Abstract (sommario):

Interest in grape juice has risen as the public becomes more aware of natural foods and the specific evidence of healthful benefits of grapes. Among major preharvest conditions that influence quality of grape juice are climate, soil, cultivar, vineyard management, and maturity. Each of these factors exerts its own influence, but complex interactions among these factors must be recognized. For mechanically harvested juice grapes, cultivar takes on special importance to quality and yield as do the production system, harvest machines, postharvest handling systems, and processing method.

The elite grape varieties developed by conventional breeding techniques have less resistance to fungal and bacterial diseases, drought, quality and yield per plant. Breeding programs of grapes are difficult due to lack of true bred from seed and few traits of importance. Though most grapes constitute large number of genes, they have less effect in tolerating biotic and abiotic stresses. Genetic improvement of grapevine (Vitis vinif

At the same density, the shade-net color significantly affected cooling and shading efficiencies, with gray nets showing the best light transmission and cooling effect.

Previous releases were ‘Venus’ in 1977 (Moore and Brown, 1977), ‘Reliance’ in 1983 (Moore, 1983), and ‘Mars’ in 1984 (Moore, 1985). These cultivars are the foundation of an emerging commercial table-grape industry in the region. ‘Saturn’, a high-quality, red seedless grape with good storage and shelf-life characteristics, is expected to contribute to further expansion of the commercial industry.

Abstract (sommario):

Wine quality is determined by the development of grape maturation, which is highly dependent on climate variations. Extreme weather events are becoming more common, which will affect the productivity and quality of grapes and wine. Grape development depends on many factors, including weather, and extreme events will influence berry size, skin thickness and the development of some key compounds, such as phenolics. In this work, the ripening evolution and phenolic content of Vitis vinifera extracts from a vineyard in Alentejo (Portugal) were evaluated in two distinct climatic years. During this

Abstract (sommario):

Viticulture is of great economic importance in the southern part of Bosnia and Herzegovina, thanks to favorable climatic conditions and a long-standing tradition of growing vines. The assortment is dominated by international varieties, as well as some autochthonous and domesticated varieties. The subject of the research is the analysis of the quality of Cabernet Sauvignon, Merlot, Vranac, and Blatina varieties at two localities in Herzegovina during the period 2020–2021. The paper examined the most important economic and technological characteristics, grape quality, and berry phenolic profile.

Abstract A grape breeding program was begun in 1964 by the Arkansas Agricultural Experiment Station with the primary objective of developing high quality table grapes adapted to the soils and climate of the Ozarks region. Two cultivars previously have been released from this program: ‘Venus’ in 1977, a blue seedless grape (2); and ‘Reliance’ in 1982, a red seedless (1). These cultivars show promise of being the foundation of a commercial table grape industry in the region. ‘Mars’, a blue seedless table grape with high levels of disease resistance, is being released to fulfill the needs for hom

Abstract (sommario):

This study aimed to establish if there is any evidence that soil mineralogical and/or chemical composition influence the composition and quality of wine grapes. In the initial phase of the study, soils and grapes were sampled in two riesling vineyards in South Australia. Soils were analysed for a wide range of total major and trace elements; soil cation extracts and grape juices were analysed for 27 trace elements by ICP-MS and ICP-AES. The results show that grape juice properties such as Baumé and titratable acidity (TA) are clearly correlated with several plant-available trace elements in th

Abstract (sommario):

Spine grape (Vitis davidii Foëx), an important wild grape species in South China, has gained attention because of its health-promoting effects and use in the wine industry. Fruit quality plays an important role in determining the quality of wine; however, a suitable evaluation system to monitor its fruit quality has not been established. The fruit quality characteristics (phenolics and aromas) of 15 spine grapes grown in China were evaluated using a combination of principal component and cluster analyses. The total sugar, organic acid, and phenolic content ranged from 81.80 to 154.89 mg·g−1, 8

Abstract (sommario):

Brassinosteroid (BR) is an important endogenous phytohormone that plays a significant role in fruit quality regulation. The regulation of BR biosynthesis and its physiological effects have been well-studied in various fruits. External quality (fruit longitudinal and transverse diameters, firmness, single berry weight, color) and internal quality (sugars, aroma, anthocyanin, stress-related metabolites) are important parameters that are modified during grape berry development and ripening. Grapevines are grown all over the world as a cash crop and utilized for fresh consumption, wine manufacture

Abstract (sommario):

This study examines vertical coordination in the wine industry emerging in Illinois. We find that quality matters as temporal issues related to grape perishability increase the probability of written contracts being used to procure grapes. Holdup concerns related to sourcing adequate quality grapes and at-risk investments in grape storage and winemaking equipment lead to vertical integration. In general, larger wineries must obtain some grapes from outside vineyards and sell wine predominantly through tasting rooms and distributors. Smaller wineries rely more on direct sales to retailers, fest

Mulching has been used widely to improve the production capacity of the soil, yield and the quality of wine grapes (Vitis vinifera L. cv. Cabernet Sauvignon). However, the ecological mechanisms underlying the mulching materials were not well understood. This study aimed to evaluate the effects of different mulching materials on soil chemical properties, bacterial community and wine grape quality. Experiments were performed at a grape-yard on the six-year-old wine grape ‘Vitis vinifera L. cv. Cabernet sauvignon.
