Abstract
Ethephon at 50 microM enhanced both root growth and ginsenoside accumulation in ginseng (Panax ginseng C.A. Meyer) adventitious root cultures, but at 100 microM it inhibited only ginsenoside accumulation. Ginsenoside productivity with 50 microM ethephon was the highest at 1.7 mg l(-1) d(-1) after 8 days of elicitation. However, elicitation with 50 microM ethephon and 100 microM methyl jasmonate (MJ) improved productivity (6.3 mg l(-1) d(-1)) whereas elicitation with 100 microM MJ alone gave only 2.9 mg l(-1) d(-1).
