Examples

  • However, wind and self-pollination are more widespread among arctic flowering plants, so any mismatch between pollinator activity and flowering phenology is likely to be of greater significance to any plants immigrating to the Arctic as temperatures increase.

  • Clarity requires that the term "self-pollination" be restricted to those plants that accomplish pollination without an external pollinator (example: the stamens actually grow into contact with the pistil to transfer the pollen).

    Pollination

  • This is sometimes referred to as self-pollination, but this is not synonymous with autogamy.

    Pollination

  • Cleistogamy:. is self-pollination that occurs before the flower opens.

    Pollination

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

    Pollination

  • Other plants have chemical or physical barriers to self-pollination and need to be cross-pollinated: with these self-infertile plants, not only pollinators must be considered but pollenizers as well.

    Pollination

  • (But self-pollination is still sexual reproduction which results in different combinations of genes and therefore allows evolutionary change, as vegetative cloning does not.)

    Pollination ecology of desert plants

  • Outcrossing (pollination by pollen from another plant) is evolutionarily advantageous because the offspring are more variable than those from self-pollination.

    Pollination ecology of desert plants

  • Vanilla flowers are hermaphroditic: they carry both male and female organs; however, to avoid self-pollination, a membrane separates those organs.

  • I suspect it would be favored in situations where pollen from diverse sources is available, but the danger of self-pollination or pollination from very-near relatives is also high.
