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.

Climate and the evolving mix of grape varieties in Australia’s wine regions

The purpose of this study is to examine the changing mix of winegrape varieties in Australia so as to address the question: In the light of key climate indicators and predictions of further climate change, how appropriate are the grape varieties currently planted in Australia’s wine regions? To achieve this, regions are classified into zones according to each region’s climate variables, particularly average growing season temperature (GST), leaving aside within-region variations in climates. Five different climatic classifications are reported. Using projections of GSTs for the mid- and late 21st century, the extent to which each region is projected to move from its current zone classification to a warmer one is reported. Also shown is the changing proportion of each of 21 key varieties grown in a GST zone considered to be optimal for premium winegrape production. Together these indicators strengthen earlier suggestions that the mix of varieties may be currently less than ideal in many Australian wine regions, and would become even less so in coming decades if that mix was not altered in the anticipation of climate change. That is, grape varieties in many (especially the warmest) regions will have to keep changing, or wineries will have to seek fruit from higher latitudes or elevations if they wish to retain their current mix of varieties and wine styles.

Fruit set rate clonal variation explains yield differences at harvest in Malbec

Malbec is Argentina’s flagship variety, and it is internationally recognized for producing high-quality red wines. Fruit set rate is a major component in grapevine yield determination, and it is the outcome of multiple genetic and environmental interacting variables. Here, we characterized the reproductive performance of 25 Malbec clones grown under homogeneous conditions in a 23-years old experimental plot. We measured traits near flowering (like the number of flowers per inflorescence) and at harvest (including the number of berries per cluster and berry weight), during two consecutive seasons (2022 and 2023).

Influence of cover crops in a Tempranillo vineyard grown under the edaphoclimatic conditions of the Appellation of Origin Rueda

The way to manage the vineyard soils has certainly changed in Spain during the last years. Traditionally, the vineyards were tilled, but this growing technique has been replaced in some vineyards by the bare soil with herbicide

Under-vine cover crops in viticulture: impact of different weed management practices on weed suppression, yield and quality of grapevine cultivar Riesling

The regulation of weeds, particularly in the under-vine area of grapevines, is essential for the maintenance of grape yield and quality.

Post-plant nematicide timing for northern root-knot nematode in Washington wine grapes

Vigor declines in older vineyards and poor vine establishment in replant situations have been attributed to plant-parasitic nematodes. The northern root-knot nematode, Meloidogyne hapla, is the most prevalent plant-parasitic nematode species found in Washington wine grape vineyards. Management for nematodes in established vineyards is limited to the application of post-plant nematicides. We are evaluating new nematicides that are currently not registered in grape for their efficacy in controlling M. hapla and a part of that evaluation includes improving the alignment of nematicide application timing with the vulnerable second-stage juvenile (J2) life stage of M. hapla.
