病原菌菌株对放射土壤杆菌K—84产生的细菌素敏感。但各菌株间敏感性的强弱不一。用K—84在温室对番茄做生防试验表明。以1:1(拮抗菌:病原菌的)比例混合接种在番茄上。敏感性强的致病菌株不产生瘿瘤。而敏感性弱的菌株需用2:1才不产生瘿瘤。
Pathogenic bacteria strains are sensitive to bacteriocins produced by Agrobacterium tumefaciens K-84. However, the sensitivity of different strains vary. The biocontrol test of tomato with K-84 in the greenhouse showed. To 1: 1 (antagonistic bacteria: pathogenic bacteria) were inoculated on the tomato inoculation. Sensitive pathogenic strains do not produce gall tumor. The weak sensitivity of strains required 2: 1 do not produce gall tumor.
