摘要
番荔枝果实采后在自然室温 ( 2 6~ 33℃ )条件下贮藏寿命仅为 3d。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 15d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 。
Sweetsop fruits after harvest were sensitive to stora ge 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 respirat ion and ethylene release of the fruits were delayed,and the cell membrane perme ability and the activities of pectin nethylesterase in the pulp decreased.As a r esult,the shelf-life was extended to 15 days with a optimal storage temperature of 10℃.Below 10℃,the fruit did not ripen completely and showed chilling injur y.Activities of PPO,POD,SOD and CAT of harvested sweetsop were low,and all decre ased rapidly before appearance of fruit softening.
