Il paesaggio delle alberate aversane ed il vino Asprinio

Abstract

[English version below]

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. I primi risultati indicano la totale omogeneità genetica della popolazione del vitigno ‘Asprinio’, non essendo stati ritrovati campioni vegetali riferibili a biotipi diversi. I saggi immunoenzimatici ELISA hanno rilevato la presenza di GLRaV 1, GLRaV 3 e GVA in tutti i campioni, mentre l’analisi delle molecole aromatiche delle uve e dei vini, condotta mediante analisi SPME-GC/MS, ha messo in evidenza che le uve ‘Asprinio’, prodotte sulla fascia più bassa delle alberate, presentano una maggiore potenzialità aromatica, rispetto a quelle della fascia più alta o delle controspalliere. I vini prodotti con diversi protocolli mostrano parametri enologici (grado alcolico, livelli di pH a acidità totale) simili tra di loro ed a quelli riportati da autori della metà del XX secolo.

During 2009, in some vineyards grown on trees (alberata) in the province of Caserta (Italy), a study is carried out to assess the genetic variability of the ‘Asprinio’ grapevine population, the health condition of the plants and the features of the wine in relation to the breeding system (traditional alberata vs horizontal training system) and to the heigth of fertile shoots. The first results point out the genetic identity of the ‘Aprinio’ grapevine population, because no different bio-types were found. The immunoenzymatic essays ELISA revealed that all the accessions were infected by GLRaV 1, GLRaV 3 and GVA; whereas the determination of the aromatic molecules from grapes and wines, performed by SPME- GC/MS analysis, indicated that the ‘Asprinio’ grapes, grown on lower area of the alberata, show greater aromatic potential than those from highest level of the same or those from vertical training system. The wines, produced by different procedures, show oenologycal parameters (alcohol degree, pH and total acidity level) similar to each other and to those reported by some authors of the mid-twentieth century.

INTENSE PULSED LIGHT FOR VINEYARD WASTEWATER: A PROMISING NEW PROCESS OF DEGRADATION FOR PESTICIDES

The use of pesticides for vine growing is responsible for generating an important volume of wastewater. In 2009, 13 processes were authorized for wastewater treatment but they are expensive and the toxicological impact of the secondary metabolites that are formed is not clearly established. Recently photodecomposition processes have been studied and proved an effectiveness to degrade pesticides and to modify their structures (Maheswari et al., 2010, Lassale et al., 2014). In this field, Pulsed Light (PL) seems to be an interesting and efficient process (Baranda et al., 2017). Therefore, the aim of this work was to investigate the PL technology as a new process for the degradation of pesticides.

Evaluation of intra-vineyard spatial and temporal variability of leaf area index using multispectral images obtained by satellite (Landsat 8, Sentinel-2) and unmanned aerial vehicle platforms

Estimation of vineyard leaf area index (LAI) is an important aspect for the winegrowers. However, tracking and monitoring are difficult tasks due to time constraints. Satellite and unmanned aerial vehicle (UAV) imaging have become a practical monitoring method for LAI. Nevertheless, for a proper LAI determination, the image’s spatial resolution is a key factor, since low-resolution images are incapable of distinguishing between adjacent vines due to the large area covered in each pixel, this leads to misinterpretation or generalisation of vineyard information.

Validation of phenological models for grapevine in the Veneto region

In this study we have compared the predictive ability of two phenological models: a traditional Thermal Time (TT) and a version of the more recently develop Unified Model (UM).

How climate change can modify the flavor of red Merlot and Cabernet-Sauvignon

he main goal of this research was to identify key aroma compounds linked with the maturity of grapes (ripe and overripe) and involved in grapes and wines with an intense dried fruits aroma. Odoriferous zones reminiscent of these aromas were detected by gas chromatography coupled with olfactometry (GC-O).

Increasing microalgae biomass feedstock by valorizing wine gaseous and liquid residues

Global warming due to greenhouse gases (GHG) has become a serious worldwide concern. The new EU Green Deal aims t0 achieve GHG emissions reduction by at least 55% by 2030 and a climate neutral EU economy by 2050. The deal strongly encourages GHG reducing measures at local, national and European levels. The REDWine project will demonstrate the technical, economic and environmental feasibility of reducing by, at least, 31% of the CO2 eq. emissions produced in the winery industry value chain by utilizing biogenic fermentation CO2 for microalgae biomass production
