According to this, neither Tleaf nor Tleaf–air showed similar values over the experiment in the FI treatment. This finding agrees with the high variability of data recorded for gas-exchange measurements. In this sense, although the Tleaf values found in this treatment were significantly lower than at the beginning of the experiment 9 at 14 DAT; this treatment offered Tleaf–air values lower than those reached the first day (almost 6◦C lower than 0 DAT(Fig. 3).
