P < 0(.)0001). Soil strength affected shoot and root systems of both species but had no significant effect on shoot height. In both species roots were thicker closer to the stem base in strong soil compared to those in weaker soil. Sunflower tap-roots growing in strong soil tapered more rapidly than those in weak soil. Only in maize, however, were roots growing in weak soil stiffer than those in strong soil. Despite only small absolute differences in the penetration resistance of the soil both species growing in strong soil had greater anchorage strength than those in weak soil. As a consequence more plants in weak soil lodged compared with those growing in strong soil. This study shows that plants can, to a small extent, respond to changes in soil strength, but that changes do not appear to compensate fully for alterations in soil conditions. Furthermore it may be possible, by manipulating soil strength, to control lodging. XAU: De Montfort University Lincoln, Riseholme, Lincoln.

ID: countercurrent-steep-system. flow-rate. CC: Q104 AB: The purpose of this work was to evaluate the stability of a countercurrent steep system to ensure that variables, including temperature, pump flow rate and steepwater profiles remain stable during long periods of operation. Four runs of a laboratory-scale continuous countercurrent steep system were used to evaluate its thermal and mechanical stability. One run was started with fresh steepwater while the other three were inoculated with light steepwater obtained from a wet-milling plant. Variables, such as steep temperature, steepwater recycle rate and light steepwater draw rate, were monitored. Steepwater characteristics, including pH, SO(2) concentration, lactic acid concentration and steepwater solids content were determined. Six to eight days were required for all of the steepwater variables (pH, SO(2) and lactic acid concentration and steepwater solids content) to reach steady state when light steepwater from a plant was used to inoculate the system. When fresh steepwater was used, 12 d were needed. The average steep temperature of the 16 tanks during 16 d of continuous operation was 50 +/- 1 degree C with a setpoint of 50 +/- 2 degrees C. The average pump flow rate for the 8 pumps was 5.0 +/- 0.1 mL/s when the setpoint was 5.0 mL/s. The average light steepwater draw rate over nine days was 593 +/- 49 mL/kg when the setpoint was 600 mL/kg. Corn steeped in this system was wet-milled and product yields were reproducible.

CC: F600; B200; W000 AB: Potato and wheat plants were grown for 50 d at 400, 1000 and 10000 micromol mol(-1) carbon dioxide (CO(2)), and sweetpotato and soybean were grown at 1000 micromol mol(-1) CO(2) in controlled environment chambers to study stomatal conductance and plant water use. Lighting was provided with fluorescent lamps as a 12h photoperiod with 300 micromol m(-2) s(-1) PAR. Mid-day stomatal conductances for potato were greatest at 400 and 10000 micromol mol(-1) and least at 1000 micromol mol(-1) CO(2). Mid-day conductances for wheat were greatest at 400 micromol mol(-1) and least at 1000 and 10000 micromol mol(-1) CO(2). Mid-dark period conductances for potato were significantly greater at 10000 micromol mol(-1) than at 400 or 1000 micromol mol(-1), whereas dark conductance for wheat was similar in all CO(2) treatments. Temporarily changing the CO(2) concentration from the native 1000 micromol mol(-1) to 400 micromol mol(-1) increased mid-day conductance for all species, while temporarily changing from 1000 to 10000 micromol mol(-1) also increased conductance for potato and sweetpotato. Temporarily changing the dark period CO(2) from 1000 to 10000 micromol mol(-1) increased conductance for potato, soybean and sweetpotato. In all cases, the stomata responses were reversible, i.e. conductances returned to original rates following temporary changes in CO(2) concentration. Canopy water use for potato was greatest at 10000, intermediate at 400, and least at 1000 micromol mol(-1) CO(2), whereas canopy water use for wheat was greatest at 400 and similar at 1000 and 10000 micromol mol(-1) CO(2). Elevated CO(2) treatments (i.e. 1000 micromol mol(-1)) resulted in increased plant biomass. for both wheat and potato relative to 400 micromol mol(-1), and no injurious effect were apparent from the 10000 micromol mol(-1) treatment. Results indicate that super-elevated CO(2) (i.e. 10000 micromol mol(-1)) can increase stomatal conductance in some species, particularly during the dark period, resulting in increased water use and decreased water use efficiency.

ID: coelorachis-aurita. CC: F600 AB: We investigated spikelet development in four distantly related species of the grass tribe Andropogoneae to determine whether spikelet development and the formation of unisexual florets are uniform throughout the tribe. We studied development in Bothriochloa bladhii, Coelorachis aurita, Heteropogon contortus, and Hyparrhenia hirta, and compared these with Panicum, a member of the sister tribe Paniceae. Many aspects of spikelet development in the species we have studied correlate with what is already known for Tripsacum and maize (both Andropogoneae), despite variation in how unisexual florets are distributed on the plant. The formation of unisexual spikelets is also uniform. All florets initiate both pistil and stamen primordia. In florets destined to be male, cell death occurs in the subepidermal layers of the gynoecium after the formation of a gynoecial ridge. In florets destined to be female, there is no apparent cell death in the stamens, but growth ceases after anther formation. The similarity in spikelet development and the formation of unisexual florets point to a common genetic mechanism for sex determination throughout the Andropogoneae and possibly the entire Panicoideae. Use of a cell death pathway to cause gynoecial abortion may be the basis of one morphological character that defines the subfamily. XAU: Boston College, Chestnut Hill, MA.

The moisture content variation in lots of corn dried in three commercial dryer types was measured along with the grain quality (as indicated by the percentage of stress-cracked kernels). Corn exiting a high-temperature dryer regardless of the type, had a standard deviation in the moisture content of the individual kernels of 3 to 5%, but this figure decreased to about 1% within three days. The corn dried in the concurrent flow dryers showed the fewest stress cracks, that dried in the crossflow dryers the highest percentage of stress cracks. XAU: Purdue University, West Lafayette, IN.

CC: Q104; X200 AB: Two statistical and one neural network classifiers were applied and empirically compared for the classification cereal grain kernels (e.g., Canadian Western Red Spring (CWRS) wheat, Canadian Western Amber Durum (CWM)) wheat, barley, rye, and oats) and for the classification of healthy and six types of damaged (e.g. broken, grass-green/green-frosted, black-point/smudge, mildewed, heated, and bin/fire-burnt) CWRS wheat kernels, using selected morphological and color features extracted from the grain sample images. For the classification of cereal grain kernels and the classification of healthy and damaged CWRS wheat kernels, the k-nearest neighbor statistical classifier and the multilayer neural network (MNN) classifier gave similar and the best classification results. Using a k-nearest neighbor classifier with a selected set of 15 morphological and 13 color features, the average classification accuracies were 98.2, 96.9, 99.0, 98.2, and 99.0% for CWRS wheat, CWAD wheat, barley, rye, and oats, respectively, when trained and tested with three different training and testing data sets. Using a k-nearest neighbor classifier with a selected set of 24 color and four morphological features, the average classification accuracies were 92.5 (healthy), 90.3 (broken), 98.6 (mildewed), 99.0 (grass- green/green-frosted), 99.1 (black-point/smudged), 97.5 (heated), and 100.0% (bin/fire-burnt), respectively, when trained and tested with three different training and testing data sets. The classification accuracies achieved using a parametric classifier were lower than the classification accuracies achieved using both the k-nearest neighbor and the MNN classifiers.

ID: omega-3-fatty-acids. omega-6-fatty-acids. CC: T300; T200; X380 AB: Fatty acids in the diet are readily incorporated into lipids in various tissues. However, it is not clear whether all tissues have the same level of incorporation. Second, (n-6) unsaturated fatty acids increase the fluidity of membranes, but this has not been shown for (n-3) fatty acids. In this study, we measured the incorporation of (n-6) and (n-3) fatty acids into erythrocyte membrane lipids and studied their effects on the fluidity of erythrocyte membranes. One group of female miniature swine was made hypercholesterolemic by feeding the swine cholesterol and lard for 2 mo; the other group served as controls and was fed a stock diet. Both groups were then fed either corn oil or menhaden oil or a mixture of the two for 23 additional weeks. Blood was collected at 0, 2, 4, 12 and 23 wk after initialization of the experimental diets, and fatty acid composition of phospholipids was assessed. Membrane phospholipids of pigs fed menhaden oil had elevated (n-3) fatty acids (20:5 and 22:6), and lower 18:2 than those fed corn oil. There was no difference in 20:4 content. The fatty acid changes occurred as early as 2 wk after consumption of the corn oil or menhaden oil in pigs previously fed a stock diet, but it took longer in pigs previously fed lard + cholesterol, indicating residual effects of pretreatment. Menhaden oil increased anisotropy (indicating decreased fluidity) more than corn oil for the nonpolar probe diphenylhexatriene (DPH) at earlier time points, but not at 23 wk. Erythrocyte membrane fluidity was significantly related to membrane polyunsaturate content, with (n-6) fatty acids having a greater influence than (n-3) fatty acids. A comparison of the present red blood cell fatty. acid compositions with brain synaptosome fatty acid compositions for the same animals showed poor correlations for some of the fatty acids. There was no significant direct relationship between docosahexaenoate (DHA) concentrations in erythrocyte membranes with DHA concentrations in brain synaptosomes from cerebellum, forebrain and caudate nucleus.

PT: Article SF: IND DE: zea-mays. domestication-. genetic-diversity. selection-. selective-breeding. nucleotides-. polymorphism-. plant-breeding. CC: F200 AB: The domestication of all major crop plants occurred during a brief period in human history about 10,000 years ago. During this time, ancient agriculturalists selected seed of preferred forms and culled out seed of undesirable types to produce each subsequent generation. Consequently, favoured alleles at genes controlling traits of interest increased in frequency, ultimately reaching fixation. When selection is strong, domestication has the potential to drastically reduce genetic diversity in a crop. To understand the impact of selection during maize domestication, we examined nucleotide polymorphism in teosinte branched1, a gene involved in maize evolution. Here we show that the effects of selection were limited to the gene's regulatory region and cannot be detected in the protein-coding region. Although selection was apparently strong, high rates of recombination and a prolonged domestication period probably limited its effects. Our results help to explain why maize is such a variable crop. They also suggest that maize domestication required hundreds of years, and confirm previous evidence that maize was domesticated from Balsas teosinte of southwestern Mexico.

CC: F200; F600 AB: A MADS family gene, OsMADS6, was isolated from a rice (Oryza sativa L,) young flower cDNA library using OsAMDS1 as a probe. With this clone, various MADS box genes that encode for protein-to-protein interaction partners of the OsMADS6 protein were isolated by the yeast two-hybrid screening method. On the basis of sequence homology, OsMADS6 and the selected partners can be classified in the APETALA1/AGAMOUS-LIKE9 (AP1/AGL9) family. One of the interaction partners, OsMADS14, was selected for further study. Both genes began expression at early stages of flower development, and their expression was extended into the later stages. In mature flowers the OsMADS6 transcript was detectable in lodicules and also weakly in sterile lemmas and carpels, whereas the OsMADS14 transcript was detectable in sterile lemmas, paleas/lemmas, stamens, and carpels. Using the yeast two-hybrid system, we demonstrated that the region containing of the 109th to 137th amino acid residues of OsMADS6 is indispensable in the interaction with OsMADS14. Site-directed mutation analysis revealed that the four periodical leucine residues within the region are essential for this interaction. Furthermore, it was shown that the 14 amino acid residues located immediately downstream of the K domain enhance the interaction, and that the two leucine residues within this region play an important role in that enhancement.

ID: molecular-sequence-data. CC: F200; F600 AB: The starch granules of hexaploid wheat (Triticum aestivum) contain a group of three proteins known as SGP-1 (starch granule protein-1) proteins, which have apparent molecular masses of 100, 108, and 115 kD. The nature and role of these proteins has not been defined previously. We demonstrate that these polypeptides are starch synthases that are present in both the starch granule and the soluble fraction at the early stages of wheat endosperm development, but that are exclusively granule bound at mid and late endosperm development. A partial cDNA clone encoding a fragment of the 100-kD protein was obtained by screening a wheat endosperm cDNA expression library using monoclonal antibodies. Three classes of cDNA were subsequently isolated from a wheat endosperm cDNA library by nucleic acid hybridization and were shown to encode the 100-, 108-, and 115-kD proteins. The cDNA sequences are highly homologous to class II starch synthases and have the highest homology with the maize SSIIa (starch synthase IIa) gene. mRNA for the SGP-1 proteins was detected in the leaf, pre-anthesis florets, and endosperm of wheat and is highly expressed in the leaf and in the grain during the early to mid stages of development. We discuss the roles of the SGP-1 proteins in starch biosynthesis in wheat. XAU: Commonwealth Scientific and Industrial Research Organization, Canberra, Australia.

CC: F600; F200 AB: We describe here the biochemical characteristics of the hcf44 and hcf47 (high chlorophyll fluorescence) mutants of maize (Zea mays L.). Both mutants were sensitive to high light intensities, exhibiting reduced growth and fluorescence intensity. Electron transport through the mutants' photosystem (PS)I and PsII reaction centers was reduced and NADP+ photoreduction was absent. Western analysis revealed that the hcf44 mutant was missing some or all of the PsaC, PsaD, and PsaE polypeptides of the PSI reaction center, and reverse transcriptase-polymerase chain reaction demonstrated that this loss was the result of a posttranscriptional event. The hcf47 mutant had reduced levels of many PSI and PSII polypeptides. These data indicate a possible defect in the synthesis or assembly of the PsaC subunit in the hcf44 mutant, whereas the hcf47 mutant may have a more general defect in the biogenesis of photosynthetic membranes. Our results demonstrate the coordinated assembly of the peripheral proteins into the PSI complexes of higher plants and demonstrate the in vivo requirement of PsaC, PsaD, and PsaE subunits for the function of PSI in higher plants.

CC: F600 AB: We examined the mechanism of synthesis in vitro of (1 leads to 3),(1 leads to 4)beta-D-glucan (beta-glucan), a growth-specific cell wall polysaccharide found in grasses and cereals. beta-Glucan is composed primarily of cellotriosyl and cellotetraosyl units linked by single (1 leads to 3)beta-linkages. The ratio of cellotriosyl and cellotetraosyl units in the native polymer is strictly controlled at between 2 and 3 in all grasses, whereas the ratios of these units in beta-glucan formed in vitro vary from 1.5 with 5 micrometer UDP-glucose (Glc) to over 11 with 30 mM substrate. These results support a model in which three sites of glycosyl transfer occur within the synthase complex to produce the cellobiosyl-(1 leads to 3)-D-glucosyl units. We propose that failure to fill one of the sites results in the iterative addition of one or more cellobiosyl units to produce the longer cellodextrin units in the polymer. Variations in the UDP-Glc concentration in excised maize (Zea mays) coleoptiles did not result in wide variations in the ratios of cellotriosyl and cellotetraosyl units in beta-glucan synthesized in vivo, indicating that other factors control delivery of UDP-Glc to the synthase. In maize sucrose synthase is enriched in Golgi membranes and plasma membranes and may be involved in the control of substrate delivery to beta-glucan synthase and cellulose synthase.

ID: protein-bodies. CC: F600; F200 AB: Saline-soluble glycinins and insoluble glutelins are the major storage proteins in soybean (Glycine max) and rice (Oryza sativa), respectively. In spite of their differences in solubility properties, both proteins are members of the 11S globulin gene family based on their similarities in primary sequences and processing of the coded protein. Wild-type and methionine-modified glycinin coding sequences were expressed in transgenic rice plants under the control of the rice glutelin GluB-1 promoter. Glycinins were specifically synthesized in the endosperm tissue and co-localized with glutelins in type II protein bodies. They assembled into 7S and 11S species, similar to what was observed in developing soybean seeds. This pattern was quite different from that displayed by the rice glutelins in untransformed plants, in which processed subunits sedimenting at 2S were apparent. In glycinin-expressing transgenic plants, however, glutelins were observed sedimenting at 7S and 11S with lesser amounts in the 2S region. A portion of the glycinins was also found associated in the insoluble glutelin fraction. Renaturation experiments suggested that the hybrid glycinin-glutelin oligomers were formed through specific interactions. Overall, these results indicate that despite significant differences in the assembly of soybean glycinin and rice glutelin, both proteins can assemble with each other to form soluble hexameric oligomers or insoluble aggregates.

Similarly, mRNAs for these proteins peak during endosperm development of Avena fatua (wild oat) and are later degraded. However, during late maturation of A.fatua seeds, populations of mRNA fragments shorter than the intact transcripts accumulate as the full-length transcripts decline in abundance. The smaller RNA molecules, which are apparently long-lived decay intermediates, are derived randomly from the entire transcripts and are most likely not generated by cleavage at precisely defined sites. Other A. fatua endosperm mRNAs that are degraded during late seed development, such as those for ADP glucose pyrophosphorylase and starch synthase, do not produce detectable decay intermediates. Decay intermediates of AV1 and Z1 mRNAs persist at high levels during late seed development of two other undomesticated oat species, Avena strigosa and Avena barbata. The persistence of decay intermediates for these endosperm mRNAs in wild grass species may represent a model system for studying RNA decay process in plant tissues.

CC: F200; F600 AB: We have used differential display to detect altering mRNA levels in response to desiccation and rehydration in leaves of the desiccation tolerant grass Sporobolus stapfianus. One of the RT-PCR products identified was used to isolate a cDNA of 999 bp which encodes a protein of 210 amino acids (predicted size 23 kDa). This protein displays considerable sequence similarity to mammalian and plant Rab2, a small GTP-binding protein, possessing several conserved motifs common to these regulatory proteins. Sporobolus Rab2 was expressed in Escherichia coli yielding a protein with an apparent molecular mass of ca. 30 kDa which was shown to have the ability to bind GTP. Rab2 transcript accumulated early in response to a decrease in relative water content (RWC) and remained high even in dried leaves. Rehydration of desiccated leaves resulted in a decrease in levels within 3 h of rewetting, with a brief increase at ca. 12 h. Accumulation of Rab2 transcript was also evident during drying and rehydration of the roots of S. stapfianus, as well as in leaves of the desiccation-sensitive grass Sporobolus pyramidalis. Earlier work on S. stapfianus concluded that the plant hormone ABA has little effect on inducing desiccation tolerance, however Rab2 transcript does exhibit a small increase in accumulation in response to exogenous ABA. A possible role for Rab2 with respect to desiccation tolerance and damage repair is discussed. XAU: Plant Stress and Water Conservation Laboratory, USDA ARS, Lubbock, TX.

CC: F200; F833 AB: Geminiviruses encode a few proteins and depend on cellular factors to complete their replicative cycle. As a way to understand geminivirus-host interactions, we have searched for cellular proteins which interact with viral proteins. By using the yeast two-hybrid technology and the wheat dwarf geminivirus (WDV) RepA protein as a bait, we have isolated a family of proteins which we termed GRAB (for Geminivirus Rep A-binding). We report here the molecular characterization of two members, GRAB1 and GRAB2. We have found that the 37 C-terminal amino acids of RepA are required for interaction with GRAB proteins. This region contains residues conserved in an equivalent region of the RepA proteins encoded by other viruses of the WDV subgroup. The N-terminal domain of GRAB proteins is necessary and sufficient to interact with WDV RepA. GRAB proteins contain an unique acidic C-terminal domain while their N-terminal domain, of ca. 170 amino acids, are highly conserved in all of them. Interestingly, this conserved N-terminal domain of GRAB proteins exhibits a significant amino acid homology to the NAC domain present in proteins involved in plant development and senescence. GRAB1 and GRAB2 mRNAs are present in cultured cells and roots but are barely detectable in leaves. GRAB expression inhibits WDV DNA replication in cultured wheat cells. Our studies highlight the importance that the pathway(s) mediated by GRAB proteins, as well as by other NAC domain-containing proteins, might have on geminivirus DNA replication in connection to plant growth, development and senescence pathways.

(2n = 2x = 18), was identified cytologically from progenies derived from crosses between autotriploids (2n = 3x = 27) and their diploid counterparts. Five autotriploid plants were identified from 2100 seedlings derived from 4x-2x crosses; the reciprocal crosses (2x-4x) failed to produce autotriploids. Autotriploids grew vigorously and were morphologically very similar to diploids. The primary trisomics (2n = 2x = 19) constituted approximately equal to 32.5% of the total progeny from the 3x-2x crosses, whereas 59.8% of the descendants were aneuploids with chromosome numbers ranging from 20 (double trisomics and tetrasomics) to 37 (2n = 4x + 1; or autotetraploid with one additional chromosome). The nine primary trisomics identified were self-fertile; seven had characteristic morphology, whereas trisomics VIII and IX resembled the disomics. The seed set for trisomic V was the lowest (20%), and trisomic VIII the highest (74%). Other aneuploids with 20 or more somatic chromosomes were either self-sterile or partially fertile with various, but low, levels of seed set. Each of the primary trisomics showed its unique transmission rate when self-pollinated; trisomic IX had the highest (45.8%), whereas trisomic V had the lowest (19.6%) transmission rate.

CC: F200; F120 AB: Variability for desirable alleles within elite breeding populations is a requirement for long-term genetic improvement. Changes in genetic diversity were evaluated in a recurrent selection programme for enhanced grain yield in oat, Avena sativa L., using coefficient of parentage (r(p)) and restriction fragment length polymorphism (RFLP) based genetic similarity (s) estimates. Both r(p) and s increased during seven cycles of recurrent selection, indicating a reduction in the level of genetic diversity within the population. The relationship between genetic diversity and agronomic performance was also examined. Genetic similarity measures were poor predictors of the near-homozygous progeny performance and general and specific combining ability effects for three agronomic traits in the recurrent selection programme. In addition, there was no apparent trend for preferential selection of progeny from either more similar or more diverse parents within a given cycle of selection. The overall reduction in genetic diversity in this population has not affected selection response for grain yield. Variability remaining at important loci or de novo variation are possible explanations for the continued selection progress. XAU: Agriculture and Agri-Food Canada, Ottawa, Ontario, Canada.

Our aim is to study the genetic basis of barley resistance to leaf stripe. A qualitatively acting resistance factor has been identified in the cultivar 'Vada' and the partial resistance of the cultivar 'Proctor' to a P. graminea isolate have been demonstrated to be dominated by a major quantitative trait locus (QTL), mapped on barley chromosome 1. Map colinearity between the leaf stripe 'Proctor' resistance QTLs, 'Vada' resistance to leaf stripe and other disease resistance loci have been investigated in this work using molecular markers. Moreover, since inoculation of barley rootlets by the fungus had been shown to induce the accumulation of several PR (pathogen-related) mRNA families, seven barley PR genes have been mapped as RFLPs, and one assigned to a chromosome arm via ditelosomic analysis to verify possible map associations between the known leaf stripe resistance loci, resistance loci towards other seed-borne pathogens and defense gene loci.

CC: F200; X200 AB: Multi-environment trials (METs) are used in plant breeding programmes to evaluate genotypes (lines/families) as a basis for selection on expected performance (yield and/or quality) in a target population of environments (TPE). When a large component of the genotype-environment (G x E) interactions results from crossover interactions, samples of environments in METs that deviate from the TPE provide a suboptimal basis for selection of genotypes on performance expected in the TPE. To adjust for the negative effects of these deviations, a selection strategy that weights the data from the MET according to their expected frequency of occurrence in the TPE (i.e. a weighted selection strategy) was investigated. Computer simulation methodology was used to obtain preliminary information on the weighted selection strategy and compare it to the traditional unweighted selection strategy for a range of MET scenarios and G x E interaction models. The evaluation of the weighted selection strategy was conducted in context with the germplasm enhancement programme (GEP) of the Northern Wheat Improvement Programme in Australia. The results indicated that when the environments sampled in the MET matched those expected in the TPE, the unweighted and weighted selection strategies achieved a similar response to selection in the TPE. However, when the environments sampled in the MET did not match the expectations in the TPE and a large component of the G x E interactions resulted from crossover interactions, the weighted selection strategy achieved a greater response to selection in the TPE. The advantage of the weighted strategy increased as the amount of crossover G x E interaction increased. or fewer environments were sampled in the METs.

CC: F600 AB: The purpose of the present work was to evaluate both oxidative stress and the antioxidant response system in leaves from wheat (Triticum aestivum cv. Buck Poncho) subjected sequentially to drought and watering. Drought was imposed by withholding water until soil water potential reached -2.0 MPa and maintained under those conditions for 24 h. DCFDA oxidation by wheat leaves was not significantly affected by drought, but watering led to an approximately 2-fold increase in DCFDA oxidation rate. However, no significant effect either on lipid radical content or on hydroperoxide content was measured after drought and drought followed by watering. Microsomes isolated from leaves exposed to drought, and from leaves exposed to drought followed by watering, generated a significantly higher amount of hydroxyl radical as compared to microsomes isolated from control leaves, suggesting a higher production of hydroxyl radical in the cellular water-soluble phase, after drought and watering as compared to control values. The content of alpha-tocopherol in wheat leaves was increased 2.4-fold after drought and beta-carotene content was increased by 2.6-fold after drought. Hydration lowered lipid-soluble antioxidant content to control values. Total thiol content was increased by 70% after drought, and watering did not significantly alter the enhanced values. Drought decreased by 28.5% the content of reduced ascorbic acid. Taken as a whole, active species formed at wheat membranes after exposure to moderate water stress, are efficiently removed upon rehydration by reaction with an increased content of alpha-tocopherol and beta-carotene. Moreover, a co-ordinated response involving. glutathione reductase activity, thiols and ascorbic acid is triggered to limit free radical dependent effects.

CC: F600 AB: With the aim of determining the level at which ageing exerts its effect on the expression of alpha-amylase, GA3 regulation of alpha-amylase production was studied in isolated aleurone layers from aged wheat seeds. GA3-induced a-amylase activity was lower in the tissue from aged seeds than in controls. However, the proportion of 35S-methionine incorporated into alpha-amylase was higher in the aged than in control tissue. The pattern of alpha-amylase isoforms was resolved by isoelectric focusing and showed that two isogroups were present with the activity of the high-pl isogroup being higher in the control than in the aged lot. These apparently contradictory results may be explained in terms of differences in isozyme expression. Studies on the expression of alpha-amylase genes indicated a reduction in the level of high-Pl mRNA in aged tissue. Dose-response curves showed lower GA3-responsiveness of aleurone layers from aged seeds as compared to the controls. From these results, it is proposed that the diminished capacity of alpha-amylase production in aleurone from aged seeds is apparently due to a decrease in the expression of the high-pl alpha-amylase genes, and this reduction is associated with a decrease in the response to GA3.

ID: protein-quantity-loci. CC: F200; F600 AB: The proteome is emerging as an important concept of the post-genome era. Powerful nucleic acid approaches (EST, DNA chips, etc.) are still limited because DNA sequences and mRNA levels are not sufficient to predict the structure, function, amount, and activity of the proteins in the cell. The proteome can now be subjected to large-scale analysis, owing to spectacular progress in the techniques of identification of proteins excised from two-dimensional (2-D) gels. In addition, computer-based analysis of 2-D gels makes it possible to quantify the protein spot intensities, which are commonly genetically variable. The loci controlling these variations may be mapped on the genome (PQLs, Protein Quantity Loci). Beyond the interest for regulatory genetics and molecular biology, the PQL methodology can provide an additional tool for the difficult task of identifying QTLs (Quantitative Trait Loci), in the context of the candidate gene approach. The PQL methodology is presented with the example of the phosphoglycerate mutase variations in maize, and the candidate gene/protein approach is illustrated for traits responsive to drought stress.

CC: F200; F600 AB: Studying the heterogeneity in variation of gene frequency among populations or between generations may be a possible way to detect genomic regions experiencing selection. In order to evaluate this approach, RFLP markers were used to compare the allelic frequencies in wheat populations that had been submitted to natural selection. In 1984, samples of two composite cross populations were distributed in the French network for dynamic management of genetic resources. Since then, all the sub-populations have been cultivated in the same sites with no human selection. The strong differentiation between populations found for agro-morphological traits (earliness, resistance to pathogens, ...) provided evidence of their adaptation to local conditions. The two initial populations and six derived sub-populations cultivated for 10 years in four contrasted sites were studied with RFLP markers. Differentiation between sub-populations based on RFLP diversity was highly significant. Variations of allelic frequencies of the 30 loci scored were found to be much greater than expected under genetic drift only. This led us to conclude that selection greatly influenced the evolution of the populations. Some of the loci clearly presented a higher differentiation than the others. This might indicate that they were genetically linked to other loci polymorphic in the populations and involved in adaptation. However, the effect of one selected gene on a marker, even located very close to the gene, could not be predicted with certainty. Hence, though the populations were predominantly selfing, it seems that initial linkage disequilibriums between markers and selected genes were not strong enough to control closely the evolution of. allelic fequencies at the markers.

CC: F120; M120 AB: Rice (paddy) and fish yields in concurrent, direct-seeded culture were investigated at the Co Do station located in the Mekong Delta, Vietnam. Three different rice seeding rates (100, 200 and 300 kg ha(-1)) were used in the absence or presence of fish (Oreochromis niloticus (all male). Puntius gonionotus, and Cyprinus carpio). Significantly (P < 0.05) higher paddy and fish yields were obtained at the lowest rice seeding rate. No significant effect of the rice seeding rate on aquatic weed biomass was found, whereas water temperature, dissolved oxygen concentration and pH were significantly (P < 0.05) higher at 100 kg rice seed ha(-1) . The presence of fish resulted in a significant (P < 0.05) reduction of aquatic weed biomass, and significantly (P < 0.05) lower dissolved oxygen and PO(4) concentrations, and higher chlorophyll-a levels in the pond water. Analysis of the results indicated that the effect of rice seeding rate on fish production was most likely to be related to a 'growth effect' resulting from increased availability of oxygen and food. Paddy yields at high seeding densities were affected by mutual shading. A further reduction of rice seeding rate may be feasible for rice-fish farmers, given their limited possibilities for weed control through land preparation (field levelling) and water management.

CC: F600; F200; F841 AB: We analyzed antioxidative defenses, photosynthesis, and pigments (especially xanthophyll-cycle components) in two wheat (Triticum durum Desf.) cultivars, Adamello and Ofanto, during dehydration and rehydration to determine the difference in their sensitivities to drought and to elucidate the role of different protective mechanisms against oxidative stress. Drought caused a more pronounced inhibition in growth and photosynthetic rates in the more sensitive cv Adamello compared with the relatively tolerant cv Ofanto. During dehydration the glutathione content decreased in both wheat cultivars, but only cv Adamello showed a significant increase in glutathione reductase and hydrogen peroxide-glutathione peroxidase activities. The activation states of two sulfhydryl-containing chloroplast enzymes, NADP(+)-dependent glyceraldehyde-3-phosphate dehydrogenase and fructose-1,6-bisphosphatase, were maintained at control levels during dehydration and rehydration in both cultivars. This indicates that the defense systems involved are efficient in the protection of sulfhydryl groups against oxidation. Drought did not cause significant effects on lipid peroxidation. Upon dehydration, a decline in chlorophyll a, lutein, neoxanthin, and beta-carotene contents, and an increase in the pool of de-epoxidized xanthophyll cycle components (i.e. zeaxanthin and antheraxanthin), were evident only in cv Adamello. Accordingly, after exposure to drought, cv Adamello showed a larger reduction in the actual photosystem II photochemical efficiency and a higher increase in nonradiative energy dissipation than cv Ofanto. Although differences in zeaxanthin content were not sufficient to explain the difference in drought. tolerance between the two cultivars, zeaxanthin formation may be relevant in avoiding irreversible damage to photosystem II in the more sensitive cultivar.

ID: acc-oxidase. CC: F600; F200 AB: Mutant sorghum (Sorghum bicolor [L.] Moench) deficient in functional phytochrome B exhibits reduced photoperiodic sensitivity and constitutively expresses a shade-avoidance phenotype. Under relatively bright, high red:far-red light, ethylene production by seedlings of wild-type and phytochrome B-mutant cultivars progresses through cycles in a circadian rhythm; however, the phytochrome B mutant produces ethylene peaks with approximately 10 times the amplitude of the wild type. Time-course northern blots show that the mutant's abundance of the 1-aminocyclopropane-1-carboxylic acid (ACC) oxidase mRNA SbACO2 is cyclic and is commensurate with ethylene production, and that ACC oxidase activity follows the same pattern. Both SbACO2 abundance and ACC oxidase activity in the wild-type plant are very low under this regimen. ACC levels in the two cultivars did not demonstrate fluctuations coincident with the ethylene produced. Simulated shading caused the wild-type plant to mimic the phenotype of the mutant and to produce high amplitude rhythms of ethylene evolution. The circadian feature of the ethylene cycle is conditionally present in the mutant and absent in the wild-type plant under simulated shading. SbACO2 abundance in both cultivars demonstrates a high-amplitude diurnal cycle under these conditions; however, ACC oxidase activity, although elevated, does not exhibit a clear rhythm correlated with ethylene production. ACC levels in both cultivars show fluctuations corresponding to the ethylene rhythm previously observed. It appears that at least two separate mechanisms may be involved in generating high-amplitude ethylene rhythms in sorghum, one in response to the loss of phytochrome. B function and another in response to shading. XAU: Texas A&M University, College Station, TX.

CC: F600; F841 AB: Using monoclonal tubulin and actin antibodies, Al-mediated alterations to microtubules (MTs) and actin microfilaments (MFs) were shown to be most prominent in cells of the distal part of the transition zone (DTZ) of an Al-sensitive maize (Zea mays L.) cultivar. An early response to Al (1 h, 90 micromolar) was the depletion of MTs in cells of the DTZ, specifically in the outermost cortical cell file. However, no prominent changes to the MT cytoskeleton were found in elongating cells treated with Al for 1 h in spite of severe inhibition of root elongation. Al-induced early alterations to actin MFs were less dramatic and consisted of increased actin fluorescence of partially disintegrated MF arrays in cells of the DTZ. These tissue- and development-specific alterations to the cytoskeleton were preceded by and/or coincided with Al-induced depolarization of the plasma membrane and with callose formation, particularly in the outer cortex cells of the DTZ. Longer Al supplies (> 6 h) led to progressive enhancements of lesions to the MT cytoskeleton in the epidermis and two to three outer cortex cell files. Our data show that the cytoskeleton in the cells of the DTZ is especially sensitive to Al, consistent with the recently proposed specific Al sensitivity of this unique, apical maize root zone.

CC: F600; F500 AB: Many reports have shown that plant growth and yield is superior on mixtures of NO(3)(-) and NH(4)(+) compared with provision of either N source alone. Despite its clear practical importance, the nature of this N-source synergism at the cellular level is poorly understood. In the present study we have used the technique of compartmental analysis by efflux and the radiotracer (13)N to measure cellular turnover kinetics, patterns of flux partitioning, and cytosolic pool sizes of both NO(3)(-) and NH(4)(+) in seedling roots of rice (Oryza sativa L. cv IR72), supplied simultaneously with the two N sources. We show that plasma membrane fluxes for NH(4)(+), cytosolic NH(4)(+) accumulation, and NH(4)(+) metabolism are enhanced by the presence of NO(3)(-), whereas NO(3)(-) fluxes, accumulation, and acquisition and N translocation to the shoot with dual N-source provision are substantially larger than when NO(3)(-) or NH(4)(+) is provided alone at identical N concentrations.
