Diversity of Arbuscular Mycorrhizal Fungi Species Associated with Soybean (<i>Glycine max</i> L. Merill) in Benin

Arbuscular Mycorrhizal Fungi (AMFs) could be used to sustainably improve crop yields. The present study evaluated the diversity of AMF species associated with soybean (Glycine max L. Merill) in main soybean-producing areas Benin. Composite soil samples from 13 production at a rate 04 villages per were collected. A spore trapping device was set up reveal spores. physical and chemical properties soils, frequency intensity mycorrhization roots, spores determined following trapping. As result, eight morphotypes belonging four genera: Glomus, Acaulospora Gigaspora Disversispora three families: Diversisporales, Glomérales Paraglomérales observed. An important variability densities observed one another higher abundance Copargo estimated 3584 spores/100g soil. biological indexes as Shannon (0.0311), Simpson (0.0204) Hill (0.0235), varied significantly (p < 0.05) another. There significant correlation between parameters studied, particularly physico-chemical soils indexes. For parameters, mycorhization frequencies did not vary another, unlike intensities, which (2.31% 24.62%). Finally, this revealed that had an influence on other studied. Moreover, there diversification AMFs different areas, are influenced by certain parameters.
