[[Pollination]] of [[fruit trees]] is required to produce seeds with surrounding fruit. It is the process of moving pollen from the [[anther]] to the [[Stigma (botany)|stigma]], either in the same flower or in another flower. Some tree species, including many fruit trees, do not produce fruit from [[self-pollination]], so [[pollinizer]] trees are planted in orchards.

The pollination process requires a carrier for the pollen, which can be animal, wind, or human intervention (by [[hand-pollination]] or by using a pollen sprayer). [[Cross pollination]] produces seeds with a different [[genetics|genetic]] makeup from the parent plants; such seeds may be created deliberately as part of a [[selective breeding]] program for fruit trees with desired attributes. Trees that are cross-pollinated or pollinated via an insect pollinator produce more fruit than trees with flowers that just self-pollinate.<ref name="Abrol">{{cite book|last1=Abrol|first1=Dharam|title=Pollination Biology, Vol. 1|date=2015|publisher=Springer International Publishing|location=Switzerland|isbn=978-3-319-21084-1}}</ref> In fruit trees, bees are an essential part of the pollination process for the formation of fruit.<ref name="McGregor">{{cite journal|last1=McGregor|first1=Samuel|title=Insect pollination of cultivated crop plants|journal=Agricultural Research Service, US Department of Agriculture|date=1976|issue=496}}</ref>

Pollination of fruit trees around the world has been highly studied for hundreds of years.<ref name="Abrol" /> Much is known about fruit tree pollination in [[temperate climate]]s, but much less is known about fruit tree pollination in [[tropical climate]]s.<ref name="Abrol" /> Fruits from temperate climates include [[apples]], [[pear]]s, [[plums]], [[peach]]es, [[Cherry|cherries]], [[berries]], [[grapes]], and [[nut (fruit)|nuts]] which are considered dry fruits.<ref name="Abrol" /> Fruits from tropical climates include [[bananas]], [[pineapples]], [[papayas]], [[passion fruit]], [[avocado]], [[mango]], and members of the genus ''[[Citrus]]''.
