摘要
为明确宁夏引黄灌区春大豆炭疽病病原菌的种类,采用形态学分类法鉴定了宁夏引黄灌区春大豆炭疽病的病原。结果表明:宁夏引黄灌区春大豆炭疽病危害症状、病原菌的菌落特征、病原菌的形态特征与大豆平头炭疽菌Colletotrichum truncatum一致;致病性测试结果表明供试大豆炭疽病菌菌株均具有较强的致病性,人工接种后病害症状与田间病害症状基本一致,再采集分离获得病原菌,其与接种的大豆炭疽病菌形态特征一致;说明大豆平头炭疽菌Colletotrichum truncatum是导致宁夏引黄灌区春大豆炭疽病的病原菌。
In order to clarify the species of pathogenic bacteria of spring soybean anthrax in Ningxia Yellow River irrigation area, the pathogen of spring soybean anthrax in Ningxia Yellow River irrigation area was identified by morphological taxonomy. The results showed that the harmful symptoms, colonial characteristics and morphological characteristics of pathogenic bacteria of spring soybean anthrax in Ningxia Yellow River irrigation area were consistent with those of Colletrichum truncatum. The results showed that the tested strains of soybean anthrax had strong pathogenicity. The symptoms of the disease after artificial inoculation were basically the same as those in the field. The morphological characteristics of the pathogens obtained from the collection and isolation were the same as those of the inoculated strains. It indicated that Colletrichum truncatum was the pathogen causing anthrax of spring soybean in Ningxia Yellow River irrigation area.
