摘　　要：以磨盘柿为试材,以直接冰温贮藏为对照,研究了冰温贮藏前低温驯化对磨盘柿硬度和软化相关物质代谢的影响。结果表明:与对照相比,低温驯化可有效降低乙烯释放速率的上升,抑制多聚半乳糖醛酸酶(PG)活性、纤维素酶(CX)活性、淀粉酶活性的上升和可溶性果胶含量的升高,保持果实硬度。该研究表明,磨盘柿经低温驯化结合冰温贮藏的效果优于直接冰温贮藏的效果。Taking Mopan persinunon as material, with ice-temperature storage as control group, the effect of cold acclimation combined with ice-temperature storage （CACITS） on several physiological indexes related to fruit softening of it was studied. The results showed that cold acclimation combined with ice-temperature storage not only effectively reduced ethylene production rate,but also significantly retarded the activities of polygalacturonase （PG）,cellulose （CX） and amylase （AI）,which reduced the increasing of soluble pectin content. Therefore,cold acclimation combined with ice- temperature storage was better than ice-temperature storage alone.
