摘　　要：植物激素在调控植物生长发育、环境适应及次生代谢中发挥着重要作用,尤其是在药用植物中的科学合理利用对促进其有效成分的形成具有良好效果。人参具有重要的药用价值,其有效成分人参皂苷的形成受各种环境因子的影响,而植物激素作为植物对环境条件适应的调节剂,在调控人参皂苷生物合成中发挥重要作用。文章归纳分析了茉莉酸、水杨酸、生长素、脱落酸和赤霉素在人参皂苷生物合成中的作用及调控机制,指出植物激素作为信号分子介导人参皂苷生物合成途径中的关键酶活性或基因差异表达,从而影响人参皂苷的合成,并初步绘制了茉莉酸、水杨酸、生长素、脱落酸和赤霉素调控人参皂苷积累示意图,同时展望未来植物激素在药用植物中应用的研究方向,为在生产实践中推进中药材“高产优质”种植提供参考和借鉴。Plant hormones play an important role in the regulation of plant growing development,environmental adaptation and secondary metabolism.Especially,the scientific and rational utilization in medicinal plants has a good effect on promoting the formation of their effective components.Panax ginseng is known as the"king of herbs"and has important medicinal value.The formation of its functional component ginsenoside is affected by various environmental factors.Plant hormones are regulators of plant adaptation to environmental conditions and play a key role in regulating ginsenoside biosynthesis.Based on the application of plant hormones in Panax ginseng,this paper summarized and analyzed the role and regulatory mechanism of jasmonic acid,salicylic acid,auxin,abscisic acid and gibberellin in ginsenoside biosynthesis. It pointed out that plant hormone act as signaling molecules to mediate key enzyme activities or gene differential expression in ginsenoside biosynthesis pathway,thus affecting the synthesis of ginsenosides. The diagrams of jasmonic acid, salicylic acid, auxin, abscisic acid and gibberellin regulating the accumulation of ginsenosides were preliminarily drawn, and future research direction of the application of plant hormones in medicinal plants was predicted. The purpose of this paper is to provide reference for promoting the “high-yield and high-quality” cultivation of traditional Chinese medicine in production practice.
