摘要
从山东莱阳苹果园的苹果冠瘿瘤中分离到 18株根癌土壤杆菌。经过鉴定有 3株是Agrobacterium tumefaciens(原生物 1型 ) ,其余 15株是 A. rhizogenes(原生物 2型 )。这些菌株所诱导的冠瘿瘤中均能合成胭脂碱 ( nopaline) ,属于胭脂碱型 Ti质粒的根癌土壤杆菌。通过室内平皿检测发现 ,分离到的菌株均对 K84菌株所产生的土壤杆菌素敏感。在温室指示植物向日葵幼苗上 K84和K10 2
Eighteen strains were isolated from crown galls of apple in Laiyang of Shandong Province. The identification indicated that three of them were A. tumefaciens (Biotype 1 formerly); the others were A. rhizogenes (Biotype 2 formerly). All strains carry nopaline type Ti plasmid and were sensitive to agrocin 84. The result of inoculation on sunflower stems in green house indicated that K84 and K1026 could inhibit the development of tumors.
