Resumo: ABSTRACT This study aimed to quantify total carbon and its compartments: roots, stems, branches, and aciculas, in order to select an estimated equation of the total organic carbon for Pinus taeda L. settled from natural regeneration in the forest understory of a planted forest in the municipality of Três Barras, SC. Data have been collected from a random selection of 96 individuals with diameter at 0.3 meters above ground level, varying from 2.5 to 19cm. The selected individuals had their dimensional variables (dendrometric and morphometric variables) measured being subsequently felled and their compartments separated, weighed and samples were collected and taken to analysis of carbon contents. Eight traditional models were tested, six arithmetic and two logarithmic, as well as a model developed by the Stepwise process, being total organic carbon the dependent variable, and dimensional variables the independent variables. The total organic carbon found was 46.7% on average, and Tukey-Kramer test indicated significant differences of carbon contents amongst compartments. In comparison with traditional equations tested, the equation adjusted by Stepwise seemed more accurate, with good fit (R2aj. = 0.931) and precision (Syx% = 18.5).
