چکیده

the use of plants to remediate contaminated soil has been the most rapidly developing component in environmental cleansing. although total concentration of heavy metals in soil is used for regulatory review, it also is beneficial to assess the potential for ecosystem impact through a series of bioassays. one commonly used bioassay is seed germination. in current research study effect of contaminated soil with heavy metals (pb, zn, cu, fe) on germination and growth of puccinellia distans were evaluated. shoot and root concentrations of metals were also measured. data obtained from the experiment indicated that the plant perform dose-dependent responses to the contaminated soils. reduction in germination, root and shoot height and biomass were significantly (p

Germination, Growth and Uptake of Heavy Metals in Contaminated Soils (Hordeum bulbosum L.)

The use of metal-accumulating plants to clean the contaminated soil with toxic metals is the most rapidly developing component of phytoremediation as an environmentally friendly technology. Overcoming harsh soil conditions and accelerating the recovery of degraded soils remain a worldwide restoration challenge. This study evaluated the effect of different concentrations of Pb, Zn, Cu and Fe on ...
