Enhanced Ginsenoside Productivity by Combination of Ethephon and Methyl Jasmoante in Ginseng (Panax ginseng C.A. Meyer) Adventitious Root Cultures

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