Effects of postharvest partial dehydration and prolonged treatments with ethylene on transcript profiling in skins of wine grape berries.
2010
For certain food products, postharvest controlled stresses or treatments with specific elicitors are applied to induce desired physical/chemical changes and/or to positively affect phytochemical content. This is the case of wine grapes where both strategies, singularly applied or coupled, can be used to modulate berry composition and, as a consequence, affect wine quality traits. Since the knowledge of the effects of these postharvest treatments on berry metabolism and the regulation of gene expression is very limited, a large-scale transcriptome analysis has been carried out, using an oligo-based microarray (14,562 probes) on skins of wine grape (Vitis vinifera L.) berries subjected to deh…
Le goût moisi-terreux du vin : contribution à la caractérisation cinétique et métabolique des moisissures associées à ce défaut organoleptique
2011
Some microorganisms that co-exist on the grapevine may have beneficial effects on the quality of wine whereas others may be at the origin of organoleptic deviations. In the last decade, several mouldy or earthy odors have been highlighted in various wine regions from France. (-)-geosmin was found to be the major compound responsible for this deviation, along with Botrytis cinerea and fungi belonging to the genus Penicillium, since they were frequently isolated from “earthy-musty” odor grapes. The extent of damage on the quality of wines, motivated our study on the caracterisation of grape rot fungi. First of all, the microflora of grapes from Burgundy vineyards was identified (morphological…
Giant reed as energy crop for Southern Italy: An economic feasibility study
2016
Abstract Among renewable sources giant reed has attracted a growing interest as energy crop especially in Southern Europe, thanks to its low agronomic input requirements. This paper aimed at evaluating the economic feasibility of introduction of giant reed plantation as energy crop in the Southern Italy. In particular, an economic and financial analysis was performed by comparing giant reed (both for woodchip and chopped forage production) with traditional crops (pluriannual and annual) that are currently cultivated in the same area, such as wine grape, melon and tomato. Results showed the highest profitability of giant reed respect to other crops with current market prices. In particular, …
