生物量较高的生物群3 OFA。TumefaciensandA.从有冠瘤的葡萄根部分离到的放射菌比从未感染的葡萄根部或从感染和未感染的葡萄园采集的非根际土壤中分离到的放射菌更多。非葡萄园土壤连续稀释培养在选择性培养基上未检测到Biovar 3，表明生物量为100-1000cfu/g土壤。从苗圃采集的看似健康的砧木和未嫁接的葡萄品种的根被致瘤生物3和非致癌生物3污染。当对特定的根部切片进行生物量3检测时，主要从根部的小的、黑暗的、凹陷的病斑中分离出生物量3。
Higher populations of biovar 3 ofA. tumefaciensandA. radiobacterwere isolated from roots of grapevines with crown gall than from roots of noninfected vines or from nonrhizosphere soils sampled from infected and noninfected vineyards. Biovar 3 was not detected by plating serial dilutions of nonvineyard soils on a selective medium, indicating that populations were < 100-1000 CFU/g soil. Roots of apparently healthy rootstocks and nongrafted grapevine cultivars sampled from nursery storages were contaminated with tumourigenic and nontumourigenic biovar 3. When specific sections of roots were assayed for biovar 3, it was predominantly isolated from small, dark, sunken lesions on the roots.
