Resumo: | The objective of this work was to determine the suitable sample size, to detect statistical differences in the analysis of variance of xylem characters, in annual shoots of avocado trees. For this, xylem characters of three trees with contrasting height were registered for frequency, area, perimeter and diameter of xylem vessels. Starting from 50 observations from each tree, a total of 5.000 non parametric bootstraps were done for each of the replicates from 2 to 50 microscopic fields. Starting from a sample size of 15 replicates, the deviations in the five statistical estimates are minimal, so it is proposed as the minimum for sampling the mentioned variables. |

Para esto, fueron registradas en tres árboles con altura contrastante las variables frecuencia, área, perímetro y diámetro de los vasos del xilema. A partir de 50 observaciones de cada árbol, se realizaron 5.000 remuestreos no paramétricos, para cada repetición de 2 a 50 campos microscópicos. A partir del tamaño de muestra de 15 repeticiones, las desviaciones en los cinco estadísticos son mínimas, por lo que se propone como el mínimo para el muestreo de dichas variables.The objective of this work was to determine the suitable sample size, to detect statistical differences in the analysis of variance of xylem characters, in annual shoots of avocado trees.
