Resumo: The variation of the annual growth in different heights of the stem of Pinus taeda L. was studied through the stem analysis, accomplished in dominant and medium stratum trees. Cross sections were collected along the stem from 9 sample trees on the base, breast height diameter (BHD) and after these positions, at every meter. The sampling was constituted of 4 trees coming from Canela, Rio Grande do Sul, in a 17-years-old stand, submitted to one thinning, and 6 trees from Ponte Alta do Norte, Santa Catarina, in a 34-years-old stand, submitted to five thinnings. The results, expressed in percentage of the basal area increment in several positions of the tree height, showed strong variation in the annual deposition of wood along the stem in function of the populational density, characterizing the effects of the competition and of the thinning liberation. Trees subjected to the competition showed larger growth on top parts of the stem, while trees under smaller competition presented larger growth on lower positions, easily identified by the form and inclination of the increment curves.

Foram coletadas secções transversais ao longo do fuste de 9 árvores-amostra, tomadas na base, à altura do peito (DAP), e após, a cada metro. A amostragem foi constituída de 4 árvores provenientes de Canela, Rio Grande do Sul, em floresta com 17 anos de idade, submetida a um desbaste, e 5 árvores de Ponte Alta do Norte, Santa Catarina, em floresta com 34 anos, submetida a cinco desbastes. Os resultados, expressos na forma percentual do incremento em área basal na posição "i", sobre o incremento em área basal ao nível do DAP, mostraram a forte variação na deposição anual de lenho ao longo do fuste em função da densidade populacional, caracterizando os efeitos da competição e da liberação pela execução do desbaste. Árvores sujeitas à competição mostraram maior crescimento nas partes superiores do fuste, enquanto que árvores sob menor concorrência apresentaram maior crescimento em posições inferiores, facilmente identificadas pela forma e inclinação das curvas de incremento.Universidade Federal de Santa Maria2007-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/195510.5902/198050981955Ciência Florestal; Vol. 17 No. 3 (2007); 239-246Ciência Florestal; v. 17 n. 3 (2007); 239-2461980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1955/1209Andrade, César MartinsFinger, César Augusto GuimarãesThomas, CláudioSchneider, Paulo Renatoinfo:eu-repo/semantics/openAccess2017-05-12T13:56:55Zoai:ojs.pkp.sfu.ca:article/1955Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-12T13:56:55Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
