| description | The scarce knowledge about the growth and development of the species of arid and semiarid zones in Mexico, has generated an over-use. Among the most important economically in Coahuila is the candelilla, of which the technical information available for decision-making in management is limited. Therefore, the objectives were: a) to group six municipalities based on the individual production of biomass evaluated in 10 natural populations of Euphorbia antisyphilitica Zucc. and, b) adjust allometric models to estimate the biomass of E. antisyphilitica in different growing conditions in the center and south of Coahuila. With an analysis of variance and the minimum significant difference, the municipalities were grouped; for each group, models were adjusted, using the ordinary least squares method. Three biomass production groups were obtained per individual (GI, GII and GIII). The models to estimate the total green biomass (kilogram per individual) for each group, resulted with an R2Ajus higher than 0.86, in the first two groups, and for GIII it was 0.64, the RMSE (root mean square error) was lower than 0.425 and the parameters of the models were significant (p < 0.05), in the four cases. In addition, the four selected models presented normality, homogeneity of variances and the nonexistence of collinearity between variables. The selected models are statistically reliable to estimate the biomass by individuals of each group considered in this study, so they can be a useful tool in the development of management plans for the use of candelilla. |

El escaso conocimiento sobre el crecimiento y desarrollo de las especies de zonas áridas y semiáridas en México ha generado un sobreaprovechamiento. Entre las especies más importantes económicamente en Coahuila está la candelilla, cuya información técnica disponible para la toma de decisiones en el manejo es limitada. Por lo anterior, los objetivos del presente trabajo fueron a) agrupar seis municipios con base en la producción individual de biomasa evaluada en 10 poblaciones naturales de Euphorbia antisyphilitica Zucc. y b) ajustar modelos alométricos para estimar la biomasa de E. antisyphilitica en diferentes condiciones de crecimiento, en el centro y sur de Coahuila. Con un análisis de varianza y la diferencia mínima significativa, se agruparon los municipios; para cada grupo se ajustaron modelos, mediante el método de mínimos cuadrados ordinarios. Se obtuvieron tres grupos de producción de biomasa por individuo (GI, GII y GIII). Los modelos para estimar la biomasa total verde (kilogramo por individuo) para cada grupo, resultaron con R2Ajus superiores a 0.86, en los primeros dos grupos, y de 0.64 para GIII. La RCME (raíz del cuadrado medio del error) fue inferior a 0.425 y los parámetros de los modelos fueron significativos (p < 0.05), en los cuatro casos. Además, los cuatro modelos seleccionados presentaron normalidad, homogeneidad de varianzas y la inexistencia de colinealidad entre variables. Los modelos seleccionados son estadísticamente confiables para estimar la biomasa por individuo de cada grupo considerado en este estudio, por lo que podrán ser una herramienta útil en la elaboración de planes de manejo para el aprovechamiento de candelilla.
