    广东香蕉枯萎病菌生理小种的鉴定

    Race Identification of Fusarium oxysporum f. sp.cubense,the Causal Agent of Banana Fusarium Wilt in Guangdong Province

    • 摘要: 以4~5片叶的组培香蕉苗和粉蕉苗为材料,采用伤根浸菌液的接种法对分离自番禺、中山、肇庆、珠海、顺德等地的香蕉枯萎病菌株进行了致病性测定,同时观察了各菌株在Komada改良培养基上菌落形态特征.结果表明在广东的确存在香蕉枯萎病菌1号和4号2个小种,认为致病性测定结合Komada改良培养基上菌落形态特征是鉴定香蕉枯萎病菌生理小种的简单、快速而又可靠的方法.

       

      Abstract: Banana Fusarium wilt,a kind of soilborne vascular disease infected by Fusarium oxysporum f.sp.cubense(E.F.Sm.) Snyd.& Hans.is threatening the banana and Fenjiao production in Guangdong Province,China.Based on the pathogenicity test on 4-5-leaf tissue-cultured banana plantlets and colony morphology on modified Komada medium,the isolates from the regions of Panyu,Zhongshan,Zhaoqing,Zhuhai and Shunde were identified as F.oxysporum f.sp.cubense race 1 and race 4 respectively.It was proved that the pathogenicity test combined with colony morphology on modified Komada medium was a simple,fast and reliable method for identifying races of Fusarium oxysporum f.sp.cubense.
