Resumo: | This study was developed in order to model the growing space for Araucaria angustifolia (Bertol.) Kuntze trees. A total of 869 Parana pine trees were sampled in three municipalities in southern Brazil, being 175 trees with free growing of competition in the municipalities of Canoinhas (SC state) and Lages (SC state), and 694 under influence of competition in natural forest in the municipalities of São Francisco de Paula (RS state) and Lages (SC state). In each tree was measured diameter at breast height, total height and crown rays following the directions of the cardinal points. The crown diameter was determined by doubling the value of the average radius of the crown. Three models were fitted and evaluated the fit statistics, accuracy and residual graphical analysis, according to the municipality and growth condition. When comparing the equations, covariance analysis indicated that there is no significant difference between the level and slope of the crown diameter equations of open growth trees and under competition in different places where data were sampled. A single equation was defined to estimate the crown diameter as a function of the diameter at breast height for this species. |

Kuntze. Um total de 869 araucárias foram amostradas em três municípios no sul do Brasil, sendo 175 árvores com crescimento livre de competição nos municípios de Canoinhas-SC e Lages-SC, e 694 sob influência da competição em floresta natural nos municípios de São Francisco de Paula-RS e Lages-SC. Em cada árvore, foi medido o diâmetro a altura do peito, altura total e raios de copa seguindo as direções dos pontos cardeais. O diâmetro de copa foi determinado dobrando o valor do raio médio da copa. Três modelos foram ajustados e avaliados quanto ao ajuste, à precisão e à análise gráfica dos resíduos, segundo o município e a condição de crescimento. Na comparação das equações, a análise de covariância não indicou diferença significativa entre nível e inclinação das equações de diâmetro de copa de árvores livres e sob competição nos diferentes locais em que os dados foram amostrados. Uma única equação foi definida para estimar o diâmetro de copa em função do diâmetro a altura do peito para a espécie.Universidade Federal de Santa Maria2018-06-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3208510.5902/1980509832085Ciência Florestal; Vol. 28 No. 2 (2018); 725-734Ciência Florestal; v. 28 n. 2 (2018); 725-7341980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/32085/pdfCopyright (c) 2018 Ciência Florestalinfo:eu-repo/semantics/openAccessCosta, Emanuel ArnoniFinger, César Augusto GuimarãesFleig, Frederico Dimas2018-06-29T18:37:12Zoai:ojs.pkp.sfu.ca:article/32085Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2018-06-29T18:37:12Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
