Background : Most ginseng seedlings are cultivated in conventional shading facility. However, due to recent climate changes and soil-related bacterial issues, the production of healthy ginseng seedling with its rhizome weigh more than 0.8g has greatly dwindled. Hence, growing seedling system that raises ginseng on nursery soil in greenhouse is being more highlighted. Nevertheless, there are no sufficient researches conducted to study the growth stability after transplantation of ginseng seedling grown at nursery (GSGN). Methods and Results : After categorizing GSGN produced in 2014 according to individual weight (0.5-0.6g, 0.6-0.7g, 0.7-0.8g, 0.8-0.9g), those GSGN with 0.8-0.9g conventional ginseng seedling (CGS) have been transplanted on preparation field in 17, March of the following year. It has turned out that there were no significant differences about seedling emergence rate and weights between GSGN and CGS both same seedling weight of 0.8-0.9g in 25, June after 100 days transplantation. The 2-year-old ginseng growth of transplanted GSGN according to weight has shown strongly positive correlation between the weight of ginseng seedling and their growth. Especially the leaf area and weight have shown significant correlations represented as Y=212.15-567.32X+499.5X2(R2=0.9988) and Y=4.9-12.9X+11.17X2(R2=0.9788), respectively. Meanwhile, there was no significant correlation noticed treatment plot in relationship between seedling emergence rate and chlorophyll content. Conclusion : With the same root weight of GSGN and CGS, it can be judged that the growth of the 2-year-old GSGN is stable.
