【摘要】 为了评价转基因玉米对土壤环境生态安全风险,通过盆栽试验,以转Bt基因P1498及非转基因亲本Non-Bt P1498,转抗除草剂基因C31为材料,研究比较转基因玉米不同生育期对土壤微生物的影响。结果表明,转基因玉米对土壤细菌没有显著影响;土壤真菌在苗期有显著影响,其他生育期没有影响;放线菌在抽雄期有显著影响,其他生育期没有影响;转基因玉米对土壤氨化细菌、好气性固氮菌没有影响。说明转基因玉米对土壤微生物数量没有显著影响。更多还原

【Abstract】 The experiments were conducted to assess effects of transgenic corn on soil microbes in pot cultivation condition in Yuncheng city, Shanxi province. Transgenic Bt corn hybred P1498 and near-isogenic Non-Bt P1498 line, and transgenic herbicide tolerant corn C31 were used in 2014. The results showed that there were no significant differences in soil bacteria, ammonifying bacteria,and aerobic azotobacter between transgenic and conventional corn cultivars during different growth stages. Compared with conventional cultivar, transgenic corn only had district differences on soil fugal population at seedling stage and actinomycetes at silking stage. This indicated that transgenic corn did not affect soil microbal population.更多还原
