【摘要】 通过测定猕猴桃贮藏过程中生理生化指标的变化,研究1-甲基环丙烯微胶囊剂采摘后处理对猕猴桃的保鲜效果。4个月低温贮藏期内猕猴桃果肉硬度、失重率及可溶性固形物含量的变化表明:1-MCP微胶囊剂250,500,750nl/L三个剂量处理的猕猴桃的果肉硬度、可溶性固形物含量均高于空白对照处理,而失重率远小于空白对照处理;保鲜效果随着剂量的增加而增加,以750nl/L剂量处理的保鲜效果最佳。作为优良的乙烯受体抑制剂,1-MCP可以抢先与细胞内部相关受体结合,封阻乙烯与相关受体的结合路径,从而延迟与成熟有关的生理生化反应的发生,保持果实良好的外观品质和营养价值,最大限度的延长果实货架期。更多还原

【Abstract】 This article researched the effects of 1-MCP(1-methyclopropence) treatment after harvesting on flesh firmness,weightlessnesss and total soluble solids of actindia. The result indicated that 1-MCP could delay the decrease in flesh firmnesss,weightlessnesss and total soluble solids of actindia.The fresh-keeping effect increases with the dose and the 750 nL/L 1-MCP treatments is the best. 1-MCP could combine with the related receptor in the cell ahead of ethylene and delay the maturity-related physiological and biochemical reactions. So 1-MCP may maintain the appearance quality and nutritional value and extend the fruit shelf-life in maximum.更多还原
