Influence of cultivar on the content of selected minerals in red beet roots (Beta vulgaris L.)
Nizioł-Łukaszewska, Zofia | Gawęda, Maria
Beetroot is a vegetable that accumulate heavy metals. This is largely dependent on the cultivar, methods and growing conditions. The aim of the study was to determine the composition of elements in the roots of 15 cultivars of red beet. The analysis assessed the content of macroelements (Na, P) and heavy metals (Cd, Cr, Mn, Zn). Most soils of the Lesser Poland region are exposed to the impact of industrial and transportation pollution. The soils of this region are characterized by strong acidification as well as natural or increased heavy metal content. The experiment was set up at the experimental field of the Department of Vegetable and Medicinal Plants of the University of Agriculture in Krakow, in 2009-2010. On the basis of the performed analysis, ‘Opolski’ was chosen as the cultivar that was characterized by a high content of macroelements and lower ability to accumulate heavy metals than the other tested cultivars. The lowest ability to accumulate heavy metals (Cd and Cr) was found in the cases of cultivars with cylindrical root shapes, such as Rywal or Opolski. One can indicate such cultivars as Astar F₁ or Nabab F₁ as cultivars recommended for cultivation in ecologically threatened areas.
