AbstractBackground: Actually, the technology for the production of mycorrhizal inocula has given a notable boost. However, is necessary to improve the quality of the inoculants by selecting efficient mycorrhizal species that benefit the crops.
Objectives: Identify the diversity of Arbuscular mycorrhizal fungi (AMF) of two soils of San Luis Potosí and its response in the growth of S. vulgare y Zea. mays plants.
Methods: Two types of soils (wet and semi-arid), and sorghum and corn trap plants were used. Growth, mycorrhizal behavior and the CO2 flux of the substrate were evaluated.Results and conclusions: Eleven mycorrhizal fungal species belonging to three families of the Phyllum Glomeromycota were identified. The Glomeraceae family was the most abundant followed by the Acaulosporaceae and the Claroideo-Glomeraceae. The crops increased their aerial biomass in the semi-arid substrate and the root biomass in the wet substrate. The highest CO2 flow rate was found in the semi-arid substrate. The number of spores was greatest in the semi-arid substrate and the percentage and intensity of colonization was greatest in the maize of the semi-arid substrate. The greatest diversity of AMF was replicated in the sorghum trap culture
