摘　　要：１９９０年在山东沂南县调查发现烟草枯萎的病株，分离到细菌菌株。经对各菌株致病性测定．格兰氏染色反应，细菌形态，培养性状，生理生化测定和血清学反应鉴定，结果表明这５个菌株均属于青枯假单胞杆菌ＰｅｓｕｄｏｍｏｎａｓｓｏｌａｎａｃｅａｒｉｕｍＥ．Ｆ．Ｓｍｉｔｈ。Bacteria wilt usually occurs in the south of China. It was found in tobacco plants in Shandong Province in 1990. This paper studies the occurrence status and difference between Shandong and other areas in pathological and bacteriolical properties.Five bacterial strains isolated from wilt tobacco plants in Yinan country, Shandong Province were indentified as Pseudomonas solanacearium E. F. Smith based on pathogenicity, Gram Stain, morphology, culture characteristic, physiological chemistry and serology.
