Effect of factors related to the training system in vineyards on a remotely–sensed vegetative index
Viticultural applications of remotely sensed images are generally interpreted at an individual field level.
Application of an automatic sampler to intact winegrape analysis by FT-NIR technology
Spectroscopic techniques such as near infrared are used in the food industry to monitor and assess the composition and quality of products.
Berry sensory assessment (BSA)–should frozen wine grape berries be used in sensory evaluations? Is BSA important for winemakers and grapegrowers?
Shiraz grapes from vines grafted to three different rootstocks and on own roots were collected at optimum harvest time to evaluate the effect of freezing on grape sensory characteristics.
Influence of irrigation managements as partial rootzone drying, deficit irrigation and sustained stress irrigation, on vegetative and productive parameters of Vitis vinifera L. cv Cannonau
The paper shows the results of a four years experiment on a native sardinian grapevine (Cannonau), irrigated according to different strategies:
Wild grapevine and cultivated grapevine: where is the frontier?
The History of Vitis vinifera silvestris and of Vitis vinifera sativa is summarized.
Wine, alcohol and health: what are the questions we must ask?
An important study called ‘‘Alcohol and risk of cancers’’ was recently published for health professionals.
Knowledge and perception of the Prosecco wine among foreign people
Giving that Prosecco wine consumption is increasingly growing also among non-Italian wine drinkers, we present a study on foreigners’ current level of knowledge of this wine.
Climatology, ecophysiology, vine performance – A set of strange connections
The current study describes a detailed analysis of 7 grape growing regions well-known for the cultivation of Riesling (Rheingau, Germany; Okanagan Valley, Canada; Yakima Valley, USA; Vienna, Austria; Blenheim, New Zealand; Adelaide Hills, Australia; and Colmar, France)
Leaf removal, vine physiology and wine quality in cv. Negroamaro (Vitis vinifera L.)
Negroamaro has a very dense canopy. Farmers improve the bunch microclimate by removing leaves and laterals in that zone.
Effect of basal leaf removal and nitrogen nutrition on grape quality of Sauvignon blanc
Both nitrogen supply and leaf removal can affect grape and wine quality. Nitrogen fertilization trials have been made for long time in grapevine as in other crops, being N the most important element for plant development.
Analysis of berry growth and maturation as related to cropping levels and seasonal variation
Growing grapes in Michigan, or in any cool-cold climate region, requires several tools to manage both yield and ripening potential.
Ecophysiological and agronomic response of two ‘Nebbiolo’ clones to different leafroll virus infection
The healthy and the infected descendants of two clones of Vitis vinifera L. cv. Nebbiolo were compared in a vineyard of Piedmont (north-west Italy).
Assessing whole canopy gas exchange through a functional-structural plant model for grapevine (cv. Syrah)
A functional structural plant model was developed in order to asses whole canopy gas exchange. The model is based on a detailed description of the canopy structure (leaf number, size, and orientation), a quantification of light interception within the canopy, and a leaf gas exchange model.
Shoot thinning effects on seasonal whole-canopy photosynthesis and vine performance in Vitis vinifera L. cv Barbera
While shoot thinning is one of the most widely applied practices in the vineyard as a tool to regulate canopy density and/or crop level, its physiological bases are still fairly obscure and have been poorly investigated.
Spatialisation of vine water and nitrogen status at the estate level or at the block level
Vine water and nitrogen status greatly impact vine behaviour and grape composition at ripeness. Moderate limitations in water and/or nitrogen uptake increase grape quality potential in red wine production.
Effects of late-season source limitations induced by trimming and anti-transpirants canopy spray on grape composition during ripening in Vitis vinifera cv. Sangiovese
The global warming and the general improvement of vineyard management techniques over the last fifty years appear to have upgraded the quality of wine worldwide.
Variation in starch and nitrogen reserve storage by grapevines and measurement by ATR-FT-IR spectroscopy
Knowledge of the over-wintering carbohydrate and nitrogen reserve status of grapevines may provide growers with an advanced indication of yield and canopy growth potential in the following season.
Carbohydrate dynamics of Chardonnay grapevines affected by irrigation reduction and recovering regimes
Changes in global climate and decreased water availability over the past 10 years in Australia have prompted research into the short and long term effects of environmental stresses on grapevines and their resilience to those stresses.
Grapevine cold hardiness: A model and implications for climate change
Cold injury remains an environmental challenge in many fruit-producing regions. Cold hardiness of grapevines (Vitis spp.) varies dynamically throughout winter, mainly in response to changes in temperature.
Effect of climatic conditions and cultivar on total nitrogen and individual free amino acid content of grapes in Navarra and La Rioja (Spain)
Free amino acids and ammonia stand for the majority of nitrogen
(N) containing compounds in wine grapes. Yeast available nitrogen (YAN) is routinely measured in wineries, since low nitrogen levels may deter yeast activity, resulting in stuck fermentations and excessive thiol formation.
