| 摘 要： | 番荔枝果实采后在自然室温(26～33 ℃) 条件下贮藏寿命仅为3 d。随着贮藏温度下降, 果实呼吸和乙烯释放高峰推迟, 果肉质膜透性和果胶甲酯酶活性明显下降, 贮藏寿命延至15 d 左右。10 ℃是番荔枝果实后熟的临界温度, 低于10 ℃则后熟不充分, 甚至发生冷害。采后番荔枝果实后熟过程中, 果肉PPO、POD、SOD 和CAT活性极低, 并且在果实尚未软化时急剧下降。

| Abstract: | Sweetsop fruits after harvest were sensitive to storage temperature. At room temperature (26 -33 ℃) , the shelf-life of the fruit was only 3 days. With a decrease of storage temperature , the climacteric peaks of respiration and ethylene release of the fruits were delayed , and the cell membrane permeability and the activities of pectin nethylesterase in the pulp decreased. As a result , the shelf-life was extended to 15 days with a optimal storagetemperature of 10 ℃. Below 10 ℃, the fruit did not ripen completely and showed chilling injury. Activities of PPO, POD , SOD and CAT of harvested sweetsop were low , and all decreased rapidly before appearance of fruit softening. |
