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).
50微摩尔的乙烯利可促进人参(Panax ginseng C.A. Meyer)不定根培养物中的根系生长和人参皂苷积累,但100微摩尔时仅抑制人参皂苷积累。诱导8天后,50微摩尔乙烯利处理的人参皂苷产量最高,为1.7毫克/升·天。然而,50微摩尔乙烯利与100微摩尔茉莉酸甲酯(MJ)共同诱导可提高产量(6.3毫克/升·天),而单独用100微摩尔MJ诱导时产量仅为2.9毫克/升·天。
