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.
