Skin and seed phenolic composition of merlot grapes according to different status of water constraint
During 2005 and 2006, different irrigation treatments were assayed in a vineyard to assess the effect of water constraint on the phenolic composition of the skins and the seeds of Merlot grapes; specifically 5 treatments with different levels of water constraint.
Shifts in vineyard weed seed bank composition in response to organic and conventional weed control practices
The aim of this research was to compare the organic weed control practice, soil cultivation, to the conventional practice, applications of the herbicide, glyphosate, in terms of their effects on weed seed bank in a vineyard system.
Riesling terroir in Ontario vineyards: the roles of soil texture, vine size and vine water status
Vine size and soil texture effects on yield components; soil, vine tissue, and fruit composition, and; wine sensory attributes were measured in an Ontario Riesling vineyard in 1998 to 2002 to elucidate the potential basis for terroir.
Research in the technical, socio-economical, and ethical aspects for Veneto vitivinicolture (North East Italy)
Following the publication of the proceedings of the GESCO (Groupe d’Etude des Systemes de Conduite de la vigne) acts in 2007, this work illustrates the research of the most significant vitivinicultural basins of the North Italy (Cargnello G. et al. 2001).
Relationship between soil water content and vine water status: use of water indicators to irrigate
A study has been carried out along 2005-2007 in order to evaluate the soil water content and the variation of Tempranillo vineyard water status, based on the application of different moderate irrigation doses on two different plant densities, in the Spanish Duero river Valley.
Qualitative and productive response of Albariño to soil management techniques in Rosal (Galicia), North West of Spain
Soil Management techniques (SMT) are reported as useful tools to control plant vigour, productive performance, and qualitative characteristics of the must, particularly in humid areas.
Pruning system in Cabernet-Sauvignon and Merlot: from guyot to spur cordon
The aim of this study is to evaluate physiological behavior of two grapevine varieties, Cabernet Sauvignon and Merlot pruned both as spur cordon and Guyot.
Pruning system affects fruit yield, grape and wine composition of Primitivo variety, grown in a warm area of Southern Italy
The objective of this research was to compare three pruning systems, with same buds load, in term of their impact on vine performance and wine composition of Primitivo (Vitis vinifera L.) in the Apulia region, Southern Italy.
Progression of Sauvignon blanc (Vitis vinifera L.) ripening for two regions of the western cape coastal area of South Africa: preliminary results on berry colour, malic acid and sucrose evolution in relation to temperature
According to recent studies on climatic change in the South African vineyards, observations have shown that frequency of warm years is clearly increasing in the various wine producing regions of the Western Cape since the 1980’s.
Preliminary results on Nero Di Troia winegrape mechanical pruning
Traditional winter pruning is labor consuming and has a high cost for grape-growing farms.
Preliminary investigations on sunburn in Chardonnay grapevine variety
The aim of this investigation was to determine if a temperature response curve can be used to describe sunburn in grape berries.
Prediction of a white wine aromatic potential by infrared spectroscopic measurements on grapes at harvest
The aromatic sensing of Colombard wine produced in the Gascony vineyard, mainly comes from two varietal thiols: 3-mercaptohexan-1-ol (3MH) and 3-mercaptohexylacetate (3MHA).
Practices of yield reduction: effects on grape composition of Sangiovese
Canopy management practices such as cluster thinning are considered efficient tools for controlling the crop load and thereby fruit and wine quality.
Possibilities to reduce the velocity of berry maturation through various leaf area to fruit ratio modifications in Vitis vinifera L. Riesling
Trends of recent warming have advanced the phenological development of many crops.

This work reports the results of one field campaign aimed 10 evaluate the physiological responses and berry composition of ‘Aleatico’ grapevine subjected to non irrigated condilion and irrigation under moderate water deficit.
Physiological behaviour and leaf development assessment of cv. Tempranillo with three plant densities in the Duero River Valley (Spain)
The knowledge of the influence that plant density has on the agronomic grapevine behaviour and on the leaf development of a vineyard becomes
Physiological alterations in Esca diseased vines
The aim of the study was to evaluate the eficiency of grapevine plants affected by esca proper,a destructive disease in many grape production countries.
Phenological, yield, and fruit maturation responses of merlot grapevines to timing of winter pruning
The phenological, yield, and fruit maturation responses of Merlot grapevines to timing of pruning were evaluated in a commercial vineyard in Rutherford, California.
