Abstract:Arbuscular mycorrhizal fungi have mutualistic symbiosis with higher plants, increasing plant resistance to environmental stresses and nutrient uptake and improving soil. During arbuscular mycorrhizal symbiosis, a range of chemical and biological factors are affected. In this study, two species of arbuscular mycorrhiza (Glomus mosseae and G. intraradices) were used to assess the effects of inoculation on licorice growth and secondary metabolite production. After successful inoculation, the increase in the growth rate, P and Zn uptake, and the accumulation of secondary metabolites in licorice (Glycyrrhiza glabra L.) roots were observed in two periods of 3 and 6 months compared to control. After 6 months, more increments in growth, secondary metabolites, and P and Zn uptake were observed compared with the first 3-months period. Two groups of secondary metabolites arising from phenolic and terpenoid metabolism obviously responded to mycorrhizal fungi colonization in licorice roots.
