摘要
Peach fruits (Amygdalus persica cv. Okubao) were stored in air, controlled atmospheres (CA) of 5% O-2 plus 5% CO2, or CA with high O-2 concentration (70% O-2 Plus 0% CO2 for 15 days, then in CA with 5% O-2 plus 5% CO2) at 0 degreesC, to determine the effects of different O-2 and CO2 atmospheres on the activities of lipoxygenase (LOX), peroxidase (POD), superoxide dismutase (SOD) and catalase (CAT), as well as malondialdehyde (MDA) content and membrane integrity during storage periods with or without 3 days of post-storage ripening at '20 degreesC. SOD, CAT and POD activities of the fruits stored in air markedly decreased during the first 30 days of storage, while LOX activity increased after 15 days. CA (5% O-2 plus 5% CO2) reduced chilling injury, and delayed the reduction of SOD, CAT and POD activities compared to the control. CA with high O-2 treatment induced SOD and CAT activities and maintained membrane integrity, but no significant effect on alleviating chilling injury was found compared to CA storage. The results indicated that the decrease of SOD and CAT might contribute to the development of chilling injury in peach fruits. (C) 2004 Elsevier Ltd. All rights reserved.
