Abstract
Based on a 20-year long-term experiment on fertilizers in fixed plots (Jiangsu, China), three winter wheat ( Triticum aestivum ) cultivars, Xuzhou 25, Xuzhou 26 and Yan 2801, were used to investigate the effects of different fertilizer combinations on cell membrane lipid peroxidation, photosynthetic rate, glutamine synthetase [glutamate-ammonia ligase] (GS) activity in flag leaf at active grain filling stage, and grain yield and protein content at maturity. In flag leaf, membrane lipid peroxidation was lower, photosynthetic rate was higher and grain yield was consequently higher in the treatments of combined application of organic and inorganic fertilizers (TMI) than that in corresponding treatments of only inorganic fertilizer applied (TI). Among treatments of TMI or of TI, grain yield increased with increment of the application kinds on the combination of N, P and K fertilizers, as consistent with decreasing membrane lipid peroxidation and increasing photosynthetic rate in flag leaf. When only N and K fertilizers were applied, cell membrane lipid peroxidation in flag leaf increased greatly while photosynthetic rate decreased obviously, thus resulting in very low grain yield. No significant correlations were observed between grain protein content and GS activity, or nitrogen content in flag leaf under different fertilization treatments
