(redirected from geitonogamous)
Also found in: Dictionary, Wikipedia.


Pollination and fertilization of one flower by another on the same plant.



cross-pollination within the same plant as a result of the transfer of pollen by insects or by the wind from one flower to another. Geitonogamy is known to occur, for instance, among carrots during their flowering when flies crawl over the entire raceme and transfer the pollen picked up on one flower to the stigma of the pistil of another. Occasionally certain plants (toadflax, for example) do not produce seeds in geitonogamy.

Considering the many simultaneous flowers produced by these species, the amount of nectar exuded, the hummingbird behavior, and the existence of SC, hummingbird visits likely favor geitonogamous rather than xenogamous pollen transfer.
