菌丝融合型测定结果表明，G!个茭白纹枯病菌菌株隶属于两个菌丝融合群：G“个属>?$群，占测定菌株的CG3CBS，其中>?$ET>、>?$ETJ两亚群菌株依次为!D与N，有两菌株为>?D，占N3!BS。显然，>?$ET>为优势融合群，占测定菌株的FBS。融合群致病性测定结果表明，>?$ET>致病性强，>?$ETJ弱，>?D基本不致病。茭白与水稻两种纹枯病菌交互接种，其发病基本一致。由此，作者认为这两种纹枯病菌为同一病原物，或者说茭白、水稻是同一病原物的两个寄主植物。 The results of mycelial fusion showed that the strains of K. albicans belonged to two mycelial fusion groups: G ”genus"> $ group, accounting for CG3CBS of the tested strains, among which>? $ ET>,> $ ETJ two subgroups of strains followed by! D and N, two strains of>? D, accounting for N3! BS. Obviously,>? ET> predominant fusion group, accounting for the measured strains of FBS. Fusion group pathogenicity The results showed that the pathogenicity of>? $ ET> strong,>? $ ETJ weak,>? D does not cause disease .White and rice two Rhizoctonia soaked bacteria, the incidence is basically the same .Thus, the author thinks Both of the two Rhizoctonia solani are the same pathogens, or white rice, the two host plants of the same pathogen.
