Highlights • Genetic differences in 30 wheat cultivars in flag-leaf photosynthesis rate were correlated with differences in grain yield under high N conditions.• Post-anthesis flag-leaf photosynthesis rate was positively associated with pre-anthesis N uptake under high N conditions.• Genetic differences in Normalized Difference Vegetation Index during late grain filling were associated with differences in grain yield under high N and low N conditions.• Cultivar grain protein deviation was associated with post-anthesis N uptake under N limitation.

印度小麦品种中氮分配和再利用与叶片衰老、籽粒产量和蛋白质浓度的关系


研究亮点• 30个小麦品种旗叶光合速率遗传差异与高氮条件下籽粒产量差异相关。• 高氮条件下花后旗叶光合速率与花前吸氮量正相关。•灌浆后期归一化植被指数的遗传差异与高氮和低氮条件下的籽粒产量差异相关。• 品种籽粒蛋白质偏差与氮限制下花后氮吸收相关。
