Using geographic information system (GIS) to define some indicators at climate and soil level of Primitivo wine
The old world and the new world wine-making philosophies tried to explain wine quality with role of nature and organoleptic characteristics of the wine (Parodi, 1997).
Determination of YLOID in soil and grapevine system (Vitis vinifera L.) by ICP-MS technique: A hopeful proxy for the geographical characterization of food products? A validation study with different varieties and rootstocks
The rising importance given from legislators and consumers to provenance of food purchased and/or eaten, in last years motivated several researches to identification of the geographical origin of food.
Increase of detail in soil surveys and its contribution for managing wine quality in Vale dos Vinhedos, Brazil
Information on soils is becoming more and more important for viticulture since several factors that influence grape and wine quality are related to soil properties.
Bioaccumulation of major and trace elements in leaves and grapes in a vineyard site of La Mancha region
Three different plot soils in a vineyard were characterized. The soils belonged to the Luvisol and Cambisol groups. In each case, major and trace element contents were determined in topsoil, leaf and grape samples.
Water retention properties of an acidic vineyard soil modified by sugar foam liming
Soil pH is one of the most important factors that influences the use of a particular soil for Viticulture. An acidic vineyard soil is usually amended before planting to raise the pH.
Arsenic in soil and grapes and changes in elemental content during winemaking
Healthiness is a prerequisite for all agricultural products, foods and beverages. The presence of arsenic (As) in these products creates concern, due to its carcinogenicity.
Factors affecting berry composition of Tempranillo grapevines before the arrest of phloem transport
It is already known that berry ripening is determined by the leaf area/fruit ratio, as well as temperature and leaf physiology. The aim of this work was to assess the influence of these parameters on Tempranillo cultivar throughout stage III of berry development.
Berry size and maturity affect phenolic extraction into Pinot noir wines
Berry skin and seeds differ in their phenolic content, structure and accumulation dynamics during maturation. Therefore a change in berry size or maturity level may affect their contribution to wine composition.
Grapevine yield variability: contribution of grape load and effects of the previous season’s growing conditions
The grapevine yield may be highly variable over years, even in the same plot with the same cultural practices.
Agronomic performances of biodegradable films as an alternative to polyethylene mulches in vineyards
The use of polyethylene (PE) mulch at planting ensures the successful and homogeneous establishment of vineyards and also leads them to produce one year earlier.
The microvine provides new perspectives for research on berry physiology
The berry developmental cycle was studied in a microvine parental line (L1) as well as in a segregating population of 130 genotypes (microvine x ugni blanc).
Anthocyanins, flavonols and flavanols of Vitis vinifera L. cv Syrah wines as affected by row orientation and ripeness levels
In this study results of the effect of different row orientations and ripeness levels on the wine chemical composition of Syrah (Vitis vinifera L.) are presented.
Effect of early leaf removal on yield components, must composition and wine volatiles of Loureira cv. from north-west Spain
Yield management is a key technique in modern viticulture and is widely recognized as an important factor in the composition of resultant wines.
Effect of leaf removal on composition in Vitis vinifera L. cv. Tempranillo wine in Extremadura (Spain)
Early leaf removal is a management technique applied to regulate crop load and improve fruit microclimate conditions in vigorous vineyards, increasing aeration and sunlight exposure in the cluster zone.
Consequences of leaf removal on canopy structure, yield and fruit composition of Touriga Nacional grapevines
Defoliation is one of the canopy management operations used as a technic to reduce the leaf area and, consequently, to contribute to improve production.
Alternatives to bunch thinning in yield control and its effects on quality of the grapes and wine composition in cv. Baga (Vitis vinifera L.)
Excessive yield and frequency of some diseases are strongly correlated, so yield control is an important current issue.
First evaluation of the influence of leaf removal on the vegetative and reproductive characteristics of grapevine cv. Nero d’Avola (Vitis vinifera L.) grown under semi-arid conditions
Among vineyard management techniques, leaf removal allows modifying the vegetative characteristics of the vines and the micro-climate of the grape clusters.
Leaf removal treatments as affecting Botrytis cinerea occurrence on Pinot gris grapes from north-eastern Italy: results over four years of trials
Fruit-zone leaf removal is a technique applied in the vineyards aiming to improve cluster microclimate thus allowing the grapes to achieve better quality and cluster sanity.
Effects of timing and intensity of basal leaf removal in cv. Sauvignon
Leaf removal has been the subject of several studies, many of them in order to know the best time and intensity in order to promote yield and quality of the grapes.
Interaction “training system x cluster thinning”: effects on yield and quality, cv. Baga, in Bairrada region
During the growing season of 2007, in Bairrada region, were compared the effects of the training system and cluster thinning on the agronomic and ecophysiological behaviour of the Portuguese red variety Baga, grafted onto 3309C rootstock.
