Resumo: | Seven mathematical models were evaluated in their prediction ability to estimate merchantablestem volume and dry weight, both inside and outside bark, for 6 and 11-years-old Pinus taeda trees, planted in Telêmaco Borba, State of Paraná. On the basis of criteria used for comparative analysis, the combined variable model (Y = b0 + b1 d2h) was judged to be the most suitable, due to accuracy and precision of the estimates of individual tree volumes and dry weights for 6-year-old plantations and for grouping of all trees studied . For 11- year-old plantations, the best model to estimate volume and dry weight used the independent variable d2 (Y = b0 + b1 d2), selected due to simplicity and good prediction ability. |
