영문 초록

In this study, a plant tissue culture system was established for Atractylodes spp., an economically valuable medicinal crop in Korea that has low domestic production and is increasingly imported. In particular, Atractylodes ovata was treated with four types of cytokinins, 6-benzylaminopurine (BA), zeatin, kinetin, and thidiazuron (TDZ), in two different concentrations (0.5 and 1.0 mg/L). Among the four types of cytokinins, the BA treatment was effective for the shoot and root growth of A. ovata. Both the 0.5 mg/L and 1.0 mg/L concentrations of BA showed similar results; however, the 1.0 mg/L concentration of BA was more effective in promoting shoot and root growth. The treatments showed that the TDZ treatment was not effective for the shoot and root growth, except for the number of shoots and the fresh weight (FW) of the root; therefore, it was unsuitable for this species. In this study, we established a mass production system of A. ovata. Our results showed that direct in vitro regeneration may make a significant contribution to improving the cultivation of the medicinal plant A. ovata.
