Resumo: This study aimed to determine the artificial form factor and confection table form factor for teak in Brasnorte and Santo Antônio do Leverger, Mato Grosso State, Brazil. A hundred tress were measured and 162 were cubated in stands from 20 to 10 years of age. The volume was estimated using Smalian and form factors by the reason between the estimated and cylindrical volumes. Sixteen models of artificial the form factor werw tested, and the equation ln(f1,3)=0,774+0,697.ln(d0,5/d²)-0,647.ln(d0,1/d²)+0,199.ln(1/h.d) presented the best fit with the diameter of Hohenadl (d0.5 e d0.1) estimated by the respective equations: ln(d0,5)= -1,066.ln(1/d)+0,234.ln(1/h) and ln(d0,1)= 0,753 – 0,535.ln(h/d²)+0,199.ln(h). The form factor table covered a amplitude from 0.4038 to 0.6443.

The form factor table covered a amplitude from 0.4038 to 0.6443.A Tectona grandis Linn F. foi introduzida no Estado de Mato Grosso no final da década de 1960 e, a cada ano, novos plantios são realizados com o intuito de substituir as madeiras nativas de uso nobre. Os plantios de teca são realizados, na sua maioria, em sistemas de mosaico, sendo este o maior ganho dessa espécie madeireira. Para este estudo, foram realizados levantamentos em povoamentos de teca nos municípios de Santo Antônio do Leverger e Brasnorte, em propriedades das empresas Brasteca e Berneck, respectivamente. Os plantios estudados possuem não mais do que 11 anos de idade, com a possibilidade de rotações curtas que permitem a discussão da importância de se processar madeira com pequena dimensão. Este trabalho teve como objetivo determinar o fator de forma artificial e confeccionar a tabela de fator de forma para a teca nas regiões em estudo. A equação ln(f1,3)=0,774+0,697.ln(d0,5/d²)-0,647.ln(d0,1/d²)+0,199.ln(1/h.d) apresentou o melhor ajuste, sendo os diâmetros relativos de Hohenadl (d0,5 e d0,1) estimados pela respectivas equações: ln(d0,5)= -1,066.ln(1/d)+0,234.ln(1/h) e ln(d0,1)= 0,753 – 0,535.ln(h/d²)+0,199.ln(h).Embrapa Florestas2010-11-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/mswordhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/14910.4336/2010.pfb.30.63.191Pesquisa Florestal Brasileira; v. 30 n. 63 (2010): jul./set.; 191Pesquisa Florestal Brasileira; Vol. 30 No. 63 (2010): jul./set.; 1911983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/149/132https://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/149/958Drescher, RonaldoPelissari, Allan LibanioGava, Fernando Henriqueinfo:eu-repo/semantics/openAccess2017-04-28T13:14:02Zoai:pfb.cnpf.embrapa.br/pfb:article/149Revistahttps://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:2017-04-28T13:14:02Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
