Resumen:
Prosopis L. pods have been proposed as a source of gum (galactomannans), with potential
applications as a thickening agent in the food industry. The objective of this work was to
compare, under field conditions, the production and mortality of reproductive structures in
two sympatric shrub species of Prosopis: P. alpataco Phillipi and P. denudans Bentham. Our
results indicate that fruit production in Prosopis denudans and P. alpataco is very low and
erratic in non-irrigated lands. Although large quantities of flowers (15,00025,000 flowers*
0.40m_2) can be found in one flowering season, 7080% are shed before they reach anthesis
and 2028% are aborted between anthesis and fruit set. We conclude that the utilization of
native populations of Prosopis denudans and P. alpataco for fruit production in Patagonian
steppe, could not guarantee a consistent supply for the food industry.
