The biochemical changes related to scald including a-farnesene, conjugated
trienols (CTols), antioxidants, antioxidant enzyme activities were monitored among separated blushed
and shaded peels of unbagged fruit as well as the whole peel of bagged fruit. In unbagged fruit, scald
symptom was restricted to shaded peel; while there was no difference in a-farnesene between blushed
and shaded peels, CTols increased significantly in shaded peel along with scald development after
3 months storage
