These studies were conducted to obtain the propagation method from the embryos of the Korean ginseng cv. violet-stem var. (Panax ginseng C.A. Meyer) There were five types of the shoot formations in the ginseng embryo culture and those are the adventitious bud from the epicotyl, the direct shoot formation from the cotyledon, the shoot primordium initiated from cortex of cotyledon, the adventitious shoot from callus and the somatic embryogenesis. In the case of the shoot formation from the epicotyl, the adventitious buds were initiated from a number of the meristematic tissues at the basal part of epicotyl and consequently developed to multi-shoots. However, in callus tissue, an embryo developed from an individual somatic cell in the callus mass by the somatic embryogenesis. The cotyledon and the roots were developed from epicotyl and hypocotyl of the embryo but the stem and the leaves were not differentiated from the cotyledon developed from somatic embryo.

This study was carried out to find out the optimum hardening condition for ginseng plantlets redifferentiated by tissue culture method. While a lot of root hair were observed on the root of seedling grown on the soil, few root hair were observed on the root of plantlet redifferentiated in vitro. On the medium solidified with 0.1 % phytagel, root hair was not observed and root weight, root width and laternal root development were also very poor. While raising the phytagel concentration on the media, root hair began to increase and root weight, root width and laternal root development were improved. Vascular tissue of plantlet grown on the medium with 0.1 % phytagel was very poor, but that of plantlet grown on the medium with 0.8% phytagel was very good.
