Examples

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

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

    Pollination

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

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

    Pollination

  • 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

  • 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.

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

    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.)
