摘 要：
采用西洋梨品种中的"凯斯凯德"果实为试材,对9月5日(T1)、9月15日(T2)9、月25日(T3)采收的果实各生理指标变化情况进行测定。结果表明:20℃下贮藏的果实T1、T2、T3,分别在采收后12、106、d左右完成后熟,T2果实后熟品质较好,T1果实较耐贮藏,T3果实货架寿命较短。各采收期果实在0℃贮藏60 d内不会完成后熟软化过程,转入20℃后T1果实基本失去了正常后熟能力,T2、T3果实与直接贮藏于20℃条件下果实相比,后熟时间均提前了2 d,分别在贮藏的第8、4天完成后熟过程。

摘 要：
Taking "Cascade" Pear fruit as materials,different harvested time on 5th September(T1),15th September(T2),25th September(T3)of the fruits change in physiological indicators were measured.The results showed that storage of fruit T1,T2,T3 under 20℃,the harvest time was about to complete after-ripening at 12,10,6 d,T2 fruit had better ripening quality,T1 fruit had storage-resistant than others,T3 fruit's shelf life was short.different harvest time of fruit stored 60 d at 0℃ would not complete the process of ripening and softening,T1 fruit lost it's normal ripening basic ability at 20℃,T2,T3 fruit directly stored at 20℃,compared to the fruit,ripening time were ahead of 2 days,respectively,they finished their ripening on the 4th and 8th day after storage,respectively.
