Resumo: Defining a suitable size and shape for experimental plots of candeia is an alternative for ensuring correct interpretations and consistent conclusions about the cultivation of this species. The objective of this work was to define optimal size, convenient sizes and suitable shape for experimental plots of Eremanthus erythropappus, for evaluation of main dendrometric characteristics in experimental plantations. To attain that, a uniformity trial was used containing 400 plants, all of which had circumference, height and volume measured. 31 combinations of size/shape were simulated for experimental plots. For determination of optimal size, three curvature methods and one method based on the segmented linear plateau model were used. For determination of suitable shape, the criterion of relative information and coefficient of variation was used. Convenient size was estimated by the Hatheway method. Results led to the conclusion that the size of experimental plots of candeia capable of allowing analysis of main dendrometric characteristics should be 60 useful plants, the most suitable shape being a rectangular configuration of 2×30 (rows × plants). Convenient size is a very flexible parameter and allows adaptations depending on the conditions, characteristics and limitations of the experiment in question.

Assim, neste trabalho, objetivou-se defi nir o tamanho ótimo, tamanhos convenientes e forma adequada de parcelas experimentais para Eremanthus erythropappus, para avaliação das principais características dendrométricas em plantios experimentais. Para isso, foi utilizado um ensaio de uniformidade contendo 400 plantas, as quais tiveram a circunferência, a altura e o volume determinados. Foram simuladas 31 combinações de tamanho/forma de parcelas experimentais. Para a determinação do tamanho ótimo, foram utilizados três métodos de curvatura e um método baseado no modelo linear segmentado com platô. A forma adequada foi determinada a partir do critério de informação relativa e coefi ciente de variação. O tamanho conveniente foi estimado pelo de método Hatheway. Os resultados e as conclusões obtidas foram as de que o tamanho de parcelas experimentais para candeia, de modo a permitir análise das principais características dendrométricas, deve ser de 60 plantas úteis, sendo a conformação retangular 2×30 (linhas × plantas) a forma mais adequada. O tamanho conveniente é muito fl exível e permite adequação do tamanho da parcela experimental com as condições, características e limitações do experimento.Universidade Federal de Lavras (UFLA)2015-05-112017-08-01T20:13:20Z2017-08-01T20:13:20Z2017-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfOLIVEIRA, G.
