Resumo: Minquartia guianensis Aubl. (acariquara) occurs at Acre, Amazonas, Roraima, Pará and Amapá states, with a great market demand and utility in the Amazon region. It is used mainly in civil construction due to its high durability and singular beauty, because of reentrances in its trunk, resulting in high market value. Most of used trees present small diameters, what is a critical factor for their management and commercialization. Thus, the objective of this study was to evaluate M. guianensis diametric growth and cutting cycle through the analysis of time of passage among diameter classes, 31 years after logging, at Tapajós National Forest, Pará State, Brazil. Five treatments were established and in each one 12 permanent sample plots of 0.25 ha were installed. All trees with diameter at 1.3 m above ground level (DBH) ≥ 5 cm were measured from 1981 to 2012. Trees with DBH ≤ 50 cm have potential to be managed, due to the growth stagnation presented in larger diameter classes. These results may support silvicultural decisions to sustainable management.

(acariquara) ocorre nos estados do Acre, Amazonas, Roraima, Pará e Amapá, com grande procura de mercado e utilidade na região Amazônica. Seu principal uso é na construção civil, por apresentar alta durabilidade e reentrâncias em seu tronco, que a tornam de beleza singular e muito valorizada. A maioria das árvores utilizadas apresenta pequenos diâmetros, sendo este um fator crítico para seu manejo e comercialização. Portanto, objetivou-se avaliar o crescimento diamétrico e o ciclo de corte de M. guianensis, por meio da análise do tempo de passagem entre as classes diamétricas, no período de 31 anos, após a exploração florestal, na Floresta Nacional do Tapajós, estado do Pará. Foram estabelecidos cinco tratamentos, e em cada um foram instaladas 12 parcelas permanentes de 0,25 ha, nas quais foram medidas todas as árvores com diâmetro a 1,30 m do solo (DAP) ≥ 5 cm, de 1981 a 2012. As árvores com DAP ≤ 50 cm têm potencial para serem manejadas, em razão da diminuição do crescimento diamétrico a partir do DAP ≥ 50 cm. Esses resultados poderão servir de base para subsidiar decisões silviculturais no manejo sustentável da espécie.Embrapa Florestas2017-09-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/140610.4336/2017.pfb.37.91.1406Pesquisa Florestal Brasileira; v. 37 n. 91 (2017): jul./set.; 299-309Pesquisa Florestal Brasileira; Vol. 37 No. 91 (2017): jul./set.; 299-3091983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1406/589https://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessAndrade, Cinthia Grazielle Carvalhoda Silva, Márcio LopesTorres, Carlos Moreira Miquelino EletoRuschel, Ademir Robertoda Silva, Liniker Fernandesde Andrade, Dárlison Fernandes CarvalhoReis, Leonardo Pequeno2018-05-24T12:03:04Zoai:pfb.cnpf.embrapa.br/pfb:article/1406Revistahttps://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:2018-05-24T12:03:04Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
