摘　　要：以南果梨为试材,研究不同浓度(0、0.6、0.9、1.2、1.5、1.8 mg/L)的乙烯利催熟处理对冷藏(0℃)60 d后1-MCP处理(浓度1.0μL/L)及未处理的果实在35 d货架期间生理品质的影响,以确定采后经不同处理的果实冷藏后适宜的乙烯利催熟浓度。结果表明,采用0.9 mL/L浓度的乙烯利催熟未经1-MCP处理的冷藏南果梨果实硬度最低、丙二醛含量和膜相对透性最高,加速了果实的后熟进程,催熟效果最好;采用1.5 mL/L浓度的乙烯利催熟经1-MCP处理的冷藏果实硬度最低,丙二醛含量、呼吸强度和乙烯释放量最高,使果实最早进入了适宜食用期,催熟效果显著好于其他处理。In order to determine optimum ethephon ripening concentration of Nanguo pear with different treatments after storage, effects of different ethephon ripening concentrations （0, 0.6, 0.9, 1.2, 1.5, 1.8 mg/L） on physiology and quality of fruit with 1-MCP （1.0 μL/L）treatment and control during shelf life of 35 days after 60 days under cold storage （0℃） were studied. The results showed that, fruit with ethephon ripening concentration of 0.9 mL/L and control treatment, had the lowest hardness, the highest MDA content and membrane relative permeation ability, which accelerated fruit ripening progress after storage, and the ripening effect was the best. Fruit with ethephon ripening concentration of 1.5 mL/L and 1-MCP treatment, had lower hardness, higher MDA content, respiration intensity and ethylene production, which fruit was the earliest suitable for eat and the ripening effect was significantly better than all other treatments.
