We studied the effect of Rhizophagus irregularis on plant performance and volatile terpenes content of the Mexican native medicinal plant Satureja macrostema (Benth.) Briq. (Lamiaceae) in greenhouse conditions. The growth parameters considered in this research and the composition of volatile components were quantified monthly in mycorrhizal and non-mycorrhizal plants. The essential oil was collected from aerial parts and analyzed by gas chromatography-mass spectrometry. Colonization by R. irregularis significantly increased biomass, shoot and root length, and the amount of volatile terpenes. The more concentrated volatile terpenes were limonene, beta-linalool, menthone, pulegone, and verbenol acetate. It is concluded that the use of R. irregularis allows optimal growth of S. macrostema plants in low fertility soils and increased production of the main components of the essential oil.
