Branch of a Rainier cherry tree. Rainier (/ r eɪ ˈ n ɪər / ray-NEER) is a cultivar of cherry. It was developed in 1952 at Washington State University by Harold Fogle, and named after Mount Rainier. It is a cross between the Bing and Van cultivars. [1] Rainiers are considered a premium type of cherry. They are sweet with a thin skin and ...
The cross was made in 1936, selected in 1942, and introduced in 1944, with the resulting tree named in honor of horticulturalist J. R. Van Haarlen. [3] The Van cherry was one of the parent varieties of the Lapins cherry [4] and the Rainier cherry.
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 ...
Trees that are cross-pollinated or pollinated via an insect pollinator produce more fruit than trees with flowers that just self-pollinate. [1] In fruit trees, bees are an essential part of the pollination process for the formation of fruit. [2] Pollination of fruit trees around the world has been highly studied for hundreds of years.

Xenogamy (Greek xenos=stranger, gamos=marriage) is the transfer of pollen grains from the anther to the stigma of a different plant. This is the only type of cross pollination which during pollination brings genetically different types of pollen grains to the stigma.
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 ...
Pollination by a specialist can result in high flowering synchrony, as asynchronous flowering can result in erratic attraction of a specialist to a site. [19] Showy floral displays tend to attract pollinators, [ 20 ] [ 21 ] and synchronous flowering can attract more pollinators to a population.
Sweet cherry trees were initially taken to the United States with the colonists in 1629. [3] In 1847, Henderson Lewelling took 700 fruit trees of Napoleon Bigarreau from Iowa to Oregon’s Willamette Valley to start a cherry orchard. Seth Lewelling joined his brother Henderson in 1850, he renamed the tree 'Royal Ann'. Seth later developed the ...
