Transfer of pollen grains from anther to stigma of a pistil is known as pollination. Animals such as insects, birds, and bats, as well as water, wind, and even plants themselves, when self-pollination happens within a closed bloom, are pollinating agents. Within a species, pollination is common.
Pollination is studied in several fields, including botany, horticulture, entomology, and ecology. The interaction between the flower and the pollen vector in the pollination process.
Types of pollination
Depending upon the source of pollen, pollination can be divided into three types.
1. Autogamy
In this pollination Transfer of pollen grains from the anther to the stigma of the same flower occurs.
2. Geitonogamy
Transfer of pollen grains from the anther to the stigma of another flower of the same plant. Although geitonogamy is functionally cross pollination
3. Xenogamy
Transfer of pollen grains from anther to the stigma of a different plant.
This is only type of pollination brings genetically different types of pollen grains to the stigma.
