Vitis Acerifolia
''Vitis acerifolia'' is a species of grape native to the south-central part of the Great Plains of the United States (Kansas, Oklahoma, northern Texas, eastern Colorado, and northeastern New Mexico).Great Plains Flora Association. 1986. Fl. Great Plains i–vii, 1–1392. University Press of Kansas, Lawrence Its leaf shape is the origin of its name, which is Latin for maple-leaf grape, but it is widely referenced in literature by the synonym, ''Vitis longii''. Cultivation and uses ''Vitis acerifolia'' provides many potential benefits for the breeding of hybrid grapes. ''Vitis acerifolia'' is second in cold-hardiness among grapes only to ''Vitis riparia''. Unlike other cold hardy grapes, it will grow long into fall if weather is clement, but can harden off remarkably fast in a cold snap. This makes it ideally suited for North American winter weather which often include sudden fluctuations in temperature, and is superior in this regard to its rival for second place in cold hardine ...

Caprock Canyons State Park And Trailway
Caprock Canyons State Park and Trailway is a Texas state park located along the eastern edge of the Llano Estacado in Briscoe County, Texas, United States, approximately southeast of Amarillo. The state park opened in 1982 and is in size, making it the third-largest state park in Texas. Recreation In 1993, a hiking, biking, and equestrian rail trail opened that stretches through the park through Floyd, Briscoe, and Hall counties. The trailway was created after the Texas Parks and Wildlife Department acquired of right-of-way from the abandoned Fort Worth and Denver Railroad's lines between Estelline and South Plains.

Hardiness (plants)
Hardiness of plants describes their ability to survive adverse growing conditions. It is usually limited to discussions of climatic adversity. Thus a plant's ability to tolerate cold, heat, drought, flooding, or wind are typically considered measurements of hardiness. Hardiness of plants is defined by their native extent's geographic location: longitude, latitude and elevation. These attributes are often simplified to a hardiness zone. In temperate latitudes, the term most often describes resistance to cold, or "cold-hardiness", and is generally measured by the lowest temperature a plant can withstand. Hardiness of a plant is usually divided into two categories: tender, and hardy. (Some sources also use the erroneous terms "Half-hardy" or "Fully hardy".) Tender plants are those killed by freezing temperatures, while hardy plants survive freezing—at least down to certain temperatures, depending on the plant. "Half-hardy" is a term used sometimes in horticulture to describe bed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Described In 1830
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ability ...

Glassy-winged Sharpshooter
The glassy-winged sharpshooter (''Homalodisca vitripennis'', formerly known as ''H. coagulata'') is a large leafhopper (family Cicadellidae), similar to other species of sharpshooter. Description These sharpshooters are about in length. Their color is dark brown to black with black-and-yellow undersides, with yellow eyes, and the upper parts of the head and back are speckled with ivory or yellowish spots. The wings are transparent with reddish veins.APHIS. 2002Glassy-winged Sharpshooter and Pierce's Disease in California They have piercing, sucking mouthparts and rows of fine spines on their hind legs. Distribution It is native to North America (northeastern Mexico), but it was accidentally introduced into Southern California in the early 1990s, probably with ornamental or agricultural stock. There it has become an agricultural pest especially to viticulture. Glassy-winged sharpshooters usually lay a mass of eggs on the underside of leaves, and they cover them with powdery ...

Xylella Fastidiosa
''Xylella fastidiosa'' is an aerobic, Gram-negative bacterium, Gram-negative bacterium of the genus ''Xylella''. It is a plant pathogen, that grows in the water transport tissues of plants (Xylem, xylem vessels) and is transmitted exclusively by xylem sap-feeding insects such as Sharpshooter (insect), sharpshooters and Aphrophoridae, spittlebugs. Many plant diseases are due to infections of ''X. fastidiosa'', including bacterial leaf scorch, oleander leaf scorch, coffee leaf scorch (CLS), alfalfa dwarf, phony peach disease, and the economically important Pierce's disease of grapes (PD), olive quick decline syndrome (OQDS), and citrus variegated chlorosis (CVC). While the largest outbreaks of ''X. fastidiosa''–related diseases have occurred in the Americas and Europe, this pathogen has also been found in Taiwan, Israel, and a few other countries worldwide. ''Xylella fastidiosa'' can infect an extremely wide range of plants, many of which do not show any symptoms of disease. Dise ...

Anthocyanin
Anthocyanins (), also called anthocyans, are water-soluble vacuolar pigments that, depending on their pH, may appear red, purple, blue, or black. In 1835, the German pharmacist Ludwig Clamor Marquart gave the name Anthokyan to a chemical compound that gives flowers a blue color for the first time in his treatise "''Die Farben der Blüthen''". Food plants rich in anthocyanins include the blueberry, raspberry, black rice, and black soybean, among many others that are red, blue, purple, or black. Some of the colors of autumn leaves are derived from anthocyanins. Anthocyanins belong to a parent class of molecules called flavonoids synthesized via the phenylpropanoid pathway. They occur in all tissues of higher plants, including leaves, stems, roots, flowers, and fruits. Anthocyanins are derived from anthocyanidins by adding sugars. They are odorless and moderately astringent. Although approved as food and beverage colorant in the European Union, anthocyanins are not approved ...

Blackcurrant
The blackcurrant (''Ribes nigrum''), also known as black currant or cassis, is a deciduous shrub in the family Grossulariaceae grown for its edible berries. It is native to temperate parts of central and northern Europe and northern Asia, where it prefers damp fertile soils. It is widely cultivated both commercially and domestically. It is winter hardy, but cold weather at flowering time during the spring may reduce the size of the crop. Bunches of small, glossy black fruit develop along the stems in the summer and can be harvested by hand or by machine. Breeding is common in Scotland, Poland, Lithuania, Latvia, Norway, and New Zealand to produce fruit with better eating qualities and bushes with greater hardiness and disease resistance. The raw fruit is particularly rich in vitamin C and polyphenols. Blackcurrants can be eaten raw but are usually cooked in sweet or savoury dishes. They are used to make jams, preserves, and syrups and are grown commercially for the juice mar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Labrusca
''Vitis labrusca'', the fox grape, is a species of grapevines belonging to the ''Vitis'' genus in the flowering plant family Vitaceae. The vines are native to eastern North America and are the source of many grape cultivars, including Catawba, Concord, Delaware, Isabella, Niagara, and many hybrid grape varieties such as Agawam, Alexander and Onaka. Among the characteristics of this vine species in contrast to the European wine grape ''Vitis vinifera'' are its "slip-skin" that allows the skin of the grape berries to easily slip off when squeezed, instead of crushing the pulp, and the presence of tendrils on every node of the cane. Another contrast with European ''vinifera'' is the characteristic "foxy" musk of ''V. labrusca'', best known to most people through the Concord grape. Jancis Robinson (ed.) ''The Oxford Companion to Wine'' (Oxford University Press, third edition 2006, ), pp 19-20 This musk is not related to the mammalian fox, but rather to the strong, earthy aromas cha ...

Phylloxera
Grape phylloxera is an insect pest of commercial grapevines worldwide, originally native to eastern North America. Grape phylloxera (''Daktulosphaira vitifoliae'' (Fitch 1855) belong to the family Phylloxeridae, within the order Hemiptera, bugs); originally described in France as ''Phylloxera vastatrix''; equated to the previously described ''Daktulosphaera vitifoliae'', ''Phylloxera vitifoliae''. The insect is commonly just called phylloxera (; from grc, φύλλον, leaf, and , dry). These almost microscopic, pale yellow sap-sucking insects, related to aphids, feed on the roots and leaves of grapevines (depending on the phylloxera genetic strain). On ''Vitis vinifera'', the resulting deformations on roots ("nodosities" and "tuberosities") and secondary fungal infections can girdle roots, gradually cutting off the flow of nutrients and water to the vine.Wine & Spirits Education Trust ''"Wine and Spirits: Understanding Wine Quality"'' pgs 2-5, Second Revised Edition (2012), Lo ...

Vitis Amurensis
''Vitis amurensis'', the Amur grape, is a species of grape native to the Asian continent. Its name comes from the Amur Valley in Russia and China. It is very resistant to frost, but is not tolerant to drought. Selections vary, but as a species it has strong resistance to anthracnose and ripe rot, and moderately strong resistance to downy mildew and powdery mildew. Botanical description A vine with stem 5–10 cm in diameter and typically spreading to 15–18 m, rarely up to 20–25 meters. Tendrils capable of wrapping around things will entwine the branches of neighbouring plants or anything else they can use for support. The bark is dark, scaly and with vertical stripes on old shoots. Young shoots are green, often with a reddish hue, reddish-brown in autumn. The leaves vary greatly in shape. They can be solid, three- or five-lobed, ovate or rounded, arched at the base. The size ranges from 9 to 25 cm with sharp edges and rounded-triangular serrate teeth. The surf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vitis Riparia
''Vitis riparia'' Michx, with common names riverbank grape or frost grape, is a vine indigenous to North America. As a climbing or trailing vine, it is widely distributed across central and eastern Canada and the central and northeastern parts of the United States, from Quebec to Texas, and eastern Montana to Nova Scotia. There are reports of isolated populations in the northwestern USA, but these are probably naturalized. It is long-lived and capable of reaching into the upper canopy of the tallest trees. It produces dark fruit that are appealing to both birds and people, and has been used extensively in commercial viticulture as grafted rootstock and in hybrid grape breeding programs. ''Riverbank grape'' is a translation of the scientific name ''Vitis riparia''; means "of riverbanks" in Latin, deriving from "riverbank". Description Mature vines have loose, fissured bark, and may attain several inches in diameter. Leaves are alternate, often with opposite tendrils or infl ...
