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.
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 ...
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 ...
Cucumbers may also be pollinated via bumblebees and several other bee species. Most cucumbers that require pollination are self-incompatible, thus requiring the pollen of another plant in order to form seeds and fruit. [10] Some self-compatible cultivars exist that are related to the 'Lemon cucumber' cultivar. [10]
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]

Geitonogamy is when pollen is exported using a vector (pollinator or wind) out of one flower but only to another flower on the same plant. It is a form of self-fertilization. In flowering plants, pollen is transferred from a flower to another flower on the same plant, and in animal pollinated systems this is accomplished by a pollinator
One particularly interesting case is the Prunus SI systems, which functions through self-recognition [15] (the cytotoxic activity of the S-RNAses is inhibited by default and selectively activated by the pollen partner SFB upon self-pollination), [where "SFB" is a term that stands "for S-haplotype-specific F-box protein", as explained ...
