| 中文摘要: |
| 首次报导了重寄生菌寄生黄柏鞘锈菌(Coleosporium phellodendri Kom)的重寄生现象。重寄生菌寄生在黄柏鞘锈菌的夏孢子堆上,在不同的程度上阻碍了鞘锈菌夏孢子堆的发育和夏孢子的释放,寄生严重时甚至不能形成夏孢子。调查表明,黄柏鞘锈菌重寄生菌在7月底8月初开始发生,9月中下旬达到高峰,该重寄生菌在雅安周边县(区)的黄柏鞘锈菌上自然寄生很普遍,在一些黄柏林地,自然重寄生率高达100%,重寄生指数为60～90。经鉴定,黄柏鞘锈菌的重寄生菌为柱隔孢菌(Ramulariasp.)。 |
| 英文摘要: |
| The hyperparasitism of Coleosporium phellodendri causing rust of Phellodendron amurens was firstly reported in this paper.The hyperparasites attacked uredia of the pathogen and hindered development of the uredia and release of the uredispores.Hyperparasitism of C.phellodendri began between the end of July and early August and then peaked in the middle of September.The natural hyperparasitism was very popular in Ya'an district.In some areas,the percentage of hyperparasitism reached 100%,and the hyperparasitic index ranged from 60 to 100.The hyperparasite was identified as Ramularia sp..The discovery of this hyperparasite might provide potential for biological control. |
