The objective of this work was to evaluate the biometric components of plants of the Poaceae family used in the phytoremediation of a soil with the presence of potentially toxic metals. The experiment was carried out in a greenhouse at Escola de Agronomia, Universidade Federal de Goiás, Goiânia – GO, with a sandy textured red-yellow Latosol from an area with a serpentinite rock outcrop, containing high levels of Cr and Ni. The experimental design was in randomized blocks, with 5 treatments and 4 replications. The treatments were composed of: sugarcane, energy cane, elephant grass, capiaçu grass and spontaneous flora. The plants were cut at 250 days after planting and height, stem diameter, number of tillers, green mass and dry mass were analyzed. Sugarcane had the largest stem diameter and high dry biomass, followed by energy cane. Spontaneous flora resulted in lower green biomass. Plants of the Poaceae family perform well in soil with high levels of potentially toxic metals.
