ABSTRACT
The uptake and translocation of hexavalent chromium (Cr (VI)) by four ornamental plant species was
investigated. Aptenia cordofolia L., Brassica juncea L., Brassica oleracea L., and Alyssum maritima L.
species were planted in peat growth medium and exposed to Cr (VI) with irrigation water in a range of concentrations
from 0.05 to 1 mmol·l-1 for 10 weeks. The results found in this study indicated that the Cr (VI) concentrations
in irrigation water significantly affected the Cr uptake and translocation capacities and the growth
responses of all four plants. The increases in the concentration of the Cr (VI) in the irrigation water increased
the accumulation and translocation of Cr in the root and shoot of the plants. The Cr concentrations found in
the shoots of tested plants were relatively low in comparison with the plants classified as Cr-hyperaccumulators.
The Cr accumulation in the shoot of tested plants was recorded in the order of Alyssum maritima L. >
Aptenia cordofolia L. > Brassica oleracea L. > Brassica juncea L., for the root the order was Brassica juncea
L. > Brassica oleracea L. > Alyssum maritima L. > Aptenia cordofolia L.
