Phragmidium Bulbosum
''Phragmidium '' is a genus of rust fungus that typically infects plant species in the family Rosaceae. It is characterised by having stalked teliospores borne on telia each having a row of four or more cells. All species have a caeoma which is a diffuse aecidium lacking a peridium. There are a number of species of ''Phragmidium'', most of which are restricted to one or a few host species. Examples include: *'' Phragmidium acuminatum'' on '' Rubus saxatile'' *'' Phragmidium bulbosum'' on ''Rubus fruticosus'' and '' Rubeus caesius'' *'' Phragmidium mucronatum'' *'' Phragmidium sterilis'' on ''Potentilla sterilis'' *''Phragmidium potentillae'' on ''Potentilla anglica'' *''Phragmidium rosae-pimpinellifoliae'' *''Phragmidium rubi-idaei'' on raspberry *''Phragmidium tuberculatum'' on some rose cultivars *''Phragmidium violaceum'' on cultivated blackberry and loganberry Possibly the most commonly encountered is ''P. mucronatum'', found on most species of wild roses including ''Rosa c ...

Johann Heinrich Friedrich Link
Johann Heinrich Friedrich Link (2 February 1767 – 1 January 1851) was a German naturalist and botanist. Biography Link was born at Hildesheim as a son of the minister August Heinrich Link (1738–1783), who taught him love of nature through collection of 'natural objects'. He studied medicine and natural sciences at the Hannoverschen Landesuniversität of Göttingen, and graduated as MD in 1789, promoting on his thesis ''"Flora der Felsgesteine rund um Göttingen"'' (Flora of the rocky beds around Göttingen). One of his teachers was the famous natural scientist Johann Friedrich Blumenbach (1752–1840). He became a private tutor (''Privatdozent'') in Göttingen. In 1792 he became the first professor of the new department of chemistry, zoology and botany at the University of Rostock. During his stay at Rostock, he became an early follower of the antiphlogistic theory of Lavoisier, teaching about the existence of oxygen instead of phlogiston. He was also a proponent of the ...

Rubus Fruticosus
''Rubus fruticosus'' L. is the ambiguous name of a European blackberry species in the genus ''Rubus'' in the rose family. The name has been interpreted in several ways: *The species represented by the type specimen of ''Rubus fruticosus'' L., which is also the type specimen of the genus ''Rubus''. This specimen is considered to match the species '' R. plicatus'', in ''Rubus'' subgenus ''Rubus'', section ''Rubus''. * Various species consistent with Linnaeus' original description of the species, which was based on a mixture of specimens now considered to match ''Rubus ulmifolius'' and ''R. plicatus'' *a species aggregate (group of similar species) ''Rubus fruticosus'' agg. (a ''nomen ambiguum'') that includes most (or rarely all) of a group called ''Rubus'' subgenus ''Rubus'' (or less often: ''Rubus'' section ''Rubus'' ensu latissimo): ** in a narrow sense, sometimes separated as the section ''Glandulosus'' (alternative name: subsection ''Hiemales''), with about 289 microspeci ...

Loganberry
The loganberry (''Rubus'' × ''loganobaccus'') is a hybrid of the North American blackberry (''Rubus ursinus'') and the European raspberry (''Rubus idaeus''). The plant and the fruit resemble the blackberry more than the raspberry, but the fruit color is a dark red, rather than black as in blackberries. Loganberries – which were an accident of berry breeding by James Harvey Logan, for whom they are named – are cultivated commercially and by gardeners. Origin The loganberry was derived from a cross between ''Rubus ursinus'' (''R. vitifolius'') 'Aughinbaugh' ( octaploid) as the female parent and ''Rubus idaeus'' 'Red Antwerp' (diploid) as the male parent (pollen source); the loganberry is hexaploid. It was accidentally created in 1881 in Santa Cruz, California, by the American judge and horticulturist James Harvey Logan (1841–1928). Logan was unsatisfied with the existing varieties of blackberries and tried crossing two varieties of blackberries to produce a supe ...

Blackberry
The blackberry is an edible fruit produced by many species in the genus ''Rubus'' in the family Rosaceae, hybrids among these species within the subgenus ''Rubus'', and hybrids between the subgenera ''Rubus'' and ''Idaeobatus''. The taxonomy of blackberries has historically been confused because of hybridization and apomixis, so that species have often been grouped together and called species aggregates. For example, the entire subgenus ''Rubus'' has been called the ''Rubus fruticosus'' aggregate, although the species ''R. fruticosus'' is considered a synonym of '' R. plicatus''. ''Rubus armeniacus'' ("Himalayan" blackberry) is considered a noxious weed and invasive species in many regions of the Pacific Northwest of Canada and the United States, where it grows out of control in urban and suburban parks and woodlands. Description What distinguishes the blackberry from its raspberry relatives is whether or not the torus ( receptacle or stem) "picks with" (i.e., stays with) th ...

Phragmidium Violaceum
''Phragmidium violaceum'' is a plant pathogen native to Europe, Africa, and the Middle East. It primarily infects ''Rubus'' species. It has been used in the biological control of invasive blackberry species in Chile, Australia, and New Zealand. In 2005, it was discovered growing on Himalayan blackberry plants in Oregon. This accidental introduction does not appear to be infecting native vegetation, so it offers hope for reducing the impact of invasive blackberries in the Pacific Northwest. Symptoms The foliar symptoms that can be found include purple leaf spots along with yellow and tan centers. These can be found on the upper surface of the leaf and can resemble ''Septoria'' leaf spot. On the lower surface of the leaf yellow to orange pustules will be surrounded by a purple tinge. These can resemble cane and leaf rust. The leaves that are severely infected can start to dehydrate as well as start to curl. The leaves that are older and closer to the cane will get infected first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rose
A rose is either a woody perennial flowering plant of the genus ''Rosa'' (), in the family Rosaceae (), or the flower it bears. There are over three hundred species and tens of thousands of cultivars. They form a group of plants that can be erect shrubs, climbing, or trailing, with stems that are often armed with sharp prickles. Their flowers vary in size and shape and are usually large and showy, in colours ranging from white through yellows and reds. Most species are native to Asia, with smaller numbers native to Europe, North America, and northwestern Africa. Species, cultivars and hybrids are all widely grown for their beauty and often are fragrant. Roses have acquired cultural significance in many societies. Rose plants range in size from compact, miniature roses, to climbers that can reach seven meters in height. Different species hybridize easily, and this has been used in the development of the wide range of garden roses. Etymology The name ''rose'' comes from L ...

Phragmidium Tuberculatum
''Phragmidium '' is a genus of Rust (fungus), rust fungus that typically infects plant species in the family Rosaceae. It is characterised by having stalked teliospores borne on telium, telia each having a row of four or more cells. All species have a caeoma (fungal anatomy), caeoma which is a diffuse aecidium lacking a peridium. There are a number of species of ''Phragmidium'', most of which are restricted to one or a few host species. Examples include: *''Phragmidium acuminatum'' on ''Rubus saxatile'' *''Phragmidium bulbosum'' on ''Rubus fruticosus'' and ''Rubeus caesius'' *''Phragmidium mucronatum'' *''Phragmidium sterilis'' on ''Potentilla sterilis'' *''Phragmidium potentillae'' on ''Potentilla anglica'' *''Phragmidium rosae-pimpinellifoliae'' *''Phragmidium rubi-idaei'' on raspberry *''Phragmidium tuberculatum'' on some rose cultivars *''Phragmidium violaceum'' on cultivated blackberry and loganberry Possibly the most commonly encountered is ''P. mucronatum'', found on most ...

Raspberry
The raspberry is the edible fruit of a multitude of plant species in the genus ''Rubus'' of the rose family, most of which are in the subgenus '' Idaeobatus''. The name also applies to these plants themselves. Raspberries are perennial with woody stems. World production of raspberries in 2020 was 895,771 tonnes, led by Russia with 20% of the total. Description A raspberry is an aggregate fruit, developing from the numerous distinct carpels of a single flower. What distinguishes the raspberry from its blackberry relatives is whether or not the torus ( receptacle or stem) "picks with" (i.e., stays with) the fruit. When picking a blackberry fruit, the torus stays with the fruit. With a raspberry, the torus remains on the plant, leaving a hollow core in the raspberry fruit. Raspberries are grown for the fresh fruit market and for commercial processing into individually quick frozen (IQF) fruit, purée, juice, or as dried fruit used in a variety of grocery products such as raspb ...
