providing healthy food and protecting sources from pollution has been one of the concerns of human societies and decision – making centers so that protecting food from pollution, detecting sources of pollution and measuring them become important. because of nutritive and political significance of grape in this area, extensive use of leaf and fruit of this plant, developing urban areas around gr...

The genus Vitis is represented by several coexisting species in Europe. Our study focuses on naturalised rootstocks that originate in viticulture. The consequences of their presence to the landscape and to native European species (Vitis vinifera ssp. silvestris) are evaluated. This study compares ecological traits (seven qualitative and quantitative descriptors) and the genetic diversity (10 SS...

Grape is one of the most important fruit crops worldwide. The suitable geographical locations and productivity of grapes are largely limited by temperature. Vitis amurensis is a wild grapevine species with remarkable cold-tolerance, exceeding that of Vitis vinifera, the dominant cultivated species of grapevine. However, the molecular mechanisms that contribute to the enhanced freezing tolerance...

Grapevine phylloxera, Daktulosphaira vitifoliae (Fitch) (Hemiptera: Phylloxeridae) is a worldwide pest of Vitis species. It has forms that feed on leaves and roots. Root forms predominate on Vitis vinifera (L.) cultivars, while leaf forms predominate on Vitis species from its native American range. Recently, high densities of D. vitifoliae infestations in leaves of V. vinifera in Brazil, Peru, ...

Hybridization of introduced domesticates and closely related natives is well documented in annual crops. The widespread introduction of the domesticated grapevine, Vitis vinifera, into California where it overlaps with two native congenerics, with which it is interfertile, provides opportunity to investigate hybridization between woody perennials. Although geographically widespread, the introdu...

We report on the Tydeidae and Triophtydeidae associated with grapevine (Vitis labrusca L. and Vitis vinifera L.) in Rio Grande do Sul State, Brazil, and describe a new species of Prelorryia, Prelorryia labrusca sp. nov., and two new species of Tydeus, Tydeus manoi sp. nov. and Tydeus riopardensis sp. nov. Brachytydeus formosa (Cooreman), B. podocarpa (Baker), Neolorryia pandana (Baker), Tydeus ...

We gathered genomic data from grapes (Vitis vinifera ssp. vinifera), a clonally propagated perennial crop, to address three ongoing mysteries about plant domestication. The first is the duration of domestication; archaeological evidence suggests that domestication occurs over millennia, but genetic evidence indicates that it can occur rapidly. We estimated that our wild and cultivated grape sam...

Resveratrol is positively correlated with grapevine disease resistance and its consumption is also highly beneficial to human health. HPLC analyses showed that resveratrol content was significantly higher in most wild Chinese grapevines than in most European Vitis vinifera grapevine cvs. Fruit of the wild Chinese genotype Vitis quinquangularis Danfeng-2 contains much higher levels of resveratro...

The Aqueous Extract of Vitis vinifera leaves was investigated for its effect on some immunoglobulin in induced hyperthroidism rabbits . The equeous extract of leaves at does level of 100 mg ml showed significant increase ( p<0,05) on level of IgG and significant decrease ( p < 0.05) on level of IgA , IgM to normal level .
