摘要
目的:针对桔梗立枯病是桔梗栽培生产上重要的植物病害,明确桔梗立枯病的病原菌。方法:通过形态特征观察、rDNA-ITS序列测定分析和柯赫氏法则验证,确定病原菌的种类。结果:病原菌形态学观察和核糖体DNA ITS序列分析结果表明,桔梗立枯病的病原菌为立枯丝核菌Rhizoctonia solani。结论:明确桔梗立枯病的病原菌为立枯丝核菌。
Objective： To isolate and identify pathogen of the seedling blight occurred in Platycodon grandiflorum. Method： The morphological observation, rDNA ITS sequence analysis, and Koch＇s postulates were used to identify the isolates of the causal agent. Result： The isolates of the causal agent was Rhizoctonia solani. Conclusion： The result confirmed that R. solani is the patho- gen of seedling blight of P. grandiflorum.
