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.
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).
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 Asexual propagation (e.g. runners from strawberry plants) where the new plant is genetically identical to its parent
Self-pollination occurs when pollen from one flower pollinates the same flower or other flowers of the same individual. [45] It is thought to have evolved under conditions when pollinators were not reliable vectors for pollen transport, and is most often seen in short-lived annual species and plants that colonize new locations.

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]
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
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 ...
A pollinator garden is a type of garden designed with the intent of growing specific nectar and pollen-producing plants, in a way that attracts pollinating insects known as pollinators. [1] Pollinators aid in the production of one out of every three bites of food consumed by humans, and pollinator gardens are a way to offer support for these ...
