摘　　要：以华红苹果为材料,研究1-MCP和小包装自发气调包装(MAP)对苹果冷藏(0℃)期间品质的影响。结果表明:1-MCP和MAP均可有效控制华红苹果果实货架期返糖现象的发生,抑制果实货架期间呼吸强度和乙烯释放量的增加,减缓果实硬度、可溶性固形物含量和可滴定酸含量的下降,抑制果皮亮度和细胞膜透性的增加。其中,0.02mm PE袋包装和0.04mm PVC袋包装均未使华红苹果产生CO2伤害,为较耐CO2品种。果皮亮度和细胞膜透性可作为华红苹果衰老与否的衡量指标,可溶性固形物和可滴定酸含量可作为华红苹果品质维持好坏的衡量指标。包装方式延长贮藏时间的顺序为:1-MCP>0.04mm PVC袋>0.02mm PE袋>对照;包装方式维持果实品质能力的顺序为:0.04mm PVC袋>1-MCP>0.02mm PE袋>对照。The effects of 1-MCP and modified atmosphere packaging（MAP）on the fresh-keeping and quality of＇Huahong＇ apples were investigated during cold storage（0℃）in this study.The results indicated that,compared with control group,1MCP or MAP treatment significantly inhibited ethylene production and respiration rate,delayed the decrease of fruit firmness, soluble solid content and titratable acid,and inhibited the increase of L value and cell membrane permeability.No CO2 injury was found in＇Huahong＇apple packaged in 0.02 mm PE and 0.04 mm PVC bags,which suggests that＇Huahong＇apple is resistant to carbon dioxide injury.The storage life of＇Huahong＇apple was prolonged by different treatments in the following order：1-MCP0.04 mm PVC bags0.02 mm PE bagscontrol.However,the quality of＇Huahong＇apple was maintained in the following order：0.04 mm PVC bags1-MCP0.02 mm PE bagscontrol.
