太子参壮苗生根及驯化移栽技术研究

本试验旨在优化太子参壮苗生根和驯化移栽技术。试验以MS为基础培养基，添加NAA、6-BA和马铃薯淀粉，采用L94(3)设计进行壮苗生根试验，不同配比基质进行栽移试验。通过以MS+蔗糖30 g/L为基础培养基，调节pH5.8，添加NAA 0.1、0.3、0.5 mg/L，6-BA 0、0.5、1.0 mg/L和马铃薯淀粉0、10、20 g/L进行研究，当基础培养基+NAA0.3 mg/L+6-BA0 mg/L+马铃薯淀粉10 g/L时诱导生根数最高，平均达26.125；不同移栽基质对太子参移栽成活率的影响较大，采用全腐殖土和腐殖土50%+珍珠岩50%作为移栽基质，成活率分别达97.5%和92.5%。

Rooting Culture and Training Transplant Technique of Pseudostellaria heterophylla Miq.

In order to optimize the seedling rooting and transplanting techniques of domestication of Pseudostellaria heterophylla in this study, test based on MS culture medium, adding NAA, 6-BA and potato starch, used L94（3） orthogonal test on seedling rooting and transplanting of different substrates. MS culture medium＋sucrose 30 g/L as basic culture medium and pH 5.8, added NAA 0.1, 0.3, 0.5 mg/L, 6-BA 0, 0.5, 1 mg/L and potato starch 0, 10, 20 g/L were studied, the highest average root 26.125 was induced by the basic culture medium＋NAA 0.3 mg/L＋6-BA 0 mg/L＋potato starch 10 g/L. Different soil substrates were effecting on survival rate of transplanting of Pseudostellaria heterophylla, using humus soil and humus soil 50% ＋ perlite 50% as substrates, the survival rates were 97.5% and 92.5%.
