| 摘 要： | 以常规大豆品种中黄13为对照，研究了抗草甘膦转基因大豆AG5601对根际土壤可培养微生物的数量影响。经过大豆2个生长周期的研究发现：在相同时段内，转基因大豆AG5601和对照对根际土壤细菌、真菌和放线菌的数量变化影响趋势基本一致；除在第2生长周期的第30～100天（20100618～20100908）时转基因大豆极显著地抑制了根际土壤真菌数量（p<0.01）外，转基因大豆对根际土壤微生物数量的影响呈不规律变化；转基因大豆对根际土壤微生物有一定的影响，但无明显规律可循。此研究结果为在我国南繁地区开展转基因大豆AG5601安全评价提供数据支持。 |

| Abstract: | Taking Zhonghuang-13 soybean as the control, the influence of Roundup Ready(RR)soybean AG5601 on the rhizosphere microorganisms was studied in the Plant Breeding Base of Hainan. After 2 planting cycles' practice and experiment, it was found that the changes of bacteria, fungi, and actinomycetes were roughly with the same trends in rhizospheres oil of RRS and the control. Irregular changes of the RRS influence on rhizosphere soil microbes was found except that the number of fungi in the rhizosphere soil was obviously reduced by RRS(p<0.01)in 30 d to 100 d in the second planting cycle. The results would be useful for the safety assessment of GM soybeans at the Plant Breeding Base of Hainan. |
