采用组织分离法,对樟树(C innam omum camphora)、冬青卫矛(E uonymus japon icus)、柑橘(C itrus reticu lata)3个树种炭疽病进行病原分离,经纯化培养,在此基础上进行寄主接种试验。结果表明,3种炭疽病的病原均为炭疽菌属的胶孢炭疽菌(Colletotrichum g loesporioid es)。3个炭疽菌的分生孢子萌发、附着孢的形态学特征以及纯化培养的菌落均存在一定的差异。致病性测定结果显示,3个菌种分别对同一寄主的致病性存在一定的差异。
The tissue isolation method was used to isolate anthracnose from three species of C innam omum camphora, E uonymus japon icus and Citrus reticu lata. After purification, the host Vaccination test. The results showed that all the three anthrax pathogens were Colletotrichum g loesporioid es. Conidia germination of three anthrax conidia, morphological characteristics of attached spores and purified culture colonies there are some differences. The results of pathogenicity test showed that the pathogenicities of the three strains were different to the same host respectively.
