self-pollination

the transfer of pollen from the stamen of a flower either to the stigma of the same flower or to another flower on the same plant. Since self-pollination leads to self-fertilization which is a form of inbreeding, many plants have developed mechanisms to prevent its occurrence. For example, plants can be DIOECIOUS, show SELF-INCOMPATIBILITY, and have differential maturation times of male and female floral organs on the same plants (for example, see ARUM LILY). Compare CROSS-POLLINATION.

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).

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.

Considering the discrepancy of this result with those of other studies and the fact that in evolutionary terms, self-pollination does not appear as a survival strategy, it can be hypothesized that this result may be associated with a deficiency in the attraction and the abundance or dispersal of pollinators.

However, production of achenes alone is not a good measure of reproductive success of Asteraceae, especially when flowers are self-pollinated, because a high percentage of achenes produced by self-pollination do not contain an embryo (Nielsen et al.
