Niagara Peninsula, where much of the wine industry in Canada is located, has experienced an increase in the frequency of dry and hot weather during the summers throughout the last decade.

A two-year study on the effects of early defoliation on yield components and wine composition was conducted on cv. Tempranillo (Vitis vinifera L.).

Grapevine buds are compressed shoots that form at the axils of leaves as they separate from the apical meristem of the shoot (N shoot).

Grapevines are colonized by arbuscular mycorrhizal fungi (AMF) and are completely dependent on their mycorrhizal partners to acquire enough phosphorus in some soils.

Piedmont is the district where ‘Nebbiolo’ is mainly culti- vated (53250 hectares) and where it gives origin, depending on growing areas, to different VQPRD wines

Wines are produced traditionally in temperate climate zones, with one harvest per year. Tropical wines are a new concept of vitiviniculture that is being developped principally in Brazil.

This study tested whether the requirement of grapevines to ripen their fruit may interfere with cold acclimation in autumn.

Within the crop level experiment described by Lakso et al. (in this volume), the goal of this research was to determine the effects of extended periods of varying crop level on vine growth

The goal of this research was to determine the effects of extended periods of varying crop level on vine growth, root production and dry matter distribution in mature ‘Concord’ grapevines.

The production costs of the Prosecco and Amarone wines was investigated and studied in the most significant winegrape areas in the Veneto Region (in Treviso for Prosecco and in Verona for Amarone).

The responses of Vitis vinifera L. cv. Cabernet Sauvignon to exogenous ABA supply and water stress treatments were assessed by in field culture in Mendoza province, Argentina.

In the wine-producing regions of southern France, characterized by a relatively warm and increasingly dry climate, a progressive increase in pH and K+ content and a reduction of the acidity of musts and wines have been observed over the last two decades.

In 2008 a research was started, focusing the attention on the use of proximal sensing tools in order to understanding and monitoring existing variability in vineyards and, basing on it, evaluating agronomical practices and consequent qualitative and quantitative productive responses.

Variability within cv. ‘Plavac mali’ in the preselection of clones is presented here. After the selection and evaluation of divergent vines at the original location (2-3 years), the majority of them were propagated in a homogeneous ex situ plantation (6 vines per mother vine).

Lately, grape growers and wine makers have been concerned about SOUR (Suppression of Uniform Ripening), berries, a ripening disorder also known as Berry Shrivel in viticulture parlance.

Different Vitis vinifera international cultivars as Merlot, Cabernet-Sauvignon, Pinot noir, Tempranillo, Sauvignon blanc, Riesling, Chardonay, Pinot gris, Pinot blanc and Gewurztraminer are grown in Estación de Viticultura y Enologia de Galicia

A decline in plant transpiration has been widely observed to occur within a fairly stable range of threshold values of FTSW (Fraction of Transpirable Soil Water), usually 0.3-0.4.

This study was designed to assess the effects of the conversion of oak woodlands to vineyards on the soil profile distribution of C and SOC characteristics.

The effect of canopy side sun exposure on the development of bunches at different ripeness levels was determined.
