摘　　要：以新红星苹果为试材 ,研究了室温贮藏和低温贮藏两种条件下 1 MCP (1-甲基环丙烯 )对果实乙烯释放量、内源乙烯浓度、硬度、可滴定酸含量及可溶性固形物含量的影响。结果表明 ,30 0nL·L-1浓度的 1 MCP能显著抑制果实乙烯释放 ,延缓乙烯高峰的出现 ,延缓果实硬度和可滴定酸含量的下降 。The effects of 1 MCP(1 methyclopropene)treatment after fruit harvesting on ethylene production,internal ethylene concentration,flesh firmness,titratable acid and total soluble solids of'Delicious'apples were studied during the storage at the room temperature and at 0℃.The result showed that the 300nL·L -1 1 MCP treatment significantly inhibited ethylene production,delayed the ethylene peak and slowed down the decrease in the flesh firmness and titratable acid,but total soluble solids of apples was not affected by 1 MCP treatment.There is a potential application of 1 MCP in the apple storage.
