The interactions between robbers and legitimate pollinators affects on plant reproduction

为了研究抢夺花蜜是否影响双歧堇（Corydalis ambigua）群体的繁殖和交配模式，本文基于微卫星基因分型研究了抢夺花蜜比例、种子产量和近交程度之间的关系。5个居群中有3个居群的断花比例较高，且存在花粉限制（即开放授粉后的种子产量低于异花授粉）。此外，在断花比例较高的群体中，近交系数显著。这些结果表明，强盗和合法传粉者之间的相互作用影响了植物繁殖的数量和质量。

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.
