摘要
将感染褐斑病的糙皮侧耳(Pleurotus ostreatus)子实体进行组织分离,获得细菌菌株PH-1,经过致病性测定、16S rDNA序列分析及生理生化特性测定,确定鞘氨醇杆菌(Sphingobacterium sp.)为糙皮侧耳褐斑病的病原菌;采用平板抑菌法研究大蒜(Allium sativum)、蒲公英(Taraxacum mongolicum)和鱼腥草(Houttuynia cordata)粗提液对鞘氨醇杆菌的防治效果,结果表明大蒜粗提液可以有效抑制该病原菌的生长。
By tissue separation of Pleurotus ostreatus fruiting body suffering from brown rot disease,a pathogenic strain PH-1 was obtained.After pathogenicity test,16 S rDNA sequence analysis and determination of physiological and biochemical characteristics,PH-1 was determined to be Sphingobacterium sp.Crude extracts of Allium sativum,Taraxacum mongolicum,Houttuynia cordata were tested on PH-1 for growth inhibition effect,and the crude extract of A.sativum effectively inhibited the growth of PH-1.
