The presence of certain elements in the soil controls their bioavailability to the plant. Uptake
of elements depends on their concentration, solubility of occurring form and soil properties. Also,
the propensity of the plant for the bioaccumulation process will condition the transfer of ions of
elements from the soil to the various parts of the plant. Sometimes good bioaccumulation properties
of plants can be used for their application for bioremediation of polluted areas.
The objective of the present study was to determine the concentrations of selected elements
in the rhizome and above-ground parts of Iris pumila grown in Deliblato Sands (Serbia) in relation
to its surrounding soil. Potassium and selenium contents (mg kg-1of dry matter) were determined
by ICP-OES method after digestion of samples. The concentration, transfer and accumulation of
some elements from the soil to rhizome and above-ground parts were evaluated in terms of Biological
Absorption Coefficient (BAC): cplant part/csoil. The concentration of K+ ions in soil, rhizome,
above-ground vegetative parts and flower were: 1,845.3 mg kg-1, 1,307.0 mg kg-1, 4,461.4 mg kg-1
and 2,875.1 mg kg-1, respectively. The presence of selenium as a trace element was confirmed both
in the soil (0.112 mg kg-1) and in the plant parts (rhizome - 0.156 mg kg-1; above-ground vegetative parts- 0.135 mg kg-1; flower - 0.122 mg kg-1). The obtained results confirmed that the aboveground
parts accumulated potassium (BACvegetative= 2.42; BACflowers= 1.56). Also, all plant parts have
shown the ability to bond selenium from soil in significant quantities (BACrhizomes= 1.38; BACvegetative= 1.20; BACflowers= 1.08). This suggests that this specie have potential in phytoremediation.
