In epiphytic plants, autogamy has been interpreted as a mechanism to compensate for their apparent reduced capacity to attract pollinators due to their low floral display and highly aggregated spatial distribution in the forest canopy (Bush & Beach, 1995).
While 40% of the plants tested for autogamy produced at least one fruit and 31 % showed evidence of self-compatibility, total fruits produced in either set of crosses was low.
Reproductive assurance through unusual autogamy in the absence of pollinators in Passiflora edulis (passion fruit).
are the major pollinators of the congeners although both show a minor degree of autogamy (Haddock and Chaplin, 1982).
This evidence becomes stronger because the manual self-pollination presented the second best rate of initial fruit set, implying the existence of a strong autogamy in this species.
Synchronous stigma receptivity, anther dehiscence, relative length and close proximity of anthers and stigma predispose makes this species suitable for autogamy (Kaul et al.
Fifty mature buds, five each from ten inflorescences on five trees were bagged a day before anthesis without manual self pollination to know whether fruit set occurs through autogamy.
Spellenberg (1975) studied populations of some subspecies in the western United States and proposed that autogamy and hybridization were common means that accounted for much of the morphological variation, and thus, the taxonomic difficulty encountered in the complex.
