Abstract

The objective of this research was to study the relationship between the DBH with crown diameter,stump diameter and inside bark diameter at breast height of Araucaria angustifólia (Bert.) O, Kuntze. The data from the mentioned variables came from 162 Araucaria distributed in the whole amplitude of diameter at breast height in a Mixed Ombrophylous Forest fragment with 15,24 hectares located at the Curitiba urban region, State of Parana, Brazil. All the fitted relationships resulted in predictive equations with good values for the Schlaegel Index, Syx%, value of F and value of Ï for the coefficients, as well as good performance in the graphic analysis of residual.
