- Abstract
This research aimed to evaluate biometric characteristics and mortality in different clones of Eucalyptus and adjust hypsometric and volumetric models. The experiment was conducted at the experimental farm Prof. Dr. Luis Eduardo de Oliveira Sales, in Brazil, and mounted in a completely randomized design, with three clones Eucalyptos spp. (Ripasa I, Ripasa II and IPBR) and 4 replications. Seedling planting was conducted in August 2007 and biometric evaluations in May 2014 with 18 plants were collected and evaluated the diameters at breast height (DBH), plant height, total wood volume and mortality rate. These data were submitted to variance analysis and comparison of means was performed using the Tukey test at 5% probability. To estimate the height models Trorey, Stoffels and Curtis and to estimate the volume of wood models Kopezky-Gehrardt, Husch and Schumacher- Hall were tested. The comparison of results was by the coefficient of determination (r2), the coefficients "a" and "b" of the linear regression equations, standard error of estimate (ESE), Willmott index of agreement (d), the Pearson correlation coefficient (r), confidence coefficient (c) and performance of Camargo and Sentelhas. The eucalyptus clones didn't differ in DBH, mortality rate and total volume of wood and the Ripasa I showed greater plant height. The hypsometric models haven't estimated satisfactorily and single and double models to estimate the total volume of wood produced good results, however, of Kopezky-Gehrardt and Husch should be preferred in the eucalyptus plantation in Brazil, for its simplicity of use.
