  1. Net photosynthetic rate (Pn) and stomatal conductance (g s ) after shade period, and bunch weight, number of berries, rachis length and bunch compactness average values are reported. ns, **, *** mean that the treatments are not significantly different, 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)
