摘　　要：[目的]明确引起棕竹叶片炭疽病的病原菌种类。[方法]通过常规组织分类法、形态学方法以及多基因系统发育方法对棕竹炭疽病进行分离鉴定。[结果]从棕竹病叶上分离的病原菌可以侵染有伤的棕竹叶片并引发炭疽病;多基因系统发育树分析表明,该病原菌与暹罗刺盘孢菌株聚为一类。[结论]引起棕竹炭疽病的病原菌为胶孢炭疽菌(Colletotrichum gloeosporioides)类群中的暹罗刺盘孢菌(C.siamense)。[Purpose]To identify the pathogen causing anthracnose on Rhapis excelsa.[Method]Three methods were used,including the conventional tissue classification,morphological phenotyping and multi-gene phylogenetic tree analysis.[Result]The isolated pathogen could infect the damaged leaves of R.excelsa and cause anthracnose.Polygenic phylogenetic tree analysis found that the pathogen and Colletorichum siamense were grouped into one branch.[Conclusion]The pathogen causing anthracnose on R.excelsa was C.siamense.
