FIGURE 5.
Photosynthetic and transpiration rates measured in 2016 (A,B, respectively) and 2017 (C,D, respectively) as affected by biostimulant applications (T0: immediately before spray; T1: 48 h after spray; T2: 96 h after spray). Asterisk (∗) and the pink rectangle in the background indicate the group of treatments that significantly differed from control according to Dunnett’s test (P < 0.05).
