Analysis of climate spatio-temporal variability in the Conegliano-Valdobbiadene DOCG wine district

Abstract

Local climate characterization is fundamental in terroir description, yet global change perspectives raise questions about its feasibility, since temporal stability cannot be no more assumed for the forthcoming years.
The objective of this work was to gain a better understanding of the climatic spatio-temporal variability of a grapevine growing area, and how this has changed during recent times.
Using as a case-study the Conegliano-Valdobbiadene DOCG wine district in North-Eastern Italy, we developed a methodology to downscale daily mean air temperature from the European Climate Assessment gridded dataset (E-OBS), to derive daily temperature surfaces at 500m spatial resolution. This allowed to analyse how the spatio-temporal variability affected grapevine phenology in the last 60 years.
The main results showed that, respect to the 1950-1979 period, the average Winkler index between 1980 and 2008 showed a +184 °C increase, with little spatial variation, as well as for the estimated dates for the main phenological events, which showed a generalized anticipation of about 2 to 5 days. More pronounced changes were observed on the interannual variability, which showed increases in both the average values and pattern of distribution.

Agroclimatic characterisation of the Portugese wine denominations of origin using a compound index

Aims: This study aims to: (1) characterize the agroclimatic conditions of the Portuguese Denominations of Origin, using a compound index that combines thermal and soil water balance conditions and a high-resolution climatic dataset (~1 km spatial resolution); (2) categorize the main grapevine varieties as a function of this compound index.

Биотехнология в системе оздоровления и размножения комплексно-устойчивых сортов винограда на Юге России

The production of certified grape planting material is one of the most important problems in the Russian federation. According to the scheme for the production of healthy grape planting material, before being introduced into in vitro culture, the source plants of each variety (Moldova, Augustin, Bart) were individually assessed for typical varietal characteristics and the presence/absence of symptoms of infection by pests.
