Prunus Mandshurica
''Prunus mandshurica'', also called Manchurian apricot and scout apricot, is a tree in the genus ''Prunus''. It was first described by Karl Maximovich in 1883 as a variety of the Siberian apricot (Tibetan apricot) '' Prunus armeniaca''. It is resistant to cold and is native to northeast China, Korea, and Manchuria. It is highly susceptible to plum pox potyvirus. Description ''Prunus mandshurica'' is a deciduous, broad-leaved tree, which grows to a height of about . The inner bark is red and the outer bark is black. The leaves are oval, with an elongated tip (acuminate or caudate), some hairs, and serrated edges. The tree grows best in loam soils. Its petioles are . The sepals and petals are oval, while the length of the stamens is similar to that of the stigma, which is cup-shaped. Flowers appear in spring and are white or pale pink. Fruits appear in late summer and are yellow with some red. In the autumn, the leaves turn golden orange. Uses Seed oil from ''P. mandshuri ...

Karl Maximovich
Carl Johann Maximovich (also Karl Ivanovich Maximovich, Russian: Карл Иванович Максимович; 23 November 1827 in Tula, Russia – 16 February 1891 in Saint Petersburg) was a Russian botanist. Maximovich spent most of his life studying the flora of the countries he had visited in the Far East, and naming many new species. He worked at the Saint Petersburg Botanical Gardens from 1852 as curator of the herbarium collection, becoming Director in 1869. History Born a Baltic-German, his name at birth was Karl Ivanovich Maksimovich, but he changed it to the German version of his name for his scientific work.Japan’s botanical sunrise plant exploration around the Meiji Restoration Peter Barnes (originally published in Curtis's Botanical Magazine 18(1): ...

Biodiesel
Biodiesel is a form of diesel fuel derived from plants or animals and consisting of long-chain fatty acid esters. It is typically made by chemically reacting lipids such as animal fat (tallow), soybean oil, or some other vegetable oil with an alcohol, producing a methyl, ethyl or propyl ester by the process of transesterification. Unlike the vegetable and waste oils used to fuel converted diesel engines, biodiesel is a drop-in biofuel, meaning it is compatible with existing diesel engines and distribution infrastructure. However, it is usually blended with petrodiesel (typically to less than 10%) since most engines cannot run on pure Biodiesel without modification. Biodiesel blends can also be used as heating oil. The US National Biodiesel Board defines "biodiesel" as a mono-alkyl ester. Blends Blends of biodiesel and conventional hydrocarbon-based diesel are most commonly distributed for use in the retail diesel fuel marketplace. Much of the world uses a system know ...

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, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a 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 reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apricots
An apricot (, ) is a fruit, or the tree that bears the fruit, of several species in the genus ''Prunus''. Usually, an apricot is from the species '' P. armeniaca'', but the fruits of the other species in ''Prunus'' sect. ''Armeniaca'' are also called apricots. Etymology ''Apricot'' first appeared in English in the 16th century as ''abrecock'' from the Middle French ''aubercot'' or later ''abricot'', from Spanish '' albaricoque'' and Catalan ''a(l)bercoc'', in turn from Arabic الْبَرْقُوق (al-barqūq, "the plums"), from Byzantine Greek βερικοκκίᾱ (berikokkíā, "apricot tree"), derived from late Greek ''πραικόκιον'' (''praikókion'', "apricot") from Latin '' ersica ("peach")praecocia'' (''praecoquus'', "early ripening"). Species Apricots are species belonging to ''Prunus'' sect. ''Armeniaca''. The taxonomic position of '' P. brigantina'' is disputed. It is grouped with plum species according to chloroplast DNA sequences, but more closely r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manchuria
Manchuria is an exonym (derived from the endo demonym " Manchu") for a historical and geographic region in Northeast Asia encompassing the entirety of present-day Northeast China (Inner Manchuria) and parts of the Russian Far East (Outer Manchuria). Its meaning may vary depending on the context: * Historical polities and geographical regions usually referred to as Manchuria: ** The Later Jin (1616–1636), the Manchu-led dynasty which renamed itself from "Jin" to "Qing", and the ethnicity from "Jurchen" to "Manchu" in 1636 ** the subsequent duration of the Qing dynasty prior to its conquest of China proper (1644) ** the northeastern region of Qing dynasty China, the homeland of Manchus, known as "Guandong" or "Guanwai" during the Qing dynasty ** The region of Northeast Asia that served as the historical homeland of the Jurchens and later their descendants Manchus ***Qing control of Dauria (the region north of the Amur River, but in its watershed) was contested in 1643 when ...

Liaoning
Liaoning () is a coastal province in Northeast China that is the smallest, southernmost, and most populous province in the region. With its capital at Shenyang, it is located on the northern shore of the Yellow Sea, and is the northernmost coastal province of the People's Republic of China. Historically a gateway between China proper and Manchuria, the modern Liaoning province was established in 1907 as Fengtian or Fengtien province and was renamed Liaoning in 1929. It was also known at that time as Mukden Province for the Manchu name of ''Shengjing'', the former name of Shenyang. Under the Japanese-puppet Manchukuo regime, the province reverted to its 1907 name, but the name Liaoning was restored for a brief time in 1945 and then again in 1954. Liaoning borders the Yellow Sea ( Korea Bay) and Bohai Sea in the south, North Korea's North Pyongan and Chagang provinces in the southeast, Jilin to the northeast, Hebei to the southwest, and Inner Mongolia to the northwest.

Cultivar
A cultivar is a type of cultivated plant that people have selected for desired traits and when propagated retain those traits. Methods used to propagate cultivars include: division, root and stem cuttings, offsets, grafting, tissue culture, or carefully controlled seed production. Most cultivars arise from purposeful human manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word ''cultivar''''Cultivar'' () has two meanings, as explained in ''Formal definition'': it is a classification category and a taxonomic unit within the category. When referring to a taxon, the word does not apply to an individual plant but to all plants that share the unique characteristics that define the cultivar. was coined as a term meaning "cultivated variety ...

Traditional Chinese Medicine
Traditional Chinese medicine (TCM) is an alternative medical practice drawn from traditional medicine in China. It has been described as "fraught with pseudoscience", with the majority of its treatments having no logical mechanism of action. Medicine in traditional China encompassed a range of sometimes competing health and healing practices, folk beliefs, literati theory and Confucian philosophy, herbal remedies, food, diet, exercise, medical specializations, and schools of thought. In the early twentieth century, Chinese cultural and political modernizers worked to eliminate traditional practices as backward and unscientific. Traditional practitioners then selected elements of philosophy and practice and organized them into what they called "Chinese medicine" (''Zhongyi''). In the 1950s, the Chinese government sponsored the integration of Chinese and Western medicine, and in the Great Proletarian Cultural Revolution of the 1960s, promoted Chinese medicine as inexpensive a ...

Phloretin
Phloretin is a dihydrochalcone, a type of natural phenol. It can be found in apple tree leaves and the Manchurian apricot. Metabolism In rats, ingested phlorizin is converted into phloretin by hydrolytic enzymes in the small intestine. Phloretin hydrolase hydrolyses phloretin into phloretic acid and phloroglucinol. Pharmacological research In an animal model, phloretin inhibited active transport of glucose into cells by SGLT1 and SGLT2, though the inhibition is weaker than by its glycoside phlorizin. An important effect of this is the inhibition of glucose absorption by the small intestine and the inhibition of renal glucose reabsorption. Phloretin also inhibits a variety of urea transporters. It induces urea loss and diuresis when coupled with high protein diets. Phloretin has been found to inhibit weight gain and improve metabolic homeostasis in mice fed with high-fat diet. Phloretin inhibits aquaporin 9 (AQP9) on mouse hepatocyte A hepatocyte is a cell of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prunus Sibirica
''Prunus sibirica'', called Siberian apricot (), is a species of shrub or small tree native to northern China, Korea, Mongolia, and eastern Siberia. It is in the genus ''Prunus'' in the rose family, Rosaceae, one of several species whose fruit are called apricot, although this species is rarely cultivated for its fruit. The species was named by Carl Linnaeus in 1753. Description The species is highly genetically diverse. It grows in the form of a small tree with spreading branches and reaches a height of . It is very frost resistant and can survive temperatures down to . The tree's bark is dark grey, while the bark of the branches is reddish to dark brown, sparsely hairy at first, but soon glabrous. The reddish-brown winter buds are ovoid to conical, 2–4 mm long and the edges of the bud scales are hairy. The simple leaves have stipules. The petiole of the leaves is initially hairy, but soon bald, and is red with a length of 2 to 3.5 cm and few if any glands. The sim ...

Petiole (botany)
In botany, the petiole () is the stalk that attaches the leaf blade to the stem, and is able to twist the leaf to face the sun. This gives a characteristic foliage arrangement to the plant. Outgrowths appearing on each side of the petiole in some species are called stipules. Leaves with a petiole are said to be petiolate, while leaves lacking a petiole are called sessile or apetiolate. Description The petiole is a stalk that attaches a leaf to the plant stem. In petiolate leaves, the leaf stalk may be long, as in the leaves of celery and rhubarb, or short. When completely absent, the blade attaches directly to the stem and is said to be sessile. Subpetiolate leaves have an extremely short petiole, and may appear sessile. The broomrape family Orobanchaceae is an example of a family in which the leaves are always sessile. In some other plant groups, such as the speedwell genus '' Veronica'', petiolate and sessile leaves may occur in different species. In the grasses (Poaceae), ...

Bernhard Adalbert Emil Koehne
Bernhard Adalbert Emil Koehne (12 February 1848 – 12 October 1918) was a German botanist and dendrologist born near Striegau, a town known today as Strzegom, Poland. Koehne was a professor of botany in Berlin and was a leading authority of the plant family Lythraceae. In Adolf Engler's treatise ''Das Pflanzenreich'' ("The Plant Kingdom"), he was author of the chapter on Lythraceae. He also made important contributions involving Lythraceae to Engler and Karl Prantl's ''Die Natürlichen Pflanzenfamilien'' ("The Natural Plant Families"), as well as to Karl Friedrich Philipp von Martius' ''Flora Brasiliensis''. Another noted written effort by Koehne was the 1893 ''Deutsche Dendrologie'' ("German Dendrology"). Two plant genera have been named in his honor; '' Koehneola'' from Cuba, in the (family Asteraceae) was named in 1901, and ''Koehneria ''Koehneria'' is a monotypic genus of flowering plants belonging to the family Lythraceae.
