板栗贮藏中的病原菌及其控制

从贮藏板栗中分离并鉴定出5种主要病原菌，它们是Dothiorella gregria,Colletotrichum gloeosporioides,Papulariasp,Penicilliumsp和yeast.通过对这些病原菌的侵染条件和贮藏生态环境的研究发现除青霉外，低温自发气调能有效地抑制其它4种病原菌的蔓延，而无毒无污染的山梨酸钾又可使青霉的危害大为降低，从而确立了低温气调控制生长期感染病原菌的蔓延，以及适当的药剂防止采后感染病原菌扩散的防霉策略.

Pathogenetic Fungi Stored Chestnuts Putrid in China and Controlling Methods

Five kinds of pathogenetic fungi seperated from Chinese chestnutsin storage are identified. They are Dothiorelle gregria, Colletotrichum gloeosporioides, Papularia sp, Penicillium sp and yeast. After having studied some infecting conditions and the ecological environment in storing, knew that four of them can be effectively inhibited when chestnucts are stored in modified atmosphere at low temperature, except for penicillium sp. Some nonpoison and nonpollution agents, for example patassium sorbate, can decline the loss caused by penicillum sp. Base on the study, a scheme for storing chustnuts is set up, in which the pathogenetic fungi infecting chestnus in their growth period are inhibited stored in modified atmosphere at low temperature, and the pathogenetic fungi infecting chestnuts after harvest are inhibited by appling antifungus agent.
