Comparison of six Gamay noir clones in a high-altitude environment

Abstract

The agronomical and oenological performance of six clones of Gamay noir (V. vinifera L.) were evaluated for two years in a high altitude en­vironment (about 750 m asl) in Aosta Valley (North-Western Italy). Clone IAR4, selected by the Institut Agricole Régional in very similar en­vironmental conditions, was compared to five INRA clonal selections for phenological timing, yield components, vegetative growth/fruiting balance, juice and wine composition. A significant variability for most of the considered traits was observed. Clone IAR4 seems to be particu­larly well suited to the considered environment due to its regular yield, high sugar content and, above all, consistently well-balanced juice and wine acidity.

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.
