摘　　要：以胡萝卜为试材,采用乙烯及乙烯受体抑制剂(1-甲基环丙烯)处理,通过对贮藏60d后胡萝卜的品质劣变率(长须根率、腐烂指数、出薹率)、外观指数、可溶性糖含量及多酚氧化酶活性进行测定,研究了1-MCP对胡萝卜采后贮藏品质的影响。结果表明:1-MCP结合手洗贮藏可抑制胡萝卜贮藏期间的品质劣变率、抑制可溶性糖含量的损失、保持较高的外观指数及抑制多酚氧化酶(PPO)活性。手洗后贮藏则可有效改善胡萝卜贮藏期间的表皮褐变问题。Carrots were used as teat materials and were treated by ethylene and ethylene receptor inhibitor（1-MCP）to reveal the effect of 1-MCP on postharvest carrots by some indexes measured after 60 days,which included quality deterioration rate（rate of fibrous roots,rotting index,bolting rate）,appearance index,soluble sugar content and activity of PPO in different treatments.The results showed that the quality deterioration rate and the loss of soluble sugar content were inhibited by 1-MCP combined with hand washing during the storage.And this treatment could maintain higher appearance index and lower activity of PPO.Epidermis browning of carrots could be improved effectively by hand washing prior to storage.
