Self-pollination is where the pollen is transferred to the stigmas of the same flower or the stigma of another flower on the same plant. Self-pollination is obviously more reliable, particularly if the nearest plant is not very close.


self-pollination
The transfer of pollen from anther to stigma in the same flower or to another flower of the same plant, leading to self-fertilization.

Self-pollination. Pollen of one plant is transferred to the female part of the same plant or another plant with the same genetic makeup.

Self-pollination - The process by which the male gametes of a plant fertilize the eggs of the same plant.
Sporangium - The part of a plant where spores are produced.
Spore - Haploid cell from which a gametophyte is produced.

Self-pollination
See autogamy.

Autogamy
Transfer of pollen (pollination) from the anther of a flower to the stigma of the same flower or sometimes to that of a genetically identical flower (as of the same plant or clone).

self-pollination Transfer of pollen from stamen to stigma within the same plant.
self-pollinating plant A plant that has its own pollen fall on its own stigma.

Pollination can be cross-pollination with a pollinator and an external pollenizer, self-pollenization with a pollinator, or self-pollination without any pollinator: ...

Mendel's experimental organism was a common garden pea (Pisum sativum), which has a flower that lends itself to self-pollination. The male parts of the flower are termed the anthers. They produce pollen, which contains the male gametes (sperm).

Switching from Cross-Pollination to Self-Pollination
A substantial minority of angiosperms have abandoned cross-pollination for self-pollination. For example, while its wild relatives continue to be cross-pollinated, the domestic tomato is not.

Seed produced through self-pollination ("selfed" seed) is often inferior in growth, survival, and fecundity to seed produced through outcross pollination ("outcrossed" seed).

/OUT-cross/ (1) mating in which the male and female gametes are derived from different individuals; used in opposition to self-fertilization; (2) the pollination of a stigma with pollen from another plant (used in opposition to self-pollination); ...

to the stigma of the same flower or sometimes to that of a genetically identical flower (as of the same plant or clone). Ability of many plant species to naturally and successfully fertilize within one individual.
Also called self-pollination.

It is a plant model system of choice because of the additional advantages of short generation time (about five weeks), high seed production (up to 40,000 seeds per plant) and natural self-pollination ...
