Fig. 5From: Nitrogen deficiency regulates premature senescence by modulating flag leaf function, ROS homeostasis, and intercellular sugar concentration in rice during grain fillingImpact of N deficiency/overfeeding on ROS bust and membrane integrity in the flag leaves of wildtype and psf mutant during senescence: A, B H2O2 accumulation, C, D NBT staining, E, F O2 concentration, G, H DAB staining, and I, J relative conductivity. Data are means of ±SD (n=3), different letters indicate a significant difference between treatments at a particular sampling period (P < 0.05) LSDBack to article page
