oleifera is a geitonogamous and xenogamous diploid species (2n = 28; n = 14 chromosomes) whose gene pool and genetic base are expected to be wide with higher productivity [11, 12, 13, 14].
Consequences of floral complexity for bumblebee-mediated geitonogamous self-pollination in Salvia nipponica Miq.
This species has been reported as an inbreeder favoring geitonogamous pollination (87% fruit set) compared with 53.
Although flowers with a wide availability of resources are heavily visited, many self-compatible species have a high degree of inbreeding caused by geitonogamous pollination, apomixis, and also automatic self-pollination (BAWA, 1979).
From the orthogonal contrasts, flowers of autogamous racemes produced more seedless pods than geitonogamous flowers (G = 5.
Nonetheless, individual pollen loads are usually below levels that provide higher probability of retention, and commonly observed geitonogamous pollinations also appear to conflict with expected strong selection on moths to provide pollinations that give high retention probability.
For clonal species with SI systems, geitonogamous pollination within genetically uniform patches causes a reduction in MA that hampers sexual reproduction (Thien et al.
nectar production is an adaptation to decrease geitonogamous inbreeding
Comparing intact and emasculated flowers open on the same plant on the same day will underestimate autogamy, because emasculation of one flower potentially reduces the geitonogamous pollen received by the other.
This may result in a limit to geitonogamous pollen transfers and long distance pollen flow (Dressler 1981).
In the Faroes Islands, Hagerup (1951) indicated that species with large inflorescences tended to be geitonogamous.
These observations suggest that butterflies and small bees produced geitonogamous pollinations less often than large bees, and that outcross pollination thus occurred more often during the MD period.
