Effect of 5-aza-2′-deoxycytidine (5-aza-dC) treatment on pigments in ‘Granny Smith’ and ‘Golden Delicious’ fruit skins after bag removal. a: Color changes in apple skin of the two cultivars after 5-aza-dC treatment. b: Changes in color parameter a*, cyanidin3-galactoside content, and chlorophyll content in fruit skin of two apple cultivars after 5-aza-dC treatment. Data represent means ± standard deviation of four replicate samples. Different lower case letters indicate significant differences by Tukey’s multiple range test (p < 0.05), and ns indicates not significant
