Flowers within a plant were assigned to the following treatments: (1) agamospermy (flowers had their stigma removed at the beginning of anthesis); (2) autonomous self-pollination (un-manipulated bagged flowers); (3) hand self-pollination (flowers hand-pollinated with their own pollen); (4) hand cross-pollination (previously emasculated flowers hand-pollinated with pollen from another plant), and (5) natural pollination (un-manipulated and randomly selected flowers exposed to pollinators in the field).
Ten flowers in pre-anthesis of female plants were emasculated marked and bagged to verify the occurrence of agamospermy in this species.
We performed the following five treatments: self-pollination, spontaneous self-pollination, geitonogamy, xenogamy and agamospermy.
Recent studies showed that the reproductive system of this species is self-compatible; it does not produce fruits via either autogamy or agamospermy, but requires, obligatorily, pollen vectors due to buzz pollination syndrome (Andrade, 2004).
Although these offspring are often outcrossed seeds, they may also be a result of agamospermy (Crawley 1997) or, in the case of aquatic plants, widely dispersing clonal fragments (Room 1990, Philbrick and Les 1996).
