摘要: 以红富士苹果为实验材料,研究了1-MCP(1-甲基环丙烯)处理对常温贮藏下苹果生理代谢及贮藏品质的影响。结果表明,采用1μl/L和2μl/L的1-MCP处理,可以抑制苹果呼吸强度和乙烯释放量,保持较高的VC及可溶性固形物含量。同时1-MCP处理对苹果PE和PG活性有一定的抑制作用,阻止了原果胶的降解,使果肉保持较高的原果胶含量和较低的可溶性果胶含量,从而延缓果实硬度的下降。

Abstract: The effects of exogenously applied 1-MCP on physiological and quality changes in harvested apple cv.Fuji fruitswere investigated.Treatment with 1or 2μl/L 1-MCP significantly inhibited the senescence process of harvested apples,asmanifested in low levels of ethylene production and respiratory rate butin high levels of VC retaining and total soluble solidcontents.In fruits treated with 1-MCP,low levels of PE and PG activity were detected,the degradation of protopectin was inhibited,and fruit firmness was maintained at higher level in comparison with control fruits.The experimental results suggested that 1-MCPmight delay fruit senescence by inhibiting ethylene production,thereby keeping better quality during ambient temperaturestorage.
