Abstract

This study aimed to evaluate the diversity of ectomycorrhizal fungi associated with Pinus patula forest plantations at three altitudinal levels in the province of Chachapoyas, Amazonas. A basic, quantitative, descriptive, and correlational methodology was employed, with a non-experimental design. For fungal collection, a stratified non-probability sampling method was used across a 9 ha, employing 1000 m linear transects and a zigzag method for soil sampling at a depth of 30 cm. Fungal diversity was calculated using the Shannon index, and physicochemical analyses of the soil were performed in the laboratory. The results showed that the physicochemical characteristics of the soil did not differ significantly among the three altitudinal levels studied, maintaining slightly acidic pH values, low electrical conductivity, and adequate nutrient levels. Four ectomycorrhizal fungal species belonging to the Basidiomycota group were morphologically identified: Lycoperdon perlatum, Coltricia perennis, Laccaria laccata, and Suillus luteus. Although fungal diversity varied among the different sectors, no statistically significant differences were found. In conclusion, the diversity of ectomycorrhizal fungi associated with P. patula is not significantly influenced by altitude or soil physicochemical characteristics, but rather depends primarily on local microenvironmental factors specific to each sector.
