Conteúdo: | The system of taper equations presented in this paper produces reasonably good results for estimation of volumes and diameters of gmelina trees. However, it is clear that this system of equations was not designed for this species as evidenced by the large number of (b3, b4) pairs which had to be relocated. These equations provide much better estimation of diameters and volumes than any taper system previously tried. Demaerschalk and kozak (4) looked at graphs of many equations in order determine which equations best fit their data. They settled upon the top and bottom equations used in this paper. To find equations better suited for estimation in Gmelina trees, diffeent top and bottom equations could possibly be found which would more adequately describe Gmelina profiles. Also in the search for new top and bottom equations, one should keep in mind that integrale functions save computing time and money. It would be advantageous to have both top and bottom diameter euations whose integrations are expressable in closed form. Much work remains in the area of (b3, b4) projection. Only two techniques were considered in this study and one set of boundary values examined. little work has been done in the analysis of (b1, b2) pairs. More than one (b1, b2) pair could be found for a data set. For example, the data could be stratified with respect to DBH classes, HT classes, site classes, etc. Regressions to find b1 and b2 would be run on each class within the data set.
