2 Pollen applied once, immediately after emasculation. 3 Treated same as treatment 2, then poHen was applied again on the following day. 4 Treated same as treatment 3, then pollen was applied again on the 3d day. 5 Treated Same as treatment 4, then pollen was applied again on the 4th day. The results showed that for the largest number of berries with the most drupelets, each flower should be repeatedly visited by bees for at least 4 days.
Honey bees are the best pollinating agents of raspberries.
Because honey bees and raspberries are mutually benefited, these insects should be given major consideration as pollinators of raspberries. He recommended one colony for each 2 acres. The evidence is plain that the plant requires or at least is greatly benefited by such pollination. Where the crop is grown commercially with its vast numbers of blossoms calling for insect transfer of pollen from anthers to stigmas, whether on the same flower, flowers of the same plant, or between plants, bees should be supplied to the plantings. The grower is interested in the largest possible berries as well as maximum production.
