Resumo: | This study aimed to test the hypothesis that crown length affects the hypsometric relationship. We used data from diameter measured at 1.3 m above ground level (DBH) and total heights of 337 trees of Araucaria angustifolia (Bertol.) O. Kuntze from an urban remnant of Araucaria Forest with 15.24 ha, located in Curitiba, PR, Brazil. These trees were grouped into classes of crown length. Six hypsometric models were adjusted to the data for each class and for the entire data set. The best model was chosen based on the standard error of estimate in percentage, index of Schlaegel, and graphical analysis of residuals. The ranking indicated Trorey as the best model. The models identity test of Graybill applied to the Trorey model indicated that crown length influenced the hypsometric relationship of the araucarias in the study area. |

Os dados utilizados são provenientes da medição de diâmetro a 1,30 m do solo (DAP) e respectivas alturas totais e do fuste de 337 indivíduos de Araucaria angustifolia (Bertol.) O. Kuntze de um fragmento de 15,24 ha de Floresta Ombrófila Mista situado na região urbana de Curitiba. Estas árvores foram agrupadas em classes de comprimento de copa. Foram ajustados seis modelos hipsométricos aos dados de cada classe e para todo o conjunto de dados. O melhor modelo foi escolhido com base no erro padrão da estimativa em porcentagem, Índice de Schlaegel e análise gráfica de resíduos. O ordenamento indicou que o modelo de melhor ajuste aos dados foi o de Trorey. O teste de identidade de modelos de Graybill aplicado ao modelo de Trorey indicou que o comprimento de copa influenciou a relação hipsométrica das araucárias da área de estudo.Embrapa Florestas2015-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/49310.4336/2015.pfb.35.83.493Pesquisa Florestal Brasileira; v. 35 n. 83 (2015): jul./set.; 343-351Pesquisa Florestal Brasileira; Vol. 35 No. 83 (2015): jul./set.; 343-3511983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/493/445Copyright (c) 2015 Sebastião do Amaral Machado, Yuri Accioly, Rodrigo Geroni Mendes Nascimento, Luís César Rodrigues da Silva, Claudia Carla Cardozohttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessMachado, Sebastião do AmaralAccioly, YuriNascimento, Rodrigo Geroni Mendesda Silva, Luís César RodriguesCardozo, Claudia Carla2017-04-28T12:42:02Zoai:pfb.cnpf.embrapa.br/pfb:article/493Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2017-04-28T12:42:02Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
