Grafting, which involves combining two different varieties or species to form a plant with new characteristics, is a technique known from ancient times in tree fruit and grape production. It was, however, used in viticulture only for certain special cases: to change variety, increase vigor, or increase limestone tolerance. The principal reason for the increased use of grafting in viticulture wa...

Aim of study: The main aim this study was to evaluate the effect overliming with dolomitic lime on topsoil and grapevine macro-nutritional levels (both petiole grape tissues), as well berry weight must quality properties in grapevines growing an acid soil.Area carried out viticultural region El Bierzo (Spain), one wine protected designation origin northwest Spain.Material methods: effects were ...

Polysaccharides in wine play important roles the stabilization and sensory properties of wines. Elicitor application constitutes an interesting field research since it is indirectly involved accumulation grape cell walls molecules like callose, lignin, phenolic compounds glycoproteins. Currently, biomimetic calcium phosphate (ACP) nanoparticles are successfully used viticulture for controlled d...

Yields on 'Concord' grape (Vitis labrusca L.) increased as pruning severity was decreased until the 6th and last year of this study, at which time the yields tended to equalize between the 30 + 10, 50 + 10, and 70 + 10 pruning treatments. By the last year, vines pruned to the 70 + 10 level produced fruit of unacceptable quality. When the 3-node spurs were shoot-positioned, their productivity wa...
