Popis: | One-year-old Glycyrrhiza uralensis Fisch. ex DC, Fabaceae, was treated with three exogenous phytohormones in June and July, namely gibberellin, auxin (indole-3-acetic acid), methyl jasmonate at different concentrations. Control plants were treated with water. Roots of controls and hormones-treated G. uralensis plants were harvested at different times, and the contents of seven main chemical components were determined. Root glycyrrhizic acid content of plants treated in June increased significantly compared with controls, and the difference was significant. As for plants treated in July, root glycyrrhizic acid content increased in which sprayed with appropriate concentrations of hormones, but the effects of hormones were more evident in plants treated in June coincided with the vigorous growth period than those treated in July. Gibberellin at 40 mg/l and auxin at 40 mg/l applied in the two treatment periods significantly promoted the accumulation of glycyrrhizic acid in G. uralensis root. Treatment with methyl jasmonate at 100 and 25 mg/l in June and July, respectively, also increased glycyrrhizic acid content significantly. The determination of major active compositions indicated that liquiritin, isoliquiritin, isoliquiritin apioside and liquiritin apioside contents were positively related to glycyrrhizic acid content. The study preliminarily found phytohormones and the main chemical components associated with glycyrrhizic acid content, and these discoveries could provide a basis for establishing a chemical control network with glycyrrhizic acid as the core, confirming the secondary product metabolic pathways in the network and completely uncovering synthesis mechanism underlying glycyrrhizic acid-combined functional gene polymorphism.
