引起棉花黄萎病的病原菌大丽轮枝菌在棉花上存在致病力强弱不同的菌株。Schnathorst 根据菌株对3个棉花品种(DPL、Acala 4—42、Tanguis 2855)致病力测定结果,证明致病力强弱显著不同。Bredikhina 依据在不同棉花品种(108—F
The pathogen causing Verticillium dahliae has existing different virulence strains in cotton. Schnathorst demonstrated significant differences in virulence depending on the pathogenicity of the strains against three cotton cultivars (DPL, Acala 4-42, Tanguis 2855). Bredikhina is based on different cotton varieties (108-F
