Old but gold: the interest for minor grapevine varieties – a case study in the Veneto region (Italy)

Abstract

The biodiversity of cultivated vines has been significantly reduced due to a series of factors that have favoured the cultivation of a limited number of varieties and clones over time. In veneto, since 1980, a series of important actions have been implemented to counter this process. These actions have focused on the conservation of germplasm identified in the territory and the recovery of varieties historically present in the region, which were in danger of being abandoned and disappearing. An analysis of the regional wine-growing areas between 2017 and 2023 reveals a notable increase in the cultivated area dedicated to these minor varieties. This indicates a growing interest among winegrowers in enhancing production diversity by focusing on these varieties. Despite the relatively limited cultivated area, some varieties have experienced a significant expansion, with more than double the area cultivated in 2017. For example, the cultivated area of ‘recantina’ increased by 14.4 hectares (157%) and that of ‘grapariol’ by 12.8 hectares (137%). These varieties, historically associated with the veneto wine-growing tradition, remain relevant today and can produce high-quality wines linked to specific terroirs of the region. This scenario serves to exemplify the tangible advantages that can be derived from the conservation and study of agro-biodiversity.

L’interesse per i vitigni minori – un caso di studio nella regione veneto (Italia)

La biodiversità della vite coltivata ha subito una significativa riduzione a causa di una serie di fattori che hanno favorito nel tempo la coltivazione di un numero ristretto di varietà e cloni. In veneto, a partire dal 1980, sono state realizzate una serie di importanti azioni per contrastare questo processo. Le azioni sono state focalizzate alla conservazione del germoplasma identificato nel territorio e al recupero di varietà storicamente presenti nella regione, che rischiano di essere abbandonate e di scomparire. Un’analisi delle aree viticole regionali nel periodo 2017-2023 mostra un chiaro incremento della superficie coltivata con queste varietà. Ciò evidenzia l’interesse dei viticoltori ad aumentare la diversificazione della produzione puntando su questi vitigni. Sebbene la superficie coltivata rimanga a un livello relativamente basso, alcune varietà hanno più che raddoppiato la loro superficie. Ad esempio, la superficie coltivata a “recantina” è aumentata di 14,4 ettari (157%) e quella a “grapariol” di 12,8 ettari (137%). Queste varietà, storicamente associate alla tradizione vitivinicola del veneto, sono ancora attuali e capaci di produrre vini di alta qualità legati allo specifico terroir della regione. Questo quadro fornisce un buon esempio dei benefici diretti che possono derivare dalla conservazione e dallo studio dell’agro-biodiversità.

L’intérêt pour les cépages mineurs– une étude de cas dans la région de Vénétie (Italie)

La biodiversité des vignes cultivées s’est considérablement réduite en raison d’une série de facteurs qui ont favorisé la culture d’un nombre limité de cépages et de clones au fil du temps. En vénétie, depuis 1980, une série d’actions importantes ont été mises en œuvre pour contrer ce processus. Ces actions se sont concentrées sur la conservation du matériel génétique identifié sur le territoire et sur la récupération des variétés historiquement présentes dans la région, qui risquaient d’être abandonnées et de disparaître. L’analyse des surfaces viticoles régionales entre 2017 et 2023 révèle une augmentation notable de la surface cultivée consacrée à ces variétés mineures. Cela témoigne de l’intérêt croissant des viticulteurs pour l’amélioration de la diversité de la production en se concentrant sur ces variétés. Bien que la superficie cultivée soit encore relativement limitée, certaines variétés ont beaucoup évolué, faisant plus que doubler la superficie cultivée en 2017. Par exemple, la superficie cultivée de « recantina » a augmenté de 14,4 hectares (157 %) et celle de « grapariol » de 12,8 hectares (137 %). Ces cépages, historiquement associés à la tradition viticole de la vénétie, restent d’actualité et sont capables de produire des vins de grande qualité liés aux terroirs spécifiques de la région. Ce scénario illustre les avantages concrets qui peuvent découler de la conservation et de l’étude de l’agro-biodiversité.

Evaluation of spraying effects of plant protection unmanned aerial vehicle on two different training systems of vine in Northeast China

In recent years, the application of plant protection unmanned aerial vehicle (UAV) in agricultural pest control has become more and more popular. However, there are few reports about the application of plant protection UAV for wine grapes, and there are no studies comparing the spraying effect of plant protection UAV with that of manual operation in vineyards. In this context, the objective of this study was to explore the feasibility of using plant protection UAV in vineyards instead of manual operations by evaluating the effectiveness of UAV spray in two common grape training systems in Northeast China.

Three new Apulian seedless varieties available for the table grape supply chain

The table grape industry in Europe is undergoing significant changes. For instance, in Italy, the national register of vine varieties was established in 1969, and since then, many varieties of table grapes have been registered. In the first thirty years, from 1969 to 1999, 62 seeded and 24 seedless varieties were registered. In the subsequent period, from 2000 to the present day, 23 seeded varieties and 99 seedless varieties were registered.

Generation of radicals in wine by cavitation and study of their interaction with metals, phenols and carboxylic acids

High-power ultrasounds have been related to an accelerated aging of wines, an effect that has been associated to the formation of radical species caused by the cavitation phenomenon [1]. This phenomenon consists of the formation of bubbles in the liquid medium that, when they collapse, cause high-pressure hot spots and temperatures of up to 4800 k [2], notably increasing the reactivity in the medium.

Gestión de la mitigación por las empresas vitivinícolas: combinar sostenibilidad y rentabilidad

The transition to a decarbonized economy requires companies to adopt mitigation measures. The wine sector is one of the most affected by climate change and, therefore, interested in its mitigation. The question is how this process develops. To address this, we build on a previous study [1], which identified different types of Spanish wineries based on their sustainability approach.
