Sviluppo di una metodologia di tracciabilità e definizione dell’impronta petrochimica in suoli e vini della Sicilia occidentale nella piana di Marsala (TP)

Abstract

[English version below]

I risultati delle ricerche condotte in un vigneto sperimentale di Marsala (TP), scelto per omogeneità di fattori bio-agronomici (età, tecniche colturali, potenzialità vegetativa e produttiva), consentono di definire l’impronta geochimica in uve e vini ereditate dai suoli. Ai fini della ricerca sono stati prelevati 24 campioni di suolo – 6 per ogni varietà – in corrispondenza degli apparati radicali delle quattro cultivars indagate: Nero D’Avola, Refosco dal peduncolo rosso, Fiano e Verdicchio. I suoli sono stati caratterizzati mediante analisi chimiche in XRF (X ray Fluorescence) ed i vini in ICP-MS (Inductively Coupled Plasma-Mass Spectrometry).
La piana di Marsala rappresenta, infatti, un’area test ideale per la tipologia di suolo e per la presenza, nell’alta pianura, di un acquifero di buona qualità attualmente non degradato per fenomeni di salinizzazione. L’area inoltre ricade nella fascia sensibile alla desertificazione che è da alcuni anni oggetto di indagine tramite numerosi progetti e programmi di ricerca, ed il monitoraggio delle caratteristiche di uve e vini nelle varie annate può fornire un contributo alla comprensione di questi effetti. L’analisi delle varie cultivars è focalizzata alla ricerca dei vitigni meno sensibili allo stress climatico al fine di pianificare interventi di qualificazione in grado di affrontare l’impatto che i cambiamenti climatici produrranno nei prossimi anni nell’area mediterranea. Questo lavoro ha cercato di definire i tenori di fondo dei macro e micronutrienti inorganici e di acquisire la banca dati essenziale per la valutazione delle ricadute dei cambiamenti climatici e degli effetti della desertificazione sulla qualità dei vini.

Research studies carried out on a vineyard, selected on the basis of the bio-agronomic factors’ homogeneity (age, cultivation techniques, production capability…), in the Marsala Plain (TP) Sicily, have permitted to define geochemical fingerprints inherited by grapes and wines. 24 soil’s samples (gathered in correspondence of the root system) of 4 different cultivar types (6 from Nero D’Avola, 6 from Refosco dal peduncolo rosso, 6 from Fiano and 6 from Verdicchio) were collected. The soil samples were characterized by XRF chemical analysis and the wine samples were analysed by ICP-MS technique.
The Marsala Plain is test site both for soils and for the presence of an aquifer characterized by good quality of water and lack of salinisation processes. These pilot site is located in an area currently interested by desertification phenomena and for this reason carefully monitored. This situation can be helpful in order to characterize the features of grapes and wines in several vintage years contributing on the comprehension of the effects of desertification on the production of wine. Analysis of different cultivar were focused on the definition of particular grapevine varieties less sensitive to climatic stress conditions, in order to plan suitable qualification actions to face the impact of climatic changes foreseen in the Mediterranean area.
The aim of this study is to define the background standard values for inorganic macro and micronutrients, acquiring
the essential data set useful for the evaluation of climatic changes and desertification effects on the wine quality.

Eugenol:  a new marker of hybrid vines? The case study of Baco Blanc in Armagnac

Nowadays, winemaking is dealing with great challenges, notably climate change, disease resistance and low pesticide inputs, desire for more sustainable agricultural productions and permanent changing of consumer preference. Trying to propose practice improvements, scientists are exploring vine hybridization a paradoxically old but still actual way to take up such challenges

Contribution of phenolic compounds to the total antioxidant capacity of Pinotage wine

The South African wine industry is taking an interest in the enhancement of red wine total antioxidant capacity (TAC) with retention of sensory quality to satisfy the demands of increasingly discerning consumers. The focus is especially on the unique South African red wine cultivar, Pinotage.

VviSOC1a and VviAG1 act antagonistically in the regulation of flower formation

The SUPPRESSOR OF OVEREXPRESSION OF CONSTANS1 (SOC1) is a key floral activator that coordinates external and internal stimuli to ensure timely flowering. During early stages of flower formation, SOC1 represses floral organ identity genes such as AGAMOUS (AG) to prevent premature organ differentiation. In addition to floral organ specification, AG has been shown to regulate fleshy fruit expansion and ripening and, as such, is an important contributor to fruit quality traits. Currently, little is known about the function and gene regulatory network of the grapevine homologs VviSOC1a and VviAG1. As such, the aim of this study was to functionally characterise both genes by overexpressing them in tomato and performing phenotypic and gene expression studies.

Iso-/anisohydric behavior in wine grapes may be a matter of soil moisture

There are claims that wine grape cultivars are either isohydric or anisohydric; the former maintaining, and the latter decreasing, their plant water status as soil moisture declines. However, available information is inconsistent. There are those that show an existence of a continuum in cultivar response to soil moisture rather than a distinct categorization. Others even show both behaviors in the same cultivar grown in different environments. In this study we investigated the behavior of 30 own rooted Vitis vinifera cultivars during successive drydown and rewatering cycles over two growing seasons in arid eastern Washington (<200 mm annual precipitation).

Evidence of successful wine business strategies: customer acquisition, value or retention?

This presentation illustrates a series of successful wine businesses, which have managed to counter the downward trend impacting the global industry. How these businesses have been successful is explained through the planning and execution of strategies that focused on a clear and consistent aim in attracting new consumers. These cases add weight to the ehrenbergian position that for a business to be successful it must target new customers as a priority over alternative options like increasing value or improving customer retention.
