| 摘 要： | 通过分离计数以及运用分子生物学手段,研究了吴凤实验基地不同种植年份转BT基因水稻对水稻土壤的功能群氨氧化细菌的影响.查明种植转B t基因水稻会影响其根际浅层的可培养氨氧化细菌种群组成.这种影响表现为:种植转B t基因水稻的时间越长,种植的强度越大,对土壤氨氧化细菌的影响也就越大,这一现象从A、B、E土样的对比和B、D、E土样的对比中得到明显的反映.同样,转B t基因水稻也会影响到土壤深层的氨氧化细菌,与浅层土样中的结果具有相似性.

| Abstract: | Four kinds of rhizosphere soil collected from WuFeng experiment station were used to study the community composition of Ammonia-Oxidizing Bacteria(AOB) by using separating-counting method and molecular biology method.Planting Bt-transgenic transgenic rice does affect its shallow rhizosphere AOB composition.For planting Bt-transgenic rice,the longer the time of cultivation and the greater intensity of cultivation,the greater influence on its rhizosphere AOB.It could be found by comparing soil examples A/B wi... |
