摘要
对影响大豆外源 DNA导入成活率诸多因素进行了探讨 ,结果表明 ,适当的 DNA导入时间、正确选择导入花部位、适量的柱头切取、适宜的土壤水分及疏花疏荚都可显著提高 DNA导入成活率 ,成活率最高为 49% ,平均为 34.3%
The paper researched the factors influencing the survival of immature pods of soybean in total DNA introduction through the pollen tube. The result showed that the time of DNA introduction, the position of flowers, the depth of stigma-cut, the content of soil water and the density of flowers and pods on other nods all influenced the survival of the immature pods. The highest rate of survival was 49% in the experiment, and 34.3% in average.
