  2. Pollination - Wikipedia

    en.wikipedia.org/wiki/Pollination

    Plants adapted for cross-pollination have several mechanisms to prevent self-pollination; the reproductive organs may be arranged in such a way that self-fertilisation is unlikely, or the stamens and carpels may mature at different times. [8] Self-pollination occurs when pollen from one flower pollinates the same flower or other flowers of the ...

    en.wikipedia.org/wiki/Selection_methods_in_plant...

    Plant breeders use different methods depending on the mode of reproduction of crops, which include: Self-fertilization, where pollen from a plant will fertilise reproductive cells or ovules of the same plant; Cross-pollination, where pollen from one plant can only fertilize a different plant

    Entomophily is a form of plant pollination whereby pollen is distributed by insects, particularly bees, Lepidoptera (butterflies and moths), flies and beetles. Honey bees pollinate many plant species that are not native to their natural habitat but are often inefficient pollinators of such plants; if they are visiting ten different species of ...

    en.wikipedia.org/wiki/Pollinator-mediated_selection

    This leads to shifts in pollination syndromes and to some genera having a high diversity of pollination syndromes among species, suggesting that pollinators are a primary selective force driving diversity and speciation. [5] [6] Ophrys apifera is an orchid species that has a highly evolved plant-pollinator relationship. This specific species ...

  6. 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.

  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 ...

    This period is different for every guy and can last anywhere from minutes to a full day. However, there are ways to shorten this phase, she explains. The best way to decrease refractory time is by ...

  9. Reproduction - Wikipedia

    en.wikipedia.org/wiki/Reproduction

    Allogamy is the fertilization of flowers through cross-pollination, this occurs when a flower's ovum is fertilized by spermatozoa from the pollen of a different plant's flower. [15] [16] Pollen may be transferred through pollen vectors or abiotic carriers such as wind. Fertilization begins when the pollen is brought to a female gamete through ...
