Pyrus (genus)

Genus containing around 30 species of medium sized trees native to coastal and mildly temperate regions of the Old World, from western Europe, north Africa, and Asia. It is one of the most important fruit trees of the world and is cultivated in all temperate-zone countries of both hemispheres. Valued for fleshy edible fruit (a pome), typically having a broad base and tapering or constricted towards the stalk, and having sweet taste, soft texture, and distinguished by the presence of hard cells in the flesh, the so-called grit, or stone cells. Pear trees are relatively long-lived (50 to 75 years), may reach considerable size unless carefully trained and pruned, and are valued for timber.

Pyrus communis (species)
Definición
Species of medium sized, fruit-bearing tree that is probably of European origin, and has been cultivated since long before the Christian era. Thousands of varieties have been bred and named since ancient times in Europe alone. It is propagated by budding or grafting onto a rootstock. In Europe the main rootstock used is quince, which produces a dwarfed tree that fruits at an earlier age than most of the trees on pear rootstocks. The common pear was introduced into the New World by British and other Europeans as soon as the colonies were established. Also at an early date, Spanish missionaries carried the fruit to Mexico and California.
