geitonogamy in British English (ˌɡaɪtəˈnɒɡəmɪ) noun botany the transfer of pollen to a stigma of a different flower on the same plant Word origin C19: from Greek geitōn neighbour + -gamyExamples of 'geitonogamy' in a sentencegeitonogamy The fruit set largely occurs through geitonogamy and xenogamy.These forms of flowers with strong protandry prevent autonomous selfing but not geitonogamy.Both situations increase geitonogamy rates, raising significantly fruit set and seed yield.Thrips use this plant as breeding and feeding sites; they largely contribute to geitonogamy.The fruit set was between 79 and 88% through the manual self-pollination, and through the geitonogamy, and the xenogamy.Treatments of controlled pollinations, self-pollination, geitonogamy, cross-pollination, natural pollination and growth to pollen tube were sampled.Interestingly, individual plants exhibited broad variation in selfing ability with six out of 14 individuals producing no seed after geitonogamy.For the self-pollination, apomixis, geitonogamy and xenogamy experiments, buds were protected, emasculated, and pollinated when necessary.Moreover, differential fertility and enantiostyly may diminish the effects of self-compatibility by partially reducing the contribution of geitonogamy to selfing.The plants produced fruits with both geitonogamy and xenogamy, although insect pollination significantly increased the number and quality of fruits. |
