Caracterização anatômica de espécies florestais do Norte de Mato Grosso

Abstract

This work had the general objective of anatomically characterizing the wood of Inga cylindrica, Aspidosperma duckei and Apeiba echinata. Five trees of each species were used, and one wedge of DBH was collected from each of the five trees. Three 1 cm³ wooden blocks (1 cm x 1 cm x 1 cm) were removed from each wedge, under a 10x lens, oriented from the pith to the region close to the bark. Subsequently, five permanent blades were made. The elements that make up the wood were described according to BURGER's guidelines; RICHTER (1991) and IAWA (1989), through images obtained using the Zeiss Discovery v12 stereomicroscope with an attached digital camera and the necessary measurements were carried out using the Axio Vision 4.7 software. To prepare the maceration slides, small fragments of samples from the 1 cm3 wooden blocks were removed and submerged in a macerating solution of hydrogen peroxide and glacial acetic acid (1:1). As a result, it can be observed that the wood studied was anatomically characterized as short fiber wood, however, its length was greater than other exotic and native species. However, for a better indication of use, a more in-depth study on the quality of the wood studied and its potential for the forestry sector is recommended.
