ABSTRACT
No data are available on the content of heavy metals in the xylem sap of grapevines growing in contaminated areas. The aim of this work was to obtain data on the concentration of Pb, Zn, Cd and Cu in the xylem sap of grapevine (Vitis vinifera) cultivar Monica (ungrafted), growing near contaminated sites: a smelter, an abandoned and an active mine, and to investigate relationships between xylem sap mineral composition and the heavy metal content of the soil. The concentrations of Pb, Zn, Cd and Cu in the sap were enhanced compared to that of the soil, ranging from 4.3 to 611.4 micron Pb g-1d.wt., 801 to 6176 micron Zn g-1d.wt., 2.5 to 45 micron Cd g-1d.wt. and 19.8 to 161 micron Cu g-1d.wt.. Dry matter of xylem sap was significantly related to the heavy metals content in xylem saps, but no significant relationship between the metals in sap and total and DTPA/TEA extractable metal fraction in soil was found.
