Abstract: Pollution by heavy metals in the environment
is a worldwide problem. The aim of the research study was to record
the effect of lead (Pb) and iron (Fe) elements on early seedling
growth of Albizia lebbeck L. (Benth.) and Eucalyptus
globulus Labill. The obtained results showed that higher
level of lead (Pb) and iron (Fe) elements treatment present in
the substrate had wide a spectrum of toxicity activity against
seedlings growth performance of A. lebbeck and E.
globulus as compared to control in lab conditions. Statistically
analyzed data showed that seedling growth of A. lebbeck
and E. globulus were reduced significantly (p<0.05)
with increased concentrations of Pb and Fe 5 to 20 ppm as compared
control (0 ppm). The percentage of seedling tolerance index of
A. lebbeck and E. globulus showed different
level of iron and lead. A. lebbeck showed greater tolerance
indices (61.19%) in the presence of Fe than Pb treatments (50.39%).
It was also noted that tolerance indices of E. globulus
was reduced more in Fe (41.19%) as compared to Pb treatments (55.32%).
