  1. Note: Rate of changes (%) were displayed by mean ± S.E., n = 5; p values indicated the significance of the difference between LS1 and LS2 (t-test). Pn, net photosynthesis rate; Gs, stomatal conductance; Fv/Fm, potential efficiency of primary conversion of light energy of PSII; Fv/Fo, the ratio of variable fluorescence to initial fluorescence.
