Abstract
We established that regenerated plants of Panax ginseng were directly transplanted into the soil without the acclimatization process. When regenerated plants were treated at the concentration of $0.4mg\;l^{-1}$ for 9 hr before transplantation into the soil, our results showed that the survival rate of them was the highest. The optimal size of the root was above 4 cm in length and 0.4 g by weight before transplantation into the soil. The highest survival rate increased to 59.6%. After 4 years of cultivation in the fields, our results showed that there were no significant morphological differences between regenerated plants and wild-type ginseng. Also, we obtained healthy seeds from regenerated plants. This study provides the basis for a relatively rapid multiplication of selected genotypes and will allow a much more rapid evaluation of the germplasm of the unexplored and unstudied Korean ginseng.
