The grape berries due to containing organic acids, sugars, aromatic compounds, phenolic compounds (including anthocyanins, flavanols, flavonols, stilbenes (resveratrol)), tannins, and oil in the pulp, skin, and seed have numerous health benefits for human health. In this study, we investigated genetic and phytochemical characteristics of four famous grapevine cultivars (Shiraz, Sirch, Panje Aro...

BACKGROUND The determination of micro-, macroelements and heavy metals in the soil-grapevine-wine system is extremely important for the wine industry, the grape and wine quality, and also for consumer health. The quantitative analysis of 10 elements: Na, Ca, Mg, Fe, Cu, Zn, Pb, Cd, Ni, Co were made in soil at different depths and also in grapevines (leaves and canes). For grape juice and wine t...

this research was conducted to study morphological and evaluation of genetic diversity of 15 grape cultivars in collections of agriculture and natural resources, research center of khorasan razavi based on completely randomized design with four replications. results showed extensive range of variations among cultivars and measured traits. in some key traits of tests for distinctness uniformity ...

background and objectives: grape has high nutritional value and it is an economically important horticultural plant in the world. iran has seventh producer grape rank in the world. today tissue culture is one of technique which can be used in grape propagation and breeding. material and method: in order to optimization of callus induction and micropropagation of grape in vitro condition, this i...

comparison and grouping of 32 grape cultivars and genotypes by using 61 traits including; 5 phenological and vegetative characters, 41 traits related to fruit and amount of resveratrol in 15 parts of plant was done according to grape descriptor and related methods. according to the results some traits such as spikelet weight, berry color, length of peduncle, length of berry tail, weight and len...

Polyphenolic profiles in the berry samples of 344 European grape (Vitis vinifera) cultivars were evaluated for two consecutive years. These cultivars represent a diverse collection of V. vinifera germplasm maintained at the USDA-Agricultural Research Service Vitis Clonal Repository in Davis of California, USA. A total of 36 polyphenolic compounds, including 16 anthocyanins, 6 flavonols, 6 flava...

Monoterpenols serve various biological functions and accumulate in grape (Vitis vinifera), where a major fraction occurs as nonvolatile glycosides. We have screened the grape genome for sequences with similarity to terpene URIDINE DIPHOSPHATE GLYCOSYLTRANSFERASES (UGTs) from Arabidopsis (Arabidopsis thaliana). A ripening-related expression pattern was shown for three candidates by spatial and t...

The grape yeast biota from several wine-producing areas, with distinct soil types and grapevine training systems, was assessed on five islands of Azores Archipelago, and differences in yeast communities composition associated with the geographic origin of the grapes were explored. Fifty-seven grape samples belonging to the Vitis vinifera grapevine cultivars Verdelho dos Açores (Verdelho), Arint...
