The response of antioxidant enzymes and quality of three soybean varieties to Mo and/or B in soil has been studied in this paper. Pot experiments were set up with four treatments (control, +Mo, +B, +[Mo + B]) at four growth stages. The study showed that Mo and/or B increased antioxidant enzyme activities and protein content in the seeds. The variation and interaction between Mo and B in soil was explored with regard to their impact on the soybean quality. The Mo and/or B decreased oil-content, linoleic and linolenic acid and thus improve plant quality for human health. There were some dissimilarity in antioxidant enzymes and quality of plant between supplement of Mo and B in the soil, and the interrelation between Mo and B in the plant was co-supplementary to each other. Therefore, the quality of the soybean with Mo and B treatments was much improved than those with Mo or B alone. The study shows that the quality of soybean seeds has some stability as compared to physiological and growth characteristics of vegetative organs.Keywords:
