The effects of sunlight exposure treatments on volatile compounds. a Concentrations of free and glycosylated benzenoid, C6 alcohol, monoterpene and norisoprenoid in the exposed and control ripening berries. b Concentrations of free-form C6 aldehyde and C9 compounds in the exposed and control ripening berries. c Score plot and loading plot of principal components 1 and 2 for the measured variables. Different letters indicate significant differences (P = 0.05). d Hierarchical cluster analysis of all variables in the treatments and control. Volatile compounds are grouped into five clusters according to the responses to the treatments. Boxes with bold margins indicate significant differences (P = 0.05) between the treatment and control at ripening stage.
