Equa??es para estimar a quantidade de carbono na parte aérea de árvores de eucalipto em Vi?osa, Minas Gerais

摘要

The objective of this work was to adjust equations that allow for an accurate estimation of the amount of carbon present in the aerial part of eucalypt trees in Vi?osa, Minas Gerais, Brazil. After the analyses, it was verified that: a) the stem in the aerial part component of the trees with the largest amount of stored carbon, followed by the branches, bark and leaves; b) there is a positive exponential relationship among the amounts of the carbon present in the different parts of the trees (Yi) and the stem dimensions of the trees, expressed by diameter at breast height (dbh) and total height (Ht), that can be described by the following allometric relationship: Yi = a.dapb.Htc ; and c) the variable d.b.h. was significant, at the aerial parts of 95% probability, in the equations estimating the amount of carbon of all the components of the trees, the variable height was significant only for the stem and branch equations.
