  1. Net photosynthetic rate (Pn), stomatal conductance (g s ), estimated leaf chlorophyll content, total (primary and secondary) leaf area growth, shoot growth and total percentage of flower drop average values are reported. **, *** mean that the treatments are significantly different at p-value ≤ 0.01 or ≤0.001 (ANOVA). Within each column, different letters indicate significant differences among treatments according to Tukey’s HSD test (p-value ≤ 0.05)
