Abstract:
The grapevine belongs to the family Vitaceae and is a widely cultivated plant throughout the world where approximately 80% of its grapes are used for wine production and a 13% are consumed as table grapes becoming one of the most popular fruits.
The quality characteristics of wines are influenced by environmental and anthropogenic factors and can be identified by varying contents of macro- and microelements and trace elements forming its chemical composition.
The aim of this thesis is to better understand the fluxes of macro- and microelements and trace elements in the system soil-plant, focusing on ten elements (Al, Cr, Fe, Ni, Cu , Zn, As, Cd, Sn, Pb).
The system soil-plant has been studied by analysing different matrices (soil, rasps, leaves, flowers and grapes) of three different cultivars (Glera, Garganega e Cabernet-sauvignon) in two vineyards of Veneto located in Visnà di Vazzola (TV) and Cologna Veneta (VR).
The quantification of these elements could be helpful to identify the distribution of the analytes in the soil and in the plant contributing to keep safe this natural resource emblem of the Mediterranean culture.
