objective: scientificstudies have shown that vitis vinifera (v. vinifera) contains flavonoids and stillbenoids. flavonoids are well known to possess anxiolytic activities. in view of the idea that flavonoids present in v. vinifera could be useful in anxiety, we evaluated anxiolytic-like activity of v. vinifera juice (vvj). materials and methods: light/dark box and the open field test were used ...

Lignin was used as a natural adhesive to manufacture Vitis vinifera fiberboards. The fiberboards were produced at laboratory scale by adding powdered lignin to material that had previously been steamexploded under optimized pretreatment and pressing conditions. The kraft lignin used was washed several times with an acidic solution to eliminate any contaminants and low molecular weight compounds...

To investigate the hepatoprotective potential of ethanolinc grape seed extract on acetaminophen (APAP) induced liver toxicity in wistar rats. Silymarin was used as reference hepatoprotective agent. Liver injury was induced by APAP (2 gm/kg body weight, bw) on the 1st day of experiment. Vitis vinifera (V. vinifera)L seed extract (200 and 400 mg/kg bw) and silymarin (100 mg/ kg bw) was administer...

The Amur grape (Vitis amurensis Rupr.) thrives naturally in cool climates of Northeast Asia. Resistance against the introduced pathogen Plasmopara viticola is common among wild ecotypes that were propagated from Manchuria into Chinese vineyards or collected by Soviet botanists in Siberia, and used for the introgression of resistance into wine grapes (Vitis vinifera L.). A QTL analysis revealed ...

Next-generation sequencing technologies promise to dramatically accelerate the use of genetic information for crop improvement by facilitating the genetic mapping of agriculturally important phenotypes. The first step in optimizing the design of genetic mapping studies involves large-scale polymorphism discovery and a subsequent genome-wide assessment of the population structure and pattern of ...

One of the most commonly encountered plant-parasitic nematodes in eastern Washington Vitis vinifera vineyards is Meloidogyne hapla; however, limited research exists on the impact of this nematode on V. vinifera. The objectives of this research were to determine the impact of M. hapla on Chardonnay and Cabernet Sauvignon vine establishment and to determine the host status of V. vinifera varietie...

The aerial parts of Vitis vinifera Linn. (Common grape, Hindi ⎯ Angur) have been widely used in Ayurveda to treat a variety of common and stress related disorders. The seed extract of grapes was evaluated by Sreemantula and others for antistress activity in normal and stress induced rats. Furthermore, the extract was studied for nootropic activity in rats and in vitro antioxidant potential to c...

The present work aims to study the interactive effect of drought stress and high vapour pressure deficit (VPD) on leaf gas exchange, and especially on mesophyll conductance to CO(2) (g(m)), in two woody species of great agronomical importance in the Mediterranean basin: Vitis vinifera L. cv. Tempranillo and Olea europaea L. cv. Manzanilla. Plants were grown in specially designed outdoor chamber...

In herbivorous insects with more than 1 host plant, attraction to host odor could conceptually be mediated by common compounds, by specific compounds released by each plant or by combinations of common and specific compounds. We have compared the attraction of female grapevine moth, Lobesia botrana, with specific and common (shared) odors from 2 different plants: a wild host (Daphne gnidium) an...
