Tleaf response was contrary to leaf stomatal conductance and leaf net photosynthetic rates (Fig. 3, Table 2). At the beginning of the study (0 DAT), Tleaf ranged between a minimum of 23.6 ± 0.4◦C in FI and a maximum of 24.2 ± 0.3◦C in PRD.Tleaf in RDI and NI was 24.2 ± 0.3 and 24.1 ± 0.5◦C, respectively. At 9 DAT, when photosynthetic rates of NI plants were about half of FI, we found significant differences were found between NI (41.2 ± 0.3◦C) and PRD (40.3 ± 0.4◦C) in comparison to FI (35.6 ± 0.5◦C) and RDI (36.4 ± 0.8◦C) (Fig. 3A). Tleaf values for FI increased 5.6◦C in relation to the beginning of the experiment, whereas PRD values rose 4.7◦C. At maximum stress(14 DAT (Fig. 3A), Tleaf values of NI plants were 35.3 ± 0.4◦C,showing significant differences as compared to the remaining treatments, which showed values of 28.5 ± 0.7◦C, 32.1 ± 0.5◦Cand 33.5 ± 0.6◦C in the case of FI, PRD and RDI plants, respectively.
