  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.

    Plant species where normal mode of seed set is through a high degree of cross-pollination have characteristic reproductive features and population structure. Existence of self-sterility, [1] self-incompatibility, imperfect flowers, and mechanical obstructions make the plant dependent upon foreign pollen for normal seed set. Each plant receives ...

    en.wikipedia.org/wiki/Selfing_Syndrome

    Selfing syndrome refers to plants that are autogamous and display a complex of characteristics associated with self-pollination. [1] The term was first coined by Adrien Sicard and Michael Lenhard in 2011, but was first described in detail by Charles Darwin in his book “The Effects of Cross and Self Fertilisation in the Vegetable Kingdom” (1876), making note that the flowers of self ...

    Cleistogamy: is self-pollination that occurs before the flower opens. The pollen is released from the anther within the flower or the pollen on the anther grows a tube down the style to the ovules. It is a type of sexual breeding, in contrast to asexual systems such as apomixis.

    However, as opposed to 'complete' or 'absolute' SI, in CSI, self-pollination without the presence of competing cross pollen, results in successive fertilization and seed set; [45] in this way, reproduction is assured, even in the absence of cross-pollination. CSI acts, at least in some species, at the stage of pollen tube elongation, and leads ...

  7. Cleistogamy - Wikipedia

    en.wikipedia.org/wiki/Cleistogamy

    Chasmogamous (a) and cleistogamous (b) flowers of Viola pubescens. Arrows point to structure. 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.
