self-pollination
selfing

This is to the advantage of the fig, since it prevents self-pollination.

Cleistogamous - self-pollination of a flower that does not open.

Self-pollination can be an advantage when the number of flowers are small or widely spaced.

Lots of Terran species have evolved ways to avoid self-pollination.

Other plants have chemical or physical barriers to self-pollination.

The flowers are hermaphroditic and have a mechanism to avoid self-pollination.

Some plants use the control of pollen germination as a way to prevent this self-pollination.

The genus may have undergone self-pollination, although it is also possible that insects were involved in the process.

But because such inbreeding can be harmful, many plants have evolved mechanisms to avoid self-pollination.

Although U. thomasii is protandrous, levels of self-pollination remain high.

Geitonogamous self-pollination must therefore occur more often in this species than cross-pollination.

Self-pollination is impossible, and plants are cross-pollinated by insects.

Inbreeding in plants also occurs naturally in the form of self-pollination.

Self-pollination and pollination by insects clearly also play major roles in seed production."

But the more ramets the larger the share of the pollen is lost depending on ineffective self-pollination.

Inbreeding besides self-pollination can also occur, most likely the result of mating between closely related plants.

It is the only species of the genus Ophrys which preferentially practice the self-pollination.

Plants do, in many species, have the back-up option of self-pollination, if they are not self-incompatible.

Because the styles project beyond the anthers, however, self-pollination in nature is probably less frequent than outcrossing.

Self-pollination limits the variety of progeny and may depress plant vigor.

Self-pollination is often avoided by means of protandry.

To prevent unwanted self-pollination of the mother plant, carefully remove its anthers beforehand.

Geraniaceae are normally pollinated by insects, but self-pollination is not uncommon.

Maca reproduces mainly through self-pollination and is an autogamous species.

Dichogamy: Pollen and stigma of the flower mature at different times to avoid self-pollination.
