摘要
研究不同采收成熟度（六成熟和八成熟）、不同品种（‘红贵妃’、‘台农1号’和‘金煌’）的芒果果实对1一MCP处理的反应。结果表明：1）在同一采收成熟度下，3个芒果品种对1．MCP处理的反应不同，在贮藏同一时间，‘台农’果实的贮藏品质及生理变化最快，表现为较高的病情指数、色度口。、TSS、SOD、POD和LOX活性，以及较低的果实硬度，其次是‘金煌’品种，‘红贵妃’果实成熟衰老的速度最慢；2）对于同一品种不同采收成熟度，低成熟度的果实比高成熟度的果实具有较低的病情指数、色度a和较高的果实硬度、SOD、POD和LOX活性，而细胞膜透性差异不显著；3）1—MCP处理后，完熟时六成熟‘台农’果实的含糖量略低于八成熟果实，但TSS含量差异不大，而‘红贵妃’和‘金煌’芒果，八成熟果实的TSS含量明显高于六成熟果实。说明3个芒果品种中，‘台农’果实对1一MCP处理的保鲜反应最差，‘红贵妃’和‘金煌’果实对1一MCP处理的保鲜反应较好。
Abstraet. The response of mango fruits from different maturity stages （60% and 80%） and cultivars （＇Hongguifei＇, ＇Tainong 1＇ and ＇Jinhuang＇） to 1-MCP treatment was investigated. The results showed that： （1） for mango fruits with the same maturity the response of three mango cultivars to 1-MCP was different. ＇Tainongl＇ mango fruits revealed the fastest change in storage quality and physiology with higher disease index, color a＊, TSS content, SOD, POD and LOX activities, and lower fruit fmamess, followed by ＇Jinhuang＇ and ＇Hongguifei＇ fruits. （2） for mango fruits from different maturity stages and the same cultivar, mango fnfits with lower maturity degree revealed lower disease index and color a＊, and higher fruit fLrmness and SOD, POD and LOX activities than mango fruits with higher maturity degree. However, the cell membrane permeability of mango fruits with both maturity degrees did not exhibit an obvious difference. （3） When mango fruits were ripened completely, no significant difference in TSS content was observed for ＇Tainong 1＇ mango fruits harvested at degrees of maturity, although mango fruits with 60% maturity contained slightly smaller amounts of sugar than mango fruits with 80% maturity; as for ＇Hongguifei＇ and ＇Jinhuang＇ cultivars, mango fruits with 80% maturity revealed significantly higher TSS contents than mango fruits with 60% maturity. Therefore, 1-MCP treatment was effective in preserving ＇Hongguifei＇ and ＇Jinhuang＇ mango fruits rather than ＇Tainong 1＇ mango fruits.
