Abstract

Abstract Wood quality is related to the characteristics and properties of this material. Understanding the factors that can impact the wood formation is fundamental in the indications for use. The aim of this study was to evaluate the influence of different planting densities on the wood quality and the radial profile on some physical and anatomical characteristics of young trees of Tectona grandis. Nine trees were evaluated in three planting densities: 6 x 2 m; 5 x 2 m; and 4 x 2 m. All trees were subjected to analysis of acoustic tomography, X-ray densitometry, and fiber characterization. Multivariate associations between the variables of interest were evaluated according to the planting spacing and the radial profile by principal component analysis. The results indicated that the wood characteristics of young teak trees are influenced, mainly, by the radial variation (pith-bark).

Summary

Introduction

Tectona grandis L. f., popularly known as teak, is a deciduous and pioneer species belonging to the Lamiaceae family. It is considered one of the most valuable tropical timber species, whose wood is in high demand in the luxury markets, in the civil industry, and in the manufacture of furniture (Kollert & Kleine, 2017). It occurs naturally in four countries in South and Southeast Asia, namely Myanmar, India, Lao People’s Democratic Republic, and Thailand. In Brazil, in 2018, teak plantations occupied 15.89% of the total area with unconventional forest crops, representing the third-largest crop in extension (IBÁ, 2019)
