摘　　要：研究结果表明，咖啡因和苯甲酰胺单因子处理，对大豆Ｍ１代的苗高、成株率、孕性、根尖染色体和过氧化物酶活力均无明显影响；对Ｍ２代也无诱变效应。１３７Ｃｓγ射线单因子对大豆有明显的损伤效应和诱变效应；咖啡因、苯甲酰胺与１３７Ｃｓγ射线复合处理明显增强了Ｍ１...The results of single treatment of caffeine or benzamide to M\-1 soybean are as follows. The seedling height, rate of mature plant, fertility, frequency of chromosomal aberration in root tip cells and activity of POD were obviously affected, and the same results were with M\-2. 137Cs ray had damage and mutagenic effects on soybean. Combined treatment of the three methods enhansed M\-1 damage effect and M\-2 mutagenic effect. By the method of 3HTdR, it was shown that caffeine inhibited the recovery of radiation damage and enforced the damage effect on M\-1 soybean and obviously increased mutagenic frequency of M\-2.
