- Abstract
It was aimed to fit volumetric models and classify the volumetric potential of Lecythis lurida (Miers) Mori in Tapajós National Forest. The data come from two Annual Production Units (UPAs) of the forest management area of Mixed Cooperative of FLONA Tapajós (COOMFLONA). Volumetric models were fitted and the best one was chosen based on R²aj., Syx%, significance of the parameters and graphical analysis of residues. For the classification volumetric potential, the simple Euclidean distance was used as a measure of dissimilarity and the Ward method as clustering algorithm. The discriminant analysis was applied to verify veracity of the distinction and classification of Work Units (UTs) in homogeneous classes of volumetric stock. The double-entry models were statistically superior to the single-entry, with the Schumacher-Hall model resulting as the best, with R²aj. of 81.62% and Syx% of 16.91%. The discriminant analysis indicated that the classification of UTs in the volumetric stock classes was 100% correct, in which the multivariate analysis allowed the stratification of the exploitation area in three classes of productive capacity for L. lurida, contributing to the better planning the forest activities involving this species.
