Botryotinia Fuckeliana
''Botryotinia'' is a genus of ascomycete fungi causing several plant diseases. The anamorphs of ''Botryotinia'' are mostly included in the " imperfect fungi" genus ''Botrytis''. The genus contains 22 species and one hybrid. Plant diseases caused by ''Botryotinia'' species appear primarily as blossom blights and fruit rots but also as leaf spots and bulb rots in the field and in stored products. The fungi induce host cell death resulting in progressive decay of infected plant tissue, whence they take nutrients. Sexual reproduction takes place with ascospores produced in apothecia, conidia are the means of asexual reproduction. Sclerotia of plano-convexoid shape are typical. Some species also cause damping off, killing seeds or seedlings during or before germination. '' Botryotinia fuckeliana'' (or its anamorph ''Botrytis cinerea'') is an important species for wine industry as well as horticulture. Other economically important species include '' Botryotinia convoluta'' (the type ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Germination
Germination is the process by which an organism grows from a seed or spore. The term is applied to the sprouting of a seedling from a seed of an angiosperm or gymnosperm, the growth of a sporeling from a spore, such as the spores of fungi, ferns, bacteria, and the growth of the pollen tube from the pollen grain of a seed plant. Seed plants Germination is usually the growth of a plant contained within a seed resulting in the formation of the seedling. It is also the process of reactivation of metabolic machinery of the seed resulting in the emergence of radicle and plumule. The seed of a vascular plant is a small package produced in a fruit or cone after the union of male and female reproductive cells. All fully developed seeds contain an embryo and, in most plant species some store of food reserves, wrapped in a seed coat. Dormant seeds are viable seeds that do not germinate because they require specific internal or environmental stimuli to resume growth. Und ...

Narcissus (plant)
''Narcissus'' is a genus of predominantly spring flowering perennial plant, perennial plants of the amaryllis family, Amaryllidaceae. Various common names including daffodil,The word "daffodil" is also applied to related genera such as ''Sternbergia'', ''Ismene (plant), Ismene'', and ''Fritillaria meleagris''. It has been suggested that the word "Daffodil" be restricted to the wild species of the British Isles, ''Narcissus pseudonarcissus, N. pseudonarcissus''. narcissus (plural narcissi), and jonquil, are used to describe some or all members of the genus. ''Narcissus'' has conspicuous flowers with six petal-like tepals surmounted by a cup- or trumpet-shaped Corona (plant structure), corona. The flowers are generally white and yellow (also orange or pink in garden varieties), with either uniform or contrasting coloured tepals and corona. ''Narcissi'' were well known in ancient civilisation, both medicinally and botanically, but were formally described by Carl Linnaeus, Lin ...

Tulip
Tulips are spring-blooming perennial herbaceous bulbiferous geophytes in the ''Tulipa'' genus. Their flowers are usually large, showy, and brightly coloured, generally red, orange, pink, yellow, or white. They often have a different coloured blotch at the base of the tepals, internally. Because of a degree of variability within the populations and a long history of cultivation, classification has been complex and controversial. The tulip is a member of the lily family, Liliaceae, along with 14 other genera, where it is most closely related to '' Amana'', ''Erythronium'', and '' Gagea'' in the tribe Lilieae. There are about 75 species, and these are divided among four subgenera. The name "tulip" is thought to be derived from a Persian word for turban, which it may have been thought to resemble by those who discovered it. Tulips were originally found in a band stretching from Southern Europe to Central Asia, but since the seventeenth century have become widely naturalise ...

Botrytis Fabae
''Botrytis fabae'' is a plant pathogen, a fungus that causes chocolate spot disease of broad or fava bean plants, ''Vicia faba''. It was described scientifically by Mexican-born Galician microbiologist Juan Rodríguez Sardiña in 1929. Symptoms Chocolate spot disease caused by ''Botrytis fabae'' manifests itself as small red-brown spots on leaves, stems and flowers of broad bean plants. These enlarge and develop a grey, dead centre with a reddish-brown margin. Spores form on the dead tissue and spread the infection to other plants. In severe infections leaves and flowers may fall and badly affected stems may keel over.Government of Western Australia Life cycle The pathogen survives as |
Botrytis Allii
''Botrytis allii'' is a plant pathogen, a fungus that causes neck rot in stored onions ('' Allium cepa'') and related crops. Its teleomorph is unknown, but other species of '' Botrytis'' are anamorphs of '' Botryotinia'' species. The species was first described scientifically by Mancel Thornton Munn in 1917. Biology There are seven different species of ''Botrytis'' associated with onions in storage, but the rot induced by ''B. allii'' and ''B. aclada'' causes the greatest commercial loss. The two can be distinguished microscopically; the conidia of ''B. allii'' have a maximum length of 15 μm and mean size of 10.2 × 5.7 μm, while the conidia of ''B. aclada'' have a maximum length of 12 μm and mean size of 8.6 × 4.6 μm. The infection is present in the field but does not manifest itself until after harvest, however there may be a falling off of vigour while the crop is still growing, particularly in cool, moist weather.

Botryotinia Polyblastis
''Botryotinia polyblastis'' is a fungal plant pathogen that causes Narcissus Fire of daffodils, genus '' Narcissus''. Host and symptoms ''Botryotinia polyblastis'' is known to attack ornamental plants of the genus ''Narcissus''. Plants in this genus are commonly known as daffodils, paper whites and jonquils. ''Botryotinia polyblastis'' generally attacks its host in three stages beginning with the flower and ending with an infection of the leaves. The disease first infects the flower through water soaked areas on petals and causes those petals to brown, wither and die. The disease then causes the formation of elliptical-shaped, tan leaf spots appear on the tips of the hosts leaves. The leaf spots typically start off small and can eventually grow to be greater than 5mm in length. Shortly after the appearance of leaf spots the leaves begin to exhibit chlorosis. Once the plant has lost the majority of its leaves to ''Botryotinia polyblastis'' the plant can no longer photosynthesize ...

Type Species
In International_Code_of_Zoological_Nomenclature, zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological Type (biology), type wiktionary:en:specimen, specimen (or specimens). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the International Code of Nomenclature for algae, fungi, and plants, code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name with that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have suc ...

Wine
Wine is an alcoholic drink made from Fermentation in winemaking, fermented fruit. Yeast in winemaking, Yeast consumes the sugar in the fruit and converts it to ethanol and carbon dioxide, releasing heat in the process. Wine is most often made from grapes, and the term "wine" generally refers to grape wine when used without any qualification. Even so, wine can be made fruit wine, from a variety of fruit crops, including plum, cherry, pomegranate, blueberry, Ribes, currant, and Sambucus, elderberry. Different varieties of grapes and Strain (biology), strains of yeasts are major factors in different styles of wine. These differences result from the complex interactions between the Biochemistry, biochemical development of the grape, the reactions involved in fermentation, the grape's growing environment (terroir), and the wine production process. Many countries enact legal appellations intended to define styles and qualities of wine. These typically restrict the geographical origin ...
