摘要
从闽粤桂主产区的巴戟天茎基腐病株中,分离并选用有代表性的9个茎基腐病单孢菌株。盆栽致病性测定表明,这9个菌株都有不同程度的致病力;通过PSA培养基、麦粒培养基、米饭培养基等培养试验,观察到9个菌株的菌落生长速度,状态、颜色,大小型分生孢子和厚垣孢子的形态、大小和形成方式等基本相似。经鉴定,本病原菌属于镰孢属(Fusarium Link ex Fr.)美丽组(Section Elegans Wr.)的尖镰孢(F.oxysporum Schlecht)。
The 'Fusarium wilt disease of medicinal indianmulberry occurred seriously in Fujian,Guangdong and Guangxi provinces (autonomous). All virulent isolates from diseased plants collected from these provinces were identified as Fusarium oxysporum Schlecht.
