Changes in the leaf maximum apparent activities of (A) superoxide dismutase (Cu,Zn-SOD), (B) ascorbate peroxidase (APX), and (C) glutathione reductase (GR) from chloroplast, and (D) cellular catalase (CAT) in Coffea canephora cv. Conilon Clone 153 (CL153) and Coffea arabica cv. Icatu plants under well-watered conditions (WW) or submitted to severe water deficit (SWD), followed by a gradual temperature increase from (25/20°C, day/night), to 42/30°C, and a recovery period of 14 days (Rec14). For each parameter, different letters after the mean values ± SE (n=4) express significant differences among temperature treatments for the same water level (A–E), or among water availability levels for each temperature treatment (a, b), always separately for each cultivar.
