防治番茄青枯病内生细菌的分离与筛选

Preliminary Report on Isolation and Screening of Endophtic Bacteria to Control Bacterial Wilt of Tomato

从番茄健株根内分离获得内生细菌 ,对其进行平板拮抗番茄青枯菌试验 ,得到 18株拮抗菌。温室控病试验表明 ,0 1 144和 0 1 182号菌株的控病效果分别为 48.6 %和 42 .8%,经鉴定两者均属芽孢杆菌属 (Bacillsspp)。

By successfully isolating endophytic bacteria from roots of healthy tomato, 18 strains could inhibit the growth of Ralstonia solanacearum on plate culture. Greenhouse tests indicated that the diseae-control efficiency of the strains named as 01-144 and 01-182 were up to 48.6% and 42.8% respectively. By bacterial identification,the two strains all belonged to Bacillus spp.
