Heavy metals in soils cause human health and environmental risks, therefore remediation of heavy metal contaminated sites is an important issue. Marigolds have been proposed as potential plants for phytoremediation of this type of contamination. In our experiment a seed germination test was carried out to investigate the toxic effects of heavy metals (Cu, Zn and Pb) on early growth of three different marigold species (African marigold, French marigold and Signet marigold). According to our results all tested heavy metals had significant (p<0.05) toxic effects on seed germination and root/shoot elongation of the three plants. Signet marigold was the most sensitive plant to heavy metals, while African marigold and French marigold were able to tolerate low concentration of metals (below 400 mg l-1 ) without considerable decline in growth parameters. These results indicate that African marigold and French marigold could be suitable for remediating heavy metal (Cu, Zn and Pb) contaminated soils.
