Changes of the (A) crop water stress index (CWSI), and (B) stomatal conductance index (I_G), calculated from leaves of Coffea canephora cv. Conilon Clone 153 (CL153) and C 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=5) express significant differences among temperature treatments for the same water level (A–D), or among water availability levels for each temperature treatment (a, b), always separately for each cultivar.
