ABSTRACT
The presence of arbuscular mycorrhizal fungi (AMF) in the rhizosphere of Ceratonia siliqua was studied
in five provinces in Morocco: Taroudant, Khenifra Azilal, Nador and Beni Mellal. These regions contain
large populations of carob. The microscopic examination of the carob tree roots has revealed the
presence of the arbuscular endomycorrhizae in the all samples. The mycorrhizal frequency is greater
than 90% in all study sites and the highest mycorrhizal intensity was observed in Zaio site (21%).
Spores’s number of MAF isolated from different soils is between 84 and 160 spores/100g of soil. These
spores present 30 AMF species belonging to six genera: Glomus (15 species), Acaulospora (7 species),
Scutellospora (4 species), Gigaspora (2 species), Entrophospora (1 species) and Pacispora (1 species).
The species, Glomus etunicatum, is the most abundant, its frequency of occurrence is about 12% of all
AMF isolated.
Keywords: Morocco, Carob (Ceratonia siliqua), Arbuscular Mycorrhizal Fungi, diversity.
