摘要
自发突变的无致病力番茄青枯菌株Tm3具有产生细菌素的能力，对番茄青枯菌株Tm46有较强的抑菌作用，且能诱导烟草植株产生过敏性反应．盆栽和小区试验结果表明，Tm3具有较好的防治番茄青枯病的能力．
The avinilent and bacteriocinogenic strain Tm3 of Ralstonia solanacearum had inhibiting effect on tomato virulent strain Ttn46 and could induce hypersensitive response(HR) in tobacco plants. ItS ability to protect tomato plants from bacterial wilt was investigated in greenhouse and the results indicated that strain Tm3 had a good effect on the biological control of tomato bacterial wilt. The possible mechanisms for the protechon were both antibiosis of bacteriocin and induced resistance of hosts.
