Zonazione e vitigni autoctoni nel sud della Basilicata: metodologie integrate per la caratterizzazione di ambienti di elezione di biotipi storici finalizzati a vini di territorio nella DOC “Terre dell’Alta Val d’Agri”

Abstract

[English version below]

I territori della DOC “Terre dell’Alta Val d’Agri”, a Sud della regione Basilicata, si caratterizzano per una elevata biodiversità autoctona autoselezionatesi su ambienti ecologicamente ben definiti, ed una storica tradizione viticola basata sulla coltivazione di alcuni di questi vitigni minori con peculiari caratteristiche enologiche.
Al fine di dare continuità ad una serie di azioni di ricerca volte a riqualificare il comparto viti-vinicolo della regione, è stata formulata una metodologia integrata per la valorizzazione congiunta di questi ambienti di coltivazione e dei biotipi su di essi selezionatosi.
Il progetto di ricerca si pone come obiettivo di evidenziare sia i fattori fisici e ambientali che qui hanno influenzato la selezione della vite, mediante applicazione di metodologie di analisi territoriale modificate a fini viticoli, sia le principali caratteristiche di questi biotipi.
Infatti i vitigni autoctoni storici e/o minori, rappresentano realtà viticole spesso marginali e pertanto a rischio di abbandono. La loro salvaguardia va oltre il significato della conservazione di una biodiversità a rischio di erosione e si identifica, invece, con la necessità di tutelare l’esistenza di sistemi produttivi complessi e tradizionali che si concretizzano in sistemi polifunzionali e con valenza culturale (Cirigliano P. et al,. 2007).
In conclusione, i risultati ottenuti con la metodologia adottata si pongono come possibile percorso di ricerca che integra la valorizzazione e conservazione dell’identità specifica di un territorio viticolo – zonazione viticola – con la salvaguardia della biodiversità autoctona ivi presente, rispetto a principi di sostenibilità ambientale dei modelli produttivi.

The territories of DOC “Terre dell’Alta Val d’Agri”, in the South of Basilicata region, are characterized by an high native biodiversity autoselected on environments ecologically well defined, and a historic wine tradition based on the farming of some of these minor vines with peculiar oenological characteristics. To continue the research activities that have the aim to qualify the viticultural area of the region, an integrated methodology has been formulated to improve the farming of these environments and of the biotypes selected on them. The research project has the aim to highlight both physical and environmental factors that here had influenced the grape-vine selection, through the application of territorial analysis methodologies modified for wine aims, and also to highlight the main characteristics of these biotypes. In fact the not “so big” native grape-vine fields (Cargnello G., 2006) often represent marginal realities and so they risk to be abandoned. Their safeguard go beyond the preservation of a biodiversity that risks to be eroded, that’s way it’s necessary to protect the existence of traditional and complex productive systems that can actually be considered multipurpose systems with cultural value (Barbera e Cullotta, 2007; Biasi e Botti, 2007; Larcher e Devecchi, 2007).
In conclusion the results obtained with this methodology can be considered a possible research course which integrate the valorisation and preservation of the specific identity of a grape vine field – grape vine zoning – with the safeguard of native biodiversity where it is present, regarding the principles of environmental sustainability of productive models.

Downscaling of remote sensing time series: thermal zone classification approach in Gironde region

In viticulture, the challenges of local climate modelling are multiple: taking into account the local environment, fine temporal and spatial scales, reliable time series of climate data, ease of implementation and reproducibility of the method. At the local scale, recent studies have demonstrated the contribution of spatialization methods for ground-based climate observation data considering topographic factors such as altitude, slope, aspect, and geographic coordinates (Le Roux et al, 2017; De Rességuier et al, 2020). However, these studies have shown questions in terms of the reproducibility and sustainability of this type of climate study. In this context, we evaluated the potential of MODIS thermal satellite images validated with ground-based climate data (Morin et al, 2020). Previous studies have been encouraging, but questions remain to be explored at the regional scale, particularly in the dynamics of the massive use of bioclimatic indices to classify the climate of wine regions. The results at the local scale were encouraging, but this approach was tested in the current study at the regional scale. Several objectives were set: 1) to evaluate the downscaling method for land surface temperature time series, 2) to identify regional thermal structure variations. We used weekly minimum and maximum surface temperature time series acquired by MODIS satellites at a spatial resolution of 1000 m and downscaled at 500 m using topographical variables. Two types of analyses were performed:

Fertility assessment in Vitis vinifera L., cv. Alvarinho

The Portuguese wine production is characterized by wide yield fluctuations, causing considerable implications in the economic performance of this sector. The possibility of predicting the yield in advance is crucial as it enables preliminary planning and management of the available resources. The present work aims to study and evaluate two different techniques for the assessment of vine fertility. vineyards.

Italy sweet revolution: how club grapes are transforming the table grape market

Italy is the leader table grape producer country in Europe and the eighth worldwide (OIV, 2021). The italian production area is sized at approximately 47,248 hectares with a production of 9.66 million quintals of grapes. Apulia and sicily are the main producing italian regions which collectively account for over the 90% of the italian production area (istat, 2022).

Regulation of terpene production in methyl jasmonate treated cell-cultures

Terpenes are responsible for flavors and aromas of grapes, however, they also protect from radiation, participate in biotic stress and antioxidant mechanisms. The phytohormone methyl jasmonate (MeJA) mediates many of these stress responses and has been associated with increased terpene content in berries. Here, we generated transcriptomic data of Vitis vinifera cv. ‘Gamay’ cells treated with MeJA (100 μM) and cyclodextrins (50 μM) to understand these responses. Ontology analysis revealed that up-regulated genes (URGs) were enriched in jasmonic acid biosynthesis and signaling terms, as expected. Inspection of transcription factors (TFs) among URGs allowed us to study uncharacterized TFs.

Chitosan from sustainable source: antimicrobial activity against undesirable yeasts for production of low-sulphite wine

The addition of sulphur dioxide (SO2) is the method traditionally used for wine stabilisation, due to its broad spectrum of action against unwanted microorganisms and its ability to prevent oxidative phenomena.
