| 摘要: |
| 米兰炭疽病是米兰的主要病害之一,多发生在从广东引种到北方的苗株及栽植后的缓苗期,病害发展迅速,造成大量毁株。根据病原菌的形态、培养性状、致病性及寄主范围鉴定为围小丛壳菌[Glomerella cingulata(Stonem.)Spauld.et Schrenk],分生孢子阶段为盘长孢状刺盘孢(Colletotrichumgloeosporioides Penz.)。该菌在米兰上寄生迄今未见报导。 |

| Abstract: |
| Anthracnose is a serious disease of chu-lan tree in North China.It causes leaf spot and canker,and often occurs at the seedling stage or under transplanting conditions when introduced from Guangdong Pro- vince to North China.The disease spreads so rapidly that a great am- ount of these valuable plants could be destroyed. The pathogenic fungus was identified as Glomerella cingulata(sto- nem.)Spauld.et Schrenk.by means of comparative studies of the mo- rphological characters,host range and culture properties ... |
