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.

A phylogenomic study reveals the major dissemination routes of ‘Tempranillo Tinto’ in the Iberian Peninsula

‘Tempranillo Tinto’ is a black-berried Iberian cultivar that originated from a hybridization between cvs. ‘Benedicto’ and ‘Albillo Mayor’ [1]. Today, it is the third most widely grown wine grape cultivar worldwide with more than 200,000 hectares of vineyards mostly distributed along the Iberian Peninsula, where it is also known as ‘Cencibel’, ‘Tinta de Toro’, ‘Tinta Roriz’, and ‘Aragonez’, among other synonyms. Here, we quantified the intra-varietal genomic diversity in this cultivar through the study of 35 clones or ancient vines from seven different Iberian wine-making regions. A comparative analysis after Illumina whole-genome sequencing revealed the presence of 1,120 clonal single nucleotide variants (SNVs).

Influence du terroir et de la conduite du verger sur la vigueur, le développement et la productivité des pommiers. Conséquences sur la teneur en sucres des pommes

Dans le cadre d’une étude globale de l’influence du type de sol et de la conduite du verger sur la composition des pommes à cidre, une attention particulière est portée sur les facteurs amonts de la qualité comme

Application of regenerative agriculture to viticulture: The REVINE project

Conventional viticulture improved the quality of production, but the economic costs can be unsustainable. Today, producers need to consider consumers’ demands for healthy, eco-friendly products. Institutions promote sustainable agriculture, with regenerative agriculture being the latest generation of methodologies focused on recovering losses and ensuring future sustainability. The revine project studies regenerative agricultural technology applied in mediterranean countries to provide precise indications for soil processing and effective vineyard treatments.

Correspondence between physiological plant variables and carbon isotope composition in different climate winegrape regions

The climate is the environmental factor that contributes with greater weight in the variability of the yield and the composition of the grape, therefore, it is key in the determination of the typicity of the product. Of the environmental factors, the evolution of water availability conditions, among other things, the biochemical evolution of the compounds of the grape and the type of wine to be elaborated. An integrating parameter of the hydric state of the plant is the carbon isotopic composition (δ13C). This indicator is a useful parameter to characterize the water status during the maturation period and estimate the transpiration efficiency or water use efficiency (EUA) in the vine.

Application of Hyper Spectral Imaging for early detection of rachis browning in table grapes

Rachis browning is a common abiotic stress that occurs during postharvest storage, leading to a decrease in commercial value of table grapes and resulting in significant economic losses. Its early detection could enable the implementation of preventive strategies. In this report, we show the feasibility of a non-destructive early detection of browning based on Hyper Spectral Imaging (HSI). Furthermore, rachis samples were subjected to transcriptomic analysis to understand putative pathways causing differences in browning within varieties.
