摘要(Abstract)：

【目的】了解半地下通风库的温湿度变化,明确‘金顶谢花’酥梨适合的保鲜处理方式。【方法】以不同保鲜袋包装结合1-MCP处理,在半地下通风库贮藏条件下,探讨‘金顶谢花’酥梨果实品质的变化规律。【结果】(1)保鲜袋包装有利于维持酥梨果实的原有色泽。贮藏期间果实的L*值均高于对照,a*值上升幅度也明显小于对照,结合1-MCP处理,效果更明显,其中以微孔袋+1-MCP处理效果最好。(2)保鲜袋包装显著降低了果实失重率。贮藏200 d时对照失重率高达11.1%,微孔袋包装失重率在0~1%,打孔袋包装在2%~3%,差异比较显著。(3)保鲜袋包装可有效地抑制果实硬度、可溶性固形物含量的下降,保持良好的果实风味;1-MCP处理对果实硬度、可溶性固形物含量有明显影响,同种保鲜袋包装,经过1-MCP处理的变化幅度均小于未处理的,微孔袋+1-MCP处理效果最好。(4)1-MCP结合保鲜袋处理保持了贮藏过程中梨果实抗氧化活性,保持了POD活性,降低了PPO活性以及MDA含量等,同时推迟了POD、PPO活性高峰出现的时间。(5)综合各项生理指标,在微孔袋+1-MCP处理下,宁陵酥梨最佳贮藏期限在135 d以内,最多不超过170 d。【结论】‘金顶谢花’酥梨不宜裸果贮藏。保鲜袋结合小包装1-MCP既操作方便,又有良好的保鲜效果,其中以微孔袋+1-MCP处理效果最好。在此条件下,9月底开始贮藏的酥梨最佳贮藏期限在135 d以内。
