Abstract. Plants show a different ability in the uptake and accumulation of heavy metals. A differentiated ability of heavy metal accumulation occurs between species and cultivars. Among the radish cultivars grown in autumn, ‘Opolanka’ and ‘Rowa’ were characterized by the least content of cadmium and lead. In the spring cultivation, ‘Rowa’ cv. contained the least amount of cadmium, while ‘Rowa’ and ‘Krasa’ showed the least amount of lead.
Key words:
cadmium, lead, cultivars, radish
Differences in cadmium and lead accumulation by radish depending on the cultivar
Summary
Pot experiments with radish were carried out in autumn in the years 1998-2000 (‘Opolanka’, ‘Rowa’, ‘Saxa’, ‘Silesia’ and ‘Warta’ cultivars) and in spring 1999-2000 (‘Krakowianka’, ‘Krasa’, ‘Mila’, ‘Rowa’ and ‘Saxa’ cv.). Cadmium was applied in the doses: 0; 2; 5; 10 and 25 mg Cd ∙ dm-3; lead was used in the doses: 0; 10; 50; 100; 150; mg Pb ∙ dm-3. Cadmium and lead were applide together. Two radish cultivars grown in autumn (‘Opolanka’ and ‘Rowa’) were characterized by the least content of cadmium and lead. In the spring cultivation, the ‘Rowa’ cv. showed the least content of cadmium and ‘Rowa’ and ‘Krasa’ had the least content of lead. The radish cultivars grown in autumn accumulated less cadmium and lead than those grown in spring.
