摘要： 在MS中加入不同浓度的BA和NAA，配置成7种培养基，对杭白菊进行茎尖培养。结果表明，较高浓度的BA和较低浓度的NAA有利于芽的诱导，其中以MS+BA2.0mg/L+NAA0.1mg/L诱导芽的效果最好；较低浓度的BA和较高浓度的NAA有利于根的诱导，其中以MS+BA0.1mg/L+NAA1.0mg/L诱导芽的效果较好；以不加植物生长调节物质的MS诱导的根量最大，但根较细。

Abstract: The shoot of Hangzhou White Chrysanthemum was cultured in seven kinds of MS media with different amount of BA and NAA. The results showed that a larger amount of BA and less amount NAA benefit to the induction of shoots, and a less amount of BA and larger amount of NAA benefit to the induction of roots. Among them, MS+BA2.0mg/ L+ NAA0.1mg/L is the best to induce the shoots and MS+ BA0.1mg/ L+ the NAA1.0mg/ L is optimal to induce the roots, and the largest number of roots was produced in MS medium without hormones, but the roots are fine and long.
