This study was conducted to determine the effect of growth regulators, IBA, GA, and BA, on the adventitious bud formation, shoot differentiation, and inflorescence development in embryo culture of Korean ginseng. The adventitious bud formation and shoot differentiation were significantly promoted by application of a combination of 1 ma/l IBA and 5 mg/l GA. The adventitious buds had the primordial shoots and were differentiated as to plantlets. About 5 to 10 adventitious buds developed around the basal axis of the epicotyle of the ginseng embryo, and development of inflorescence was possible only after shoot differentiation. The MS medium supplemented with a combination of 3 mal 1 each of IBA, GA, and BA was most effective for in vitro inflorescence development, and the ratio of inflorescence formation was 18.4%.
