| 中文摘要: |
| 从茄子、番茄、辣椒、烟草青枯病株中分离出116株无致病力青枯菌,室内平板喷雾法拮抗试验结果表明,有21株菌在NA培养基上可明显抑制青枯菌TbRs的生长;烟草MSK326品种温室盆栽控病试验表明,Tmjd1-3和Aujd8-2-1两株菌具有较好控病效果,20 d后的相对防效分别为58.4%和97%。 |
| 英文摘要: |
| A total of 116 avirulent strains of Ralstonia solanacearum were obtained from the stems of eggplants,tomatos,capsicum and tobacco that were affected by this pathogen.In vitro antagonistic assay by spraying indicated that 21 of the strains significantly inhibited the growth of R.solanacearum TbRs on NA media.In a disease-control experiment with tobacco MSK326 carried out in greenhouses,two isolates(Tmjd1-3 and Aujd8-2-1) gave satisfactory results,with 58.4% and 97% relative control rates,respectively. |
