Abstract：
:The reported work was designed to increase knowledge about the role of arbuscular mycorrhizal fungi (AMF) on the phytoavailability and allocation of some of the principal macroelements and microelements in young potted olive plants growing in a soil presenting high levels of manganese (Mn), taken from an experimental olive field. A greenhouse trial was performed using self-rooted cuttings of Ascolana tenera, Nocellara del Belice and Carolea cultivars inoculated or not with two mycorrhizal inocula (commercial vs native). Molecular characterization of the indigenous AMF indicated that the species found in the experimental soil were different from those present in the commercial inoculum. The important incidence of AMF on P uptake was confirmed with generally double the concentration in mycorrhizal olive plants as compared to non-mycorrhizal controls, irrespective of genotype and inocula. Furthermore, apart from promoting plant growth (from 1.7- to 5-fold), the symbiosis reduced Mn concentrations from 43 to 83%. The observed differences depended on the cultivar and the inoculum, with native AMF being more effective probably as a result of their adaptation to the experimental soil. No clear direct relationship was found between AMF inoculation and other elements analysed.
