In the present study a dendrocronological approach developed by the American archae logist Andrew Douglas in 1920 was used to analyze the species Tabebuia impetiginosa and to evaluate the growth tendencies in diameter, commercial volume, percentual annual current increment in commercial volume as well as the commercial form factor. Backman´s function was adjusted to diameter and commercial volume considering the age, obtaining for both an excellent adjustment. Backman´s function was also adjusted for commercial volume, commercial form factor and the percentual annual current increment due to the diameter, obtaining a comparable excellent adjustment. The percentual annual current increment in commercial volume varied from 54,02 % with 7 years to 11,26 % at the age of 21 years. Commercial form factor was 0,7 between diameters of 5,2 and 30,0 cm at the ages of 7 and 21 years, respectively.
