Pyrus Nivalis Flower
Pears are fruits produced and consumed around the world, growing on a tree and harvested in the Northern Hemisphere in late summer into October. The pear tree and shrub are a species of genus ''Pyrus'' , in the family Rosaceae, bearing the pomaceous fruit of the same name. Several species of pears are valued for their edible fruit and juices, while others are cultivated as trees. The tree is medium-sized and native to coastal and mildly temperate regions of Europe, North Africa, and Asia. Pear wood is one of the preferred materials in the manufacture of high-quality woodwind instruments and furniture. About 3,000 known varieties of pears are grown worldwide, which vary in both shape and taste. The fruit is consumed fresh, canned, as juice, or dried. Etymology The word ''pear'' is probably from Germanic ''pera'' as a loanword of Vulgar Latin ''pira'', the plural of ''pirum'', akin to Greek ''apios'' (from Mycenaean ''ápisos''), of Semitic origin (''pirâ''), meaning "frui ...

Pyrus Communis
''Pyrus communis'', the common pear, is a species of pear native plant, native to central and eastern Europe, and western Asia. It is one of the most important fruits of temperate regions, being the species from which most orchard pear cultivars grown in Europe, North America, and Australia have been developed. Two other species of pear, the Nashi pear (''Pyrus pyrifolia'') and the hybrid Chinese white or ya pear (''Pyrus × bretschneideri'', ) are more widely grown in East Asia. Subtaxa The following subspecies are currently accepted: *''Pyrus communis'' subsp. ''caucasica'' – Turkey, Caucasus *''Pyrus communis'' subsp. ''communis'' – Entire range except Caucasus Origin The cultivated Common pear (''P. communis'' subsp. ''communis'') is thought to be descended from two subspecies of wild pears, categorized as Pyrus pyraster, ''P. communis'' subsp.'' pyraster'' (syn. ''P. pyraster'') and ''P. communis'' subsp. ''caucasica'' (syn. ''P. caucasica''), which are interfertile wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perseus Project
The Perseus Project is a digital library project of Tufts University, which assembles digital collections of humanities resources. Version 4.0 is also known as the "Perseus Hopper", and it is hosted by the Department of Classical Studies. The project is mirrored by the Max Planck Society in Berlin, Germany, as well as by the University of Chicago. History The project was founded in 1987 to collect and present materials for the study of ancient Greece. It has published two CD-ROMs and established the Perseus Digital Library on the World Wide Web in 1995. The project has expanded its original scope; current collections cover Greco-Roman classics and the English Renaissance. Other materials, such as the papers of Edwin Bolles and the history of Tufts University, have been moved into the Tufts Digital Library. The editor-in-chief of the project is Gregory R. Crane, the Tufts Winnick Family Chair in Technology and Entrepreneurship. He has held that position since the founding of th ...

Pome
In botany, a pome is a type of fruit produced by flowering plants in the subtribe Malinae of the family Rosaceae. Well-known pomes include the apple, pear, and quince. Etymology The word ''pome'' entered English in the late 14th century, and referred to an apple or an apple-shaped object. It derived from the Old French word for "apple": (12th century; modern French is ), which in turn derived from the Late Latin or Vulgar Latin word "apple", originally the plural of Latin "fruit", later "apple". Morphology A pome is an accessory fruit composed of one or more carpels surrounded by accessory tissue. The accessory tissue is interpreted by some specialists as an extension of the receptacle and is then referred to as "fruit cortex",Esau, K. 1977. ''Anatomy of seed plants''.
