Geoestatística na avaliação da variabilidade espacial e temporal das características dendrométricas do Genipa americana L.

Abstract

To promote an optimization of the use of forest resources are fundamental knowledge, quantify and monitor them. Thus, the objective of this work was to evaluate a spatial and temporal variability of the dendrometric characteristics of Genipa americana L. The experiment was installed in the experimental area of the Federal University of the Recôncavo da Bahia, in Cruz das Almas, being evaluated until the eighth year of age. The experimental design was a randomized block design with five spacings and four replications. For the georeferencing of the trees and used in the global positioning system of the geodetic type. The models were based on the best semivariogram adjustments and an interpolation was performed by the ordinary kriging method. It was confirmed the existence of moderate spatial dependence for all years and variables. The temporal variability evidenced the differentiation of the divisions of the diameter and height classes over the years, estimating the increase of the development of the jenipapeiro as a function of age. The treatment that presents better development for the height and the diameter of the space 3.0 x 3.5 m, evidencing that the greater area per plant provided greater height and diameter at 8 years of age.
