self-pollination(redirected from Self pollination)
Also found in: Dictionary, Thesaurus, Encyclopedia.
self-pollinationthe 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.
