Characterisation of the Auxin Signalling Pathway in Vitis vinifera L. cv. Shiraz
… receptor family members were identified in Vitis vinifera sp. The conserved domains were analysed in each group of proteins and their presence or absence related to possible function. Phylogenetic trees demonstrated the relationship of the Vvi genes with apple, Arabidopsis, poplar, and …

Effect of vineyard management of Cabernet Sauvignon (Vitis vinifera L.) grape glycosides
… crop levels from mature Cabernet Sauvignon (<i>Vitis vinifera</i> L.) vines grown in eastern Virginia were evaluated for their influence on grape glycosides, expressed as red-free glycosyl glucose (GG). Crop levels averaged 3.2, 5.1, and 6.4 kg/vine resulting in leaf area to fruit weight ratios …

Effects of Capture and Return on Chardonnay (Vitis vinifera L.) Fermentation Volatiles
Effectiveness of a capture and return system for the partial retention of fermentation volatiles, as a means of improving white wine quality, was evaluated. Twenty-three aroma-active volatiles including ethyl esters, acetate esters, fusel alcohols, and fatty acids, were quantified using head-space …

Relationships between berry sensory assessment and wine quality in Vitis vinifera L. Shiraz
Berry sensory assessment (BSA) is a technique that can help grapegrowers and winemakers make decisions about harvest date and grape product allocation. BSA as a structured technique has been used by grapegrowers, winemakers and researchers for the last thirteen years. However the number of studies …

Effect of Training Systems on Viognier (Vitis vinifera L.) Grape and Wine Glycosides and Volatile Compounds
Viognier (Vitis vinifera L.) grapes were grown in Northern Virginia for three seasons using three different training systems in a randomized complete block design consisting of Vertical Shoot Positioned (VSP), Smart Dyson (SD), and Geneva Double Curtain (GDC), and evaluated for the effects on grape …

Abiotic-Stress Application, Global Berry Proteome Profiling, and Cold-Stress Tolerance in Transformed Winegrape (Vitis vinifera L.).
Wine grape (Vitis vinifera L.) was domesticated more than 7,000 years ago and continues to provide one of the most important fruit crops worldwide. V. vinifera cultivars are moderately sensitive to salt and temperature stresses, whereas moderate water deficit stress results in minimal loss in berry …

Effect of canopy manipulation on rot incidence and rot metabolites of White Riesling (Vitis vinifera L.) grapes
… metabolites of Virginia grown White Riesling (<i>Vitis vinifera</i> L.) grapes. Due to the relatively high incidence of rot observed in these studies, an evaluation of the effects of rot on the sensory evaluation of juice and on selected aroma components was also undertaken. The effect of shoot …

The Relationship Between Mineral Nutrition and Late-Season Bunch Stem Necrosis of Cabernet Sauvignon (Vitis vinifera L.) Grapevines
Late-season Bunch Stem Necrosis (BSN) is observed as a necrosis of the cluster stem (rachis) that leads to shriveling of berries on the affected portion of the cluster. Field experiments were conducted over three years at two vineyards in northern Virginia to examine relationships between specific …
