Pollination: Definition, Types, and Agents
Pollination:Definition
Pollen grains are transmitted from the Anther to the Stigma during pollination. When pollen grains land on ovule, it is known as Direct pollination e,g Gymnosperms, and some primitive Angiosperms. When pollen grains land on Stigma and form a pollen tube it is known as Indirect pollination e,g Angiosperms. Pollination’s function in fruit and seed production has been recognised since ancient times. The Arab and Assyrian kings used to perform a special religious ceremony in which the female inflorescence of the date palm was touched by the male inflorescence to ensure good fruiting. However, Thomas Millington, towards the end of the 17th century, provided the scientific underpinning for this method.
