Mercury-tolerance ofChloris barbata Sw. andCyperus rotundus L. isolated from contaminated sites
- 1 Department of Botany, Berhampur University, Orissa, India
Chloris barbata Sw. andCyperus rotundus L. from a mercury contaminated site near a chloralkali plant were tested for relative tolerance to Hg by root-elongation method. The above two species from the Hg-contaminated site exhibited high tolerance to Hg compared to the same species from a non-contaminated site. Tolerance to Hg was higher inChloris barbata than inCyperus rotundus.
