Resumen
Fruits formed after different pollination regimes (flowers hand pollinated, unpollinated, and open pollinated) and the seeds obtained were characterized in the wild chilli pepper Capsicum flexuosum Sendtn. Pollen tube development in vivo and ovary growth were also analyzed. Seedless fruits and empty seeds were abundant among the fruits from hand pollinated and open pollinated flowers, while no more than one seed with embryo was found in a low percentage of fruits from such pollination treatments. Parthenocarpic fruits were formed from unpollinated flowers. Pollen tube growth was arrested in the upper third of the style for almost all pollen tubes except for a single one that may continue elongating occasionally. The ovary size increased continuously after pollination, even without fertilization. The sum of the evidence registered may help to explain the low number of seeds with embryo harvested, the abundance of seedless fruits formed from pollinated flowers (possibly parthenocarpic), and the high rate of parthenocarpic fruits formed from unpollinated flowers.
