The effect of supplementation of Riesling (Vitis vinifera L.) must with ammonium sulphate (AS) on tryptophan (Trp) and indole-3-acetic acid (IAA) metabolism during alcoholic fermentation with four commercial yeast strains (Uvaferm CEG, Lalvin Cross Evolution, Anchor VIN 13 and Anchor exotic SPH) were examined. AS addition reduced Trp uptake by yeasts from 1% to 15%. Wines produced by Anchor VIN...
BACKGROUND Fruits of Vitis vinifera L., commonly known as grapes, are largely consumed worldwide because of their high nutritional and medicinal benefits. CONTEXT AND PURPOSE The present study investigated effects of V. vinifera fruits in ovalbumin-induced animal model of bronchial asthma. METHODS Male wistar rats (except group 1) were sensitized with allergen (ovalbumin, 40 mg/rat + alumin...
محاسبه کارایی فنی یکی از روش هایی است که می تواند به محققین کمک کند تا فاصله تولیدکنندگان از بهترین تولید ممکن را اندازه گیری و علل این فاصله را شناسایی و بررسی نمایند. در محاسبه کارایی فنی فقط نهاده های فیزیکی مؤثر بر تولید مورد مطالعه قرار می گیرند و ارزش ریالی نهاده ها در نظر گرفته نمی شوند. بهترین گام، تعیین و محاسبه تابع تولید است که با این کار نهاده های مؤثر شناسایی و ضریب تأثیر آن ها در ...
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...
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...
