Resumo: The objective of this study was to calculate the ratio of Liocourt in natural forest with 50 hectares of Araucaria angustifolia. The diameter distribution behaved as expected for native forests, generating a distribution curve similar to an inverted-J. The forest showed 456 araucaria trees per hectare with diameter at breast hight (DBH) above 10 cm and basal area of 24.64 m² ha-1. The value of the Liocourt quotient was 1.3, and 54 trees per hectare with 40 cm of DHB can be removed, with a reduction of 2.70 m² ha-1 of basal area or 135 m² total basal area and 34 trees per hectare for a 50 cm of DBH with a reduction of 1.9 m² ha-1 or 95 m² total basal area. Considering only the commercial classes (DBH ≥ 40 cm) this withdrawal represents a reduction of 9.5% for the basal area to the diameter of 40 cm and 6.9% to the diameter of 50 cm. doi: 10.4336/2012.pfb.32.70.111

A distribuição diamétrica se comportou como o previsto para florestas nativas, gerando uma curva de distribuição semelhante a um J-invertido. A floresta apresentou 456 árvores de araucária por hectare com diâmetro à altura do peito (DAP) acima de 10 cm e área basal de 24,64 m² ha-1. O valor do quociente ‘q’ de Liocourt foi de 1,3, podendo-se realizar a retirada de 54 árvores por hectare para um diâmetro de 40 cm, com redução de 2,70 m² ha-1 de área basal ou 135 m² para o total da área e 34 árvores por hectare, para um diâmetro de 50 cm e uma redução de 1,9 m² ha-1 ou 95 m² total de área basal. Considerando-se somente as classes comerciais (DAP ≥ 40 cm) esta retirada representa uma redução de 9,5% em área basal para o diâmetro de 40 cm e de 6,9% para o diâmetro de 50 cm. doi: 10.4336/2012.pfb.32.70.111Embrapa Florestas2012-06-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/279Pesquisa Florestal Brasileira; v. 32 n. 70 (2012): abr./jun.; 227Pesquisa Florestal Brasileira; Vol. 32 No. 70 (2012): abr./jun.; 2271983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/279/257Hess, André Felipeinfo:eu-repo/semantics/openAccess2018-03-20T18:49:55Zoai:pfb.cnpf.embrapa.br/pfb:article/279Revistahttps://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:2018-03-20T18:49:55Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
