Abstract

Provenance testing can provide information on silvicultural behavior and wood quality of species for selection of genetic material for different locations and conservation of the genetic base. The aim of this work was to study the longitudinal variation of basic density, volumetric shrinkage and microfibril angle of wood from two provenances (Assis and Bauru) of Handroantus impetiginosus planted in Luiz Antonio SP. After 26 years of planting, twelve trees were felled, six from each provenance. According to the results obtained, it could be concluded that the analysis of variance (ANOVA) showed that for the provenance there was a significant variation for the volumetric shrinkage of the wood and for basic wood density and microfibril angle the significance of variation did not occur. The basic wood density varied significantly between the different positions, at the height of the tree and for volumetric shrinkage, and for the microfibril angle it did not occur. There is a positive relationship between tree height and basic wood density of wood, for Assis and Bauru provenances.

Summary

Introduction

Forestry is currently faced with major challenges related to aspects such as climate change, combating desertification, biodiversity conservation, soil and water. Some challenges posed in forestry involve choosing an adequate treatment method and combining forestry production with other benefits and ecosystem services. In this sense, reconciling the economy with ecology, the combination of environmental, social and economic aspects presents great relevance to forestry, in order to contribute to sustainable development, i.e. where the forestry of native species is mainly oriented towards different uses and functions of forest settlement is a generator of new activities, jobs and income, contributing to the development of local communities and the country in general. The use of native species from reforestation can be another viable alternative, to be used by the Brazilian market. One of the native species with potential for use in reforestation is the Handroantus impetiginosus, which has been highlighted for its survival and productivity in pure plantations, being seen as a great potential for consumption and wood production.
