dc.descriptionThe present work carried out with native, adult and young trees of the species Ceiba pentrandra (sumauma), cultivated in flood plains (varzea) and in upland (terra firme) ecosystems. The objective was to obtain information about growth patterns of the species and to correlate them with different environmental conditions (varzea e terra firme), as well as to investigate anatomical and physical parameters of the wood. The wood quality of adult native trees was compared with the wood quality of young trees cultivated on varzea and terra firme. Investigations were carried out on the radial variations of density and anisotropy, as well as on the wood anatomical structure on the pith-bark direction on the samples of wood taken at breast height (DBH). From the results obtained, it can be concluded that the cultivated trees on the varzea and in terra firme ecosystems, as well as the native trees, presented an increase of density from pith to bark. The sctructural density of the cultivated trees at the terra firme ecosystem was higher, followed by the trees cultivated at the varzea, when compared with native sumauma. The anisotropy contraction index indicates that sumauma is highly dimensionally unstable. Therefore, its range of use in the area of construction is limited.
