Firstly, pollination is the transfer of pollen from the anther (male organ of the flower) to the stigma (female organ of the flower) of the same or different flower. Secondly, fertilization occurs once the pollen grain reaches the stigma, it produces a pollen tube, which grows down through the style to the ovary.
Pollination takes place immediately before the anthesis. Anthers elevate by elongating the stamen filaments, and untimately they go out the spikelet during anthesis. When anthers touch stigma, some pollen are left on the stigma. The stigma can receive pollen also during the flowering, when the spikelet opens.
