title: [Tissue culture and plant regeneration of Rhodiola henryi].
abstract: OBJECTIVE
  To study the tissue culture and plant regeneration technologies and optimizing propagation system in vitro of Rhodiola henryi.
  
  
  METHODS
  Orthogonal experiment designs were used in the study of Rh. henryi callus induction, shoot formation and rooting, and the data were analyzed by range analysis and variance analysis.
  
  
  RESULTS
  The optimal media to induce multiple callus from leaves were MS supplemented with 2,4-D 1.5 mg x L(-1) and 6-BA 0.5 mg x L the effect of the three factors was in sequence of explants > 2,4-D > 6-BA; The optimal media to induce multiple buds from stems were MS supplemented with 6-BA 1.5 mg x L\/1-1 NAA >6-BA; Plantlets were rooted on 1/2MS supplemented with IBA 1.0 mg x L-1, and rooting rate reached to 90% or more and transplant survival rate of plantlet reached 98% or more.
  
  
  CONCLUSIONS
  An efficient system for tissue culture and plant regeneration of Rh. henryi was initially established.
