Os dados utilizados são oriundos de uma rede de parcelas experimentais, com áreas iguais a 1505 e 1548 m², instaladas em dois locais no município de Água Boa, Mato Grosso, e compreendendo 12 espaçamentos. Foram consideradas nove repetições por espaçamento em delineamento inteiramente casualizado. As medições de altura total e diâmetro a 1,3 m de altura foram realizadas nas idades de 26, 42, 50 e 78 meses. Para a modelagem da distribuição diamétrica, utilizou-se a função Weibull e um conjunto de equações para estimar os parâmetros da função em uma idade futura. A idade técnica de desbaste foi definida a partir da aplicação do Método dos Ingressos Percentuais, com utilização do modelo expolinear. A estagnação do crescimento ocorreu mais cedo nos espaçamentos mais adensados, apresentando menores idades técnicas de desbaste, as quais variaram entre 6 e 8 anos. O método de ingressos percentuais e modelos de distribuição diamétrica são eficientes para definição da idade técnica de desbaste em povoamentos de teca com diferentes espaçamentos.The objective of this study was to identify the technical age for the first thinning in Tectona grandis L.f. stands considering different spacing. The data are from an experimental net of sampling plots, with areas equal to 1505 and 1548 m², installed in two sites at Água Boa municipality, Mato Grosso state, considering twelve different spacing. Nine replications were considered per spacing, in a completely randomized design. Measurements of total height of the trees and diameter at 1.3 m in height were taken at the ages of 26, 42, 50 and 78 months. To model the diameter distribution, the Weibull function and a set of equations to estimate the values of its parameters in a future age were used. The technical age of thinning was defined based on the application of the Percentage Ingrowth Method, using the expo-linear model. Stagnation of growth occurred earlier in the denser spacing, with a lower technical age of thinning, which ranged between 6 and 8 years. The percentage ingrowth method and the diameter distribution models are efficient to define the technical age of thinning in teak stands with different spacing.Outra AgênciaporUniversidade Federal de Minas GeraisUFMGBrasilICA - INSTITUTO DE CIÊNCIAS AGRÁRIASScientia ForestalisTeca (Árvore) -- EspaçamentoDesbastes florestalIdade técnica do primeiro desbaste de povoamentos de teca em diferentes espaçamentosTechnical age for the first thinning of teak stands in different spacingsinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://www.ipef.br/publicacoes/scientia/nr116/cap11.pdfReginaldo Antonio MedeirosHaroldo Nogueira de PaivaHélio Garcia LeiteThiago Taglialegna SallesCarlos Alberto Araújo JúniorFlávio Siqueira Davilainfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain; charset=utf-82042https://repositorio.ufmg.br/bitstream/1843/43191/1/License.txtfa505098d172de0bc8864fc1287ffe22MD51ORIGINALIdade técnica do primeiro desbaste de povoamentos de teca em diferentes espaçamentos.pdfIdade técnica do primeiro desbaste de povoamentos de teca em diferentes espaçamentos.pdfapplication/pdf2902852https://repositorio.ufmg.br/bitstream/1843/43191/2/Idade%20t%c3%a9cnica%20do%20primeiro%20desbaste%20de%20povoamentos%20de%20teca%20em%20diferentes%20espa%c3%a7amentos.pdf6c000edb5e9e3e03b471a14f867869e5MD521843/431912022-07-12 12:24:19.447oai:repositorio.ufmg.br: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Repositório InstitucionalPUBhttps://repositorio.ufmg.br/oaiopendoar:2022-07-12T15:24:19Repositório Institucional da UFMG - Universidade Federal de Minas Gerais (UFMG)false
