Castanea Crenata
''Castanea crenata'', the Japanese chestnut or Korean chestnut, is a species of chestnut native to Japan and Korea. ''Castanea crenata'' exhibits resistance to ''Phytophthora cinnamomi'', the fungal pathogen that causes ink disease in several Castanea species. The mechanism of resistance of ''Castanea crenata'' to ''Phytophthora cinnamomi'' may derive from its expression of the Cast_Gnk2-like gene. Description ''Castanea crenata'' is a small to medium-sized deciduous tree growing to tall. The leaf, leaves are similar to those of the sweet chestnut, though usually a little smaller, long and broad. The flowers of both sexes are borne in long, upright catkins, the male flowers in the upper part and female flowers in the lower part. They appear in summer, and by autumn, the female flowers develop into spiny Calybium and cupule, cupules containing 3–7 brownish nut (fruit), nuts that are shed during October.

Philipp Franz Von Siebold
Philipp Franz Balthasar von Siebold (17 February 1796 – 18 October 1866) was a German physician, botanist and traveller. He achieved prominence by his studies of Japanese flora (plants), flora and fauna (animals), fauna and the introduction of Western medicine in Japan. He was the father of the first female Japanese doctor educated in Western medicine, Kusumoto Ine. Career Early life Born into a family of doctors and professors of medicine in Würzburg (then in the Prince-Bishopric of Würzburg, later part of Bavaria), von Siebold initially studied medicine at the University of Würzburg from November 1815, where he became a member of the German Student Corps, Corps Moenania Würzburg. One of his professors was Franz Xaver Heller (1775–1840), author of the ' ("Flora of the Grand Duchy of Würzburg", 1810–1811). Ignaz Döllinger (1770–1841), his professor of anatomy and physiology, however, most influenced him. Döllinger was one of the first professors to under ...

Edible Nuts And Seeds
An edible item is any item that is safe for humans to eat. "Edible" is differentiated from " eatable" because it does not indicate how an item tastes, only whether it is fit to be eaten. Nonpoisonous items found in nature – such as some mushrooms, insects, seaweed, and so forth – are referred to as edible. Processed items that normally are not ingested but are specially manufactured to be so, like edible underwear or edible packaging, are also labeled as edible. Edible items in nature Humans eat thousands of plant species; there may be as many as 75,000 edible species of angiosperms, of which perhaps 7,000 are often eaten. Edible plants found in nature include flowers, seeds, berries, seaweed, and cacti. Being able to identify the versions of these plants that are safe to eat is an important survival skill. Some fungi, including certain types of mushrooms, are also edible. Many animals are also edible, including domesticated livestock as well as wild insects, amphibians ...

Trees Of Korea
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, e.g., including only woody plants with secondary growth, only plants that are usable as lumber, or only plants above a specified height. But wider definitions include taller palms, tree ferns, bananas, and bamboos. Trees are not a monophyletic taxonomic group but consist of a wide variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some trees reaching several thousand years old. Trees evolved around 400 million years ago, and it is estimated that there are around three trillion mature trees in the world currently. A tree typically has many secondary branches supported clear of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Castanea
The chestnuts are the deciduous trees and shrubs in the genus ''Castanea'', in the beech family Fagaceae. The name also refers to the edible nuts they produce. They are native to temperate regions of the Northern Hemisphere. Description Chestnut trees are of moderate growth rate (for the Chinese chestnut tree) to fast-growing for American and European species. Their mature heights vary from the smallest species of chinkapins, often shrubby,''Chestnuts, Horse-Chestnuts, and Ohio Buckeyes'' . In Yard and Garden Brief, Horticulture department at University of Minnesota. to the giant of past American forests, '' C. dentata'' that could reach . Between these extremes are ...

Precoce Migoule
The Precoce Migoule is a chestnut hybrid (CA 48), a natural cross between a European chestnut (Castanea sativa) and a Japanese chestnut (Castanea crenata). It was discovered by J. Dufrenoy at the orchard of Migoule in Brive-la-Gaillarde. The tree is vigorous and erect growing with growth of a metre (3 ft) or more in a season if the conditions are right. It is a large sized chestnut tree with height reaching 20 m (60 ft) or more and 7.5-10 m (25-35 ft) wide. Trees start to bear after 3 to 5 years. Full nut production in 12 - 20 years depending on the location. This hybrid can be grown in many areas where grapes are grown. It is cold hardy to -28C (-20F In an orchard with South West orientation it can be grown up to 500 m (1640 ft) elevation. It is an early ripening variety - great for northern climates where late ripening varieties can get damaged by frost - a very dependable producer in cool region It blooms early and is frost sensitive but can produce nuts from secondary ...

Bouche De Betizac
Bouche de Bétizac is a French chestnut cultivar developed in 1962 by INRA at the station of Malemort-sur-Corrèze near Brive. It is a controlled hybrid between Castanea sativa and Castanea crenata (female Bouche rouge × male Castanea crenata CA04). This variety produces large to very large chestnuts. It has very good flavor for a hybrid. With Marigoule, it is the variety currently most cultivated in the French chestnut groves because it is very productive (3 tons per hectare on average). Its fruit is bright, light chestnut-brown quickly turning brown and dark brown. Culture The upright tree of moderate height can be planted tightly in chestnut groves (7 m x 7 m), with 200 productive trees per hectare. In addition, its productivity matures quickly. In drip irrigated culture, in Bordeaux, the cumulative production at the age of 5 to 7 years can be between 21 and 40 kg per tree. "Bouche de Bétizac" is pollen sterile and is pollinated by many varieties such as Belle Epine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colossal (chestnut)
The chestnut cultivar Colossal originates from the USA - California Central Valley. It is a ''Castanea sativa'' × ''Castanea crenata'' hybrid that is cold hardy to . The tree can be grown in Zones 4-8, blooms early, and is pollen sterile. Colossal is chestnut blight, root rot and kernel rot susceptible. History It is probable that ‘Colossal’ was a seedling of one of Felix Gillet’s high quality French (Castanea sativa) cultivars, pollinized by a Japanese (Castanea crenata) tree. The original Colossal tree and its pollinizer were planted in approximately 1888-1890 by Benjamin Tonella in Nevada City, California The most likely source for the trees was The Barren Hill Nursery of Felix Gillet. Gillet imported some of the best French chestnut cultivars and also imported an assortment of Japanese chestnuts. Gillet died in 1908 and the nursery was bought by C. E. Parsons. Parsons introduced the Colossal chestnut commercially in 1925. In 2000, the original ‘Colossal’ tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Chestnut
The American chestnut (''Castanea dentata'') is a large, fast-growing deciduous tree of the Fagaceae, beech family native to eastern North America. As is true of all species in the genus ''Chestnut, Castanea'', the American chestnut produces Bur, burred fruit with edible nuts. The American chestnut was once common in its Appalachian Mountains, Appalachian Mountain range and was a Dominance (ecology), dominant species in the oak-chestnut forest region of its central and southern range. During the early to mid-20th century, American chestnut trees were devastated by chestnut blight, a fungal disease that came from Castanea crenata, Japanese chestnut trees that were introduced into North America from Japan. It is estimated that the blight killed between three and four billion American chestnut trees in the first half of the 20th century, beginning in 1904.Griffin, Gary"Recent advances in research and management of chestnut blight on American chestnut" Phytopathology (journal), Phyto ...

Genetic Engineering
Genetic engineering, also called genetic modification or genetic manipulation, is the modification and manipulation of an organism's genes using technology. It is a set of Genetic engineering techniques, technologies used to change the genetic makeup of cells, including the transfer of genes within and across species boundaries to produce improved or novel organisms. New DNA is obtained by either isolating and copying the genetic material of interest using recombinant DNA methods or by Artificial gene synthesis, artificially synthesising the DNA. A Vector (molecular biology), construct is usually created and used to insert this DNA into the host organism. The first recombinant DNA molecule was made by Paul Berg in 1972 by combining DNA from the monkey virus SV40 with the Lambda phage, lambda virus. As well as inserting genes, the process can be used to remove, or "Gene knockout, knock out", genes. The new DNA can either be inserted randomly or Gene targeting, targeted to a spe ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera. Hybrids are not always intermediates between their parents such as in blending inheritance (a now discredited theory in modern genetics by particulate inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridization, which include genetic and morph ...
