Resumo: Plant morphometric variables are used to estimate interdimensional relations, and their analysis is important to obtain information on the plant’s stability, vitality, and yield. The aim of this study was to determine the morphometric variables, interdimensional relations, and the yield of jatropha grown in a silvopastoral system. Forty-five trees were measured for three years following cultivation in Latossolo, West Paraná. The characteristics under analysis were as follows: stem diameter, height, crown diameter, crown length, crown area, crown proportion, slenderness ratio, salience index, coverage index, crown formation, number of branches, and yield. The assessments were carried out between January 2011 and July 2011. Stem diameter showed the best correlation with jatropha crop yield. For the same variable, significant regression models were obtained for the following: plant height, crown diameter, slenderness ratio, and coverage index.

O objetivo deste trabalho foi determinar as variáveis morfométricas, as relações interdimensionais e a produtividade de pinhão manso cultivado em sistema silvipastoril. Foram mensuradas 45 árvores aos três anos após o plantio em Latossolo no Oeste do Paraná. As características analisadas foram: diâmetro do caule, altura, diâmetro da copa, comprimento da copa, área da copa, proporção da copa, grau de esbeltez, índice de saliência, índice de abrangência, formal da copa, número de ramos e a produtividade. As avaliações foram realizadas entre janeiro de 2011 e julho de 2011. O diâmetro do caule foi a variável que melhor se correlacionou com o a produtividade da cultura do pinhão-manso. Para essa variável, também foram obtidos modelos de regressão significativos para: altura da planta, diâmetro da copa, grau de esbeltez e índice de abrangência.UEL2014-04-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1091310.5433/1679-0359.2014v35n2p613Semina: Ciências Agrárias; Vol. 35 No. 2 (2014); 613-624Semina: Ciências Agrárias; v. 35 n. 2 (2014); 613-6241679-03591676-546Xreponame:Semina.
