摘要
以点地梅幼苗为外植体进行快速繁殖,分别诱导、分化、生根形成再生植株进行快速繁殖,并移栽成活。结果表明,在MS+6-BA(3mg/L)+NAA(0.5mg/L)培养基上诱导丛生芽效果最佳。在MS+NAA(0.4mg/L)培养基中根的诱导率为100%。
A successful micropropagation technique of Androsace umbellata （ Lour. ） Merr. has been estab- lished from the explants of seedlings. The result shows that： （ 1 ） MS mediums, with 0.5mg/LNAA and 3.0rag/ LBA, could promote the growth of vegetative auxiliary buds and regeneration of plentiful lateral buds; （2） Shoots derived from auxiliary and lateral buds could form roots on MS medium with 0.4 mg/LNAA, and the rate of the inducement in the medium is up to 100%.
