食用菌提取物对烟草花叶病毒的抑制作用

Inhibition of Incidence of TMV by Extracts from the Fungus

从钝化(提取物与病毒混合后接种)、预防(施用提取物24 h后接种病毒)、治疗(接种病毒24 h后施用提取物)3个不同时期,在心叶烟上测试了8种食用菌乙醇提取物水溶液对烟草花叶病毒(Tobacco mosaic virus,TMV)的抑制作用。试验结果表明:8种食用菌提取物在体外都具有钝化病毒(TMV)及抑制病毒(TMV)侵染的作用;除鸡油菌(Cantharellus minorPeck)外,其它7种食用菌提取物对TMV有不同程度的治疗作用。

The antiviral properties of ethanol extracts from eight kinds of fungi were studied against To- bacco mosaic virus. The extracts were applied to Nicotiana glutinosa at three different stages, i. e. at the time of inoculation（ mixed with virus inoculation）, pre-inoculation（24 h before virus inoculation）, post-inoculation （24 h after virus inoculation）. The results as follows： all eight extracts deactivated TMV in vitro and have inhibition of the infectory of TMV, and seven extracts showed therapeutically activity in different degree on TMV except Cantharellus minor Peck.
