CHARACTERIZATION OF ARBUSCULAR MYCORRHIZAL FUNGI ASSOCIATED TO THREE PROVENANCES OF PIGEON PEA (CAJANUS CAJAN L.)MILLSP. GROWN IN THREE SOILS FROM TWO DIFFERENT REGIONS IN SENEGAL

Pigeon pea (Cajanus cajan L.)Millsp., often referred to as the meat of poor people, is a valuable underutilized agricultural resource in Africa, particularly in Senegal. This legume offers a diverse range of food and environmental benefits, making it a key element for food security and sustainability of agricultural systems, especially in tropical and subtropical regions.The aim of this study was to evaluate the density and diversity of arbuscular mycorrhizal fungi (AMF) associated to three provenances of pigeon pea cultivated in three soils from two regions in Senegal.My corrhizal parameters were determined in the three soil origins; and added to growth parameters after trapping culture with three pigeon pea provenances in these soils for 4 months. The results revealed significant differences among the soil origins and the presence or absence of theplant for AMF density and diversity, and mycorrhizal potential. Seven morphotypes of AMF belonging to five genera (Racocetra, Scutellospora, Dendiscutata, Gigaspora and Glomus) were identified. Spore density was higher in Kaolack and lower in Kaffrine.
