Study of the Diversity of Arbuscular Mycorrhizal Fungi in the Highway Slopes of Taza Region (North-East of Morocco)

The diversity of arbuscular mycorrhizal fungi (AMF) was examined in the cut and filled slopes of Taza region (North-East of Morocco). The identification of the spores isolated from these two types of slopes has revealed 29 species belonging to 7 genera: Glomus (14 species), Acaulospora (6 species), Gigaspora (2 species), Pacispora (3 species), Entrophospora (2 species), Scutellospora (1 species), Funelliformis (1 species), 6 families (Glomeraceae, Gigasporaceae, Acaulosporaceae, Pacisporaceae, Scutellosporaceae, Entrophosporaceae) and 3 orders (Glomerales, Gigasporales, Diversisporales). The number of specific species to cut and filled slopes is respectively 12 and 6 species and the number of species common to the two types of slopes is 11 species. All these species will serve, after multiplication, as sources of endomycorrhizal inoculum, which can enhance the growth and increase the resistance of plants, used for vegetation and restoration of the slopes.
