作者对哈蜜瓜(Cucumis melo L.var.Saccharinus Naud.)经β辐射处理后的某些生理生化指标以及主要物质成分的变化进行了测定,并对防腐保鲜效果进行了比较。 哈蜜瓜在β辐射后的一段时间内,呼吸强度、瓜汁pH和乙醇都有增加趋势,过氧化氢酶被激活,乙烯和维生素C稍有减少,这种效应随照射剂量增大而显著。经β辐射后,瓜的腐烂率明显下降。这种结果说明,β辐射除有杀菌防腐作用外,还可用来调控哈蜜瓜的某些生理生化过程,对瓜果贮藏研究有一定的参考价值。 The authors studied some physiological and biochemical indexes of Cucumis melo L.var.Saccharinus Naud., And the change of the main components after beta radiation treatment. The preservative effect was also compared. Honeydew melon in beta radiation after a period of time, respiratory intensity, melon juice pH and ethanol have an increasing trend, catalase is activated, ethylene and vitamin C slightly reduced, this effect with the radiation dose increased significant . After β radiation, the decay rate of melons decreased significantly. This result shows that, in addition to sterilization β-radiation effect, but also can be used to regulate some of the physiological and biochemical processes honey melon, fruit and vegetable storage has some reference value.
