摘要: 以陕西省阎良区厚皮甜瓜为试材,采用1-甲基环丙烯(1-MCP)、焦亚硫酸钠(Na2S2O5)以及二者结合的处理方法,研究厚皮甜瓜采后生理变化及贮藏品质。结果表明:1-MCP结合Na2S2O5处理能明显延缓厚皮甜瓜硬度下降,抑制可溶性固形物含量快速上升,有效少果实腐烂,同时抑制苯丙氨酸解氨酶和过氧化物酶的活性,使过氧化氢酶和超氧化物岐化酶活性处于较高水平。在这种处理方式下,贮藏80d后,果实腐烂指数0.37、商品果率80%。1-MCP结合Na2S2O5复合处理对厚皮甜瓜具有很好的保鲜效果。

Abstract: The postharvest physiology and storage characteristics of Cucumis melo L. treated by 1-methylcyclopropene (1-MCP), sodium metabisulfite (Na2S2O5) and their combination were studied. The results demonstrated that 1-MCP combined with Na2S2O5 could delay the maturation of fruits, inhibit the increase of soluble solids, significantly reduce decay rate and also inhibit the increase of phenylanlanine ammonialyase (PAL) and peroxidase (POD) activities, thus maintaining catalase (CAT) and superoxide dismutase (SOD) activities at a high level. After 80 days of storage the decay rate and the commodity rate were 0.37 and 80%, respectively. Therefore, 1-MCP combined with Na2S2O5 can maintain high storage quality of Cucumis melo L.

Key words: Methy clopropene (1-MCP), Na2S2O5, Cucumis melo L.
