Sprouting strategies analysis of open-pollinated families of Prosopis alba Grisebach in Argentina

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.
