研究了8个西洋参野生居群人参皂苷含量的遗传和环境效应。在野外采集植物时(T0)和将8个种群的根移植到两个不同的森林公园地点后的2年(T2)，测定了6种人参皂苷的根浓度。地理位置和种群对根系和地上部的生长均有显著影响。总体而言，人参皂苷Rb1含量最高，其次是Rg1和Re。Rg1和Re的浓度在种群间和种群内呈负相关。根据特定的人参皂苷和采样时间不同，种群的相对排名也不同。对于所有的人参皂苷来说，基因和环境的相对重要性并不相同。人参皂苷Re受种群影响而不受地点影响，Rb1、Rc和Rb2仅受地点(环境)影响，Rg1和Rd受两者共同影响。人参皂苷水平一直较低，但在管理较密集的花园位置，人参皂苷水平一直较高。
Genotype and environmental effects on ginsenoside content among eight wild populations of American ginseng (Panax quinquefolium) were investigated. Root concentrations of six ginsenosides were determined at the time of collection of plants from the wild (T0) and 2 years (T2) after transplanting roots from each of the eight populations to each of two different forest garden locations. Both location and population had significant effects on root and shoot growth. Overall, ginsenoside Rb1 was most abundant, followed by Rg1 and Re. Concentrations of Rg1 and Re were inversely related among and within populations. The relative ranking of populations differed depending upon the particular ginsenoside and sampling time. The relative importance of genotype and environment was not the same for all ginsenosides. Ginsenoside Re was influenced by population but not location, whereas Rb1, Rc, and Rb2 were influenced only by location (environment), while Rg1 and Rd were influenced by both. Ginsenoside levels were consistently lower, but growth was consistently higher at the more intensively managed garden location.
