Resumo: This study aims to construct definitive sites curves for native bracatinga stands (Mimosa scabrella Benth) in the metropolitan region of Curitiba. Data used was extracted from 648 pairs of values of dominant height and age. Ten mathematical models were tested for guide curve fitting. Selection of the best performing model was based on adjusted coefficient of determination (Raj 2), standard error of estimate in percentage (Syx%) and graphic analysis of residuals. Models were tested and the Chapman-Richards model was selected for construction of limit curves of site classes due to the biological significance of its coefficients, statistical performance and good distribution of residuals. Curve anamorphism and model validity were verified using the test proposed by Kirby (1975). Curve stability was demonstrated based on stem analysis data composing part of the database. Site classification for bracatinga stands was thus considered suitable and can potentially be applied to development of growth and yield equations for this particular species.

Os dados utilizados provieram de 648 pares de valores de altura dominante e idade. Foram testados 10 modelos matemáticos para o ajuste da curva guia. O modelo de melhor desempenho foi escolhido com base no coeficiente de determinação ajustado (Raj 2), erro padrão da estimativa percentual (Syx%) e análise gráfica de resíduos. Dentre os modelos testados o de Chapman- Richards foi selecionado para a construção das curvas limites das classes de sítio, em decorrência da significância biológica de seus coeficientes, desempenho estatístico e boa distribuição de resíduos. O anamorfismo das curvas e a validade do modelo foram verificados por meio de teste proposto por Kirby (1975). A estabilidade das curvas foi comprovada com base nos dados provenientes de análise de tronco que compunham parte da base de dados. Dessa forma, a classificação de sítios realizada para os bracatingais foi considerada adequada e, poderá ser aplicada no desenvolvimento de equações de crescimento e produção para essa espécie.Universidade Federal de Lavras (UFLA)2015-05-122017-08-01T20:13:52Z2017-08-01T20:13:52Z2017-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfMACHADO, S. do A. et al.
