This study was conducted to determine the optimum culture conditions for inducing callus and regenerating plantlets from cultured leaf tissues of Aralia elata. Young leaf tissues(1cm) of A. elata plant were cultured on MS medium supplemented with 2, 4-D and Thidiazuron. Embryogenic callus was induced along the leaf veins, more efficiently on the medium containing 1.0mg /1 Thidiazuron in 4 weeks after culture initiation. Calli were subcultured to proliferate on MS media containing 2, 4-D, Dicamba, Picloram, and Thidiazuron. Callus was better proliferated on the medium containing Dicamba than on the others.. However, callus subcultured on the medium containing Thidiazuron was more embryogenic and light green-colored, of which some showed embryoid-like structure on the surface. Hormone-free medium was more efficient to regenerate plantlets than media supplemented with Kinetin, BA, and Thidiazuron.
