摘要
目的:明确白木香枝枯病的病原菌,确定其是否能够诱导白木香产生沉香。方法:通过形态特征观察、rDNA-ITS序列测定分析、柯赫氏法则验证确定病原菌及其分类地位。结果:分析结果表明,侵染白木香Aquilaria sinensis的病原菌为可可毛色二孢Lasiodiplodia theobromae,该菌可诱导沉香产生。结论:首次明确白木香枝枯病的病原菌为可可毛色二孢,为利用真菌诱导白木香结香研究提供理论基础。
The research focused on identification the pathogen of Aquilaria sinensis dieback disease and confirmation the function of inducing agarwood formation by fungi. Method: The morphological observation, rDNA ITS sequence analyses, Koch's postulates and pathogenicity test were used to identify the isolates. Result: The isolates of the causal agent was Lasiodiplodia theobromae, which induced the plant to produce highly valuable agarwood. Conclusion: The first report of dieback disease of Aquilaria sinensis caused by L. theobromae, and our research results laid a theoretical foundation for agarwood production by using fungus.
