Huang-hua' pear fruit was a typical climacteric fruit after harvest, and the fruit senescence-related factors, such as LOX activity, 02" content, AOS activity, ACC synthase activity, ACC content, ACC oxidase activity and ethylene production, changed with peaks at 20 "C. The activities of LOX, AOS, ACC synthase, ACC oxidase and the accumulation of O2 ", ACC content and ethylene synthesis were inhibited when stored at 1癈. And the severity of flesh floss and fruit decay was lightened. Low temperature combined with polyethylene film bag packing (PEF1 and PEF2) could further decrease the rate of weight loss, flesh floss, and fruit decay and keep preferable freshness. When PEF1 and PEF2 packing fruits were transferred to shelf life at 20 "C after storage at 1癈. The activities of LOX, AOS, ACC synthase, ACC oxidase could be suppressed and the accumulation of 02 , ACC content and ethylene production were slowed down to a certain extent, especially during the shelf life after 60 d storage. PEF1 and PEF2 packing fruit could maintain higher firmness as well, and the effects became more distinct along with the storage period, there existed no significant difference between PEF1 and PEF2 treatments.

试验结果表明，在20℃下，LOX活性、O2-水平、AOS活性、ACC合成酶活性、ACC含量、ACC氧化酶活性及乙烯的生成，均呈峰形变化；1℃处理可抑制LOX、AOS、ACC合成酶、ACC氧化酶的活性和O2-、ACC的积累，抑制贮藏果实的乙烯合成，减轻果肉发绵和果实腐烂。1℃下贮藏的果实，若结合不同聚乙烯薄膜袋(PEF1和PEF2)小包装，可以进一步降低果肉发绵率和果实腐烂率，保持果实新鲜度；当果实经过一段时间贮藏后，转移到20℃下，在货架期间，PEF1和PEF2对果实成熟衰老各个相关因子均有不同程度的抑制效应，主要表现在贮藏60d后的货架期间，同时维持较高的果实硬度，对硬度的影响随着贮藏时间的延长愈加明显，PEF1和PEF2处理效果之间无显著差异。
