Geitonogamy (from Greek geiton (γείτων) = neighbor + gamein (γαμεῖν) = to marry) is a type of self-pollination. Geitonogamous pollination is sometimes distinguished from the fertilizations that can result from it, geitonogamy. If a plant is self-incompatible, geitonogamy can reduce seed production. Geitonogamy is when pollen is exported using a vector (pollinator or wind) out of one flower but … Webgeitonogamous pollination, self-fertilization may occur that would decrease ﬁtness, depending on the level of inbreeding depression and pollen discounting (loss of pollen …

WebThis is because geitonogamous pollination by workers was common later in the season, which resulted in a high abortion rate of self-pollinated seeds, that is, qualitative pollen limitation.
