植物生长素能促进发根中次生代谢产物的生成。人参与西洋参的杂交种比亲本有更强的人参皂苷生产能力,但是用种子繁殖该杂交种几乎是不可能的。因此有人利用其愈伤组织、不定根和发根生产高含量的人参皂苷。作者研究了植物生长素对该人参杂交种发根生长及人参皂苷合成的影响。 Auxin promotes the formation of secondary metabolites in hairy roots. Hybrids that participate in American ginseng have stronger ability to produce ginsenosides than their parents, but breeding this hybrid with seeds is almost impossible. Therefore, some people use its callus, adventitious roots and hair roots to produce high levels of ginsenosides. The authors studied the effects of auxin on hair root growth and ginsenoside synthesis in this ginseng hybrid.
