风信子外植体植株再生系统的研究

STUDY ON THE REGENERATION OF EPLANTS OF HYACINTH

风信子叶片及鳞片直接诱导不定芽的培养基为ＭＳ附加６－ＢＡ２．５ｍｇ／Ｌ、ＮＡＡ２．０ｍｇ／Ｌ、ＩＡＡ０．５ｍｇ／Ｌ和ＭＳ附加６－ＢＡ２．５ｍｇ／Ｌ、ＮＡＡ２．５ｍｇ／Ｌ．不定芽发育成小鳞茎的培养基为ＭＳ附加ＧＡ０．２ｍｇ／Ｌ、ＩＡＡ０．５ｍｇ／Ｌ．鳞茎移栽成活率为９０％．

Adventitious shoots are induced directly from leaves and scales without callus in MS+BA2.5 mg/L+NAA2.0 mg/L+IAA0.5 mg/L and MS+BA2.5 mg/L+NAA2.5 mg/L.The shootlets develop into the bulbets in MS+GA0.2 mg/L+IAA0.5 mg/L.The survival rate of bulblet transplantion is 90%.Thus the regeneration system of hyacinth is established.
