Russeting
Russeting or russetting is an abnormality of fruit skin which manifests in russet-colored (brownish) patches that are rougher than healthy skin. It is a common feature in apples and pears. Russeting is typically an undesirable trait, which reduces the storage life of fruits and makes their appearance unattractive to consumers, although some cultivars, so-called russet apples, are appreciated for the feature. Causes In apples and pears, russet results from micro-cracking of the cuticle, the outer epidermal layer of the fruit. The cuticle is a natural waterproof barrier composed of a polymerized cutin matrix embedded with waxes, which protects the fruit from outside stresses, and helps maintain post-harvest preservation. When the cuticle cracks, a corky suberized layer is formed on the fruit skin. Apples are particularly susceptible to russet. Many naturally-occurring varieties exhibit the feature consistently, while other cultivars may develop russet due to environmental stress ...

Russet Apple
Russet apples are varieties and cultivars of apples that regularly exhibit russeting, partial or complete coverage with rough patches of greenish-brown to yellowish-brown colour. While russeting is generally an undesirable trait in modern cultivars, russet varieties are often seen as more traditional, and associated with aromatic flavours. Overview Many apple cultivars have some natural russeting, but some are almost entirely covered in it, notably the Egremont Russet. Russet apples often exhibit a scent and flavour reminiscent of nut (fruit), nuts, and are often very sweet. Despite this, modern apple breeders rarely accept russeting in new apple cultivars. The amount of russeting can be affected by various factors including, weather, disease or pest (organism), pest damage and agrochemical applications (e.g. insecticides, fungicides and Plant hormone, growth regulators). Russet apples also go under the name "rusticoat", "russeting" and "leathercoat". The name "leathercoat" was kn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apple
An apple is a round, edible fruit produced by an apple tree (''Malus'' spp.). Fruit trees of the orchard or domestic apple (''Malus domestica''), the most widely grown in the genus, are agriculture, cultivated worldwide. The tree originated in Central Asia, where its wild ancestor, ''Malus sieversii'', is still found. Apples have been grown for thousands of years in Eurasia before they were introduced to North America by European colonization of the Americas, European colonists. Apples have cultural significance in many mythological, mythologies (including Norse mythology, Norse and Greek mythology, Greek) and religions (such as Christianity in Europe). Apples grown from seeds tend to be very different from those of their parents, and the resultant fruit frequently lacks desired characteristics. For commercial purposes, including botanical evaluation, apple cultivars are propagated by clonal grafting onto rootstocks. Apple trees grown without rootstocks tend to be larger and ...

4 X Conference Pear 2017 A
4 (four) is a number, numeral and digit. It is the natural number following 3 and preceding 5. It is a square number, the smallest semiprime and composite number, and is considered unlucky in many East Asian cultures. Evolution of the Hindu-Arabic digit Brahmic numerals represented 1, 2, and 3 with as many lines. 4 was simplified by joining its four lines into a cross that looks like the modern plus sign. The Shunga would add a horizontal line on top of the digit, and the Kshatrapa and Pallava evolved the digit to a point where the speed of writing was a secondary concern. The Arabs' 4 still had the early concept of the cross, but for the sake of efficiency, was made in one stroke by connecting the "western" end to the "northern" end; the "eastern" end was finished off with a curve. The Europeans dropped the finishing curve and gradually made the digit less cursive, ending up with a digit very close to the original Brahmin cross. While the shape of the character for ...

Fruit
In botany, a fruit is the seed-bearing structure in flowering plants (angiosperms) that is formed from the ovary after flowering. Fruits are the means by which angiosperms disseminate their seeds. Edible fruits in particular have long propagated using the movements of humans and other animals in a symbiotic relationship that is the means for seed dispersal for the one group and nutrition for the other; humans, and many other animals, have become dependent on fruits as a source of food. Consequently, fruits account for a substantial fraction of the world's agricultural output, and some (such as the apple and the pomegranate) have acquired extensive cultural and symbolic meanings. In common language and culinary usage, ''fruit'' normally means the seed-associated fleshy structures (or produce) of plants that typically are sweet (or sour) and edible in the raw state, such as apples, bananas, grapes, lemons, oranges, and strawberries. In botanical usage, the term ''fruit'' als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russet (color)
Russet is a dark brown color with a reddish-orange tinge. As a tertiary color, russet is an equal mix of orange and purple pigments. The first recorded use of russet as a color name in English was in 1562. The source of this color is ''The ISCC-NBS Method of Designating Colors and a Dictionary of Color Names'' (1955) used by stamp collectors to identify the colors of stamps. However, it is widely considered hard to standardize, and the same vary name could be applied to various tones; ''russet'' often has no more specific meaning than ''ruddy'' or ''reddish''. The name of this color derives from russet, a coarse cloth made of wool and dyed with woad and madder to give it a subdued grey or reddish-brown shade. By the statute of 1363, poor English people were required to wear russet. Russet, a color of autumn, is often associated with sorrow or grave seriousness. Anticipating a lifetime of regret, Shakespeare's character Biron says in ''Love's Labour's Lost'', Act V, Scene 2: " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pear
Pears are fruits produced and consumed around the world, growing on a tree and harvested in late summer into mid-autumn. The pear tree and shrub are a species of genus ''Pyrus'' , in the Family (biology), family Rosaceae, bearing the Pome, 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, canning, canned, as juice, Dried fruit, dried, or fermented as perry. 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 ...

Plant Cuticle
A plant cuticle is a protecting film covering the outermost skin layer (epidermis) of leaves, young shoots and other aerial plant organs (aerial here meaning all plant parts not embedded in soil or other substrate) that have no '' periderm''. The film consists of lipid and hydrocarbon polymers infused with wax, and is synthesized exclusively by the epidermal cells. Kolattukudy, PE (1996) Biosynthetic pathways of cutin and waxes, and their sensitivity to environmental stresses. In: Plant Cuticles. Ed. by G. Kerstiens, BIOS Scientific publishers Ltd., Oxford, pp 83-108 Description The plant cuticle is a layer of lipid polymers impregnated with waxes that is present on the outer surfaces of the primary organs of all vascular land plants. It is also present in the sporophyte generation of hornworts, and in both sporophyte and gametophyte generations of mosses. The plant cuticle forms a coherent outer covering of the plant that can be isolated intact by treating plant tissue with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cork (material)
Cork is an impermeable buoyant material. It is the phellem layer of bark tissue which is harvested for commercial use primarily from '' Quercus suber'' (the cork oak), which is native to southwest Europe and northwest Africa. Cork is composed of suberin, a hydrophobic substance. Because of its impermeable, buoyant, elastic, and fire retardant properties, it is used in a variety of products, the most common of which is wine stoppers. The montado landscape of Portugal produces approximately half of the cork harvested annually worldwide, with Corticeira Amorim being the leading company in the industry. Cork was examined microscopically by Robert Hooke, which led to his discovery and naming of the cell. Cork composition varies depending on geographic origin, climate and soil conditions, genetic origin, tree dimensions, age (virgin or reproduction), and growth conditions. However, in general, cork is made up of suberin (average of about 40%), lignin (22%), polysaccharid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suberized
Suberin is a lipophilic, complex polyester biopolymer found in plants. It is composed of long-chain fatty acids (called suberin acids) and glycerol. Suberin is interconnected with cutin and lignin and forms a protective barrier in the epidermal and peridermal cell walls of higher plants. Suberin and lignin are considered covalently linked to lipids and carbohydrates, respectively. Lignin is again covalently linked to suberin, and to a lesser extent to cutin, thus construdting a complex macromolecular matrix. Suberin is a major constituent of cork, and is named after the cork oak, ''Quercus suber''. Its main function is as a barrier to movement of water and solutes. Anatomy and physiology Suberin is highly hydrophobic and a somewhat 'rubbery' material. In roots, suberin is deposited in the radial and transverse/tangential cell walls of the endodermal cells. This structure, known as the Casparian strip or Casparian band, functions to prevent water and nutrients taken up by the root ...
