Evaluation of winegrape anthocyanins in the vineyard using a portable fluorimetric sensor: seasonal and water regime effects

Abstract

Accumulation of anthocyanins (Anth) on whole winegrape (Vitis vinifera L.) bunches attached to the vine was monitored by a fluorescence-based sensor (Multiplex) on ‘Aleatico’ and ‘Nero d’Avola’. Different water regimes wereapplied. The Anth index (ANTH) provided by the Multiplex sensor was able to detect a shift in the berry ripening curve of ‘Aleatico’ between two consecutive seasons: it was at least one week anticipated in 2009 with respect to 2008, as also confirmed by the visual estimation of veraison onset and by the time evolution of technological maturity. For both cultivars under different water regimes, the ANTH index indicated that in plants under water stress the rate of Anth accumulation was increased with respect to those undermoderate water deficit. The Multiplex sensor resulted to be an useful device for the rapid and non- invasive estimation of Anth in the vineyard.

Postharvest elicitors and metabolic changes in wine grape berries

Wine grape berries respond to postharvest treatments with specific gaseous elicitors in terms of metabolic changes and composition. Short-term (3 days) high (30 KPa) CO2 treatment affects phenol compound concentration in skins of ‘Trebbiano toscano’ berries.

Terroir aspects of harvest timing in a cool climate wine region: physiology, berry skin phenolic composition and wine quality

Preliminary experiment of harvest timing was carried out in Eger wine district, Hungary in 2009. In situ physiological responses, berry quality parameters and wine quality of the Kékfrankos grapevine were studied at two growing sites (Eger-K6lyuktet6 – non-stressed, flat vineyard, and Eger-Nagyeged hill – water stressed, steep slope vineyard).

Relevance of an immunoassay test for rapid detection of Botrytis cinerea in ‘Ugni blanc’ musts and wines

A new immunoassay kit, called Botrytis Lateral Flow Device has been tested to detect Botrytis cinerea on musts and wines. The comparison of the immunoassay result with the quantitative analysis of usual markers (gluconic acid, sugars and polyols) showed the relevance of this innovative tool.
