Abstract

This work focuses on the arameters estimation of generalized gamma distribution to describe the diameters distribution of a no thinning equiano eucalyptus stand and evaluate the biological reality of a equations system to design such parameters and describe this distribution in a future age. Were used 48 plots with four measurements per year, from an experiment installed in a Eucalyptus grandis x Eucalyptus urophylla hybrid stand, located in the northeastern of Bahia state. The equations system to projection for the parameters was assessed using the correlation coefficients between the estimated and observed variables and the errors graph for each equation of model. The generalized gamma distribution presented satisfactory adjustments to the data. The equations system to describe the parameters tendency of this function also showed good adjustment. It was concluded that the generalized gamma function generates consistent and accurate estimates and can be used for modeling the diameter distribution in eucalyptus stands.
