- the transfer of pollen from the anther to the stigma of the same flower, another flower on the same plant, or the flower of a plant of the same clone.

He may then, as he pushes down after nectar, leave some pollen upon the pistil, thus assisting in self-pollination.
First the anthers must be carefully removed from the bud of the flower so as to eliminate all possibility of self-pollination.
Self-pollination in the case of the short-styled form, for example, is not excluded.Darwin and Modern Science

- the transfer of pollen from the anthers to the stigma of the same flower or of another flower on the same plantCompare cross-pollination
- The transfer of pollen from a male reproductive structure (an anther or male cone) to a female reproductive structure (a stigma or female cone) of the same plant or of the same flower. Self-pollination tends to decrease the genetic diversity (increase the number of homozygous individuals) in a population, and is much less common than cross-fertilization. Many species of plants have evolved mechanisms to promote cross-pollination and avoid self-pollination, though certain plants, such as the pea, regularly self-pollinate. Compare cross-pollination.
