Abstract Five different species of arbuscular mycorrhizal fungi (AMF), three of which were isolated from hydrocarbon polluted soils ( Glomus deserticola , G. geosporum and G. intraradice s) and two labora‐tory 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 gas‐oil polluted soil from Mar de Ajó, G. geosporum isolated from fuel‐oil polluted soil from Berisso, G. intraradice s isolated from crude‐oil polluted soil from Ensenada (Argentina), and Glomus fasciculatu m (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.
