| 摘 要： | 以“哈斯”油梨果实为试材,在20℃和相对湿度85%~90%的条件下,研究了20、40、60、80nL/L的1-甲基环丙烯(1-MCP)对果实的乙烯释放量、硬度、褐变指数、多聚半乳糖醛酸酶(PG)、多酚氧化酶(PPO)和纤维素酶活性的影响。结果表明,与对照相比,1-MCP可以明显降低果实的乙烯释放量,使果实乙烯峰值约推迟8~10d出现;在处理后的10d内,1-MCP能有效保持果实的颜色;1-MCP能有效抑制PPO、纤维素酶的活性,并推迟多聚半乳糖醛酸酶活性高峰出现的时间。

| Abstract: | 1-Methylcyclopropene(1-MCP),an inhobitor of ethylene action, was applied to avocado(Persea americana Mill.cv 'Hass')fruit which were treated with various doses of 1-MCP for 24 h, then stored at 20℃ and RH 85%～90% for ripening assessment.Ethylene production,firmness, brown index,polygalacturonase,cellulase and polyphenol oxidase activity were determined during storage.It was found that 1-MCP could reduce ethylene production,decrease the loss of fruit firmness,monito the cellulase, PPO and PG activity.1-MCP was a potential rigening delayer of avocado. |
