Climatic conditions and rootstock influence on the phenolic composition of tropical Brazilian wines

Abstract

Using spectrophotometric and chromatographic methods were evaluated the influence of climatic conditions and rootstock on the phenolic composition of young varietal wines on tropical wines-area, produced from cvs. Cabernet Sauvignon, Marselan, Syrah and Tempranillo, during 2009-2010.  The results are analysed with multivariate analysis. The 2010 harvest exhibited superior results for the phenolic composition of the wines, although the 2009 harvest provided the best climatic conditions. This difference showed the effects of the amount of rainfall on the phenolic composition. Furthermore, an interrelationship was found between the rootstock and the cultivars, especially in the 2009 harvest.

Risk of late frost events in viticulture – temperature trends, phenological observations and spatial analysis based on digital terrain models in Franconia/Germany

In the course of global warming a general decrease of frost days per year and in spring can be stated. However, in viticulture this matter of fact doesn´t lead to a reduction of the risk of damages to grapevines by late spring frost events.

Estimating leaf area and leaf area index in VSP trained grapevines under different management systems (Vitis vinifera L. cv. Riesling)

The aim of this study was to validate and implement different non-destructive methods of leaf area and leaf area index (LAI) determination in VSP trained grapevines (Vitis vinifera L. cv. Riesling) in a field trial comparing different management systems (i.e. integrated (GAP) and two different organic (European Union Regulation 834/07) management systems).

Classification for timing of flowering and veraison of a wide range of Vitis vinifera cultivars with the “GFV” model

In viticulture, the timing of phenology is critical to optimize grape quality potential particularly so in cool climates. Flowering and veraison are key phenological stages for grapevines.
