摘要
托拉斯假单胞杆菌(Pseudomonas tolaasii)是引起食用菌细菌性褐斑病的病原菌,该研究利用平皿对峙和子实体接种的方法,研究了4个不同托拉斯假单胞杆菌菌株对平菇CCEF-99菌丝体和子实体生长的影响,评价不同菌株的致病能力,为平菇品种抗病性鉴定提供备选鉴别菌株。结果表明:菌株JZB2120025的致病力最弱,病斑面积小,颜色呈淡黄色;菌株JCM21583的致病力最强,产生的病斑凹陷,颜色呈棕褐色,可作为平菇抗病性状检测的备选菌株。
Brown blotch disease,a serious mushroom disease,is usually caused by the bacterial pathogens of Pseudomonas tolaasii.In this study,the influence of four different P.tolaasii strains on the mycelium and fruit body growth of Pleurotus ostreatus CCEF-99 were tested to screen strains with strong pathogenicity and to provide backup strains for identifying resistance of mushroom varieties.The results showed that,the strain JCM21583 had the strongest pathogenic effect and could be used as identification strain to test the resistance ability of P.ostreatus against brown blotch disease.
