This study describes the mycorrhizal status of Populus alba, the main species of the riparian reserve of Sidi Boughaba (northwest of Morocco) and accompanying species: Smyrnium olusatrum, Urtica membranacea, Ononis natrix, Pteridium aquilinum. Microscopic examinations of these species roots have revealed the presence of endomycorrhizal and endophytic structures in all samples. Mycorrhizal frequency and intensity have respectively reached 100% and 75%. The spore’s number of the endomycorrhizal species those were isolated from the rhizosphere of these plant species reached 78 spores/100g of soil. Spores belonging to the genera of Glomus, Acaulospora, Scutellospora, Gigaspora and Kuklospora. Scutellospora nigra and Scutellospora sp1 are the two most abundant in the sites of the Sidi Boughaba riparian.
