摘　　要：以油菜为试材,研究不同浓度的油菜素内酯、拉肖皂苷元(La)及其糖苷C-拉肖皂苷C(LG-C)对油菜种子萌发及幼苗生长影响。结果表明:随处理浓度不同,油芽种子萌发及幼苗生长有差别,其中浓度为0.05 mg/L拉肖皂苷C对种子萌发和幼苗生长有明显的促进作用,处理后的油菜幼苗干鲜重增加;且这3种化合物均呈现出低浓度促进,高浓度抑制油菜生长趋势,表明适度的激素处理有利于油菜生长和代谢。Taking rape as test material,effects of different concentrations Brassinolide and Laxogenin and Laxogenin C on seed germination and seedling growth of rape were studied.The results showed that the different concentrations had different seed germination and seedling growth of rape,particularly at a concentration of 0.05 mg/L of Laxogenin C.Laxogenin C increased the dry weight and fresh weight of leaf and all of these hormones have presented that low concentration increased the growth and high concentration inhibited the growth of rape.This showed that appropriate hormone treatment may help rape seedlings to grow and metabolize.
