Histo-morphological characteristics in organ differentiation from embryo culture of ginseng(Panax ginseng C. A. Meyer)

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.
