Resumo: | This study aimed to test the hypothesis that crown length affects the hypsometric relationship. We used data from diameter measured at 1.3 m above ground level (DBH) and total heights of 337 trees of Araucaria angustifolia (Bertol.) O. Kuntze from an urban remnant of Araucaria Forest with 15.24 ha, located in Curitiba, PR, Brazil. These trees were grouped into classes of crown length. Six hypsometric models were adjusted to the data for each class and for the entire data set. The best model was chosen based on the standard error of estimate in percentage, index of Schlaegel, and graphical analysis of residuals. The ranking indicated Trorey as the best model. The models identity test of Graybill applied to the Trorey model indicated that crown length influenced the hypsometric relationship of the araucarias in the study area.
