Each fungus inoculated alone stimulated plant growth height and shoot biomass . The response to the dual inoculation was greater than the response to either inoculant one. It may be due to the fact that the co-inoculated plants formed nodules through contaminations. However these nodules are inefficient as the N concentrations were similar in leaves of all inoculated plants with mycorrhizal fungi alone and together. In thus P Ca K Mg and Na concentrations were not improved with respect to dual inoculation. The ectomycorrhizal colonization was significantly higher in the dually inoculated treatment than in either of the singly inoculated treatments. acacia arbuscular mycorrhizas ectomycorrhizas dual inoculation Résumé - Influence de la double symbiose endomycorhiziennne et ectomycorhiziennne sur la croissance de Acacia holosericea A. Cunn. ex G. Don. en conditions de serre. Des plants de Acacia holosericea ont été inoculés soit avec une souche de Glomus aggre-gatum IR27 champignon mycorhizien à arbuscules soit avec Pisolithus .
