摘要
将佛手瓜分别在-1-1℃、3-5℃、8-10℃和常温下贮藏,测定其贮藏过程中呼吸强度、腐烂指数、保护酶活性及相关产物的变化。结果表明,适当低温处理可以降低佛手瓜呼吸强度的快速升高,延长其贮藏期,温度过低则产生冷害,腐烂率增大;SOD和CAT活性与细胞膜透性、MDA和O2.-含量表现出一定的相关性,而POD活性与佛手瓜成熟衰老相关性不明显。
The chayote fruits were stored under - 1- 1 ℃, 3 - 5 ℃, 8 -10 ℃ and ordinary temperature. The changes of respiration, rotten exponent, activity of protective enzyme and the other relevant substance of the chayote fruits were examined. The results showed that appropriate low temperature could effectively reduce the increase of respiration, and prolong the storage life of chayote fruits, but if the temperature was too low, the cold injury could be occurred; there was a certain relativity between SOD activity,CAT activity and membrane leakage, MDA content, O2^＊ - content, but the relativity of POD activity and the chayote fruits＇ decrepitude was not obvious.
