Abstract: RESUMOO objetivo deste estudo foi selecionar um modelo de taper considerando a influência da estratificação dos dados em quatro diferentes classes de diâmetro. Palavras-chave: Biometria Florestal, floresta comercial e taper. Stem Profile Equations for the Eucalyptus camaldulensisDehnh in South Central Tocantins ABSTRACTThe objective of this study was to select a model of taper considering the influence of stratification of data in four different diameter classes. Six models of taper were evaluated for a commer… Show more

“…Taper functions have been fit at site specific basis, such as for specific spacing (Vendruscolo et al 2016), for age classes (Koehler et al 2016) and diameter classes (Ribeiro and Andrade, 2016). Knowing the factors affecting tree shape allows one to include them into modeling (Gomat et al 2011) and to use the mixed models approach, randomizing one or more coefficients in the model (Scolforo et al 2018b), which allows generalizing the fit and to amplify the modeling use.…”

“…All these management approaches have to be considered when modeling taper, since stem shape is affected by several stand attributes, such as species, age, spacing, and site quality (Burkhart and Tomé, 2012). Considering all these factors when modeling taper can lead to a large number of equations to address them, for example, describing different spacing (Vendruscolo et al 2016), age classes (Koehler et al 2016) or diameter classes (Ribeiro and Andrade, 2016).…”

“…Among the simple models, Demaerschalk's is the most used one in Brazil. Studies by Leite et al (2011), Silva et al (2011), Muller et al (2014, and Ribeiro and Andrade (2016) are examples of its application. Simple models are those in which a single function represents the entire shape of the stem, from its base to its top.…”

“…Neste sentindo, os estudos brasileiros sobre equações de perfil do tronco de árvores deram maior enfoque em plantios com eucalipto (Ribeiro & Andrade, 2016;Azevedo et al, 2017;Cerqueira et al, 2018;Souza et al, 2018;Farias, Marcos & Natalia, 2019); com pinus (Fischer et al, 2001); com outras espécies (Muller et al, 2014). Há, ainda, que se reportar aos trabalhos feitos em floresta nativa (Lanssanova et al, 2013;.…”
