本试验用苯甲酰胺、￣（６０）Ｃｏγ射线、电子束单因子及苯甲酰胺与￣（６０）Ｃｏγ射线、电子束复因子处埋大豆风干种子。结果表明，苯甲酰胺单因子处理，对大豆Ｍ１的苗高、成株率、孕性和根尖细胞染色体均无明显的影响，对其Ｍ２也无诱变效应。￣（６０）Ｃｏγ射线、电子束单因子处理，对大豆具有明显的损伤效应和诱变效应。苯甲酰胺与￣（６０）Ｃｏγ射线或电子束复因子处理，能明显增强Ｍ１的损伤效应，并能提高Ｍ２的诱变效应。苯甲酰胺具有抑制辐射损伤修复、提高诱发突变频率的作用。
In this experiment, benzamide, ¯ (60) Coγ-ray, electron beam single factor and benzamide and ¯ (60) Coγ-rays were used to dry seeds of soybean embedded in complex factor of electron beam. The results showed that the single factor treatment of benzamide had no obvious effect on the seedling height, adult plant rate, fertility and root tip cell chromosome of soybean M1, and had no mutagenic effect on M2. ¯ (60) Coγ-ray and electron beam single factor treatment have obvious damage effect and mutagenic effect on soybean. Benzamides and ~ (60) Coγ-ray or electron beam complex factor treatment can significantly enhance the damage effect of M1 and enhance the mutagenic effect of M2. Benzamide has the effect of inhibiting radiation damage repair and increasing the frequency of induced mutation.
