Changes in skin color and pigments in non-red skinned cultivars ‘Granny Smith’ and ‘Golden Delicious’ after bag removal. a: Color development in apple skin of the two cultivars 0–10 days after bag removal; b: Changes in color parameter a* value, cyanidin3-galactoside content, and chlorophyll content in fruit skin of two apple cultivars after bag removal. 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)
