Photosynthetic characteristics and chlorophyll fluorescence parameter changes in drought-treated P. lactiflora and the Control. (a) Photosynthetic characteristics. (b) Chlorophyll fluorescence parameters. Values represent the mean ± standard deviation (SD) and letters indicate significant differences according to Duncan’s multiple range test (P < 0.05). Pn, net photosynthesis rate; Tr, transpiration rate; Gs, stomatal conduction; Fo, minimal fluorescence; Fv, variable fluorescence; Fm, maximum fluorescence; Y(II), photosynthetic efficiency of photosystem II.
