摘 要:从松材线虫病致死的松材木质部和松材线虫体表分离到3个出现频率较高的细菌菌株,菌株Njh、Njt和Njw.经鉴定3种细菌分别为荧光假单胞菌Ⅰ型(Pseudomonas fluorescens biotype Ⅰ)荧光假单胞菌Ⅱ型(Pseudomonas fluorescens biotype Ⅱ)和泛菌属某种(Pantoea sp.).用牛肉膏蛋白胨液体培养基振荡培养细菌,培养液直接处理黑松愈伤组织,测定各细菌的产毒能力.与对照(空白培养液)相比,3种细菌的培养原液都可对黑松愈伤组织产生明显影响,其中菌株Njh和菌株Njt可以在2?d内使愈伤组织明显变色,菌株Njw处理变色较慢.表明菌株Njh和Njt培养液内有大量致萎毒性物质存在.
