使用苯甲酰胺和EMS单因子和复因子处理大麦风干种子。结果表明,苯甲酰胺和EMS复合处理,与二者单因子处理相比,抑制苗高的效应明显,诱发的染色体畸变率较高,对发芽率也有明显影响。上述现象随甲苯酰胺浓度增加而明显增强, 表明苯甲酰胺能对EMS所造成的DNA损伤的修复产生抑制作用。 Barley air-dried seeds were treated with benzamide and EMS uniforms and complexing factors. The results showed that the combination of benzamide and EMS could significantly inhibit the height of seedling compared with the single factor treatment, and the chromosome aberration induced rate was high, which also had a significant effect on the germination rate. The above phenomenon was obviously enhanced with the increase of toluamide concentration, indicating that benzamide can inhibit the repair of DNA damage caused by EMS.
