The effect of Scleroderma verrucosum (Vaill) Pers and Rhizopogon luteolus Fr. & Nordh. was evaluated on the morphological and biological quality of Pinus radiata D. Don plants in a nursery in Vilcashuaman, Ayacucho, Peru. Treatments: (1) Mycorrhization with Scleroderma verrucosum, (2) Mycorrhization with Rhizopogon luteolus, (3) Mixture of both fungi, and (4) Control, in a completely randomized design with 10 repetitions per treatment. The fungi came from local Pinus radiata and Eucalyptus globulus forests. The inoculation was carried out in the peal at 30 days of sowing and the evaluation at 7.5 months after the peal. The mycorrhizal pines outperformed the control with significant differences in all the variables evaluated. In the stem neck diameter and dry matter of the aerial part, the inoculated treatments did not present significant differences; however, in the height, dry matte...
