ABSTRACT

Twenty-one and twenty eight mycorrhizal species were isolated respectively from the rhizosphere of maize and sorghum three months after inoculation with a composite inoculum originating from the rhizosphere of the carob tree (Ceratonia siliqua). Similarly, twenty six species were found in the rhizosphere of the carob tree plants ten months after their inoculation with the same inoculum. Analysis of endomycorrhizal fungi spore’s communities found in the rhizosphere of these mycotrophic species has shown the dominance of five species: Acaulospora pustulata (9,67%), Glomus etunicatum (9,67%), G. clarum (9,67%), G. deserticola (24,5%) et Scutelospora nigra (16%). Furthermore, a comparison between AM fungi species of the initial inoculum (30 species) and those isolated has revealed the appearance of twenty six species and the disappearance of eleven others.
