| 摘 要： | 以扁穗牛鞭草茎段为外植体，进行组织培养体系研究，结果表明：初代培养最佳配方为MS＋6-BA1．0mg／L＋NAA0．1mg／L，芽诱导率可达100％；继代增殖最佳增殖配方为MS＋6-BA1．5mg／L＋NAA0．2mg／L，增殖系数为5．4；生根阶段以1／2MS＋IBA0．2mg／L为最佳的生根培养基配方，生根效果最好，生根率最高；初代培养生根苗与增殖后生根培养苗移栽成活率都在97％以上。

| Abstract: | The stems were used as explants to establish the system of tissue culture for Hemarthria compressa.The result showed that: MS 6-BA1.0mg/L NAA0.1mg/L gave rise to the best result in inducing adventitious buds from explants,in which the inducement rate could be 100%,and MS 6-BA1.5mg/L 0.2mg/L NAA was favorable to the proliferation of buds,in which the multiplication rate could be 5.44.The rooting rate could be 100% on 1/2MS IBA 0.2mg/L.Both survival rates of adventitious buds and proliferation buds were higher than 97%. |
