- Abstract : Abuscular mycorrhizal fungi (AMF) may establish symbiotic associations with the roots of many plant species. The mycorrhizal symbiosis confer benefits to the hosts plant by improving the uptake of water and nutrients, which may consequently enhance their growth and development. In the present work, the effect of different AMF inoculums (Gigaspora margarita, Glomus deserticola,or a 1:1 mixture of G. margarita and G.deserticola) on the growth of young olive plants (Olea europaea L. cv. Chetoui) was studied. At the end of the experimental period (one year), the potted mycorrhizal olive plants showed a significant increase in the shoot elongation, the number of newly-produced leaves and the leaf area, as compared to the control ones. In addition, an enhancement in fresh and dry biomass was observed in inoculated young olive plants. This beneficial effect of mycorrhizal symbiosis was attributed to the better acquisition of water and nutrients in mycorrhizal olive plants, particularly in plants inoculated by the mixture of G. margarita and G. deserticola.
