Pollinator patterns affecting seed set in Baptisia alba.

The flowering structure of a plant may impact the quality of the seed set if the pollinator has a particular pollination pattern (Arista et al. 1999). In this study, we examine how the foraging patterns of the current pollinators impact the reproductive success of Baptisia alba at Shaw Nature Reserve. We combined pollinator observations and pollen load analysis to determine main pollinators. We recorded pollinator foraging patterns. We compared seed sets (n=11 plants) for flowers at the bottom and top of the inflorescence to determine impact of potential geitonogamous pollen deposition by pollinators. Our results show that Bombus are responsible for 89.6% of the total pollen flow in these populations. Bombus consistently forage in a bottom to top pattern on inflorescences like Baptisia alba, which have multiple flowers. Our results indicated no statistical difference (p=.6172) between top and bottom seed sets. Therefore, we conclude that the foraging pattern of the main pollinator Bombus, although most likely increasing geitonogamous pollen deposition in flowers at the top of the inflorescence, are not impacting the reproductive success of B. alba.
