The optimal rooting medium was MT (Murashige and Tucher) medium added with Img/L NAA (naphthaleneacetic acid) or IBA (indolebutyric acid). A highest rooting rate as much as 61.9% was achieved after 10 days of culture.

• 根的诱导以MT(Murashige and Tucker)为基本培养基；附加1 mg/L萘乙酸(NAA)或吲哚丁酸(IBA)效果较好；接种10 d；生根率高达61.；9%25。
