Resumo: Forests are important carbon sinks that contribute to climate change mitigation. Quantifying the carbon stock is critical for measuring such mitigation potential. Araucaria angustifolia (Bert.) O. Ktze. Araucariaceae is a key forest species in southern Brazil, due to its ecological and economic importance. This study aimed at comparing two procedures for estimating individual carbon stock (C) of A. angustifolia, in pure stands established in the southern Paraná State, Brazil. Individual carbon stocks were determined for thirty trees, as well as correlations between C, dendometric variables, Biomass Expansion Factor (BEF) and Root-to-Shoot Ratio (R). Regression equations of C, concerning Diameter Breast Height (DBH) and total height (H), were adjusted and compared to trunk volume (V) estimates combined with BEF and R. DBH and H showed high correlation to C, what did not happen to tree age, BEF and R. The regression equations of C, concerning DBH and H, adjusted well to the data set, providing reliable estimates. The same happened to the volume equations combined with expansion factors, which also provided statistically acceptable estimates. No difference was observed between the two procedures tested, being both reliable for estimating the individual carbon stock.

Quantificar o estoque de carbono é fundamental para dimensionar este potencial de mitigação. Araucaria angustifolia (Bert.) O. Ktze. Araucariaceae é uma espécie florestal chave no sul do Brasil, devido à sua importância ecológica e econômica. Este estudo visou a analisar comparativamente dois procedimentos de estimativa do estoque individual de carbono (C) de A. angustifolia, em povoamentos implantados no sul do Estado do Paraná. Foram determinados os estoques de carbono em trinta árvores, bem como as correlações entre C, variáveis dendrométricas, Fator de Expansão de Biomassa (FEB) e Razão de Raízes (R). Equações de regressão de C, em função do Diâmetro à Altura do Peito (DAP) e altura total (H), foram ajustadas e comparadas com estimativas do volume do fuste (V) combinadas com FEB e R. O DAP e H se correlacionaram significativamente com C, o que não ocorreu com a idade, FEB e R. As equações de regressão de C, em função de DAP e H, se ajustaram bem aos dados e geraram estimativas acuradas. O mesmo ocorreu em relação às equações de volume, que, combinadas com os fatores de expansão, também propiciaram estimativas estatisticamente aceitáveis. Não houve diferença entre os dois procedimentos testados, sendo ambos acurados para estimar o estoque de carbono individual.Escola de Agronomia - Universidade Federal de Goiás2014-03-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionMétodos Quantitativosapplication/pdfhttps://revistas.ufg.br/pat/article/view/22358Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 44, n. 1, Jan./Mar. 2014; 1-8Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 44, n. 1, jan./mar. 2014; 1-8Pesquisa Agropecuária Tropical; v. 44, n. 1, jan./mar. 2014; 1-81983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/22358/16095Copyright (c) 2020 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessSanquetta, Carlos RobertoDalla Corte, Ana PaulaMognon, FranceloMaas, Greyce Charllyne BenedetRodrigues, Aurélio Lourenço2020-07-10T16:07:23Zoai:ojs.revistas.ufg.br:article/22358Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:55:59.826799Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true
