Grapevine fanleaf virusGrapevine fanleaf virus (GFLV) is a plant pathogenic virus of the family Secoviridae. It infects grapevines, causing chlorosis of the leaves and lowering the fruit quality. Because of its effect on grape yield, GFLV is a pathogen of commercial importance. It is transmitted via a nematode vector, Xiphinema index. This nematode acquires the virus through feeding on roots of an infected plant, and passes it on in the same manner. Host and Symptoms: The host for Grapevine fanleaf virus or GFLV is the vitis species.
AligotéAligoté is a white grape used to make dry white wines, especially in the Burgundy region of France where it was first recorded in the 18th century. Since it is tolerant to cold, this variety is also cultivated in Eastern European countries. In 2004, it was the 22nd most planted vine variety in the world at 45,000 hectares (110,000 acres). Aligoté is used to produce a varietal white wine, and is sometimes included in the blend of Burgundian sparkling wine known as Crémant de Bourgogne.
Sauternes (wine)Sauternes is a French sweet wine from the region of the same name in the Graves section in Bordeaux. Sauternes wine is made from Sémillon, sauvignon blanc, and muscadelle grapes that have been affected by Botrytis cinerea, also known as noble rot. This causes the grapes to become partially raisined, resulting in concentrated and distinctively flavored wines. Due to its climate, Sauternes is one of the few wine regions where infection with noble rot is a frequent occurrence.
Phoenicians and wineThe culture of the ancient Phoenicians was one of the first to have had a significant effect on the history of wine. Phoenicia was a civilization centered in current day Lebanon. Between 1550 BC and 300 BC, the Phoenicians developed a maritime trading culture that expanded their influence from the Levant to North Africa, the Greek Isles, Sicily, and the Iberian Peninsula. Through contact and trade, they spread not only their alphabet but also their knowledge of viticulture and winemaking, including the propagation of several ancestral varieties of the Vitis vinifera species of wine grapes.
AmpelographyAmpelography (ἄμπελος, "vine" + γράφος, "writing") is the field of botany concerned with the identification and classification of grapevines, Vitis spp. Traditionally this has been done by comparing the shape and colour of the vine leaves and grape berries; more recently the study of vines has been revolutionised by DNA fingerprinting. The grape vine is an extremely variable species and some , such as Pinot, mutate particularly frequently.
Agriculture in ancient RomeRoman agriculture describes the farming practices of ancient Rome, during a period of over 1000 years. From humble beginnings, the Roman Republic (509 BC to 27 BC) and the Roman Empire (27 BC to 476 AD) expanded to rule much of Europe, northern Africa, and the Middle East and thus comprised many agricultural environments of which the Mediterranean climate of dry, hot summers and cool, rainy winter was the most common. Within the Mediterranean area, a triad of crops were most important: grains, olives, and grapes.
