| Abstract: | Adventitious roots of ginseng were treated with methyl jasmonate (MJ) up to 150 m and cultured for 40days. Up to 100m MJ inhibited the root growth but increase ginsenoside accumulation. In a two-stage bioreactor culture, total ginsenosides, after elicitation with 100 m MJ peaked after 10days at 48mgg–1 dry wt and then dropped sharply. Of the two groups of ginsenosides (Rb and Rg), higher amounts of Rb accumulated in the adventitious roots.Revisions requested; 2 July 2004; Revisions received 30 June 2004; 3 September 2004 |
