【摘要】[Objective] The effects of different preservatives on post-harvest physiological and storage quality in Ginkgo biloba seeds were studied for the purpose to find a way to prolong the storage life of Ginkgo seeds. [ Method ] Ginkgo biloba seeds called\were treated with different preservatives(sodium dichloroisocyanurate, C1O2 tablets, grape preservative tablets and thiabendazole ), and the changes rule about the physiology and biochemistry and the storage quality during storage under 4°C were studied. [ Result] The respiratory intensity of Ginkgo biloba seeds was inhibited and the increase of MDA content was suppressed by thiabendazole and low membrane permeability was maintained. The activities of POD and CAT were maintained at higher levels at the end of storage by thiabendazole, and they were 1970.3 U·g-1 and 826.2 U·g-1, respectively. The generation of reducing

and

were

by

thiabendazole ,and the starch content was maintained at higher levels which was 21.39% at the end of storage.The water content of Ginkgo biloba seeds soaked in thiabendazole solution was increased. The propagation of pathogens could be inhibited by thiabendazole and
