This study was conducted to establish the tissue culture system for Atractylodes plant which is most frequently used in oriental medicine. Root and auxiliary bud of Dachul cv., which is Atractylodes hybrid (A. macrocephala x A. japonica), were used as target tissues for in vitro culture. In root culture, callus induction rate was higher in the treatment of BAP combined with NAA than others, however, 2-iP was more effective for callus proliferation and root induction. Although calli were effectively induced from the root and proliferated in lower concentration of cytokinin combined with higher auxin, root tissue was inappropriate for shoot regeneration. For plant regeneration with axillary bud, BAP combined with NAA was more effective than 2-iP with NAA or IBA. Number of regenerated plant per bud was 3.8, which was highest, and stem diameters was shown as 5.0mm under the conditions of 1 mg/L BAP combined with 1 mg/L NAA. Although, plant height was tend to be higher in 2-iP than BAP, number of the regenerated plant was lower via versus. Furthermore, root proliferation of regenerated plant was more effective in higher concentration of sucrose (7%) than in lower concentration (3%). In results, auxiliary bud was an efficient target tissue for producing regenerated plant of Atractylodes under the conditions of 1 mg/L BAP combined with 1 mg/L NAA and higher concentration of sucrose was effective for root proliferation of regenerated plants.
