Triangulating from the cairns…
To date there are few studies that have carefully studied the impact that varying pollen quantity and proportion of heterospecific pollen has on reproductive rate of a flowering plants. My project aimed to assess the relationship between pollen quantity and composition on the subalpine larkspur, Delphinium barbeyi, by conducting hand-pollination treatments that varied in pollen composition (proportion of heterospecific pollen) and quantity. Across 6 different sites, a total of 96 racemes of D. barbeyi were subjected to different treatments consisting of D. barbeyi and Helianthella quinquenervis pollen in different proportions. A significant relationship was found between seed set and pollen quantity, when looking at a subsample of the data collected.
