地面(出苗前)或植株(幼苗分枝期)喷施Atrazine液后,从田间观测及考种结果看,未导入抗性基因的大豆对照株受害严重,或枯死或严重减产;导入抗性基因的大豆植株后代F_4、F_5代基本不受影响,单株产量与未喷液的对照株相近或略高。这显示了导入的抗性基因对Atrazine的抵抗作用。通过喷施Atrazine已筛选出了多个抗性较强的株系,有望从中进一步筛选出抗性稳定的株系,用到大田生产。 After the Atrazine solution was sprayed on the ground (before emergence) or the plant (seedling branching period), the soybean control strain not introduced with the resistance gene was seriously damaged, or died or severely reduced from the field observation and test results. The resistance gene Of the offspring of soybean plants F_4, F_5 generation basically unaffected, the yield per plant and non-sprayed control plants similar or slightly higher. This shows the resistance of the introduced resistance gene to Atrazine. By spraying Atrazine has screened a number of more resistant strains, is expected to further screen out the stable strains of resistance, used in field production.
