Geitonogamy can be due to self-pollination between flowers on the same branch, different flowering branches of the same plant, or different ramets of the same clonal genet. |
Has this method, which is spoken of as geitonogamy, the same influence as crossing with pollen from another plant? |
No differences were noted in pollen germination, pollen tube growth or fertilization between experimental tests of xenogamy and geitonogamy in S. mucugensis. |
Both species use a mixed breeding system, consisting of xenogamy, geitonogamy, and autogamy. |
Protogyny may also reduce geitonogamy if the flowers on an inflorescence develop so that all open flowers are in either male or female phase at any given time. |
Together, the three modes of geitonogamy make a much larger contribution to self-fertilization than autogamy. |
