Comparison of the free radical-scavenging activity in infected oidium and sound dolcetto grape cultivar grown in a terroir of Central Italy

The importance of polyphenols, which are present in many vegetables and grapes too, is well-know and documented. Specific research works about the red grape and its derivative juices and wines show that the antioxidant and/or antiradical activities are directly correlated with the complex polyphenol matrix. The content of polyphenols in grapes is clearly affected by […]

Un modello di lavoro per lo studio dell’ up-grading tecnologico del vigneto nel Veneto Occidentale. Connettività degli attori e mappatura su dati avepa integrati con rilevamento speditivo e qualitativo

[English version below] Il lavoro si prefigge di esaminare la propensione alla modernizzazione della viticoltura del Veneto Occidentale, letto attraverso la diffusione di forme di allevamento a sviluppo contenuto. L’integrazione dell’analisi qualitativa con quella statistica e cartografica – su dati forniti dall’Agenzia Veneta per i Pagamenti in Agricoltura (AVEPA) – ha permesso di identificare il […]

Le aree viticole storiche nel mondo: i loro vitigni, la loro protezione e la tipicità dei vini in esse ottenuti

Il tema da trattare si riferisce ai vari ecosistemi viticoli mondiali, ovviamente non facilmente sintetizzabili in una relazione. Sostanzialmente si richiama, pertanto, ai terroirs. La definizione di terroir comprende i fattori naturali (vitigno, clima, suolo) e quelli antropici (pratiche viticole e enologiche) (fig. 1).Nella prima parte della relazione si esaminerà la diffusione del vitigno nel […]

Evaluation of Valdadige DOC “Terra dei Forti” vineyards by zoning approach

[English version below] La conoscenza dell’interazione genotipo x ambiente e pertanto della caratterizzazione territoriale è di prioritaria importanza nella valutazione dei siti. Grazie alla combinazione di dati GIS spazializzati con quelli viticoli (zonazione) si può aggiornare il concetto di “terroir” ottimizzando la produzione di vini caratterizzati da alta tipicità.Al fine di aumentare la conoscenza dell’area […]

La viticulture durable: concept et application aux terroirs viticoles

Evoquer la notion de durabilité pour la vigne, plante multimillénaire, et le vin, tous deux intimement liés aux origines de notre civilisation, peut paraître un non-sens. Le vin revêt en effet une dimension culturelle, voire cultuelle intemporelle, qui recouvre tout à la fois les sciences, les savoir-faire ancestraux, la sociologie, les religions. Notre filière a […]

The ability of wine yeasts fermenting by the addition of exogenous biotin

Research is focused on the increase of the field of obtaining the wine yeast, under physical and chemical conditions. Study of different influences on yeast production is very important for the promotion of new cultivation methods for increasing both the fermentative and conservation capacity.The present article deals with the study of biotin activity on the […]

Comparative studies on the dynamics of fermentation of selected wine yeasts

Alcoholic fermentation is an anaerobic biochemical process of oxidation-reduction in which carbohydrates are metabolized by the action of yeast enzymes in major products (ethylalcohol and carbon dioxide) and minor products (superior alcohols, aldehydes, acetic acid, glycerol, volatile acids and others). Typical agents of the alcoholic fermentation are from Saccharomyces genus, by fermentation resulting concentrations in […]

Adjustments of water use efficiency by stomatal regulation during drought and recovery of Verona province grape varieties grafted on two different vitis hybrid rootstocks

Drought is considered to be the predominant factor both for determining the geographic distribution of vegetation and for restricting crop yields in agriculture. Furthermore, water stress is a limiting factor for a wide range of plant physiological processes and can have a profound effect on plant metabolism and development. Drought stress can decrease the sensitivity […]
