Leaf Miner
A leaf miner is any one of numerous species of insects in which the larval stage lives in, and eats, the leaf tissue of plants. The vast majority of leaf-mining insects are moths ( Lepidoptera), sawflies (Symphyta, the mother clade of wasps), and flies ( Diptera). Some beetles also exhibit this behavior. Like woodboring beetles, leaf miners are protected from many predators and plant defenses by feeding within the tissues of the leaves, selectively eating only the layers that have the least amount of cellulose. When attacking ''Quercus robur'' (English oak), they also selectively feed on tissues containing lower levels of tannin, a deterrent chemical produced in great abundance by the tree. The pattern of the feeding tunnel and the layer of the leaf being mined is often diagnostic of the insect responsible, sometimes even to species level. The mine often contains frass, or droppings, and the pattern of frass deposition, mine shape, and host plant identity are useful to de ...

Pyrus Communis
''Pyrus communis'', the common pear, is a species of pear 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 ''P. communis'' subsp.'' pyraster'' (syn. ''P. pyraster'') and ''P. communis'' subsp. ''caucasica'' (syn. ''P. caucasica''), which are interfertile with domesticated pears. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyrus
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 ...

Prunus Serotina
''Prunus serotina'', commonly called black cherry,World Economic Plants: A Standard Reference, Second Edition'. CRC Press; 19 April 2016. . p. 833–. wild black cherry, rum cherry, or mountain black cherry, is a deciduous tree or shrub of the genus '' Prunus''. Despite being called black cherry, it is not very closely related to the commonly cultivated cherries such as sweet cherry (''P. avium''), sour cherry (''P. cerasus'') and Japanese flowering cherries (''P. serrulata'', ''P. speciosa'', ''P. sargentii'', ''P. incisa'', etc.) which belong to ''Prunus'' subg. ''Cerasus''. Instead, ''P. serotina'' belongs to ''Prunus'' subg. ''Padus'', a subgenus also including Eurasian bird cherry (''P. padus'') and chokecherry (''P. virginiana''). The species is widespread and common in North America and South America. Black cherry is closely related to the chokecherry (''P. virginiana''); chokecherry, however, tends to be shorter (a shrub or small tree) and has smaller, less glossy ...

Prunus Cerasus
''Prunus cerasus'' (sour cherry, tart cherry, or dwarf cherry) is a species of '' Prunus'' in the subgenus '' Cerasus'' ( cherries), native to much of Europe and southwest Asia. It is closely related to the sweet cherry ('' Prunus avium''), but has a fruit that is more acidic. Its sour pulp is edible. The tree is smaller than the sweet cherry (growing to a height of 4–10 m), has twiggy branches, and its crimson-to-near-black cherries are borne upon shorter stalks. There are two main varieties (groups of cultivars) of the sour cherry: the dark-red Morello cherry and the lighter-red Amarelle cherry. Origins and cultivation ''Prunus cerasus'', a tetraploid with 2n=32 chromosomes, is thought to have originated as a natural hybrid between '' Prunus avium'' and '' Prunus fruticosa'' in the Iranian Plateau or Eastern Europe where the two species come into contact. '' Prunus fruticosa'' is believed to have provided its smaller size and sour tasting fruit. The hybrids then stabiliz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Prunus
''Prunus'' is a genus of trees and shrubs, which includes (among many others) the fruits plums, cherries, peaches, nectarines, apricots, and almonds. Native to the North American temperate regions, the neotropics of South America, and the paleotropics of Asia and Africa, 430 different species are classified under ''Prunus''. Many members of the genus are widely cultivated for their fruit and for decorative purposes. ''Prunus'' fruit are drupes, or stone fruits. The fleshy mesocarp surrounding the endocarp is edible while the endocarp itself forms a hard, inedible shell called the pyrena ("stone" or "pit"). This shell encloses the seed (or "kernel") which is edible in many species (such as almonds) but poisonous in others (such as apricots). Besides being eaten off the hand, most ''Prunus'' fruit are also commonly used in processing, such as jam production, canning, drying, and seeds for roasting.

Malus Sylvestris
''Malus sylvestris'', the European crab apple, is a species of the genus '' Malus'', native to Europe. Its scientific name means "forest apple" and the truly wild tree has thorns. Description Wild apple has an expanded crown and often appears more like a bush than a tree. It can live 80–100 years and grow up to tall with trunk diameters of . Due to its weak competitiveness and high light requirement, wild apple is found mostly at the wet edge of forests, in farmland hedges or on very extreme, marginal sites. The flowers are hermaphrodite and are pollinated by insects. Progenitor of cultivated apples In the past ''M. sylvestris'' was thought to be the most important ancestor of the cultivated apple (''M. domestica''), which has since been shown to have been primarily derived from the central Asian species '' M. sieversii''.

Malus Pumila
An apple is an edible fruit produced by an apple tree (''Malus domestica''). Apple trees are cultivated worldwide and are the most widely grown species in the genus ''Malus''. The tree originated in Central Asia, where its wild ancestor, '' Malus sieversii'', is still found today. Apples have been grown for thousands of years in Asia and Europe and were brought to North America by European colonists. Apples have religious and mythological significance in many cultures, including Norse, Greek, and European Christian tradition. Apples grown from seed tend to be very different from those of their parents, and the resultant fruit frequently lacks desired characteristics. Generally, apple cultivars are propagated by clonal grafting onto rootstocks. Apple trees grown without rootstocks tend to be larger and much slower to fruit after planting. Rootstocks are used to control the speed of growth and the size of the resulting tree, allowing for easier harvesting. There are more ...
