| Summary: | <p>The effect of the inoculation of arbuscular mycorrhizal fungi on the growth of two legume trees (<em>Cassia leiandra</em> and <em>Chamaecrista desvauxii</em>) was evaluated. The experimental design was completely randomized with four treatments and twenty-five repetitions. The treatments were: <em>Glomus clarum</em> (Nicolson & Schenk), <em>Gigaspora margarita</em> (Becker & Hall), Native Fungi and Control (without inoculation). The seedlings were cultivated in a substratum composed of compost, clay, sand and natural phosphate in the proportion of 6:2:1:1. One Hundred and sixty eight days after seed germination, stem diameter, height, above-ground biomass, below-ground biomass of thick and fine roots, and percent mycorrhizal colonization were evaluated. Although the roots of <em>Chamaecrista desvauxii</em> were colonized with <em>Gigaspora margarita</em> there was no effect of the inoculation on any of the variables measured. Seedlings of <em>Cassia leiandra</em> were colonized by all mycorrhizal fungy, however, there was an increase in the above-ground biomass and below-ground biomass of fine roots only on the seedlings inoculated <em>with Glomus clarum</em>.</p> |
