| 摘 要： | 本文报道对寄生菟丝子的两个炭疽菌(Colletotrichum Corda)分离系(鲁保一号New-76)的鉴定结果。两分离系按其培养特性、分生孢子和附着孢的形态、大小及产孢细胞、分生孢子盘的特点,应属于胶孢炭疽菌Colletotrichum gloeosporioides(Penz.)Sacc.],但在对寄主的选择性方面不同于该种的其他分离系,特别是对菟丝子(Cussuta chinensis)具有寄生专化性,故确定为胶孢炭疽菌菟丝子专化型C.gloeosporioides(Penz.)Sacc.f.sp.cuseutae]。

| Abstract: | Two isolates Colletotrichum Cda. on Cuscuta sp. and C. chinense were isolated from Jinan and Wuchang and have been used as biocontrol agents of dodder succesfully in China for many years. They resemble each other and are identical to Colletotrichum gloeosporioides (Penz.) Sace. morphologically. They can be distinguished from other isolates of C. gloeosporioides (Penz.) Sacc. isolated from apple, grape, Ficus elastica, Olea europea and Citrus spp. etc. by the test of host reaction. The dodder isolates are parasitic on Cuscuta chinensis and cause anthrocnose, while the others do not. They were determined as Colletotrichum gloeosporioides (Penz.) Sacc. f. sp. cuscutae. |
