吉林省各地在大豆上出现三种不同症状的细菌病害:一是病斑黄褐色、小型、发亮、边缘是黄色晕圈;二是病斑黑褐色、多角形、边缘是褪绿晕圈;三是病斑暗红褐色、圆形,具泡状突起。经过分离培养获得三种不同的细菌,通过接种证实为各该病原细菌。根据对细菌的形态、生理生化性状等方面的鉴定,结合症状特点,应是Pseudo monas syringae pv glycinea、Pseudomonas syringae pv.glycinea Var japonica和Xanthomonas campes tris Pv.phaseoli var sojense从全省各地发病调查和采集的病害标本,经室内鉴定和致病力测定结果看出,吉林省大豆上发生的细菌病害有三种:细菌性疫病、细菌性斑点病、细菌性斑疹病。
Jilin Province, there are three different symptoms of soybean disease in the bacterial disease: First, the lesion tan, small, shiny, the edge of the yellow halo; Second, the lesion dark brown, polygonal, the edge is chlorotic halo halo; Third, the lesion dark reddish brown, round, with bubbly processes. After isolation and culture to obtain three different bacteria, proved by inoculation of the pathogenic bacteria. According to the morphological, physiological and biochemical characteristics of bacteria identification, combined with the symptoms, should be Pseudomonas syringae pv glycinea, Pseudomonas syringae pv.glycinea Var japonica and Xanthomonas campes tris Pv.phaseoli var sojense from all over the province incidence survey and collection Of the disease specimens, the indoor identification and pathogenicity determination results show that there are three bacterial diseases occurring in soybeans in Jilin Province: bacterial disease, bacterial spot disease, bacterial spot disease.
