✦ Synopsis

Five different species of arbuscular mycorrhizal fungi (AMF), three of which were isolated from hydrocarbon polluted soils (Glomus deserticola, G. geosporum and G. intraradices) and two laboratory strains (G. fasciculatum and G. mosseae), were screened for symbiotic response with Medicago sativa L. (alfalfa) under greenhouse conditions in a hydrocarbon polluted substrate. Four of the 5 treatments were found to improve plant height and shoot biomass: G. deserticola isolated from gasoil polluted soil from Mar de Ajó, G. geosporum isolated from fuel-oil polluted soil from Berisso, G. intraradices isolated from crude-oil polluted soil from Ensenada (Argentina), and Glomus fasciculatum (laboratory culture). A significant increase of phosporous and zinc content was only found in shoots and roots after treatment with AMF isolated from polluted areas.
