为了对转基因植物的生态安全性研究提供依据，采用土壤梯度稀释法对转基因毛白杨和非转基因毛白杨根部微生物数量的季节变化趋势进行研究。结果表明：转基因毛白杨根际、根表和根皮3个层面的根部细菌数量变化均是春季较少，夏季有不同程度的增多，秋季减少，根内的细菌数量极少；非转基因毛白杨根际细菌数量的变化表现为春季较少，夏季增多，秋季减少；根表和根皮则表现为春季到秋季细菌数量呈下降趋势。转基因毛白杨根部真菌数量变化趋势均为春季较少，夏季有不同程度的增多，秋季减少；非转基因毛白杨根部真菌的数量为从春季到秋季呈逐渐减少的趋势。

The seasonal variation trend of soil microbial quantity around roots of transgenic and common P .tomentosa was studied by soil gradient dilution method to provide the scientific basis for ecological safety of transgenic plants.The bacterial quantity of rhizosphere,root surface and root bark of transgenic and common P .tomentosa has slight change in spring,increases to varying degrees in summer and decreases in august,and there is little bacterial quantity in endophytic root.The bacterial quantity of root surface and root bark shows a decline trend from spring to august.The fungal quantity around roots of transgenic P .tomentosa has slight change in spring,increases to varying degrees in summer and decreases in august but the fungal quantity around roots of common P .tomentosa shows a gradual decline trend.
