Resumo: http://dx.doi.org/10.5902/198050985085The objective of this paper was model the shape, compare the efficiency of the total volume estimated with the 5th grade polynomial, with and without data stratification by an artificial form quotient and build the assortment table. The data came from Pinus taeda L. stands, managed by a sawmill company, with two thinning and coppicing, plantation of 1.600 trees/ha and spacing of 2,50 x 2,50 m, from Klabin S.A., in Telêmaco Borba,  Paraná state. The field data was stratified in three form quotient classes defined by the diameter of 70% total height and breast height diameter. The trunk classification in assortments was accurate and the volume obtained with the integrated equations presented small residues, without tendency. The results proved the viability of the data stratification by form quotients to obtain better estimative of tree assortments.

As árvores amostradas foram medidas em povoamentos manejados para serraria, com dois desbastes, sendo o plantio inicial de 1.600 árvores/ha, em espaçamento de 2,50 x 2,50 m, localizados na Klabin S.A., em Telêmaco Borba-PR. Para fins de modelagem os dados foram estratificados em classes de quociente de forma calculado a 70% da altura. A classificação das partes do tronco em sortimentos foi acurada sendo que o volume estimado a partir das integrais das equações de afilamento apresentou valores residuais pequenos e sem tendências, comprovando a viabilidade da estratificação dos dados em classes de quociente de forma quando do ajuste de equações para a obtenção dos sortimentos.Universidade Federal de Santa Maria2012-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/508510.5902/198050985085Ciência Florestal; Vol. 22 No. 1 (2012); 125-135Ciência Florestal; v. 22 n. 1 (2012); 125-1351980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/5085/3078Souza, Carlos Alberto Martinelli deFinger, César Augusto GuimarãesSchneider, Paulo RenatoSilva, Gilson Fernandes daThomas, Claúdioinfo:eu-repo/semantics/openAccess2014-08-28T23:33:03Zoai:ojs.pkp.sfu.ca:article/5085Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2014-08-28T23:33:03Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
