[目的]研究不同处理对甜柿在低温贮藏下生理和品质变化的影响.[方法]以不作任何处理为对照,研究保鲜袋、乙烯吸收剂、赤霉素和魔芋葡甘聚糖涂膜结合使用对果实呼吸强度、果实软化速度、细胞膜透性和营养物质变化的影响.[结果]在(1.0±0.5)℃的温度条件下,使用聚乙烯塑料薄膜袋包装和魔芋葡甘聚糖涂膜保鲜甜柿,硬果期为60 d;赤霉素、乙烯吸收剂结合保鲜膜的简易气调贮藏方法保鲜甜柿,硬果期可达90 d.赤霉素与乙烯吸收剂可单独使用,也可配合使用.[结论]该研究为甜柿贮藏方法及采后商品化处理操作规程的建立提供了相应的理论依据.%[ Objective ] The effect of different treatments on the change of physiology and quality of sweet persimmon ( Diospyros kaki Linn.F. ) under cold storage was experimented. [ Method ] The effect of the treatment such as storage bags, ethylene absorbent, GA and konjac glucomannan-coating or their combination application on the respiratory intensity, firmness, membrane permeability and the change of nutrient matter of fruit was researched and the non-treatment was taken as the CK. [ Result ] Under the condition of temperature of ( 1.0 ± 0.5 ) ℃,the firmness of fresh fruit could maintain for a period of 60 days in the treatment of the polyethylene plastic film bag or the konjac glucomannancoating. The firmness of fresh fruit could maintain for a period of 90 days in the simple method of atmosphere storage： GA or ethylene absorbent combined with fresh film preservation. Gibberellin and ethylene absorbent may be both individually used and combined. [ Conclusion] The corresponding theoretical basis of the establishment of the storage method and the operation procedure of the sweet persimmon fruit were provided for its commercialization.
