title: Potatoes - A crop resistant against input of heavy metals from the metallicaly contaminated soil.
abstract: The objective of our study was to assess the extent of accumulation of cadmium, lead and zinc in potato tubers depending on the concentration of these heavy metals in soil and to evaluate the resistance of 11 cultivars of potato cultivated in 5 localities of the Slovakia against input of these heavy metals into the consumption part of potato. Contents of Cd (Pb, Zn) in soil were 0.94-2.54 (18.03-24.90, 35.71-72.40) mg/kg in soil extract by aqua regia and 0.030-0.188 (0.149-0.356, 0.052-0.238) mg/kg in soil extract by NH4NO3. The contents of Cd, Pb, and Zn were determined in potatoes in extracts of freeze-dried samples and expressed in mg/kg of fresh matter (FM). Determined contents of heavy metals were in the range of ND-0.058 mg Cd/kg FM, 0.020-0.630 mg Pb/kg FM, 1.836-3.457 mg Zn/kg FM, resp. The statistically significant correlation between heavy metal content in soil and its content in potato tubers were confirmed only: cv. Laura - Spissky Stvrtok (Cd), cv. Red Anna - Odorin (Pb) and Marabel, Red Anna - Odorin, cv. Marabel - Belusa, cv. Volumia - Imel (Zn).
