| 摘 要： | 以4年生转双抗虫基因741杨试验林为对象,研究了土壤中Bt毒蛋白的分布,及其在生长季节中土壤微生物种群数量的变化.结果表明:试验林土壤中发现了毒蛋白的存在,在转基因植株根围含量最高,距根系越远,含量逐渐降低.其毒蛋白分布趋势是根组织＞根际土壤＞根围土壤＞地表土,其浓度一般呈10倍的等级降低,在非转基因对照植株根系周围未...

| Abstract: | In order to evaluate ecologic safety of transgenic insect-resistance hybrid poplar 741,the diversity of soil microflora and Bt toxin protein were systematically studied in the growth season.4-year-old transgenic poplar 741 in the Heneshui district and Baoding district were examined.The toxin protein was found in the soil of 4-year-old test groves,whose peak content appeared in rhizosphere,and the longer the distances off the roots,the lower the contents.The distribution of toxin protein showed a descending ... |
