Leaf elemental composition in a replicated hybrid grape progeny grown in distinct climates

Abstract

The elemental composition (the ionome) of grape leaves is an important indicator of nutritional health, but its genetic architecture has received limited scientific attention. In this study, we analyzed the leaf ionome of 131 interspecific F1 hybrid progeny from a Vitis rupestris (♀) X Vitis riparia (♂) cross. The progeny were replicated in New York, South Dakota, Southwest Missouri ad Central Missouri, and the concentration of 20 elements were measured in their leaves at three different phenological stages during the growing season. In leaves collected at the apical node at anthesis, elemental concentrations correlated in a consistent manner (p < 0.05) across all four geographic locations. In subsequent phenological stages, elemental ratios in the apical-node leaves remained consistent across the South Dakota and New York sites, but not across the Missouri sites. In leaves collected at the basal and middle nodes, correlations varied greatly across all locations. Varimax-rotated PCA performed on the leaf ionome separated the two Missouri vineyards from their New York and South Dakota counterparts, even though the first two principal components accounted for only 27.8% of the variance. Using a GBS-based linkage map and the concentration of individual elements as phenotype, we were able to map nine QTL which could be detected at more than one vineyard locations. We were also able detect a QTL when we applied ionomic profile-derived PC1 scores as phenotype. Interestingly, this PCA-derived QTL mapped to the same locus as the QTL for potassium concentration.

Terroir aspects of harvest timing in a cool climate wine region: physiology, berry skin phenolic composition and wine quality

Preliminary experiment of harvest timing was carried out in Eger wine district, Hungary in 2009. In situ physiological responses, berry quality parameters and wine quality of the Kékfrankos grapevine were studied at two growing sites (Eger-K6lyuktet6 – non-stressed, flat vineyard, and Eger-Nagyeged hill – water stressed, steep slope vineyard).

Aceto Balsamico Tradizionale di Modena” PDO authenticity: detection of caramel-containing vinegar by HS-GC-IMS

Balsamic vinegars of Modena (Italy), namely Aceto Balsamico di Modena PGI (AB PGI) and Aceto Balsamico Tradizionale di Modena PDO (ABT PDO) are among the most important geographical indication products for Italy. ABT PDO, despite its very limited production, is recognized as one of the most representative Italian artisan gastronomic products, and it is known and commercialized all around the world. The economic value of ABT PDO (“affinato” and “extra-vecchio” types, depending on the aging), prepared following a traditional way and aged for many years in a set of barrels (transferring a certain amount of vinegar from one cask to another in a decreasing “topping up” procedure) is great, when compared to AB industrially prepared with caramel. AB PGI is certainly the most widespread industrial-type vinegar in the world, deriving from low-temperature condensed grape must (or cooked must) mixed with wine vinegar, obtaining balsamic vinegars with a caramel-like taste. Depending on its economic value, ABT PDO is often object of fraud, requiring to fight counterfeit products and imitations.

Unveiling the unknow aroma potential of Port wine fortification spirit taking advantage of the comprehensive two-dimensional gas chromatography

Port wine is a fortified wine exclusively produced in the Douro Appellation (Portugal) under very specific conditions resulting from natural and human factors. Its intrinsic aroma characteristics are modulated upon a network of factors, such as the terroir, varieties and winemaking procedures that include a wide set of steps, namely the fortification with grape spirit (ca. 77% v/v ethanol).
