Resumo: The bark in some forest species may represent a significant volume of the trunk, demanding the use of efficient methods to estimate bark volume indirectly through equations. The aim of this study was to evaluate bark volume and thickness in teak (Tectona grandis) trees planted at different densities. Volume data were used to evaluate the percentage of bark in different portions of the trunk. Averages were compared by the Tukey test (p < 0.05%) and regression analysis (polynomial model) was used to predict bark thickness along the trunk. The effect of spacing on bark thickness was compared by the model identity test. The percentage of bark in more densely planted teak trees was higher. The percentage of bark decreases from the base to the top of the tree trunk, with an average volume of green bark reaching 24% to 30% of the total volume. Increasing spacing promotes higher absolute average bark thickness.

O objetivo do trabalho foi avaliar o volume e a espessura de casca em árvores de Tectona grandis implantadas em diferentes densidades de plantio. Foram usados dados de cubagem para avaliar a porcentagem de casca em diferentes porções do fuste. As médias foram comparadas pelo teste de Tukey (p < 0,05) e também se empregou análise de regressão (modelo polinomial), para se estimar a espessura da casca das árvores ao longo do fuste. O efeito do espaçamento na espessura da casca foi comparado com o teste de identidade de modelos. O percentual de casca das árvores de teca é maior nos espaçamentos mais adensados. A porcentagem de casca vai diminuindo da base para o topo do fuste das árvores, sendo que em média o volume de casca verde chega a apresentar valores entre 24% a 30% do volume total. O aumento do espaçamento promove maior espessura média de casca das árvores.Embrapa Florestas2022-12-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/octet-streamhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/206710.4336/2022.pfb.42e201902067Pesquisa Florestal Brasileira; v. 42 (2022)Pesquisa Florestal Brasileira; Vol. 42 (2022)1983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/2067/1666Copyright (c) 2022 Diogo Guido Streck Vendruscolo, Felipe Vieira Cunha Neto, Isabel Matos Fragahttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessVendruscolo, Diogo Guido StreckCunha Neto, Felipe VieiraFraga, Isabel Matos2022-12-14T14:46:53Zoai:pfb.cnpf.embrapa.br/pfb:article/2067Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2022-12-14T14:46:53Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
