Effects of genotype and nitrogen fertilizer on winter wheat photosynthetic parameters and leaf morphogenesis during later growth

  • 摘要: 田间试验研究不施N和施N(90kg/hm2)条件下“NR9405”、“9430”、“偃师9号”、“小偃6号”、“陕229”、“西农2208”、“矮丰3号”和“商188”等8种不同基因型冬小麦中后期生理特性及其叶片形态的差异结果表明,抽穗期倒二叶和灌浆期旗叶的净光合速率、气孔导度、蒸腾速率及瞬时水分利用效率在不同基因型间存在显著差异,施N仅能显著降低抽穗期倒二叶的蒸腾速率,而对功能叶的其他生理指标无明显影响。小麦成熟期旗叶和倒二叶的长度、宽度及叶面积在不同基因型间也存在极显著差异,施 N对这些叶片形态指标有极显著地促进作用,基因型和N肥同时影响灌浆期旗叶的SPAD值,而叶片衰老指数主要受基因型调控。总体上看,冬小麦叶片形态指标同时受施N和基因型影响 ,而生理指标主要受基因型影响,N肥的影响相对较小。
    Abstract: A field experiment was carried out in the south part of loess plateau on the soil with 632mm annual precipitation and eight winter wheat varieties, “NR9405”,“9430”,“Yanshi No.9”,“Xiaoyan No.6”,“Shan229”,“Xinong2208”,“Aifeng No.3”and “Shang188” were used as indicators to study the effects of genotype and nitrogen fertilizer on winter wheat photosynthetic parameters and leaf morphogenesis. The results show that genotypes differ significantly in photosynthetic rate (Pn), stomatic conductance (Gs), transpiration rate (E) and short-time water use efficiency (WUEst) of second leaf at booting and flag leaf at filling. The application of nitrogen fertilizer can significantly decrease the transpiration rate (E) of second leaf at booting, but it has no significantly effect on any other physiological parameters both at booting and at filling. Genotypes differ significantly in the length, width and area of second leaf and flag leaf, these leaf morphogenesis traits are increased significantly by the application of nitrogen fertilizer. During the grain-filling, the flag leaf SPAD is affected by genotype and nitrogen fertilizer and the leaf senescence index is affected only by genotype, not by nitrogen fertilization.
