Popis: This study aimed at estimating the biomass in a 5.5-year-Platanus x acerifolia stand, in Dom Feliciano county, Rio Grande do Sul. The inventory in the experimental area was done in five plots (20 m x 30 m each one). Trees were grouped in eight diameter classes, and 3 trees per class were cut. After cutting the trees, a cubing was done and the biomass of each component (leaf, fruit, branch, bark, wood and root) was determined and sampled. The biomasses estimative from each component were done through regression equations adjustment that correlated dendrometric characteristics with biomass volumes from the respective components of the trees. The total biomass was 45,28 Mg h-1, distributed in: wood 21,07 Mg ha-1; branch 11,72 Mg ha-1; root 8,43 Mg ha-1; bark 2,01 Mg ha-1; leaf 1,89 Mg ha-1 and fruit 0,16 Mg ha-1. The accumulated litter was 12,80 Mg ha-1.
