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.
