Equação de volume para espécies de Cerrado em Formosa, GO

This study aimed to develop models for estimating wood volume of individual trees for nine Cerrado species of Formosa, State of Goias, Brazil. Data were collected from 12 to 15 trees of nine species, representing the diametric classes amplitude of each species in the studying area. Trees were logged and measured and the volume was calculated by Smalian method. Seven mathematical models were tested to estimate the wood volume by species and total. The best model was selected through statistical parameters adjusted coefficient of determination, standard error of the estimate and graphical. distribution of residues. Hohenadl-Krenn (simple input) and Naslund modified (double input) presented the best results to estimate individual tree wood volume for nine studied species and also for all nine species together.
