Geitonogamy

When pollens of a flower pollinate any other flower present on the same plant, it is said to be geitonogamy

Geitonogamy (meaning: marriage between neighbours) is the transfer of pollen grains from the anther of one flower to the stigma of another flower borne on the same plant.

Key Characteristics

• Functionally → similar to cross-pollination, as it involves a pollinating agent (e.g., bees, wind).
• Genetically → similar to autogamy (self-pollination), because pollen grains come from the same plant and therefore carry the same genetic material.
• It is of ecological significance only - it does not bring about genetic variation.

• Geitonogamy is the transfer of pollen from anther to the stigma of another flower on the same plant.
• It is functionally cross-pollination because it involves a pollinating agent.
• It is genetically similar to self-pollination (autogamy) since pollen comes from the same plant.
• Thus, it shows features of both self and cross-pollination.
