reports have shown the antioxidant, hypotensive, hypolipidemic and vasodilatory effects of grape (vitis vinifera l.) seed extract. we have recently shown the relaxatory effect of grape leaf extract on rat uterus and reduction of frog heart rate and contractility. the aim of the present study was to investigate the relaxant effect of vitis vinifera leaf hydroalcoholic extract (vlhe) on rat thora...

Pollen morphology is an important parameter. In this study, the pollen of selected in 10 grape cultivars were examined by SEM (scanning electron microscopy). The surface features observed, such as length, width, and P/E ratio pollen. differed some microstructural characteristic. width exhibited significant according to varieties (10.12-22.44 µm). Smilarly, statistical difference occurred among ...

222 cultivated (Vitis vinifera) and 22 wild (V. vinifera ssp. sylvestris) grape accessions were analysed for genetic diversity and differentiation at eight microsatellite loci. A total of 94 alleles were detected, with extensive polymorphism among the accessions. Multivariate relationships among accessions revealed 16 genetic groups structured into three clusters, supporting the classical eco-g...
