Enzymatic activities in tolerant (RB92579) and susceptible (SP80–3280) sugarcane plant exposed to different water deficit regimes. a - NADP-ME; b - NAD-ME; c - PEPCK; d - AspAT; e - AlaAT. Different upper case and lower letters indicate statistical differences between cultivars in each treatment and between water deficit treatments (control, moderate, severe and recovery) for each cultivar, respectively, according to Tukey test (P < 0.05). Values presented as mean ± SE (n = 3) and expressed in μmol min^− 1 mg^− 1 Chl
