Abstract

---

In this study toxicity and tolerance of Samanea saman (Jacq.) Merr. was investigated for Pb, Cd, Cu and Zn under lab conditions. Germination rate of S. saman showed that increased concentration of different metals from 25 to 100 ppm, significantly (pCu>Zn of sequence at different concentrations. Tolerance indices determined for different metal illustrated that increasing concentrations of metals reduced the tolerance of S. saman but this reduction was more prominent for Pb and Cd as compared to Cu and Zn treatments.
