Abstract
MENA ECHEVARRIA, Aracely; MENDEZ CORTES, Heriberto; RAMIREZ TOBIAS, Hugo M. and ROJAS VELAZQUEZ, Ángel Natanael. Comparison of two soils for the production of mycorrhizal inoculants in San Luis Potosí, México. Sci. fungorum [online]. 2021, vol.51, e1315. Epub Feb 28, 2022. ISSN 2594-1321. https://doi.org/10.33885/sf.2021.51.1315.
Background:
Currently, the technology for the production of mycorrhizal biofertilizers has experienced a notable boost. However, it is necessary to improve the quality of the biofertilizers by selecting efficient mycorrhizal species that benefit the crops.
Objective:
Identify the diversity of arbuscular mycorrhizal fungi (AMF) of two soils of San Luis Potosí and its response in the growth of Sorghum vulgare y Zea mays.
Methods:
Two types of soils (wet and semiarid), and Sorghum vulgare y Zea mays 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 Claroi-deo-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 efficiency of colonization was greatest in the Zea mays of the semi-arid substrate. The greatest diversity of AMF was replicated in the Sorghum vulgare trap culture.
