贵州油茶间座壳叶枯病病原种类鉴定与生物学特性研究
Identification and biological characteristics of the Diaporthe species of leaf blight of Camellia oleifera mesocosm in Guizhou
[目的]研究引起贵州油茶叶枯病病原菌种类及其主要生物学特性,筛选最佳防治药剂,为探明其发生传播规律和防治叶枯病奠定基础。[方法]采用组织分离法获得病原菌菌株GZU-Y2,通过形态学分析、分子生物学鉴定以及柯赫氏法则对菌株进行鉴定,并采用十字交叉法来对不同环境条件下的病原菌菌丝生长直径进行测量,以观察病原菌生物学特性,用生长速率法测定了 5 种市售杀菌剂对该病原菌菌丝生长的抑制作用。[结果]结果表明,油茶叶枯病致病菌分离株 GZU-Y2 的培养物菌…查看全部>>
[Objective]To study the species of pathogens causing Camellia oleifera leaf blight in Guizhou and their main biological characteristics,to screen the best control agents and to clarify the effect of different conditions on Camellia oleifera leaf blight.[Method]The pathogenic strain GZU-Y2 was obtained by tissue isolation,and identified by morphological analysis,molecular biology and Koch's method.The inhibition of the mycelial growth of the pathogen by five …查看全部>>
