The highest values of gs, An, and E were detected in FI plants,and the lowest in NI plants (Table 2). There was a gradual reduction in gs and An for the PRD treatment during the study. At9 DAT, a significant decrease was detected in An, from 14.3 to6.38 mol CO2m−2s−1, with a parallel decrease of gs(from 0.24to 0.07 mol H2O m−2s−1). Similarly, leaf transpiration fell from 4.1to 1.8 mmol H2O m−2s−1, with significant differences between FI and NI.
