热处理对采后茄子果实冷害和活性氧代谢的影响
Effects of heat treatment on chilling injury and active oxygen metabolism of postharvest eggplant fruit
摘要
Abstract
The effects of hot air treatment at 45 'C for 24 h on chilling injury and active oxygen metabolism of posthar-vest eggplant fruit were studied. During fruit storage, chilling index (CD, membrane permeability, malondialdehyde (MDA), superoxide anions (Of ? ) production rate, activities of active oxygen scavenging enzymes such as superoxide dismutase (SOD), catalase (CAT) and ascorbate peroxidase (APX) were determined. Heat treatment restrained signifi-cantly the incidence of chilling injury of eggplant fruits, reduced O2-production rate, cell membrane permeability and MDA content, increased the activities of SOD,CAT and APX. The results showed that heat treatment can improve effec-tively active-oxygen-scavenging capacity of eggplant fruit during cold storage, induce the inhibition of lipid peroxidation, and enhance cold resistance of the fruit, thereby reduce the incidence of chilling injury.关键词
