Impact of water status level on abscisic acid and its catabolite profiles in leaves and berries from Bitis sp. Baco noir
To understand the relationship among soil and plant water status, plant physiology and the hormonal profiles associated with it, abscisic acid (ABA) and its catabolites [phaseic acid (PA),
Foliar application of abscisic acid (ABA) to advance fruit ripening and cold acclimation of grapes
The grape and wine industry has been expanding rapidly in north central and eastern U.S. regions and demand for premium wine grapes has also increased.
A leaf gas-exchange model considering leaf nitrogen status and acclimation to light gradient within canopies
A coupled photosynthesis-stomatal conductance model was parameterised and validated for grapevine (Vitis vinifera L.) in Mendoza (Argentine) and Montpellier (France).
Recovery of Cabernet-Sauvignon grapevines from long term water deficits
In the last decade, the impacts of long term drought and limited supply of water have led to severe reductions in the amount of irrigation water applied to winegrapes in Australia.
Characterization of aromatic precursors in grapes cv. Viognier B. (Vitis vinifera L.) and their relationship to vineyard trellis system and water status
Aromatic composition of grapes is essential to wine quality. Under Mediterranean conditions of southern France, a study was conducted to assess the impact of different vine water status and trellis systems on aromatic precursors on Viognier grapes.
New approach for grapevine irrigation scheduling using sap flow sensor: relationship with predawn leaf water potential
There are numerous methods proposed for vine irrigation control, but the reference standard certainly remains the leaf water potential in its three forms: predawn leaf water potential (ψPD), midday leaf water potential (ψL) and midday stem water potential (ψS).
Correlation of real time canopy temperature with soil moisture content and standard vine physiology measurements on Merlot and Cabernet-Sauvignon grapevines under two irrigation levels
A field trial was conducted in an experimental plot of Merlot and Cabernet Sauvignon grapevines during the 2010 season in the Central Valley of California.
Relationships among meteorological data, leaf gas exchange and anthocyanin content in ‘Nebbiolo’ berries grown in three different vineyards
This study was carried out in three vineyards (Alba, Serralunga and Novello, Cuneo Province, Italy) characterized by different soil and climate conditions. A meteorological station was located in each vineyard to measure temperature, relative humidity and rainfall.
Agronomic performance of Graciano, Petit Verdot and Tempranillo grapevine cultivars (Vitis vinifera L.) under two water regimes
For the last decades Spanish vineyard has experienced a deep transformation by allowing irrigation, changing the traditional bush into a possible full mechanized VSP and cultivar changing map was also took into account.
Biochemical approaches to study the effects of temperature on grape composition in cv. Sangiovese (Vitis vinifera L.)
High temperatures during ripening, especially after veraison, can affect berry composition in wine grapes.
The effect of lag phase water stress on berry shriveling and recovering after irrigation in cv. Cabernet-Sauvignon (Vitis vinifera L.)
This research was conducted in cv. Cabernet Sauvignon during the 2007 growing season in the ECOTRON of the campus of Montpellier SupAgro/France.
Climatic risk factors of Botrytis cinerea infection from climate change aspect
Some climatic indicators that have significant correlation with the rate of damage caused by Botrytis cinerea on Vitis vinifera varieties were defined.
Some new perspectives on the impact of vine balance on grape and wine flavor development
Experiments were conducted in several major growing regions of California to examine the impact of vine balance metrics (defined as the yield to pruing weight ratio) on the flavor development of Cabernet Sauvignon grapes
Management strategies to reduce bunch temperature in Australian vineyards
Severe heatwaves in southern Australia in recent years have resulted in high levels of leaf and bunch damage in many vineyards, with consequent losses in yield and quality.
The effects of cluster girdling on fruit growth, firmness, and composition
Clusters from Cabernet Sauvignon, Syrah, and Chardonnay vines were girdled by removing a ring of bark below and above the peduncle at 3 different times during the season
Effects of crop load and time of girdling on Sugrathirteen® table grape: first results
A specific research was carried out in 2010 at commercial vineyard of Sugrathirteen® variety located in a table grape growing area of Apulia region, Southern Italy.
Anthocyanin profile variability: changes in Sangiovese pigments acylation related to growing condition and viticultural management
The anthocyanin profile has been proposed as index of the varietal origin of wines. In Italy, it was recently discussed for Sangiovese grapes in the “Brunello di Montalcino” production.
The influence of various management practices on nitrogen reserves of the perennial structure in Shiraz grapevines in south-eastern Australia
The nitrogen (N) reserves stored in the perennial structure have an important role to buffer the grapevines demands under insufficient N uptake.
Anthocyanin concentration in Pinot noir berries and their extraction into wine as affected by rootstock
In 2003, a rootstock trial was established with Pinot noir grafted onto 5 rootstocks (125AA, SO4, Riparia Gloire, R110 and 101-14) in 4 field replicates at Geisenheim, Germany.
Effects of defoliation and cluster thinning on phenolic compounds and antioxidant activity of Sangiovese grapes
Cluster thinning down to one bunch per shoot applied at veraison and early leaf removal during anthesis stage were applied on Sangiovese vines
