Black Knot
''Dibotryon morbosum'' or ''Apiosporina morbosa'' is a plant pathogen, which is the causal agent of black knot. It affects members of the ''Prunus'' genus such as cherry, plum, apricot, and chokecherry trees in North America. The disease produces rough, black growths that encircle and kill the infested parts, and provide habitat for insects. The disease was first described in 1821 in Pennsylvania, but has spread across North America. While it was one of the most destructive diseases of plum and cherry trees in the late 19th century, today it is relatively well controlled in many cultivated areas and seen primarily in poorly managed orchards, or where strongly established, including in the wild. Many urban centres in North America have black knot control programs. Black knot occurs only on the woody parts of trees, primarily on twigs and branches, but can spread to larger limbs and even the trunk. Olive-green swellings from the disease are visible in the late spring; as it sprea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schwein
Schwein (German for ''pig'' as well as ''pork'') is a music group comprising members of Buck-Tick, KMFDM, and Pig. Members Raymond Watts (PIG; vocals, programming, guitar) and Hisashi Imai (Buck-Tick; guitar and noise), both having worked together in Schaft, were joined by Atsushi Sakurai (Buck-Tick; vocals), Sascha Konietzko (KMFDM; vocals and programming) and Lucia Cifarelli (KMFDM; vocals). In 2001 Schwein released an album, ''Schweinstein'', which peaked at number 18 on Oricon's album chart, followed by the remix album ''Son of Schweinstein''. Schwein toured Japan in the summer of 2001. However, Konietzko did not tour with them, citing illness and a desire to focus on KMFDM. In a 2023 interview with ''Visual Music Japan'', Raymond Watts talked about the project and cited Schwein as his favorite collaboration to date and called Sakurai a "grand vocalist".

Prunus Domestica
''Prunus domestica'' is a species of flowering plant in the family Rosaceae. A deciduous tree, it includes many varieties of the fruit trees known as plums in English, though not all plums belong to this species. The greengages and damsons also belong to subspecies of ''P. domestica''. Description It typically forms a large shrub or a small tree. It may be somewhat thorny, with white blossom, borne in early spring. The oval or spherical fruit varies in size, but can be up to across. The pulp is usually sweet, but some varieties are sour. Like all ''Prunus'' fruits, it contains a single large seed, usually called a stone, which is discarded when eating. Taxonomy The species' hybrid parentage was believed to be '' Prunus spinosa'' and '' P. cerasifera''; however, recent cytogenetic evidence seem to implicate 2×, 4×, 6× ''P. cerasifera'' as the sole wild stock from which the cultivated 6× ''P. domestica'' could have evolved.

Fungi Described In 1915
A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as one of the traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or Protozoa and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''true fungi'' or ''Eumycete ...

Stone Fruit Tree Diseases
In geology, rock (or stone) is any naturally occurring solid mass or aggregate of minerals or mineraloid matter. It is categorized by the minerals included, its chemical composition, and the way in which it is formed. Rocks form the Earth's outer solid layer, the crust, and most of its interior, except for the liquid outer core and pockets of magma in the asthenosphere. The study of rocks involves multiple subdisciplines of geology, including petrology and mineralogy. It may be limited to rocks found on Earth, or it may include planetary geology that studies the rocks of other celestial objects. Rocks are usually grouped into three main groups: igneous rocks, sedimentary rocks and metamorphic rocks. Igneous rocks are formed when magma cools in the Earth's crust, or lava cools on the ground surface or the seabed. Sedimentary rocks are formed by diagenesis and lithification of sediments, which in turn are formed by the weathering, transport, and deposition of existing rocks. M ...

Fungicide
Fungicides are pesticides used to kill parasitic fungi or their spores. Fungi can cause serious damage in agriculture, resulting in losses of yield and quality. Fungicides are used both in agriculture and to fight fungal infections in animals, including humans. Fungicides are also used to control oomycetes, which are not taxonomically/genetically fungi, although sharing similar methods of infecting plants. Fungicides can either be contact, translaminar or systemic. Contact fungicides are not taken up into the plant tissue and protect only the plant where the spray is deposited. Translaminar fungicides redistribute the fungicide from the upper, sprayed leaf surface to the lower, unsprayed surface. Systemic fungicides are taken up and redistributed through the xylem vessels. Few fungicides move to all parts of a plant. Some are locally systemic, and some move upward. Most fungicides that can be bought retail are sold in liquid form, the active ingredient being present at 0.08% i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prunus Triloba

Prunus Armeniaca
''Prunus armeniaca'' is the most commonly cultivated apricot species. The native range is somewhat uncertain due to its extensive prehistoric cultivation. Genetic studies indicate Central Asia is the center of origin. It is extensively cultivated in many countries and has escaped into the wild in many places. The specific epithet ''armeniaca'' refers to the country of Armenia in Western Asia. Description ''Prunus armeniaca'' is a small tree, tall, with a trunk up to in diameter and a dense, spreading canopy. The leaves are ovate, long and wide, with a rounded base, a pointed tip and a finely serrated margin. The flowers are in diameter, with five white to pinkish petals; they are produced singly or in pairs in early spring before the leaves. The fruit is a drupe similar to a small peach, diameter (larger in some modern cultivars), from yellow to orange, often tinged red on the side most exposed to the sun; its surface can be smooth (botanically described as: glabrous) ...

Conidium
A conidium ( ; : conidia), sometimes termed an asexual chlamydospore or chlamydoconidium (: chlamydoconidia), is an Asexual reproduction, asexual, non-motility, motile spore of a fungus. The word ''conidium'' comes from the Ancient Greek word for dust, ('). They are also called mitospores due to the way they are generated through the cellular process of mitosis. They are produced exogenously. The two new haploid cells are genetically identical to the haploid parent, and can develop into new organisms if conditions are favorable, and serve in biological dispersal. Asexual reproduction in ascomycetes (the phylum Ascomycota) is by the formation of conidia, which are borne on specialized stalks called conidiophores. The Morphology (biology), morphology of these specialized conidiophores is often distinctive between species and, before the development of molecular techniques at the end of the 20th century, was widely used for identification of (''e.g.'' ''Metarhizium#Species, Metarh ...

Pseudothecia
An ascocarp, or ascoma (: ascomata), is the fruiting body ( sporocarp) of an ascomycete phylum fungus. It consists of very tightly interwoven hyphae and millions of embedded asci, each of which typically contains four to eight ascospores. Ascocarps are most commonly bowl-shaped (apothecia) but may take on a spherical or flask-like form that has a pore opening to release spores (perithecia) or no opening (cleistothecia). Classification The ascocarp is classified according to its placement (in ways not fundamental to the basic taxonomy). It is called ''epigeous'' if it grows above ground, as with the morels, while underground ascocarps, such as truffles, are termed ''hypogeous''. The structure enclosing the hymenium is divided into the types described below (apothecium, cleistothecium, etc.) and this character ''is'' important for the taxonomic classification of the fungus. Apothecia can be relatively large and fleshy, whereas the others are microscopic—about the size of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
