Volumetry of Genipa americana in homogeneous plantation in Southwest Bahia

Abstract

This research aim to evaluate the volumetric estimates obtaining for Genipa americana, commonly known as jenipapeiro, in pure plantation in the municipality of Vitória da Conquista, Bahia State, Brazil. To determine individual volume, 100 standing trees were rigorously cubed. Ten volumetric models were adjusted. The best models were selected based on the selection criteria of weighted value of statistical parameters scores and residues distribution. Volume estimates were obtained by form factor and by adjusted equations. To validate the estimates, the calculate volumes were compared to measured data. Among the used methods to predict wood volume, the adjusted volumetric equations are recommended. Spurr (Log) model present the best performance to estimate total wood volume.
