Hydrogen peroxide (H2O2) and malondialdehyde (MDA) levels and polyphenol oxidase (PPO) activity weremeasured in ‘Fuji’ apples with different susceptibilities to the development of superficial scald during storage at 0and 20°C. Both scald incidence and severity increased gradually in the cold and the symptoms became apparent inthe fruits with an early, middle, and late harvest after 12, 15, and 21 weeks storage, respectively. Early harvestfruits had the highest scald incidence and severity as well as H2O2 and MDA contents, while late harvest had thelowest. The H2O2 and MDA levels increased, while PPO activity remained constant during storage at 0°C. All fruitsshowed a rapid increase in scald incidence and severity after warming, especially at the first 4 days, when H2O2 andMDA levels and PPO activities also increased. The H2O2 and MDA levels in scald-free tissues in late harvest fruitswere lower initially but became higher in the scald tissues after warming for 4 days. The PPO activities were equalin both tissues. These results indicated that mature fruits were relatively resistant to scald, and that scald symptomdevelopment was highly dependent on the accumulations of H2O2 and MDA during cold storage, but PPO activitywas less important.
