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.

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.
