Pollination- Self and Cross – Pollination – Notes

Pollination and Major Agent

Pollination is a process through which pollen shed from the anther is transferred to the stigma of the pistil.

When pollination takes place within the same flower or between flowers of the same plant, it is known as self – pollination.

In autogamy, pollen is transferred from the anther of a flower to the stigma of the same flower.

In geitonomy, the second type of self – pollination, the pollen is transferred from the anther to one flower to the stigma of another flower on the same plant.

Cross – pollination or xenogamy involves the transfer of pollen grain from a flower of one plant to the stigma of a flower of another plant.

Pollinating agents are either abiotic or biotic.
