This study was carried out to obtain the basic information for the shortening of emergence period of ginseng by treatment of growth regulators. Seedlings that removed and non-removed bud sac were treated at 10, 50 and 100ppm of GA$_3$, Kinetin and 2,4-D in early December, and investigated the characteristics of new bud emergence and growth vigor in 2-year-old ginseng. GA treatment showed the most desirable effects in shortening of emergence period of new bud, and elevating its emergence rate with increasing of the GA concentration. In addition, GA treatment especially accelerated the growth of stem and petiole length and early finished the growth of aerial parts of ginseng. On the other hand, root weights were mainly increased by formation of a lot fine roots in GA 50, 100ppm plots.
