| To obtain multi-shoot using zygotic embryos dissected from ginseng seed, the embryos were cultured on MS medium supplemented with CPA and BA. Effective multi-shoot induction was achieved on 0.5mg/ t CPA and 1.0mg/ t BA treatment. Among the various plant growth regulator treatment, MS basal medium with 1mg/ t 2,4-D and 0.5mg/ t kinetin was more competent and could be induced 4¡6 shoots per one embryo. Also, the best condition for pre-embryoid induction from ginseng cotyledon so as to ginseng transformation appeared to 1mg/ t 2,4-D and 0.5mg/ t kinetin treatment. The kanamycin level to select transformants varied greatly by different explant tyues. The petiole explants with leaf and embryo could survived up to 100$mu extrm{g}$ / ml kanamycin concentration where as petiole explants without leaf died all at the level. Conclusionally, our results suggest that optimum kanamycin concentration for ginseng transformation using somatic embryos is about 75¡100$mu extrm{g}$ / ml concentration. |
