| 摘 要： | 在广州、南京和扬州等地红掌病株上分离的炭疽菌中存在形态差异明显的两个群体。各选取两个代表菌株进行形态特征、致病性、寄主范围鉴定及核糖体DNA ITS序列分析。结果表明，红掌炭疽病病株上有两种致病菌：胶孢炭疽和毁灭炭疽，后者导致红掌炭疽病为首次报道。

| Abstract: | Among the Colletotrichum strains isolated from Anthurium andraeanum in Guangzhou, Nanjing, Yangzhou, there were two groups exhibited different morphology on the culture. Two strains of each group were chose for species identification with the morphological character, pathogencity on plants, host range and the sequence of ribosomal DNA-ITS. The results indicated that these strains belong to two species, Colletotrichum gloeosporioides and C. destructivum, and the latter was first reported as a pathogen in Anthurium andraeanum. Both species could infect solely, crossly and latently. |
