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.

Physiological and growth reaction of Shiraz/101-14 Mgt to row orientation and soil water status

Advanced knowledge on grapevine row orientation is required to improve establishment, management and outcomes of vineyards on terroirs with different environmental conditions (climate, soil, topography) and in view of a future change to more extreme climatic conditions. The purpose of this study was to determine the combined effect of row orientation, plant water status and ripeness level on the physiological and viticultural reaction of Shiraz/101-14 Mgt.

Effects of mechanical leafing and deficit irrigation on Cabernet Sauvignon grown in warm climate of California

San Joaquin Valley accounts for 40% of wine grape acreage and produces 70% of wine grape in California. Fruit quality is one of most important factors which impact the economical sustainability of farming wine grapes in this region. Due to the recent drought and expected labor cost increase, the wine industry is thrilled to understand how to improve fruit quality while maintaining the yield with less water and labor input. The present study aims to study the interactive effects of mechanical leafing and deficit irrigation on yield and berry compositions of Cabernet Sauvignon grown in warm climate of California.

The effects of cane girdling on berry texture properties and the concentration of some aroma compounds in three table grape cultivars

The marketability of the table grapes is highly influenced by the consumer demand; therefore the market value of the table grapes is mainly characterized by its berry size, colour, taste and texture. Girdling could cause accumulation of several components in plants above the ringing of the phloem including clusters and resulting improved maturity. The aim of the experiments was to examine the effect of girdling on berry texture characteristics and aroma concentration.

Application of a fluorescence-based method to evaluate the ripening process and quality of Pinot Blanc grape

The chemical composition of grape berries at harvest is one of the most important factors that should be considered to produce high quality wines. Among the different chemical classes which characterize the grape juice, the polyphenolic compound, such as flavonoids, contribute to the final taste and color of wines. Recently, an innovative non-destructive method, based on chlorophyll fluorescence, was developed to estimate the phenolic maturity of red grape varieties through the evaluation of anthocyanins accumulated in the berry skin. To date, only few data are available about the application of this method on white grape varieties.

Different yield regulation strategies in semi-minimal-pruned hedge (SMPH) and impact on bunch architecture

Yields in the novel viticulture training system Semi-Minimal-Pruned Hedge (SMPH) are generally higher compared to the traditional Vertical Shoot Positioning (VSP). Excessive yields have a negative impact on the vine and wine quality, which can result in substantial losses in yield in subsequent vintages (alternate bearing) or penalties in fruit quality. Therefore yield regulation is essential. The bunch architecture in SMPH differs from VSP. Generally there is a higher amount but smaller bunches with lower single berry weights in SMPH compared to VSP.
