ObjectiveThe aim was to study the dynamic changes of composition content and growth of Dendrobium officinale Kimura et Migo test-tube plantlet in different planting month.

目的研究不同种植月龄铁皮石斛(Dendrobium officinale Kimuraet Migo)试管苗生长及成分含量变化动态。

In vitro micropropagation is a major way for massive production of plantlets of Dendrobium officinale. The ultimate success of this plantlet production undoubtedly depended on the survival and vigorous growth during and after transplantation.

组培快繁是目前铁皮石斛种苗生产的主要途径,组培苗移栽成活率和后期生长势是决定组培快繁生产种苗是否取得最后成功的关键环节。

Regeneration plantlet could obtain from maturation somatic embryo in the medium of non-plant growth regulator. At present, regeneration plantlets of shuidong and feizixiao had been obtained.

4．经过成熟老化的体胚可在无植物生长调节剂的培养基上再生植株，现已得到水东和妃子笑两个品种体胚的再生植株。
