1.1963年黑龙江省绥化、嫩江等县内发生了显著的大豆苗期病害,造成了大量缺苗和幼苗枯死。2.由于枯病苗的根部、茎基部黑褐色病斑上分离出一种镰刀菌,经过土壤接种,认定该菌有引致同种病害的病原性,为害损失率可达35%,致病作用为侵害种粒和大豆幼苗的根、茎靱皮部。3.用单一胞子系作览定培养的结果,初步肯定该菌为 Fusarium avenaceum(F.r.)Sacc.var.herbarum(Cda.)Sacc.。
1. In 1963, significant soybean seedling disease occurred in Suihua and Nenjiang counties in Heilongjiang Province, causing a large number of seedlings and seedlings to die. 2. As a result of the seedling root blight, stem base dark brown lesions isolated a Fusarium, after soil inoculation, that the bacteria have caused the same disease pathogenic, damage loss rate of up to 35%, pathogenic role In order to infringe the seeds and soybean seedling roots, stems and skin Department. 3. With a single cell line as a result of scheduled culture results, initially identified as Fusarium avenaceum (F.r.) Sacc.var.herbarum (Cda.) Sacc ..
