Determinazione della frazione aromatica dei vini, quale strumento per-la valorizzazione del territorio viticolo

Abstract

[English version below]

La caratterizzazione della frazione volatile aromatica dei vini attraverso l’analisi quali­quantitativa dei diversi composti, ha portato corne primo risultato la netta differenziazione delle annate in prova.
Dalla relazione tra analisi sensoriale e analisi chimica, è poi risultato che, per il vino Soave, esteri etilici e acetati sono i composti organoletticamente più importanti e responsabili del-l’aroma fruttato floreale. Alcoli e acidi sono apparsi invece meno utili e sicuri nella caratte­rizzazione varietale e ambientale. E’ quindi importante per ogni vino conoscere i composti aromatici tipici e i loro responsabili analitici, sulla base poi della quantificazione di questi ultimi sarà possibile una caratterizzazione ambientale.

The qualitative and quantitative analysis of the volatile aromatic components of wine has produced, as a first result, a net differentiation of the years being tested.
From the correlation between sensory and chemical analysis we have also found , for Soave wine, that acetates and esters are the most important sensory components; they are responsable for the fruit and floral aromas of wine.
However, alcohols and acids have shown to be less useful in varietal and environmental characterization. It is therefore very important to know, for each wine, the typical aromatic compounds and their chemical composition, and based on their quantification it is possible to value the environment.

Response of different grapevine cultivars to water stress using a hydroscape approach

Viticulture worldwide is currently affected by the effects of climate change. This set of adverse phenomena lead to a deterioration of functional vine mechanisms, affecting growth, physiology and grape ripening, which may cause severe losses with respect to yield and quality. To prevent water stress and other abiotic factors from severely affecting its physiology, the vine’s response is to reduce transpiration and photosynthesis rates. This response varies depending on the cultivar and its ability to adapt to the environment. The hydroscape method is based on the internal regulation of water status in the plant. It has been recently used to classify grapevine genotypes according to their iso/anisohydric behavior when they are subjected to water stress conditions.

The invasive seaweed Rugulopteryx okamurae: an innovative plant protective extract

Grapevine downy mildew, caused by Plasmopara viticola, is a devastating disease worldwide. Most commercially important cultivars of the European grapevine are highly susceptible and therefore require the recurrent application of synthetic fungicides to control the disease, copper being the most frequently used. However, with European Union goals to lower their usage, there is a need to develop innovative and sustainable strategies. In this respect, seaweeds have proven to have great potential as phytosanitary agents, in addition to promoting plant growth and stress-tolerance.

The use of remote sensing for intra-block vineyard management

L’unité de gestion technique d’un vignoble est aujourd’hui la parcelle. Néanmoins, au sein d’une même parcelle, la variabilité de l’expression végétative et de la constitution des raisins à maturité, peut être grande, en particulier à cause d’une hétérogénéité du sol.

Il paesaggio delle alberate aversane ed il vino Asprinio

Nel corso del 2009, in alcuni vigneti allevati ad alberata in provincia di Caserta (Italia), è stata avviata una ricerca per valutare la variabilità genetica della popolazione del vitigno ‘Asprinio’, la condizione sanitaria delle piante e le caratteristiche del vino sia rispetto alla forma di allevamento (alberata tradizionale e controspalliera) che all’altezza della fascia produttiva.

The importance of rural extension and advisory services to achieve a sustainable viticulture in a climate change scenario

A healthy and dynamic agricultural sector is an important foundation of rural development, generating strong bonds to other economic sectors.
