The mature fruits of pear cultivar ‘Shannongcui ’ were used to investigate the changes of firm-ness,related physiological indexes and their correlations during storage under four treatments including room temperature, low temperature, low temperature with 1-methylcyclopropene and low temperature with plastic wrap.The results showed that the ‘Shannongcui ’ pear was not resistant to storage , and was sensitive to ethyl-ene.Low temperature combined with 1-MCP or plastic wrap treatment could delay and decrease the peak of ethylene production and activities of PG ,β-Gal and Cx , so the storage life could be extended to more than 200 days and the good fresh food quality could be maintained .%以‘山农脆’梨为试材，研究常温、低温、低温＋1-MCP及低温＋保鲜膜4个处理的‘山农脆’梨采后贮藏期间硬度及相关生理指标的变化及其相关性。结果表明，‘山农脆’梨属乙烯敏感型的不耐贮品种，低温结合1-MCP或保鲜膜处理能够有效推迟乙烯释放及PG、β-Gal和Cx等相关酶活性高峰的到来并降低其峰值，贮藏期可达200 d以上，并保持较好的鲜食品质。
