摘　　要：以大岩桐叶、顶芽为外植体,研究了NAA,IBA对块茎形成的影响.结果表明:NAA/ IBA组合使用明显优于单独使用,当NAA1.0mg/L+IBA0.5mg/L时叶诱导形成块茎的效果最佳,块茎形成率和块茎直径明显增加;块茎质量明显较顶芽块茎诱导好.Effects of test-tube tubers of S. speciosa with leaf and shoot as explants were studied using different concentration of NAA and IBA. The results indicated that the effects of combination of NAA and IBA were superior to the independency usage ,the best medium of induced test-tube tubers was 1/2MS ＋ NAA1.0mg/L ＋ IBA0.5mg/L. The rate and the quality of test-tube tubers with leafs were much better than that of shoots.
