Abstract

This research aims to compare stem volumes of P. oocarpa obtained by the methods of Smalian, form factor, volume equation and taper function. The used data came from 1100 trees distributed in 11 management regimes,  belonging to Duraflora S. A. , Agudos - SP. The trees were cubed and calculated theirs volumes, outside and inside  bark, for the mentioned methods. It was used the Test of  Bartlett and variance analysis for the comparison of  means. The variance analysis showed that significant  difference doesn´t exist among the methods for the 11  management regimes outside and inside bark at the level  of 95 % of probability.
