呼吸跃变型水果芒果对乙烯非常敏感。1—MCP是一种有效的乙烯作用抑制剂,它能抑制乙烯所诱导的与果实后熟相关的一系列生理生化反应,进而延缓采后呼吸跃变型果实的衰老进程.保持果实的贮藏品质,综述了1-MCP的作用机理及1-MCP对采后芒果的呼吸速率、乙烯产量、果实品质及生理病害等生理生化指标的研究现状,同时介绍了1—MCP结构类似物以及1—MCP结合其他保鲜方法的应用情况,并对1-MCP应用前景进行了展望.以期为1—MCP在芒果贮藏保鲜中的应用和研究提供参考。
Mango is a typical climacteric fruit that is very sensitive to ethylene. 1-MCP (1- methylcyclopene) is a new ethylene action inhibitor,which can occupy ethylene receptor irreversibly ,and then blocks the normal combination of ethylene to combine on the receptor, inhibits a series of physiological and biochemical reactions associated with fi-uit ripening,thus delays fruit senescence and maintains fruit quality during postharvest storage. This review ibcuses on the mechanism and eftect of 1-MCP on postharvest ripening of mango fi'uit,including biochemical and physiological indices such as respiration rate,ethylene production output,fruit quality and physiological disorders etc. At the same time,application of 1-MCP structural analogues and 1-MCP in combination with other preservation methods are also introduced. The foreground in application of 1-MCP is prospected to provide references for the application and research of 1-MCP on mango postharvest handling and storage.
