Ten self-fertile commercial sunßowers cultivars were evaluated for seed set with and without exposure to bees. In the Þrst planting, the number of foraging honey bees was smaller than in the second, and seed set for most cultivars did not differ between those bagged to exclude bees and ones that were open pollinated. In the second planting, however, a majority of cultivars had significantly gre...
