The objective of this research was to evaluate the Angico seedling growth [Anadenanthera macrocarpa (Benth.) Brenan] under the effect of arbuscular mycorrhizal fungi inoculation (FMAs) in preserved and antropized soils. This study was developed under greenhouse condition and the experiment was arranged in a complete random design within a factorial scheme 2x4 with five replications. There were two soils (preserved and antropized) and four treatments of mycorrhizal inoculation: (1) sterilized soil and inoculated with association of Glomus etunicatum + Paraglomus brasilianum; (2) sterilized soil and inoculated with association of Glomus etunicatum + Gigaspora margarita soil; (3) sterilized and not inoculated soil, i.e., control; and (4) natural soil (not sterilized and not inoculated). The growth in height was evaluated each 15 days and the leaf area, root and shoot dry matter, root length, shoot nutrient contents and mycorrhizal colonization were evaluated on the 150th day. The best growth of Angico seedlings was observed in the treatment with sterilized soil inoculated with a mixture of Gigaspora margarita and Glomus etunicatum, which caused increases in leaf area, root and shoot dry matter, as well as longer roots and larger mycorrhizal colonization, in both preserved and antropized soils.
