Il sistema vigneto del Lago di Bolsena: caratterizzazione della produzione di Cannaiola di Marta

Abstract

[English version below]

Il comprensorio del Lago di Bolsena (VT) è un territorio ad elevata vocazione vitivinicola in cui il paesaggio della vite storicamente persiste e caratterizza la fisionomia dei luoghi. Qui gli agroecosistemi viticoli possiedono una valenza ecologico-ambientale, storico-culturale ed economica di rilievo. La ricerca condotta ha previsto la caratterizzazione della tipologia delle produzioni e degli ambienti di coltivazione di diversi vitigni locali, in particolare il vitigno autoctono Cannaiola di Marta, con l’obiettivo di salvaguardarne il valore biologico, valutarne la qualità in funzione dei microambienti di coltivazione e il ruolo nella definizione della fisionomia del paesaggio. Mediante indagine cartografica è stata condotta un’analisi diacronica a scala territoriale per evidenziare il ruolo dei vigneti nell’uso del suolo e nella definizione dell’ecomosaico ambientale. In vigneti rappresentativi dell’eterogeneità degli ambienti di coltivazione, il vitigno autoctono Cannaiola di Marta è stato caratterizzato con indagine ampelografia rispetto alla varietà certificata Canaiolo nero. La qualità della produzione è stata rapportata alla tipologia di suolo e alla variabilità fisiografica. Uno studio dell’architettura dei vigneti ha completato l’analisi dei modelli viticoli. I risultati ottenuti hanno evidenziato l’unicità della produzione della Cannaiola di Marta e la particolarità degli ambienti di coltivazione per una qualità superiore. E’ emerso il carattere di vulnerabilità di questa produzione dovuta alla frammentarietà dei vigneti, a fronte di un elevato valore storico-culturale degli impianti. Il sistema vigneto della Cannaiola di Marta si inserisce armonicamente in un ecosistema prezioso per la salvaguardia delle risorse ambientali e paesaggistiche di un territorio fra i più suggestivi del Lazio.

The northern part of the Lazio region, i.e. the area around the Lake of Bolsena, is highly vacated to grapevine production. Since the past, rural landscape has been characterized by vineyards, that represent still today a distinctive trait of this territory. Here vineyards exhibit economical, but also ecological, historical, biological and social functions. Nonetheless, vineyard surface is decreasing dramatically, with evident loss in biodiversity and landscape diversity. The study was carried out in order to characterized through a systemic approach the production of the local variety Cannaiola di Marta and its territorial contest. In order to preserve this production and the related landscape, the germplasm unicity was evaluated, the grape quality was tested in the highly differing physical environments, and the physionomy of the vineyards, as well as that of the rural landscape, was measured through cartographic elaboration. The research has proved that the investigated area is suitable for high quality and unique productions. It is also possible to attribute to these vulnerable vineyards a cultural significance, based on the employment of historic germplasm, on traditional vineyard traits and cultural practices. The viticulture of this territory is included in a equilibrated ecosystem, in which vineyards might preserve the environmental resources of one of the most agreeable territory of the Lazio region.

Exploring the contributions of terroir factors on berry quality of cvs. Cabernet-Sauvignon and Merlot (Vitis vinifera L.) at the Eastern Foothills of the Helan Mountains region of China

Terroir leaves its mark on the accumulation of flavours in grape berries, triggering biochemical re-actions and ultimately shaping wine styles.

Regenerative agricultural winegrowing systems play a role in refining the expression of terroir in the pacific coast region of United States and Canada

By definition, Regenerative Agricultural Systems seek to promote soil and plant health by using photosynthesis for the removal and retention of atmospheric carbon dioxide into stable soil carbon.

The interplay between water deficit and nitrogen and potassium nutrition in Vitis vinifera L.

Climate change is expected to provoke an increase in the frequency and intensity of drought events and water scarcity that will have detrimental effects on photosynthesis and plant yield. To sustain an appropriate plant yield under sub-optimal conditions, a common practice is the application of high amounts of fertilizers with negative environmental consequences. The present study aims at evaluating the interplay between water and nutrient availability, namely nitrogen (N) and potassium (K), in two grapevine cultivars with a different sensitivity to water shortage stress. Two-year-old Vitis Vinifera cv. Cabernet Sauvignon and Grenache grapevine plants grafted on SO4 rootstock have been transferred in pots under semi-environmental conditions.

Heat-stress responses regulated via a MYB24-MYC2 complex

Throughout the growing season, grapevine frequently encounters environmental challenges associated with heat and light radiation stress, especially during the ripening stage, thereby constraining the yield and quality of berries. MYB24 has been previously proposed to control light responses during late fruit ripening stages, and it has been found to require the co-factor MYC2. We have generated transcriptomic data from grapevine leaves transiently co-transformed with MYB24 and MYC2. Differential expression analysis revealed 179 up-regulated genes (URGs). Considering tissue specificity, where MYB24 is specifically and highly expressed in flowers and late-ripening berries, the expression of these URGs was explored using a previously published Berry Development Atlas gathering berry development data of cv. ‘Pinot Noir’ and ‘Cabernet Sauvignon’ in different vintages.

Déterminisme de l’effet terroir: influence de la surface foliaire primaire de la vigne en début de cycle sur le potentiel vendange

ln the Mid-Loire Valley, in France, for the fast twenty years a network of experimental plots has been used to analyse the terroir effect on the behaviour of the Cabernet franc variety of grape. The study of the primary leaf area (SFI) for several vintages shows that it differs greatly from one terroir to another.
