吉林省甜菜发现有四种细菌病害,其中两种为叶斑病、两种为根病。经对其症状观察和病原细菌的分离、致病性测定,细菌的形态、培养性状、生理生化等系统鉴定,确认两种叶部病害为甜菜细菌性斑点病Pseudomonassyringae pv.apiata(Brown and Jamieson)Young et al和甜菜细菌性叶斑病Curtobacterium flaccumfaciens pv.betae(Keyworth Howell andBowson)Collins and Jones.两种根病为甜菜根癌病Agrobacterium tume-faciens(Smith and Townsend)Conn.和甜菜根软腐病Erwinia Caroto-vora subsp.Carotovora(Jones)Bergey et al.
There are four bacterial diseases found in sugar beet in Jilin Province, of which two are leaf spot disease and two are root disease. Pseudomonas syringae pv. Apiata (Brown and Jamieson) was identified as a disease of beet bacterial blight after its symptom observation and isolation of pathogenic bacteria, pathogenicity test, bacterial morphology, culture traits and physiological and biochemical characteristics. Young et al and beet bacterial leaf spot Curtobacterium flaccumfaciens pv.betae (Keyworth Howell and Bowson) Collins and Jones. Both root diseases are beet root cancer Agrobacterium tumefaciens (Smith and Townsend) Conn. And beet soft rot Erwinia Caroto-vora subsp. Carotovora (Jones) Bergey et al.
