| 摘 要： | 2007年8月至2008年9月在黑龙江省哈尔滨、齐齐哈尔、牡丹江、佳木斯、黑河、五大连池等大豆产区采集大豆根腐病病株42株,共分离获得362株镰孢菌。通过纯化培养和形态学鉴定,确定它们属于8种镰孢菌,其中F.oxysporum和F.solani的分离频率最高,分别为15.24%和16.90%。并对这8种镰孢菌的形态学特征进行了描述。

| Abstract: | During August, 2007 to September, 2008, total 42 root-rot soybean plants were collected in the soybean growing areas of Harbin, Qiqihar, Mudanjiang, Jiamusi, Heihe and Wudalianchi of Hei-longjiang Province, from which 362 strains of Fusarium species were isolated. Based on morphological characteristics, these strains were identified as eight species of Fusarium. Among them, Fusarium oxysporum and F. solani were predominant population with the highest isolation rate of 15.24% and 16.90%, respectively. This p... |
