Abstract

Abstract: The fruit of Kiwifmit (Actinnida deliciosa ‘Bruno’) was used to investigate the regulation of 1·MCP on fruit ripening and softening at 20 ℃． The results showed that there were two distinct stages of fruit softening， i.e. the initiating stage of softening or the stage of slowly softening, and the stage of fast softening in ripening fruit and that the process of system Ⅰ transforming to system Ⅱ ethylene biosynthesis and the ethylene climacteric peak were postponed in the fruit treated with 1·MCP，which result a slowed softening rate being slowed and influence the activities of LOX and AOS, and the up·stream regulators of ethylene biosyn thesis，

Key words: 1·MCP, Kiwifruit, Storage, Ripening and softening, Regulation
