Abstract： The studytook waterchestnuts from Lipu，Guangxi as the research object，with weight loss，hardness， relative conductivity，MDA，SSC，total phenols，flavonoidsand quinone contentsserving as evaluation indicators.The effects of different irradiation doses of 60Co-γ -rays（0，2，4，6，8 kGy）on the preservation efficacy of fresh water chestnuts were investigated.The results showed that during the storage period of 40 d， the 2 kGy 60Co-γ -ray irradiation treatment group had a weight loss rate of 0.18% ，hardness of 3 810 g， relative conductivity of 17.2% ，and MDA content of 0.0020-0.002 6μmol/gFW. It could reduce SSC losses， lower the content of total phenolic，flavonoid，andquinone，inhibit bacterial growth，and effectively delay thedecline in water chestnut quality. Therefore，the 2 kGy 60Co-γ -ray irradiation treatment was identified as the optimal dose for postharvest preservation offresh water chestnuts inthe Guangxi，which might provide a theoretical basis for irradiation preservation of postharvest water chestnuts.
