  1. Amax, light- saturated photosynthetic rate; LCP, light compensate point; LSP, light saturate point; Rd, dark respiration rate; Vcmax, maximum rate of RuBP carboxylation; Gs, stomatal conductance; Ci, intercellur CO2 concentration; Tr, transpiration rate; WUE, photosynthetic water use efficiency. Different letters in the same row indicate statistical difference (p < 0.05).
