Abstract

This study aimed to determine the artificial form factor and confection table form factor for teak in Brasnorte and Santo Antônio do Leverger, Mato Grosso State, Brazil. A hundred tress were measured and 162 were cubated in stands from 20 to 10 years of age. The volume was estimated using Smalian and form factors by the reason between the estimated and cylindrical volumes. Sixteen models of artificial the form factor werw tested, and the equation ln(f1,3)=0,774+0,697.ln(d0,5/d²)-0,647.ln(d0,1/d²)+0,199.ln(1/h.d) presented the best fit with the diameter of Hohenadl (d0.5 e d0.1) estimated by the respective equations: ln(d0,5)= -1,066.ln(1/d)+0,234.ln(1/h) and ln(d0,1)= 0,753 - 0,535.ln(h/d²)+0,199.ln(h). The form factor table covered a amplitude from 0.4038 to 0.6443.
