Abstract

The aim of this study was to evaluate the effect of planting space in the form of stem tree Tectona grandis. The data were obtained from an experiment with teak, consisting of four planting spacings being: 3×2 m, 4×2 m, 5×2 m and 6×2 m. At 15 years of age were felled and cubed 30 trees per spacing used for adjustment of the degree of polynomial model 5, proposed by Schöepfer (1966). The model was adjusted by spacing resulting in four different equations which were evaluated by statistical analysis and graphical indicators residues. To check for equality between the shape of the bole, model identity test was applied. Regardless of planting spacing, the used model has provided accurate estimates of diameter with bark along the bole in the four spacings. The results of the model identity test indicated that the shaft profile of the trees spacings 3×2 m and 4×2 m can be expressed by the same equation taper. It also concludes that smaller spacings showed more cylindrical trees over larger spacings.
