Malus Floribunda
''Malus floribunda'', common name Japanese flowering crabapple, Japanese crab, purple chokeberry, or showy crabapple, originates from Japan and East Asia. It may be a hybrid (biology)#In plants, hybrid of ''M. toringo'' with ''M. baccata'', in which case it would be written as ''Malus'' × ''floribunda''. Description ''Malus floribunda'' forms a round-headed, deciduous tree up to in height, with narrow leaves on arching branches. The flowers, appearing in spring, are white or pale pink, opening from crimson buds. The red or yellow fruit is about 1 cm in diameter, ripening in autumn. Resistance Tree has good disease resistance to apple scab and powdery mildew. The initiators of the PRI disease resistant apple breeding program have discovered that ''Malus floribunda'' has resistance to the apple scab and founded the program to introduce this ''VF gene'' into cultivated apples. Their work had been progressing with great success. Awards This crabapple species is considered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 (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 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 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 understand and tr ...

Louis Benoit Van Houtte
Louis Benoît van Houtte (29 June 1810, in Ypres – 9 May 1876, in Ghent) was a Belgian horticulturist who was with the Jardin Botanique de Brussels between 1836 and 1838 and is best known for the journal ''Flore des Serres et des Jardins de l'Europe'', produced with Charles Lemaire and M. Scheidweiler, an extensive work boasting more than 2,000 coloured plates in 23 volumes published between 1845 and 1883. Early in his career van Houtte worked in Brussels for the ministry of finance. All his leisure time was spent on botany at the botanical garden and private estates. He was on good terms with men like the peony breeder M. Parmentier of Enghien, the Knight Parthon de Von, and d’Enghien and befriended local gardeners. Together with Charles François Antoine Morren, van Houtte founded ''L'Horticulteur Belge'' (1833–1838), a monthly magazine, in November 1832. The 119 hand-coloured plates that were published are engravings or sometimes lithographs. There are also 78 plat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Name
In biology, a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life; and is often contrasted with the scientific name for the same organism, which is Latinized. A common name is sometimes frequently used, but that is not always the case. In chemistry, IUPAC defines a common name as one that, although it unambiguously defines a chemical, does not follow the current systematic naming convention, such as acetone, systematically 2-propanone, while a vernacular name describes one used in a lab, trade or industry that does not unambiguously describe a single chemical, such as copper sulfate, which may refer to either copper(I) sulfate or copper(II) sulfate. Sometimes common names are created by authorities on one particular subject, in an attempt to make it possible for members of the general public (including such interested par ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending 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 hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Malus Floribunda "Golden Hornet" - Geograph
''Malus'' ( or ) is a genus of about 30–55 species of small deciduous trees or shrubs in the family Rosaceae, including the domesticated orchard apple, crab apples, wild apples, and rainberries. The genus is native to the temperate zone of the Northern Hemisphere. Description Apple trees are typically talI at maturity, with a dense, twiggy crown. The leaves are long, alternate, simple, with a serrated margin. The flowers are borne in corymbs, and have five petals, which may be white, pink, or red, and are perfect, with usually red stamens that produce copious pollen, and a half-inferior ovary; flowering occurs in the spring after 50–80 growing degree days (varying greatly according to subspecies and cultivar). Many apples require cross-pollination between individuals by insects (typically bees, which freely visit the flowers for both nectar and pollen); these are called self-sterile, so self-pollination is impossible, making pollinating insects essential.

Apple Scab
Apple scab is a common disease of plants in the rose family ( Rosaceae) that is caused by the ascomycete fungus ''Venturia inaequalis''. While this disease affects several plant genera, including ''Sorbus, Cotoneaster,'' and '' Pyrus'', it is most commonly associated with the infection of ''Malus'' trees, including species of flowering crabapple, as well as cultivated apple. The first symptoms of this disease are found in the foliage, blossoms, and developing fruits of affected trees, which develop dark, irregularly-shaped lesions upon infection. Although apple scab rarely kills its host, infection typically leads to fruit deformation and premature leaf and fruit drop, which enhance the susceptibility of the host plant to abiotic stress and secondary infection.Jha, G., Thakur, K., & Thakur, P.

PRI Disease Resistant Apple Breeding Program
The PRI disease resistant apple breeding program is a joint project of the Purdue University, Rutgers University, and the University of Illinois, to breed apple cultivars to be resistant to apple scab. The initialism stands for the three involved universities: Purdue, Rutgers and Illinois. Formation During the early 20th century, C. S. Crandall carried out intensive studies of crosses between the cultivated apples and crab apples, with the goal of scab resistance. However, Crandall didn't see any fruits of his investigations. L. Fredric Hough, then a graduate student at the University of Illinois, studied Crandall's work. Hough published a paper in 1944, leading to a 1945 collaboration with Purdue University Pathology, pathologist J. Ralph Shay. Hough then relocated to Rutgers and the collaborative effort was extended there. The program The modified backcross breeding strategy used cultivated apple with recurrent parents from selected susceptible members of the wild ancestral genus ...

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 (North Yorkshire), Rosemoor (Devon) and Bridgewater (Greater Manchester); flower shows including the Chelsea Flower Show, Hampton Court Palace Flower Show, Tatton Park Flower Show and Cardiff Flower Show; community gardening schemes; Britain in Bloom and a vast educational programme. It also supports training for professional and amateur gardeners. the president was Keith Weed and the director general was Sue Biggs CBE. History Founders The creation of a British horticultural society was suggested by John Wedgwood (son of Josiah Wedgwood) in 1800. His aims were fairly modest: he wanted to hold regular meetings, allowing the society's members the opportunity to present papers on their horticultural activities and discoveries, to enc ...

Award Of Garden Merit
The Award of Garden Merit (AGM) is a long-established annual award for plants by the British Royal Horticultural Society (RHS). It is based on assessment of the plants' performance under UK growing conditions. History The Award of Garden Merit is a mark of quality awarded, since 1922, to garden plants (including trees, vegetables and decorative plants) by the United Kingdom, Royal Horticultural Society (RHS). Awards are made annually after plant trials intended to judge the plants' performance under UK growing conditions. Trials may last for one or more years, depending on the type of plant being analyzed, and may be performed at Royal Horticulture Society Garden in Wisley and other gardens or after observation of plants in specialist collections. Trial reports are made available as booklets and on the website. Awards are reviewed annually in case plants have become unavailable horticulturally, or have been superseded by better cultivars. Similar awards The award should not be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Applecrab
Applecrabs are various hybrids between crabapples and apples. They are bred for varying reasons, including disease resistance and use in cold climates because they are often hardier than apple trees and their fruit has the good eating qualities of apples. Applecrabs are sometimes distinguished from apples if the fruit diameter is less than . Cold-hardy applecrabs Director of the Canadian Central Experimental Farm William Saunders (1836–1914) produced a number of such hybrids as part of an effort to develop good-quality eating apples for the Canadian prairies by crossing the domesticated apple cultivars with selected winter-hardy crabapple species. Cultivars include: * Malus 'Columbia', from one of Saunders' early experiments crossing ''M. baccata'' (from Siberia) with relatively hardy apples. * Malus 'Kerr', from crossing 'Dolgo' crabapple and 'Haralson' apple. * Malus 'Osman', from one of Saunders' early experiments crossing ''M. baccata'' with relatively hardy apples. * Mal ...
