dc.description.abstract
Based on the hypothesis that both plant size and local conspecific density influence allocation to female/male functions, we explored the relationship between plant height, local conspecific density, sexual expression, and fruit production in the andromonoecious shrub Caesalpinia gilliesii. We quantified the total number of perfect and staminate flowers, the pollen received and fruits produced per plant in two populations, and estimated phenotypic gender and fruit set. Local density failed to explain phenotypic gender, nevertheless, plant height and fruit set increased with local density in one population where, in addition, the slopes for the size-dependent sex allocation curve were steeper. As observed for other plant species, this suggests that between population differences in resource availability is the main underlying factor for the observed population differences in the size-dependent allocation pattern to flowers and fruits. On the other hand, the number of staminate and perfect flowers per plant increased with plant height and the fastest increase of staminate flowers resulted in a male-biased size-dependent sex allocation strategy in both populations. Since pollination intensity was not correlated with plant height in any population, the observed allocation strategy cannot be attributed to differences in pollen availability between different sized individuals, but to differences in plant size. Finally, because fruit set and total fruit number increased with plant height in one population, the obtained results provide further evidence that animal-pollinated, andromonoecious species may exhibit a male-biased size-dependent sex allocation strategy, which may favor female fecundity.
