Paulownia
''Paulownia'' ( ) is a genus of seven to 17 species of hardwood tree (depending on taxonomic authority) in the family Paulowniaceae, the order Lamiales. They are present in much of China, south to northern Laos and Vietnam and are long cultivated elsewhere in eastern Asia, notably in Japan and Korea. It was introduced to North America in 1844 from Europe and Asia where it was originally sought after as an exotic ornamental tree. Its fruits (botanically capsules) were also used as packaging material for goods shipped from East Asia to North America, leading to ''Paulownia'' groves where they were dumped near major ports. The tree has not persisted prominently in US gardens, in part due to its overwintering brown fruits that some consider ugly. In some areas it has escaped cultivation and is found in disturbed plots. Some US authorities consider the genus an invasive species, but in Europe, where it is also grown in gardens, it is not regarded as invasive. The genus, originally ...

Paulownia Tomentosa
''Paulownia tomentosa'', common names princess tree, empress tree, or foxglove-tree, is a deciduous hardwood tree in the family Paulowniaceae, native to central and western China. It is an extremely fast-growing tree with seeds that disperse readily, and is a persistent exotic invasive species in North America, where it has undergone naturalisation in large areas of the Eastern US. ''P. tomentosa'' has also been introduced to Western and Central Europe, and is establishing itself as a naturalised species there as well. Etymology The generic name ''Paulownia'' honours Anna Pavlovna of Russia, who was Queen Consort of the Netherlands from 1840 to 1849. The specific epithet ''tomentosa'' is a Latin word meaning ‘covered in hairs’. Description This tree grows tall, with large heart-shaped to five-lobed leaves across, arranged in opposite pairs on the stem. On young growth, the leaves may be in whorls of three and be much bigger than the leaves on more mature growth. The l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paulownia Elongata
''Paulownia elongata'' is a species of tree in the family Paulowniaceae, native to Asia. The plant's leaves are very large and pubescent ('fuzzy—hairy'). This species can withstand a very wide range of environmental conditions. It does not grow at higher altitudes however. Uses Cultivation ''Paulownia elongata'' is cultivated as an ornamental tree for use in gardens and parks. It is selected for its purple flowers, and its shade tolerance. Biofuel The tree is planted and grown as feedstock for biofuel production. Due to the large quantity of biomass produced annually, it is suited for use as biofuel feedstock. Lumber ''Paulownia elongata'' is planted as a forestry tree producing strong, yet light, wood. It is grown for lumber in North America and China. Commercial plantations are normally established from selected clones resulting from micropropagation Micropropagation or tissue culture is the practice of rapidly multiplying plant stock material to produce many pr ...

Paulownia Fortunei
''Paulownia fortunei'' commonly called the dragontree, dragon tree or Fortune's empress tree, is a deciduous tree in the family Paulowniaceae, native to southeastern China (including Taiwan), Laos and Vietnam. It is an extremely fast-growing tree, due to its use of C carbon fixation, and is planted for timber harvesting. It appears to be nowhere near as dangerously invasive as ''Paulownia tomentosa''. Uses Aside from its use as a cheap timber tree, it is being studied for use in phytoremediation and carbon sequestration. ''P. fortunei'' is cultivated as an ornamental tree in parks and gardens. Its cultivar ='Minfast' has gained the Royal Horticultural Society The Royal Horticultural Society (RHS), founded in 1804 as the Horticultural Society of London, is the UK's leading gardening charity. The RHS promotes horticulture through its five gardens at Wisley (Surrey), Hyde Hall (Essex), Harlow Carr (Nor ...'s Award of Garden Merit. References {{Taxonbar, from=Q10771199 P ...

Philipp Franz Von Siebold
Philipp Franz Balthasar von Siebold (17 February 1796 – 18 October 1866) was a German physician, botanist and traveler. He achieved prominence by his studies of Japanese flora and 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 Bishopric of Würzburg, later part of Bavaria), Siebold initially studied medicine at the University of Würzburg from November 1815, where he became a member of the 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 understand and treat medicine as a natural science. Siebold stayed wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soil Biota
Soil biology is the study of microbial and faunal activity and ecology in soil. Soil life, soil biota, soil fauna, or edaphon is a collective term that encompasses all organisms that spend a significant portion of their life cycle within a soil profile, or at the soil-litter interface. These organisms include earthworms, nematodes, protozoa, fungi, bacteria, different arthropods, as well as some reptiles (such as snakes), and species of burrowing mammals like gophers, moles and prairie dogs. Soil biology plays a vital role in determining many soil characteristics. The decomposition of organic matter by soil organisms has an immense influence on soil fertility, plant growth, soil structure, and carbon storage. As a relatively new science, much remains unknown about soil biology and its effect on soil ecosystems. Overview The soil is home to a large proportion of the world's biodiversity. The links between soil organisms and soil functions are complex. The interconnec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grand Duchess Anna Pavlovna Of Russia
Anna Pavlovna of Russia (russian: Анна Павловна ; nl, Anna Paulowna ; – 1 March 1865) was a queen of the Netherlands by marriage to king William II of the Netherlands. She was a Russian patriot who upheld a strict royal etiquette in the Netherlands, where she never felt at home, and identified more as an Imperial Russian Grand Duchess than a Dutch queen. She had no political influence, but was active within charity. Youth Anna Pavlovna was born in 1795 at Gatchina Palace, the eighth child and sixth daughter of Paul I of Russia and Empress Maria Feodorovna (born Sophie Dorothea of Württemberg), and thus was ''Her Imperial Highness Grand Duchess Anna Pavlovna of Russia''. Her father became emperor in 1796, and was deposed and killed in 1801, when she was six years old. Anna Pavlovna's brother Alexander succeeded to the throne. Anna was raised by her mother at the summer residence of the Romanovs, Tsarskoye Selo. She spent her childhood there with her two younger ...

Tsar
Tsar ( or ), also spelled ''czar'', ''tzar'', or ''csar'', is a title used by East and South Slavic monarchs. The term is derived from the Latin word ''caesar'', which was intended to mean "emperor" in the European medieval sense of the term—a ruler with the same rank as a Roman emperor, holding it by the approval of another emperor or a supreme ecclesiastical official (the Pope or the Ecumenical Patriarch)—but was usually considered by western Europeans to be equivalent to "king". It lends its name to a system of government, tsarist autocracy or tsarism. "Tsar" and its variants were the official titles of the following states: * Bulgarian Empire (First Bulgarian Empire in 681–1018, Second Bulgarian Empire in 1185–1396), and also used in Tsardom of Bulgaria, in 1908–1946 * Serbian Empire, in 1346–1371 * Tsardom of Russia, in 1547–1721 (replaced in 1721 by ''imperator'' in Russian Empire, but still remaining in use, also officially in relation to several regi ...

Paul I Of Russia
Paul I (russian: Па́вел I Петро́вич ; – ) was Emperor of Russia from 1796 until his assassination. Officially, he was the only son of Peter III and Catherine the Great, although Catherine hinted that he was fathered by her lover Sergei Saltykov.Aleksandr Kamenskii, ''The Russian Empire in the Eighteenth Century: Searching for a Place in the World'' (1997) pp 265–280. Paul remained overshadowed by his mother for most of his life. He adopted the laws of succession to the Russian throne—rules that lasted until the end of the Romanov dynasty and of the Russian Empire. He also intervened in the French Revolutionary Wars and, toward the end of his reign, added Kartli and Kakheti in Eastern Georgia into the empire, which was confirmed by his son and successor Alexander I. He was ''de facto'' Grand Master of the Order of Hospitallers from 1799 to 1801 and ordered the construction of a number of Maltese thrones. Paul's pro-German sentiments and unpredictable ...
