| 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 NH$_4$PO$_3$, whereas ginsenoside accumulation was highest (9.90 mg g$^{-1}$ DW) in the absence of NH$_4$PO$_3$. At levels of 1.0-strength KNO$_3$, root growth was maximum, but a 2.0 strength of KNO$_3$ led to the greatest ginsenoside content (9.85 mg g$^{-1}$ ). High concentrations of MgSO$_4$were most favorable for both root growth and ginsenoside accumulation (up to 8.89 mg g$^{-1}$ DW). Root growth and ginsenoside content also increased in proportion to the concentration of CaC1$_2$ in the medium, with the greatest accumulation of ginsenoside (8.91 mg g$^{-1}$ DW) occurring at a 2.0 strength. The NH$_{4}$$^{+}$/NO$_{3}$$^{[-10]}$ ratio also influenced adventitious root growth and ginsenoside production; both parameters were greater when the NO$_{3}$$^{[-10]}$ concentration was higher than that of NH$_{4}$$^{+}$. Maximum root growth was achieved at an NH$_{4}$$^{+}$/NO$_{3}$$^{[-10]}$ ratio of 7.19/18.50, while ginsenoside production was greatest (83.37 mg L$^{-1}$ ) when NO$_{3}$$^{[-10]}$ was used as the sole N source.ource. |
