Alterations in the photosynthetic characteristics of the grapevine cultivars Debina and Dichali in response to drought stress upon completion of the experiment. (A) Net photosynthetic rate (AN), (B) Stomatal conductance (gs), (C) Transpiration rate (E), (D) Intrinsic Water Use Efficiency (WUEi). C, control plants; T, drought stress treatment. Different lowercase letters indicate differences at a significance level of 0.05.
