Vine Especies Flashcards
Viticulture, The Vine, Vitis, The Rootstock, WSET L4 DIPLOMA
Talk about Vitis vinifera.
- survived the quartenary ice ages in Europa.
- variable vigour.
- variable ripening period.
- adapted to many soil types.
- NOT resistance to phylloxera.
Talk about Vitis vinifera sativa.
- subspecies of Vitis vinifera.
- the cultivated vine.
- with 5-10.000 wine-producing varieties.
- for good fruit set it is selected to be hermaphroditic.
Talk about Vitis vinifera silvestris.
- subspecies of Vitis vinifera.
- wild European vines.
- are not usually hermaphrodite.
- the ancestors of all modern grape varieties.
- mostly eliminated by phylloxera.
Talk about Vitis labrusca.
- north eastern USA.
- strongly flavoured, dark berries.
- foxied aromas
- common parent in American hybrids such as Concord.
- not often used for rootstock production.
Talk about Vitis riparia.
- found on river banks and alluvial soil in the central-eastern parts of North America.
- Principally used for rootstock production.
- low vigour.
- low surface rooting
- encourage early ripening.
- good resistance to phylloxera.
- to suffer from iron deficiency (chlorosis) in chalk soils.
- used to control vigour in highly fertile soils.
Talk about Vitis rupestris.
- light soils in the southern centre of the USA.
- used as a rootstock.
- it is vigorous, with a deep rooting system.
- good resistance to phylloxera.
- very susceptible to chlorosis.
- well adapted in poor soils with limited water availability.
Talk about Vitis berlandieri.
- chalky slopes in the southern USA and Mexico.
- used as a rootstock.
- it is vigorous, with a deep rooting system.
- high resistance to chlorosis.
- rarely it is used as a pure species because its cuttings have a very poor ability to root.
Often it is hybridised with:
- riparia: to produce lime-resistant rootstocks that graft;
- rupestris: to produce root easily different level of vigour.
What is the other way in which the name Vitis vinifera is often written?
V. vinifera.
Which family belongs to species V. vinifera?
