Abstract: This study was conducted to regenerate shoots from internode sections(about 1mm in thickness) of Ardicia pusilla de Candolle. Internode sections were cultured on MS medium supplemented with TDZ or both TDZ and IBA. At one month after culture, primodium, which looks like protocorm like body(PLB) of orchid, appeared around swollen internodes. And then it grew and changed into the shape similar to granule of orange at two or three months after culture. At four to five months after culture, explants covered with them became a cluster, and then multiple shoots were regenerated from them. Primodia formation was the best when internode was cultured on MS medium supplemented with 0.25 $mg{\cdot}L^{-1}$ thidiazuron(TDZ) and 0.5 $mg{\cdot}L^{-1}$ indole-3-butyric acid(IBA). That internodes were cultured on MS medium supplemented with either higher concentration of TDZ than that of IBA, or equal concentration of TDZ and IBA, or TDZ only was little effective for primodia formation.
