Crop load is more effective than canopy density in influencing grape berry and wine composition of Montepulciano (Vitis vinifera L.)
Four summer pruning techniques (shoot thinning at anthesis, pre- anthesis removal of the basal leaves and laterals of the main shoot, pre-veraison removal of the basal laterals of the shoot
Experience of leaf removal on Vitis vinifera L. ‘Cannonau’ in Sardinia
During 2009 and 2010 an experiment of leaf removal on ‘Cannonau’ was conducted in North Sardinia with the aim of evaluating how this technique influences microclimate and berry quality.
The “peppery” sesquiterpene rotundone increases rapidly post-veraison in Vitis vinifera L. Syrah berries
Syrah is becoming more important in the Australian and New Zealand wine industry, largely due to distinct black pepper characters in the commercial wines.
Effect of rootstocks on some parameters of must, yield and colour leaf of cv. Marzemino during year 2010 in Trentino
In this work a comparison between rootstocks (Kober 5BB, Teleky 5C, SO4, 420A, 101-14 and Schwarzmann) used for the cv Marzemino in Trentino (Nord-East Italy) was performed.
It is possible through canopy management to control high pH levels of Tannat grapes and wines
One of the main problems affecting Tannat’s wine quality in Uruguay concerns pH levels.
French ‘Tannat’ clones’ performance in Southern Uruguay
Tannat is the main red wine variety planted in Uruguay. Introduced from France at the end of the nineteenth-century, hastily was established in the country, accounting nowadays almost 30% of the vineyard area.
Microclimatic aspects in vineyards with different vigour and exposure
A microclimatic characterization of differently exposed vineyard was carried out.
Effect of artificial shading on polyphenolic accumulation and aromatic composition of Grillo cv (Vitis vinifera L.)
This study was carried out in 2009 in a commercial vineyard
V. vinifera L. cv. Grillo.
Relation between row and leaf orientation of Syrah/101-14 Mgt
Row orientation may have a determining effect on terroir valorization, mainly because of its effect on the total amount of sunlight energy being intercepted.
Factors involved in abnormal graft union development
The purpose of the project is to provide answers on the likely factors involved in the incidence (origin and prevention) of the phenomenon of abnormal graft union enlargement (graft union increase and retarded rootstock development).
Merlot wine quality as affected by crop level
Three crop levels of cv. Merlot (Vitis vinifera L.) were evaluated in this study in order to assess the impact of crop level on cv. Merlot yield components and wine quality.
Post-veraison trimming practices for slowing down berry sugar accumulation and tuning technological and phenolic maturity
In the last years, particularly in the viticultural areas characterized by low soil fertility and water availability, when the skin berry colour of red-varieties is considered optimal for harvest,
Effect of early leaf removal on yield and quality of must and wine in the white cv. Loureiro (Vitis vinifera L.) – Vinhos Verdes Region
Several work of research had been done in Portugal in the last years about bunch thinning in order to achieve yield control, and a consequent improvement in quality parameters
Mechanical pruning on a vertical shoot positioning system in Dão region
With the objective of costs reduction in winter pruning, a trial field was conducted from 2008 to 2010 to compare mechanical pruning (MEC = hedge pruning) with manual pruning (MAN),
Delaying berry ripening process through leaf area to fruit ratio decrease
The viticulture practices have always been focused on the production of grapes with higher sugar level, and this tendency has been emphasized by the climate change.
Determination of the performance of different grape varieties grafted onto 110 R rootstock
This research was caried out to determine suitable grape varieties that can be grown in the Sanliurfa province in the Ziyaeddin Akbulut nursery garden in Turkey.
Ten years comparison (1999-2009) of seven high density training systems for the Sagrantino cultivar
With the aim to evaluate the role of training systems on vegetative-productive behavior of the cv Sagrantino an experimental vineyard with seven high density training systems was created
Role of leaf removal on grape quality of Sauvignon and Grechetto cultivars in Umbria
The shading of the productive belt produces clusters with
minor sugar contents and higher acidity.
Risk of late frost events in viticulture – temperature trends, phenological observations and spatial analysis based on digital terrain models in Franconia/Germany
In the course of global warming a general decrease of frost days per year and in spring can be stated. However, in viticulture this matter of fact doesn´t lead to a reduction of the risk of damages to grapevines by late spring frost events.
Impact of leaf to fruit ratio on grape composition in Merlot grapevines
Adjustments of viticultural practices are required to adapt to climate change. In particular, vineyard management that vary the fruit to leaf area ratio is an important option to maintain and enhance fruit quality.
