We investigated the effects on ginseng adventitious root growth and ginsenoside production when macro-element concentrations and nitrogen source were manipulated in the culture media. Biomass growth was greatest in the medium supplemented with 0.5-strength NH4PO3, whereas ginsenoside accumulation was highest (9.90 mg g-1 DW) in the absence of NH4PO3. At levels of 1.0-strength KNO3, root growth was maximum, but a 2.0 strength of KNO3 led to the greatest ginsenoside content (9.85 mg g-l). High… CONTINUE READING
