Fig. 3From: Nitrogen deficiency regulates premature senescence by modulating flag leaf function, ROS homeostasis, and intercellular sugar concentration in rice during grain fillingCarbon and nitrogen translocation rate in the flag leaves of psf mutant and its wildtype under different nitrogen supply. Data are means ± SD (n=3). Different letters indicate a significant difference between N treatments at p < 0.05 least significant difference (LSD). N translocation efficiency (NTE) = (nitrogen translocation/leaf N content at anthesis) × 100. NSC translocation rate = [NSCs in leaf at the heading stage − NSCs residue of the leaf at the harvest stage]/NSCs in leaf at the heading stage × 100Back to article page
