1 Compounds were quantified at 320 nm. 2 Values represent the mean of three replicates ± standard error of the mean. 3 Different letters in the same column indicate statistical difference in the concentration of each compound between treatments using the least significant difference (LSD) test (p < 0.05). 4 Asterisks indicate that main effects and interactions are significantly different by analyses of variance (ANOVA). NS—non significant, * p < 0.05, ** p < 0.01, *** p < 0.001. Abbreviations: dry weight (DW); fruit without UVB light treatment (UV-); fruit treated with UVB (6.4 W·m−2) light for 15 min (UV+); ND (not detected).
