为了探索星点木的大规模繁殖技术，以星点木四年生植株当年生枝条、半年生组培苗枝条和组培试管芽条为试材，研究了不同激素种类、浓度及不同插穗来源对星点木试管外扦插生根的影响。结果表明：星点木试管外扦插生根率较高，生长激素能够很好地促进生根，50 mg?L‐1 IBA处理后生根综合指标较好，生根率可达95％以上，根系效果指数达0．549。半年生组培苗枝条较适合作为插穗来源。

In order to explore the large scale propagation technology for Dracaena godse f f iana ,taking annual shoots from four year old plant ,half‐year‐old branches of tissue culture plant and tissue culture plantlets as ex‐perimental materials ,the effect of different hormones and cuttings on cutting rooting of Dracaena godsef f iana using mnoecious bub outside tube was studied .The results showed that hormones could promote rooting well , the root effective index was the highest after 50 mg?L‐1 IBA ,the rooting rate was more than 95 .0% ,the root effective index was 0 .549 .Half‐year‐old branche of tissue culture plant was more suitable for cutting .
