Foliar spraying of nitrogen and sulfur at veraison: A viticultural technique to improve aromatic composition of white and rosés wines
The aim of these studies is to evaluate the impact of nitrogen and sulfur foliar applications at the vineyard on the presence of varietal thiols in white and roses wines.
Finding the grape gaps: developing a profile of New South Wales wine grape growers – A scoping stakeholders study
The study identified key issues facing wine grape growing in New South Wales. Aimed at developing innovative methods to improve knowledge and change in the viticulture industry.
Evolution of canopy management: from history to scientific modeling
The diversity of the grapevine architectures is described and classified. Its explanation relies on the evolution of canopy management in the world which is presented from history to recent developments.
Evolution of canopy management in Italy: A key to reconcile remunerative yield, desired grape composition and cost reduction in the vineyard
A general trend of shifting from big-sized pergola or arched cane-trained vines to vertically-shoot positioned (VSP) hedgerows has been registered in Italy over the last two decades.
Evaluation of seven vermentino selections in a Mediterranean environment
Verrnentino (Vitis vinifera L.) is one of the most promising white wine grape varieties, traditionally cultivated in the west Mediterranean region and recently introduced into new viticultural areas.
Evaluation of modern rootstocks for concord grapevines in the Lake Erie production region
Concord ordinarily is cultivated on its own roots, but production can suffer due to damage from phylloxera and from water stress.
Evaluation of in-row cover cropping as a vineyard management tool
One large-plot experiment and a small plot experiment was established in 2005 in a first leaf vineyard to evaluate the impact of in-row barley cover cropping on soil and water erosion, vine growth and productivity, weed control, and soil characteristics.
Evaluating climate change impacts on viticulture using the MCC system
Climate change may modify the viticultural and enological potentials of the productive regions around the world. Methodologies to evaluate the impact of climate change over grape-growing regions of the world are necessary.
Estimation of sensible heat flux and latent heat flux for complex slopes vineyards using surface renewal analysis
We estimated sensible heat flux and latent heat flux (ET) above a flat vineyard, a sloped northeast aspect vineyard (NE) and a sloped southwest aspect vineyard (SW) in California’s Napa Valley using surface renewal analysis.
Enological research about the wines produced in the “cordon spur of Cargnello”, in the “minimum pruning of Clingeleffer”, in the “vertical tridimensional minimal pruning of Cargnello” with DMR (“double reasoned maturation” of Cargnello) and in the “zero minimum input system of Cargnello”
In a precedent works it has been shown the greater viticultural, oenological, social- economic existential, ethical and “MetaEthical” interest for”Cordon Spur of Cargnello or Conegliano”
Effects of the plantation density on grape and wine quality in the particular case of high slope situation in Beaujolais-Villages vineyard
Economical stakes that threaten the exploitation of vines with strong cultural constraints, problems of erosion for vines in high slope and in light soil, environment subjects
Effects of temperature and ABA on anthocyanin concentration and total polyphenols in grape berries in vitro (Vitis vinifera L. cv. Cabernet-Sauvignon)
The synthesis of anthocyanins in grape berries depends on different environmental factors. The temperature is the main climatic factor.
Effects of pre-bloom defoliation (hand vs mechanical) on gas-exchange, yield components and must composition in Sangiovese (V. vinifera L.)
Recent trials on Sangiovese vines have shown that hand defoliation of shoot basal leaves at pre-bloom is effective in reducing fruit-set and yield, leading to better grape quality composition.
Effects of partial defoliation at different phenological stages on yield and fruit composition of cv. Istrian Malvasia
Partial defoliation is a common grapevine canopy manipulation practice in Istria (Croatia).
Effects of mesoclimate and vintage on grape composition in a warm summer region
The main goal of this investigation was to determine how mesoclimate and vintage affect the maturity of Grenache and Carignan bunches cultivated in the Terra Alta Appellation (Tarragona, Spain).
Effects of irrigation and stage of berry development on leaf gas exchange inmerlot and Cabernet-Sauvignon grown on a coarse soil
The relative influences of irrigation, crop load and stage of berry development on stomatal conductance (gs) photosynthesis (A) and transpiration (T) were examined in drip irrigated Merlot and Cabernet Sauvignon vines grown on a coarse textured soil in a low-humidity climate.
Effect of variability in ripeness on wine composition of Pinot noir grapevines in Marlborough, New Zealand
Although uniformity or synchrony of development is perceived as advantageous, there is no experimental evidence linking variability in ripeness with wine composition and sensory properties.
Effect of shoot number on vine balance and berry composition of Tempranillo grapevines
In order to study the effects of shoot density on vine balance and its influence on yield and berry composition, an experimental trial was carried out during 2007 and 2008 using Tempranillo grapevines (Vitis vinifera L.) grafted onto 110R and vertical shoot positioned.
Effect of row orientation on soil water content and vine water status on a Cabernet franc vineyard in Madrid, Spain
The aim of this study was to evaluate the effects of row orientation on vine and soil water status in an irrigated vineyard.
Effect of Forchlorfenuron on fruit set in ‘Merlot’ winegrapes
The effect of the synthetic cytokinin CPPU on fruit set was evaluated in the wine grape cultivar ‘Merlot’ which tends to have reduced fruit set if cool weather persists during bloom.
