              <text>O correto dimensionamento de experimentos deve ser utilizado para que se possa reduzir o erro experimental e com isso, maximizar a precisão das informações obtidas. O objetivo deste trabalho foi estimar o número mínimo de famílias e de plantas por parcela para avaliação de caracteres de raiz em uma população de cenoura cultivada em sistema agroecológico. Os ensaios foram conduzidos no verão de 2006/2007 em duas propriedades com cultivo agroecológico em Brasília: Associação Mokiti Okada, que segue modelo de Agricultura Natural em Brazlândia-DF e Núcleo Rural Taguatinga, seguindo modelo de Agricultura Orgânica em Taguatinga-DF. Foram avaliadas 100 famílias de meio-irmãos de cenoura dispostas em delineamento de blocos casualizados com duas repetições e parcelas de 1 m². Foram colhidas 20 plantas competitivas por parcela e avaliadas individualmente para os caracteres comprimento de raiz, diâmetro da raiz, massa da raiz, diâmetro do xilema da raiz, relação diâmetro do xilema/diâmetro da raiz, tipo de ponta da raiz, tipo de ombro da raiz, parâmetro a* para os tecidos xilema e floema. Foi realizada análise de variância conjunta e para cada sistema, com informação entre e dentro de parcelas. Foram realizadas ainda análises de representatividade do número mínimo de famílias e de plantas para representar uma população de cenoura. Foi verificado que uma amostra de 18 plantas competitivas/parcela coletadas em ensaios com 2 repetições, bem como de 74 famílias, são suficientes para garantir uma adequada avaliação de famílias meio-irmãos de cenoura para os caracteres estudados.The correct experiment design should be used to reduce the experimental error and, with that, maximize the precision of the information obtained. The objective of this work was to estimate the minimum number of families and of plants per plot for evaluation of root traits in a carrot population cultivated in agroecologic systems. The essays were conducted in the summer of 2006/2007 in two agroecologic properties in Brasília: 'Associação Mokiti Okada', which follows model of Natural Agriculture in Brazlândia and 'Núcleo Rural Taguatinga', following model of Organic Agriculture in Taguatinga, Brazil. We evaluated 100 half-sib families of carrot arranged in randomized block design with two replications and plots of 1 m². Twenty competitive plants per plot were harvested and individually evaluated for the traits: root length, root diameter, root mass, root xylem diameter, relationship of xylem diameter/root diameter, type of root tip, type of root shoulder, parameter a* of root xylem and phloem. Joint variance analysis of the group and of each system, were performed with information between and inside plots. Analyses of representativity minimum number of families and of plants to represent a carrot population were performed. A sample of 18 plants competitive/plot collected in essays with 2 replications, as well as 74 families, are enough to guarantee an appropriate evaluation of carrot half-sib families for the traits studied.</text>
