In hermaphrodites, self-incompatibility
produces differences in fertilization success that are similar in magnitude to among-species crosses, which could result in fairly strong selection pressures against self-fertilization when non-self eggs are available.
Pollen tube growth was not interrupted in the cross-pollination treatment, in contrast to self-pollinated flowers, where pollen tube growth stopped in the stigma or in the style, identifying possible sites of pre-zygotic self-incompatibility
Macrophylogenetic analyses of the gain and loss of self-incompatibility
in the Asteraceae.
Some studies have, however, found no differences in outcrossing rate in populations of different size or density, particularly in species with a strong self-incompatibility
mechanism (Cascante et al.
Self-fertilization in passion fruit is hampered due to self-incompatibility
in the threatened shrub Oleria adenocarpa (Asteraceae).

In flowering plants (also called angiosperms), an intraspecific reproductive mechanism, self-incompatibility
(SI), has so far been widely known.
The gametophytic self-incompatibility

) in three species, D.
