摘　　要：【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。[Objective] ＇Suli＇ pear is the most important pear cultivar with the largest cultivated areas and highest production in China. In Henan province, it is mainly distributed in Ningling county, which has a history of about 200 years of cultivation. ＇Suli＇ pear has many good characters such as high yield, good taste, and good postharvest performance, and serves as the pillar industry in local areas. 50%-60% pear production is stored in the semi-underground ventilated storeroom. Local farmers usually pack the fruit in wood boxes. The semi-underground ventilated storeroom is convenient and economical. During storage, pear fruit become wrinkled, and the fruit taste and quality decline quickly. 1-MCP improves postharvest performance in many fruits. Packing fruit with various bags reduces 02 concentration and increases CO2 concentration in the bags, reducing fruit respiration. In this paper, 1-MCP combined with fruit packing with different types of bags were evaluated for elongating storage life of ＇ Suli＇ pear.
