In this sense, this study aimed to evaluate the ectomycorrhizal association of Tuber aestivum Vittad. and Tuber brumale Vittad. in pecan after five years of cultivation in an orchard. The experiment was conducted in Santa Maria – Rio Grande do Sul, Brazil, in a pecan orchard planted with seedlings inoculated with these two species of truffles. The orchard was characterized in terms of soil physical and chemical properties and soil type. Initially non-inoculated plants, plants inoculated with Tuber aestivum (TA), and plants inoculated with Tuber brumale (TB) were evaluated for the percentage (%) of roots colonized by Tuber spp., other ectomycorrhizae, and non-mycorrhizal roots. A reduction in the colonization of both truffle species was observed five years after transplanting the seedlings to the orchard but they have the potential to maintain the ectomycorrhizal association with pecan seedlings.
