how fruit blossoms are pollinated
...ese hairs are on the thorax of the bee and look remarkably like small feathers. Pollen grains become tangled in these hairs when a bee visits a flower to extract nectar or collect pollen from anthers. As bees fly from flower to flower, pollen rubs off of their body hairs onto the sticky surface of the stigma. Pollination begins when a bee stops to gather food from a flower. Then the sticky pollen gets caught in the small hairs that are on the bee’s body. Still looking for food, the bee travels to another flower. Some of the pollen on the bee’s body falls onto this new blossom. When pollen is transferred from one plant to another of the same species, it becomes possible for the blossom to produce fruit. Weather at blossom time plays a dominant role in pollination. As temperature falls to 28 degrees F., ice formation within the flower tissue can cause injury to fruit finish. At 27 degrees and below, the styles and ovules can be killed, preventing fertilization. Low temperatures can cause the pollen not to germinate a...
