  2. Self-pollination - Wikipedia

    en.wikipedia.org/wiki/Self-pollination

    Self-pollination is a form of pollination in which pollen arrives at the stigma of a flower (in flowering plants) or at the ovule (in gymnosperms) of the same plant. The term cross-pollination is used for the opposite case, where pollen from one plant moves to a different plant.

  3. Monocotyledon reproduction - Wikipedia

    en.wikipedia.org/wiki/Monocotyledon_reproduction

    Self-compatible (SC) pollination systems are less common than self-incompatibile cross-pollination systems in angiosperms. [11] However, when the probability of cross-pollination is too low it can be advantageous to self-pollinate. Self-pollination is known to be favored in some orchids, rices, and Caulokaempferia coenobialis (Zingiberaceae).

  4. List of pollen sources - Wikipedia

    en.wikipedia.org/wiki/List_of_pollen_sources

    For the plant, the pollinizer, this can be an important mechanism for sexual reproduction, as the pollinator distributes its pollen. Few flowering plants self-pollinate ; some can provide their own pollen (self fertile), but require a pollinator to move the pollen; others are dependent on cross pollination from a genetically different source of ...

  5. Autogamy - Wikipedia

    en.wikipedia.org/wiki/Autogamy

    Self-pollination is an example of autogamy that occurs in flowering plants. Self-pollination occurs when the sperm in the pollen from the stamen of a plant goes to the carpels of that same plant and fertilizes the egg cell present. Self-pollination can either be done completely autogamously or geitonogamously. In the former, the egg and sperm ...

  6. Pollination - Wikipedia

    en.wikipedia.org/wiki/Pollination

    Self-pollination may include autogamy, where pollen is transferred from anther (male part) to the stigma (female part) of the same flower; or geitonogamy, when pollen is transferred from anther of a flower to stigma of another flower on the same plant. [47] Plants adapted to self-fertilize often have similar stamen and carpel lengths.

  7. Pollinator - Wikipedia

    en.wikipedia.org/wiki/Pollinator

    Plants fall into pollination syndromes that reflect the type of pollinator being attracted. These are characteristics such as: overall flower size, the depth and width of the corolla, the color (including patterns called nectar guides that are visible only in ultraviolet light), the scent, amount of nectar, composition of nectar, etc. [2] For example, birds visit red flowers with long, narrow ...

  8. Homogamy (biology) - Wikipedia

    en.wikipedia.org/wiki/Homogamy_(biology)

    Self-pollination is promoted by homogamy. Homogamy is when the anthers and the stigma of a flower are being matured at the same time. [5] The action of self-pollination guides the plant to homozygosity, causing a specific gene to be received from each of the parents leading to the possession of two exact formats of that gene. [6]

  9. Cleistogamy - Wikipedia

    en.wikipedia.org/wiki/Cleistogamy

    Cleistogamy is a type of automatic self-pollination of certain plants that can propagate by using non-opening, self-pollinating flowers. Especially well known in peanuts, peas, and pansies, this behavior is most widespread in the grass family. However, the largest genus of cleistogamous plants is Viola. [1]
