Resumo: This study, conducted in a 27-year-old Araucaria angustifolia stand in the municipality of Quedas do Iguaçu (PR) county, aimed to estimate tree components, understory and accumulated litter biomasses. Biomass was estimated through regression equation adjustments, with 21 trees felled, distributed among 7 diametric classes, and with litter and understory based on known sample unit areas. Total stand biomass was 241.92 Mg ha-1, with 82.2% composed of Araucaria angustifolia, 9.6% composed of understory and 8.2% composed by litter. Considering only Araucaria angustifolia, the biomass was of 198.62 Mg ha-1, composed of wood (51.5%), bark (14.7%), roots (13.0%), lives branches (11.8%), aciculated branches (6.6%) and dead branches (0.5%). Relative biomass production for the wood component may be low, when compared to other forest species, mainly due to the high allocation in the bark component.

A biomassa foi estimada por meio do ajuste de equações de regressão, com coleta de 21 árvores distribuídas em sete classes diamétricas, serapilheira e o sub-bosque com base em unidades amostrais de área conhecida. A biomassa total do povoamento foi de 241,92 Mg ha-1, sendo 82,2% de Araucaria angustifolia, 9,6% de sub-bosque e 8,2% de serapilheira. Considerando apenas a biomassa de Araucaria angustifolia, 198,62 Mg ha-1, madeira do tronco (51,5%), casca do tronco (14,7%), raiz (13,0%), galhos vivos (11,8%), grimpas (ramos aciculados) (8,6%) e galhos mortos (0,5%). A produção relativa de biomassa no componente madeira do tronco pode ser menor, quando comparado com outras espécies florestais, sobretudo por causa da elevada alocação no componente casca do tronco.Universidade Federal de Santa Maria2011-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/274710.5902/198050982747Ciência Florestal; Vol. 21 No. 1 (2011); 53-62Ciência Florestal; v. 21 n. 1 (2011); 53-621980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/2747/1672Schumacher, Mauro ValdirWitschoreck, RudiCalil, Francine NevesLopes, Vicente GuilhemeViera, Márcioinfo:eu-repo/semantics/openAccess2017-05-04T11:43:00Zoai:ojs.pkp.sfu.ca:article/2747Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-04T11:43Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
