Fig. 2From: Interactive effects of nitrogen and potassium on photosynthesis and photosynthetic nitrogen allocation of rice leavesInteractive effects of nitrogen and potassium on leaf N allocation by morphology. Nstr represents structural N, Npsn represents photosynthetic N, Nrep represents respiratory N, Nstore represents storage N. The number out of the bracket represents the absolute N content (g m− 2) of different morphologies. The number in the bracket represents the relative content (%)Back to article page
