棉花氮素利用效率动态调控机理的探讨
Exploring the mechanisms regulating the dynamics of nitrogen use efficiency in cotton
了解低氮供应条件下植物氮素利用效率的调控机理是提高作物生产力的关键。旨在阐明低氮(0.5mmol•L-1)和高氮(5.0mmol•L-1)条件下不同基因型棉花的形态、光合作用和生长发育对氮素吸收、同化和利用的潜在机理，选用了氮高效型(HM-2270、GH-Uhad)和氮低效型(Z-50、FH-444)棉花材料。HM-2270的根系和地上部干物质质量最大，而FH-444和Z-50的最低。HM-2270的叶面积、上表皮细胞面积、气孔密度和气孔指数最高…查看全部>>
Understanding the mechanisms of nitrogen(N) use efficiency in plants under low N supply is crucial to improve crop productivity. This study aimed to elucidate the potential mechanisms involved in N uptake, assimilation and its utilization associated with morphology, photosynthesis and growth of different cotton genotypes i.e. N-efficient(HM-2270,GH-Uhad) and N-inefficient(Z-50,FH-444) grown under low-N (0.5 mmol•L-') and high-N(5.0 mmol•L-1) conditions. HM-2…查看全部>>
