Gas exchange parameters during the experimental period: (A) net photosynthetic rate; (B) transpiration rate; (C) stomatal conductance; (D) water use efficiency (mean ± SD). Different letters denote statistically significant differences among treatments at each experimental day (p ≤ 0.05). An, rate of net photosynthesis; Tr, transpiration rate; gs, stomatal conductance; WUE, instantaneous water use efficiency.
