Genetic Engineering of 2,4-D Resistance in Wine Grapes
… plantings around areas where it is used. Since grapes have no known genetic resistance to this herbicide, breeding to incorporate resistance in commercial cultivars cannot be done. Thus genetic engineering has to be employed to produce adaptable grape cultivars. The overall objective of this …

Japanese beetle Popillia japonica Newman: foliar feeding on wine grapes in Virginia
The natural infestation level for 1985 of the Japanese beetle, Popillia japonica Newman, in the Shenandoah Valley of Virginia failed to reduce berry quality, yield or shoot growth in a commercial vineyard. Intensive postveraison foliage feeding by Japanese beetle resulted 1n fruit with lower …

Investigation of bacteria associated with Australian wine grapes using cultural and molecular methods
… of bacterial species associated with wine grapes cultivated in Australian vineyards during 2001-2004. Grapes, sampled throughout cultivation, were analysed for bacterial species using a combination of cultural and molecular methods. Red (Shiraz, Cabernet Sauvignon, Merlot) and white …

Effects of Horticultural Oils on Photosynthesis, Fruit Maturity, and Yield of Wine Grapes
… at 5550 L/ha and 4680 L/ha was applied to 23 wine grape cultivars. Eleven cultivars had significant foliar injury but injury was not related to reductions in fruit maturity. Experiments conducted in 1999 determined if reduced spray volumes or applications to only the fruit zone minimize …

Fungicide Resistance of Botrytis Cinerea from Virginia Wine grapes, Strawberry, and Ornamentals Crops
… of the species complex that causes bunch rot of grapes and gray mold disease on other hosts including fruits and ornamental crops. It has developed resistance to many fungicides, and isolates from eastern US strawberry fields have regularly been identified with resistance to several modes of …

Breeding strategies for wine grapes: From genetic analysis of agronomic traits to wine sensory evaluation
… of the genetic basis of agronomic traits in wine grape, the assessment of the influence of berry size in the oenological composition of segregating progenies and clones; and the sensory evaluation of wines derived from Graciano × Tempranillo selections. Two segregating progenies derived from …

Isolation And Characterization Of Natural Alpha-Glucosidase Inhibitors From Antioxidant Rich Red Wine Grapes (vitis Vinifera)
… Norton, Petit Verdot, Syrah and Tinta Cao red wine grape pomace extracts were assessed for their rat intestinal alpha-glucosidase inhibiting activity and antioxidant properties via biochemical assays and UV detection. Then, the grape pomace variety shown to potently inhibit the enzyme was …

Quantifying bird damage to wine grapes in the Western Cape of South Africa : a questionnaire-based approach
Bird-wine grape damage is a globally acknowledged problem that has been the subject of considerable research in many wine growing regions. However, despite the Western Cape of South Africa being a major wine grape growing region, very little research has quantified bird damage in this region and …

Study of Ochratoxin A biosynthesis by Aspergillus ochraceus and incidence of ochratoxigenic fungi on Wine Grapes from Southern Illinois
… a survey to investigate the mycoflora of grapes grown in Southern Illinois and assess the risk of presence of OTA- producing fungi in these grapes. The study revealed a predominance of <Aspergilli> in the isolated fungal population compared to <Penicillia> and the presence of three …

Impacts of climate change on wine grape farming in the Western Cape: Implications for adaptation
… in the Western Cape's most highly productive wine grape growing regions by the 2040s. This could pose serious challenges to the yield and quality of wine grapes produced in the region, as it negatively affects the Mediterranean-like conditions that are desirable for wine grape production. …

Quantitative Trait Loci (Qtl) Analysis Of Sulfur Sensitivity In Vitis Aestivalis-Derived 'Norton'
<p>The grape and wine industry relies heavily on sulfur and sulfur containing compounds to control the fungal disease powdery mildew (PM). Sulfur dioxide induces large-scale transcriptomic modification in the Eurasian grape species Vitis vinifera with little to no phytotoxicity. However, genetic …

INDUSTRY 4.0 IN THE AGRI-FOOD SECTOR: INNOVATIVE SENSORS AND SMART LOGISTICS TO SUPPORT THE SUSTAINABILITY OF THE SUPPLY CHAIN
… was developed and tested on olives, tomatoes and wine grapes and it has been designed specifically for use on small-sized matrices. The optical device was used to evaluate table tomatoes' quality features and then to quantify qualitative parameters of Chardonnay grapes directly in the field. …

Exploring Chemically Mediated Interactions Between Spotted Lanternfly, Lycorma delicatula, and Its Host Plants in the Mid-Atlantic Region of the United States
… honeydew threaten specialty crops, especially wine grapes. Management often relies on insecticides and removal of tree-of-heaven (Ailanthus altissima), a preferred host from which L. delicatula sequesters quassinoids for chemical defense. Yet how volatile semiochemicals and sequestration …

Drosophila suzukii (Matsumura) (Diptera: Drosphilidae): Risk Assessment For An Invasive Vinegar Fly In Virginia Vineyards
… commercially available baits that contained red wine caught the most D. suzukii, but none were exclusively attractive to D. suzukii. Wine grape susceptibility was assessed in laboratory choice and no-choice ovipositional bioassays. Ovipositional susceptibility was determined by measuring the …

Good Grapes - Good Wine.
<p>Good grapes are required to make good wine. Quality wines start in quality vineyards. Vineyard design, installation, and operation, including site location, trellis options, vine selection, and canopy management, along with when to harvest are discussed. While winemaking is the final phase in …
