| description | The aim of this work was to analyze the sprouting strategies of open-pollinated families of Prosopis alba Grisebach in Argentina. In a progeny trial located in the province of Santiago del Estero, 88 families of interest were selected and classified into 16 groups according to the geographical location or climatic behavior of their origin sites. Each individual was characterized according to 16 phenological observations between August 21 and October 8 in 2016. From these measurements sprouting start date and sprouting percentage of each geographical and climatic origin were established. The sprouting strategies were evaluated through the design of a sprouting index for each geographical and climatic origin, through the modeling of the sprouting percentage as a function of time, and the analysis of the mean sprouting rate by geographicaland climatic origins. Results show four sprouting strategies that arise from the combination of three sprouting groups and two sprouting speed groups, the climatic variables of mean annual temperature and temperature of the coldest month being the ones that differentiate these groups. |

El objetivo del trabajo fue analizar las estrategias de brotación de familias de polinización abierta de Prosopis alba Grisebach en Argentina. Se seleccionaron 88 familias de interés en un ensayo de progenies ubicado en la provincia de Santiago del Estero que fueron clasificadas 16 orígenes geográficoclimáticos (OGC) contrastantes. Se realizaron 16 observaciones fenológicas en los individuos marcados entre el 21 de agosto y el 8 de octubre del 2016; se estableció el momento de inicio de brotación y el porcentaje de brotación en cada fecha. Las estrategias de brotación fueron evaluadas a través de la construcción de un índice de brotación para cada origen geográfico-climático, el modelado del porcentaje de brotación en función del tiempo, y el análisis de las velocidades medias de crecimiento de los brotes por origen geográficoclimático. Se evidencia que existen cuatro estrategias de brotación que surgen de la combinación de tres grupos de brotación y dos grupos de velocidad de brotación, siendo las variables climáticas de temperatura media anual y temperatura del mes más frío las que diferencian estos grupos.
