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).

Relative to self-pollination, outcross pollination results in greater proportion of flowers setting fruit, and greater proportion of ovules yielding seeds per fruit.

It is clear though that the number of seeds produced by the self-pollination treatments were consistently lower than those from the cross pollination treatments and reproductive success would be better estimated by taking into account not only fruit and seed sets, but seed germination as well.
