采后适当失水处理对软枣猕猴桃20℃下生理生化变化的影响
Effects of appropriate dehydration treatment on physiology and biochemistry of Actinidia arguta during postharvest stored under 20 ℃
摘要
Abstract
[Objective]This study aimed at investigating the effecf of dehydration treatment on postharvest physiology of Actinidia arguta Sieb. et Zucc. [Method] The fruits were stored at room temperature(20± 0.5)℃ after dehydration treatment, and the dehydration rate was 2%, 4% and 6%, respectively. The effect of dehydration treatment on postharvest physiology of Actinidia arguta was discussed. [Result]The results demonstrated that appropriate dehydration could both restrain the respiration intensity of Actinidia arguta and postpone the peak time, and also could inhibite the release of ethylene, postpone the peak of ethylene and the arrival of climacteric. The peak valume was reduced by this treatment. Proper dehydration could reduce pectinase activity, and inhibit decomposition of pectin during the whole storage. This treatment maintained the fruit firmness and flavor, and therefore, the fruit maturation and aging process were delayed. Among the three dehydration rates, 4% of fruit dehydration had a significant performance. When the fruits treated with dehydration of 4% stored 10 days, the decay rate was 37.23%, which was significantly lower than that of the other treatment groups(P<0.05). [Conclusion]Thus the experiment indicated that dehydration rate of 4% had fairly good effects on the storage and fresh-keeping of Actinidia arguta.关键词
