| 摘 要： | 对烟草内生细菌的来源、数量动态变化、与青枯病抗性的关系,以及内生细菌防病和促进种子萌发等方面进行了研究。结果表明烟草内生细菌可来源于种子内部,在烟草不同生育期,抗病品种中内生细菌的总数量以及对青枯病菌具有拮抗作用的内生细菌数量均高于感病品种,部分内生细菌具有促进烟草种子萌发和防治烟草青枯病的作用。

| Abstract: | The origin and dynamic amount changes of endophytic bacteria in tobacco were studied as well as their relation with resistance to Ralstonia solanacearum and effect on controlling tobacco bacterial wilt and seeds germination.Results showed that endophytic bacteria may origin from tobacco seeds.The amount of endophytic antibiotic bacteria in resistant variety was greater than that in susceptible variety in different tobacco growing period.Some endophytic bacteria can stimulate tobacco seeds to germinate and prevent tobacco bacteria wilt. |
