摘要
BR能明显促进大豆苗期生长, 硝酸还原酶活性也明显提高, 10μg•L-1BR能使大豆株高增加14.7%, 使根的鲜重增加59.3%, 硝酸还原酶活性增加1.1~2.8倍

Abstract:
It was shown that the growth of seedling and the activity of nitrate reductase were increased by 10,30 or 50 μg•L-1 of brassinolide solution. The height of shoot and the fresh weight of root were inhanced by 14.71%and 59.3%, respectively with the treatment of 10 μg•L-1 brassinolide. Whereas the activies of nitrate reductase at different developmental stases were 1.1~2.8 times than that of controls when the seeds were treated with 10,30 or 50 μg•L-1 brassinolide.
