| 摘 要： | 油菜愈伤组织在培养中生长34d的增殖量最大，增殖倍数为7．08倍，烯丙基硫苷的含量在第6天最高；外源L-缬氨酸明显促进烯丙基硫苷的积累，其浓度为2和4mmol·L^-1时烯丙基硫苷含量分别达到98．5和97．40mg·g^-1（DW）；蔗糖最有利于油菜愈伤组织的生长和其中烯丙基硫苷的积累，浓度以30g·L^-1。的蔗糖为最佳。

| Abstract: | It was studied by callus culture to accumulation dynamics of sinigrin in rape （Brassica campestris） callus and effects of some exogenous carbon and nitrogen containing compounds on sinigrin contents. The extreme proliferation multiples of callus was 7.08 in the 34th day of culture. The sinigrin content reached to 109.04 mg·g^-1 （DW） in the highest at the 6th day. When the addition concentrations of L-valine were 2 mmol·L^-1 and 4 mmol·L^-1, the sinigrin contents of rape callus were 98.5 and 97.40 mg·g^-1 （DW）, respectively, which were promoted obviously. Sucrose was the optimal carbon source for rape callus multiplication and sinigrin accumulation with the best addition concentration of 30 g·L^-1. |
