Growth and macro and micronutrient contents of Pinus greggii Engelm. inoculated with the edible ectomycorrhizal mushroom Hebeloma mesophaeum (Pers.) Quél. was evaluated. The experiment consisted of two treatments: plants inoculated with H. mesophaeum and non-inoculated plants. Results showed that shoot and root dry weight, shoot height, stem diameter, and total contents of N, P, K, Ca and Mg were higher in inoculated plants than in non-inoculated plants. P and Mg contents were 6.7 and 6.9 times respectively higher in the shoot of inoculated plants in comparison to non-inoculated plants. Additionally, H. mesophaeum originated a high translocation efficiency of P, K and Mg to the shoot. The percentage of mycorrhization was high (79.5 %); more than half of it being observed in the central part of the root ball in the plant containers. Therefore, inoculation with H. mesophaeum has a great potential to be used in the production of P. greggii plants under greenhouse conditions.
