OBJECTIVE
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.
目的
本研究聚焦于鉴定白木香枝枯病的病原菌，并确证真菌诱导沉香形成的功能。
方法
采用形态学观察、rDNA ITS序列分析、柯赫氏法则和致病性测试来鉴定分离物。
结果
致病病原体的分离物为可可毛色二孢，它可诱导植株产生极具价值的沉香。
结论
首次报道了由可可毛色二孢引起的白木香枝枯病，我们的研究结果为利用真菌生产沉香奠定了理论基础。
