摘要

为了探究贮藏温度对软枣猕猴桃采后生理品质及抗氧化酶活性的影响,分别将软枣猕猴桃置于0、5和10 ℃下贮藏,测定其在贮藏过程中的相关指标。结果表明,与5和10 ℃相比,0 ℃贮藏显著抑制了软枣猕猴桃的褐变以及呼吸强度,保持了较高的果实硬度、维生素C(Vc)、谷胱甘肽(glutathione,GSH)和类黄酮含量,抑制了相对电导率、丙二醛(MDA)含量、过氧化物酶(POD)和多酚氧化酶(PPO)活性的增加,同时,保持了较高的超氧化物歧化酶(SOD)、过氧化氢酶(CAT)和谷胱甘肽还原酶(GR)活性。0 ℃条件下软枣猕猴桃没有发生冷害,该贮藏温度最有利于保持软枣猕猴桃的采后生理品质。

Abstract

This study aimed to discuss the effects of different storage temperatures on postharvest physiological quality and antioxidant enzyme activities of Actinidia arguta. Actinidia arguta was stored at 0, 5 and 10 ℃, respectively, and relevant indicators during storage were determined. The results showed that compared against fruits stored at 5 and 10 ℃, Actinidia arguta stored at 0 ℃ significantly inhibited the browning rate and respiration intensity, and the fruits maintained higher firmness and contents of vitamin C, glutathione, and flavonoids. In addition, stored at 0 ℃ inhibited increases in relative conductivity, malondialdehyde content, peroxidase and polyphenol oxidase activities. Besides, 0 ℃ greatly maintained relatively high activities of superoxide dismutase, catalase, and glutathione reductase. In conclusion, stored at 0 ℃ can maintain a good quality of post-harvest Actinidia arguta.

Key words： storage temperature; Actinidia arguta; antioxidant enzyme activities; antioxidant capacity
