Uve e vini in vulcaniti basiche anorogeniche dei lessini meridionali, impronta petrochimica e assimilazione di metalli pesanti

Abstract

[English version below]

Nel 2009 sono stati prelevati e analizzati mediante XRF (X-ray fluorescence) campioni di suolo, in vigneti sperimentali siti nelle province di Vicenza e di Ancona. Sono stati inoltre determinati in 2 campioni di mosto e 2 di vino delle varietà Verdicchio e Refosco dal peduncolo rosso, ed in 2 di uva Refosco dal peduncolo rosso, gli elementi in traccia mediante ICP-MS (Inductively coupled plasma-mass spectrometry). Lo studio ha consentito di definire la qualità di uva e vini, i rapporti caratteristici per ogni tipologia di suolo, e caratterizzare l’impronta geochimica in un ampio areale in cui le modeste differenze climatiche non influiscono sulle dinamiche di assimilazione. Sono state definite le relazioni fra matrice suolo e vino attraverso il confronto fra le concentrazioni dei metalli analizzati nelle varie matrici e varietà di uva.

In 2009, 18 samples of soils, coming from experimental vineyards in Vicenza and Ancona, were collected and analysed using XRF technique, to characterize major and minor element concentration. Moreover, 2 samples of must, 2 samples of wine (one of each varieties Verdicchio and Refosco dal peduncolo rosso) and 2 samples of grapes Refosco dal peduncolo rosso, were investigated using ICP-MS (Inductively coupled plasma-mass spectrometry) technique in order to define their trace elements concentrations. The aim of this study has been not only to characterize the quality of the grapes and the wines, but also to define the typical ratios between these two variable for each soils, and to outline geochemical fingerprints in a wide area where climatic differences have limited influence on the assimilation processes. The comparison of heavy metals concentrations between the several matrix and the varieties of grapes allow to define the relationship between soil matrix and wine.

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.
