Botryotinia
''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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Botrytis Cinerea
''Botrytis cinerea'' is a necrotrophic fungus that affects many plant species, although its most notable hosts may be wine grapes. In viticulture, it is commonly known as "botrytis bunch rot"; in horticulture, it is usually called "grey mould" or "gray mold". The fungus gives rise to two different kinds of infections on grapes. The first, grey rot, is the result of consistently wet or humid conditions, and typically results in the loss of the affected bunches. The second, noble rot, occurs when drier conditions follow wetter, and can result in distinctive sweet dessert wines, such as Sauternes (wine), Sauternes or the Aszú of Tokaji/Grasă de Cotnari. The species name ''Botrytis cinerea'' is derived from the Latin for "grapes like ashes"; although poetic, the "grapes" refers to the bunching of the fungal spores on their Conidium, conidiophores, and "ashes" just refers to the greyish colour of the spores ''en masse''. The fungus is usually referred to by its anamorph (asexual form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. In the stored cro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''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, ''N. pseudonarcissus''. narcissus, and jonquil are used to describe all or some 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. ''Narcissus'' were well known in ancient civilisation, both medicinally and botanically, but formally described by Carl Linnaeus, Linnaeus in his ''Species Plantarum'' (1753). The genus ...

Tulip
Tulips (''Tulipa'') are a genus of spring-blooming perennial herbaceous bulbiferous geophytes (having bulbs as storage organs). The flowers are usually large, showy and brightly coloured, generally red, pink, yellow, or white (usually in warm colours). They often have a different coloured blotch at the base of the tepals (petals and sepals, collectively), 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 originally were found in a band stretching from Southern Europe to Ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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; it results 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. Some plants produce varying numbers of seeds that lack embryos; these are empty seeds which never germinate. Dormant seeds are viable seeds that do ...

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 |
