Any of approximately 20 species of deciduous trees, and their fruits, in the genus Pyrus (order Rosales). About half of the species of pear are native to Europe, North Africa, and the Middle East, especially areas around the Mediterranean Sea; the remaining species are native to Asia. Pear culture is documented to have started as early as 1100 BC. Pears are best adapted to temperate climates with warm, dry summers and cold winters. They require winter cold to break the dormant period, but they are injured by temperatures lower than −10°F to −15°F (−23°C to −26°C). Commercial pear production in the United States is concentrated in the interior valleys of California, Oregon, and Washington. See also: Dormancy; Fruit; Fruit, tree; Horticultural crops; Rosales
