摘　　要：对红叶石楠芽的增殖和根的分化进行了研究,实验结果表明：红叶石楠芽增殖的最佳培养基为MS+2．0mg/L BA+0．5mg/L KT+0．2mg/L IBA,最佳增殖区段为基部,根的分化以NAA预处理2h和3%蔗糖浓度为佳．Phtiniafraseri ＂Red Robin＂ is a tree which comes from overseas. In this paper,the methed is set up through researching the effects of different culture mediums on Phtiniafraseri ＂Red Robin＂in vitro. The results show that the proliferation efficiency of shoots in MS medium additioned 2.0 mg/L BA ＋ 0.5mg/L KT ＋ 0.2MG/L IBA is best. The bottom of segment is much better than the top segmen,it grows healthy through green leaves. Having 2 hours NAA pretreatment make the plant grow best and its rooting efficiency is 70%. The plant longs up to 2.85cm and grows healthy. And the best sucrose concentration is 3%.
