摘　　要： 以库尔勒香梨为试验材料,于0℃和5℃2种条件下贮藏60 d后,取出放在室温20℃左右的条件下,模拟货架期,分别对果实的失重率、硬度、可溶性固形物含量、可滴定酸含量、固酸比、Vc、叶绿素含量、呼吸速率、乙烯释放量、PPO活性、电解质渗透率进行测定,探讨不同贮藏温度对货架期香梨品质和生理活性的影响。结果表明:0℃香梨,在货架期间品质变化较5℃小,而5℃的香梨在货架前期生理活性均比0℃高,后期低于0℃。 This paper set the Pyres bretschneideri Rehd as test materials, they were stored separately at temperature 0℃ and 5 ℃ for 60 d, then they were taken out and stored at about room temperature 20℃ to simulate shelf-life. The weight loss, firmness,soluhle solids, titratable acid, solid-acid ratio, Ve, chlorophyll content, the respiration rate, the releasing volume of ethylene,the relative conductivity and the activity of oxidase polyphenol were determined to explore the effect of different storage temperature on the shelf-life quality and physiology of pear. The results showed that the quality of pear were stored at 0℃ were better,the physiology activity stored at 5℃ were higher during the early shelf-life and lower the later shelf-life.

关 键 词： 贮藏温度 货架期 香梨 品质 生理活性
