Geochemistry of Vrbničko Polje (Croatia) winegrowing site

Abstract

A multi-element pedo-geochemical survey was carried out in Vrbničko polje vineyards on the Krk Island, Croatia. This Mediterranean winegrowing site is famous by Žlahtina wine production. The objectives of this study are (i) to describe characteristics of the site related to climate, topography, geology, soil and geochemistry and (ii) to integrate data on soil quality using GIS which can be applied with management information systems Two soil profiles were excavated and examined, and dominant soil type was determined, as well as physical and chemical characteristics of soil. Topsoil (0-30 cm) and subsoil (30-60 cm) samples were collected from 26 locations inside the site. Total metal contents (Al, Ca, Cd, Co, Cr, Cu, Fe, Mg, Mn, Mo, Ni, P, Pb, S, V, Zn) were determined using ICP-OES after aqua regia extraction. A geospatial database was compiled in GIS, and after applying statistics and geostatistisc, the maps of trace metals distribution have been produced. Accumulation of copper in soil, determined in this research, is the most common effect of continuing fertilization and protection against diseases and pests in vineyards. High nickel and chromium concentrations seem to be of the geogenic origin. Associations of heavy metals with the selected soil properties explain the preferential feature of metal retention in soil.

Corvina berry morphology and grape composition as affected by two training system (Pergola and Guyot) in a context of climate change scenario

The Valpolicella area (Veneto Region, Italy) is famous for its high quality wines: Amarone and Recioto, both obtained from partial post-harvest dehydrated red grapes. The main cultivars used for these wines are Corvina and Corvinone. In this Region hundreds of years ago a particular training system (Pergola, cordon/cane with horizontal shoot-positioning) was developed. In the last 20 years the Guyot have been introduced in the area; now Pergola and Guyot are equally widespread in the Valpolicella area. In two different environmental conditions (hill and floodplain) two vineyards, one for each type of training system, were studied along two years (2011-2012).

Influence of methyl jasmonate foliar application to vineyard on grape volatile composition over three consecutive vintages

An alternative to improve grape quality is the application to the vineyard of elicitors. Although these compounds were first used to increase resistance of plants against pathogens, it has been found that they are also able to induce mechanisms involved in the synthesis of phenolic compounds and some amino acids. However, researches about the influence of elicitors on grape volatile composition are scarcely. Therefore, the aim of this work was to study the influence of methyl jasmonate (MeJ) foliar application on grape aroma composition over three consecutive vintages. MeJ was applied to Tempranillo grapevines at a concentration of 10 mM in 2013, 2014, and 2015 years. Control plants were sprayed with water.
