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.

Un Système d’Informations à Références Spatiales sur le Vignoble. Un outil performant d’aide aux recherches sur la caractérisation des terroirs viticoles

The “Terroirs d’Anjou” project led by the Agronomy sector of the Vine and Wine Research Unit of the INRA center in Angers aims to characterize the viticultural terroirs in a study area which includes 29 municipalities in the Maine et Loire and cuts across the Anjou, Coteaux du layon and Coteaux de l’Aubance appellation areas.

Transforming the grapevine world through new breeding techniques

Climate change and environmental degradation are existential threats to europe and the world. One of the most important objectives is to reduce by 2030 the use and the risk of chemical pesticides and fertilisers, reducing nutrient losses and increasing organic farming. Grapevine (vitis spp.) is one of the major and most economically important fruit crops worldwide. It is characterised by high levels of genetic diversity, as result of natural genetic mutations, which are common in grapevines and further assisted by ongoing vegetative propagation.

Study of grape-ripening process variability using mid infrared spectroscopy

To obtain a quality wine, it is necessary to collect grapes in an optimal state of maturation, so the control of the ripening process is fundamental for the viticulturist.

Monitoring small-scale alcoholic fermentations using a portable FTIR-ATR spectrometer and multivariate analysis

Although some wine production processes still rely on post-production evaluation and off-site laboratory analysis, the new winemaking industry is aware of a need for a better knowledge of the process to improve the properties of the final product. Thus, more and more wineries are interested in incorporating quality-by-design (QbD) strategies instead of postproduction testing because of the possibility to early detect deviations in fermentation or any other wine process. This would allow to detect unwanted situations and eventually to ‘readjust’ the process, thus minimizing rejects.

Distribution of photosynthates towards the grapes: effects of leaf removal and cluster thinning applied before veraison in cv. Verdejo

The relationship between grape production and leaf surface is a highly debated aspect in terms of the impact it may have on the composition and quality of grapes, especially in areas that focus their cultivation on high-quality wine. In many occasions, the limitation of the unitary production level in these areas is claimed to be the main factor for achieving high quality levels in the wine, forgetting the importance of the source-sink relationship and other environmental factors and management of the canopy. Taking this consideration into account, this work seeks to know the response of the vine as a whole, and the individual shoot as well, to the application of various alternatives of leaves and clusters removal, carried out in the phase immediately before veraison, in cv. Verdejo, in Spain.
