摘　　要：以竹叶兰种子为外植体进行无菌播种,成功诱导原球茎并再生植株,建立其快繁体系。试验结果表明:(1)1/2 MS+香蕉泥30.0 g/L为最佳种子萌发与原球茎诱导培养基;(2)1/2 MS+6-BA 1.0 mg/L+NAA 0.1mg/L+香蕉泥30.0 g/L为最佳芽增殖培养基,且芽生长健壮;(3)1/2 MS+IBA 0.5 mg/L为最适生根培养基。Seeds of Arundina graminifolia （D. Don） Hochr. was used as explants for aseptic sowing and inducting of PLBs and plantlet regeneration. The results showed that the best medium for germination of seeds and PLBs induction was 1/2 MS with 30 g/L banana. The optimum medium for multiplication was 1/2 MS supplemented with 1.0 mg/L BA ＋0.1 mg/L NAA＋30 g/L banana, increasing the growth of shoots. The suitable medium for rooting was 1/2 MS with 0.5 mg/L IBA.
