Antithrombotic activity of Vitis labrusca extract on rat platelet aggregation
Blood Coagulation & Fibrinolysis, 2016Vitis labrusca is a grapevine that has antioxidant, neuroprotective, hepatoprotective, and anticarcinogenic activity. However, the antithrombotic effect of Vitis labrusca leaves on platelets is yet to be ascertained. We investigated the inhibitory effect of V. labrusca leaf extract (VLE) on platelet aggregation in vitro and ex vivo. The thromboxane B2 (

Rooting and acclimatization of grapevine hybridsVitis labrusca×Vitis rotundifolia
Acta Horticulturae, 2018Rhizogenesis is an important step in micropropagation and root quality is essential for plant survival during acclimatization. Vitis rotundifolia hybrids show low rooting rate and auxin application is important for cutting propagation. This study was aimed at evaluating different concentrations of naphthalene acetic acid (NAA), 0.0, 0.2, 0.4 and 0.8 µM,

Grapevine rust Phakopsora euvitis is an important disease in tropical and subtropical grapevine-producing areas, and both American (Vitis labrusca) and European (Vitis vinifera) grapevine species are sensitive to rust. Grapevine rust can cause early plant defoliation, reducing photosynthesis and photoassimilate supply and storage.

Macrophage stimulating polysaccharide purified from peels of grape (Vitis labrusca) [PDF]
Food Science and Biotechnology, 2010 To characterize the macrophage stimulating polysaccharide in grape (Vitis labrusca) peels, the active crude polysaccharide (VL-3) has been fractionated from the hot-water extract of grape peels. A macrophage stimulating polysaccharide-rich fraction (VL-3IIb-1-1) was purified from VL-3 by 3 successive column chromatographies on DEAE-Sepharose CL-6B ...

Virtual lesions and photosynthetic damage caused by Plasmopara viticola in Vitis labrusca
European Journal of Plant Pathology, 2019Downy mildew caused by Plasmopara viticola is the most destructive disease of grapevines. However, the mechanisms of damage caused by P. viticola to photosynthesis in Vitis labrusca remain unknown. Our aim was to quantify the effects of downy mildew on leaf gas exchange in V.

The aim of this study was to characterize grape pomace (GP) from winemaking byproducts of different grape samples (Cabernet Sauvignon-CS; Merlot-ME; Mix composed of 65% Bordeaux, 25% Isabel and 10% BRS Violet-MI and Terci-TE) with a view to exploiting its potential as a source of bioactive compounds and an alternative to the reuse of waste.

Diversity of Aspergillus section Nigri on the surface of Vitis labrusca and its hybrid grapes
International Journal of Food Microbiology, 2018This study investigated the presence of Aspergillus species belonging to Aspergillus section Nigri on Vitis labrusca and its hybrid grapes grown in Brazil. The ability of the fungi isolates to produce ochratoxin A (OTA) and fumonisin B2 (FB2) as well as the presence of these mycotoxins in the grapes were also studied.
