| Research Abstract |
To test whether nectar robbing affects plant reproduction and mating patterns in the populations of Corydalis ambigua, I investigated the relationships between proportion of robbed flowers, seed production, and the degree of inbreeding based on microsatellite genotyping. Three of five population involved higher proportion of robbed flowers and showed pollen limitation (i.e., seed production after open pollination was lower than cross pollination). In addition, significant inbreeding coefficient was found at the populations with higher proportion of robbed flowers. These results suggest that the interactions between robbers and legitimate pollinators affect both the quantity and quality of plant reproduction.
