Photosynthetic parameters of four Artemisia species subjected to soil drought stress. A, Net photosynthetic rate (a); E, transpiration rate (b); WUEi, instantaneous water use efficiency (c); Gs, stomatal conductance (d); Ls, stomatal limitation (e). CK control setup, DW drought stress. Different letters indicate significant difference at P < 0.05. Values are presented as mean ± SD, N = 6
