怀山药带节茎段在 ＭＳ＋６－ＢＡ １～２ｍｇ／Ｌ＋ＮＡＡ ０．１～１ｍｇ／Ｌ的培养基上培养，均能直接形成多芽体，均芽数为 ３～５。将多芬体转入ＭＳ或 ＭＳ＋ＫＴ ２ｍｇ／Ｌ＋ＮＡＡ ０．０２ ｍｇ／Ｌ＋ＰＰ_３３３ ０．１ｍｇ／Ｌ的培养基上均能诱导生根，形成再生植株。但后者形成的苗生长健壮，叶色浓绿，有较强的生活力。
The stem segments of Huayuang medicinal plants can be directly cultured in the medium of MS + 6-BA 1 ~ 2mg / L + NAA 0.1 ~ 1mg / L with the number of buds 3 ~ 5. The introduction of Dauphora into MS or MS + KT 2mg / L + NAA 0.02 mg / L + PP_333 0.1mg / L medium can induce rooting, the formation of regenerated plants. However, the formation of seedlings grow robust, dark green leaves, a strong vitality.
