Variação estrutural quantitativa no lenho de terminalia ivorensis a. Chev., Combretaceae

Abstract

In order to verify anatomical stem variation of the Terminalia ivorensis wood, were studied wood samples at three different heights in the radial and axial planes. Proof bodies were gotten at a 2cm interval from the pith towards the vascular cambium. The utilized methodology to develop the job followed the traditionally recommended methodology for vegetable anatomy studies. The anatomical description followed the recommendations of the IAWA Committee. In the radial stem direction, some anatomic elements showed a well defined trend, which are statistically significant when using the Tukey test for measures comparison. They were: frequency, diameter and length of the vessel elements, ray frequency/linear mm, length of rays in number of the cells and fiber length and thickness. On the other side, in the axial stem direction, was not found anything statistically significant. This results were observed principally due the clear presence of the juvenile and adult wood in the lumber of Terminalia ivorensis.
