【摘要】 <正> 兰科植物铁皮石斛(Dendrobium candidum Wall.ex Lind1.)的茎为常用名贵中药。多年来,主要依靠采收野生品种供药用和出口,致使野生资源枯竭,现已成为日益稀少的濒危植物。兰属种子和石斛属种子试管繁殖已积累不少资料,但是有关铁皮石斛种子试管繁殖的研究只有少量简单的报道,对其种子在试管繁殖过程中,所需外界条件的研究也不够更多还原

【Abstract】 The seeds of Dendrobium candidum germinated easily on medium (1/2 MS) without NAA and BA. The embryo germination and the derivation of protocorm were promoted when NAA or potato extract was added to the medium. However, the proliferation and growth of protocorm were inhibited when BA or NAA+BA was added in the medium.The aqueous extract of banana or potato and the alcoholic extract of Quercus glauca bark apparently accelerated the plantlets regeneration and rooting.更多还原
