Lead uptake by roots of four turfgrass species in hydroponic cultures
HortScience, 38(4), 623–626.
Reed plants (Pharagmites australis) may reduce heavy metals pollution of water used for irrigation of crop plants by phytoremediation.However, the accumulation of high shoot concentrations of heavy metals might increase their distribution and may harm grazing animals.The aim of this study was to investigate the characteristics of root and shoot accumulation of lead as well as its accumulation level that occur in reed plant (Pharagmites australis) that naturally grow with wetlands in the Kingdom of Saudi Arabia using a hydroponic experiment.Shoot and root parts of Pharagmites australis were sampled and analyzed for lead (Pb).Differences in uptake and translocation characteristics of the plant samples were observed between naturally-grown reed plants and plants grown in the hydroponic experiment.These differences were explained by the differences in soil x root interactions.Reed plants were found to have restricted translocation of Pb to the shoot system and the highest concentration of the element was found in the root system.In conclusion, the results of this study indicated that the results hydroponic experimental studies must be confirmed by field studies in order to find suitable plant species for phytoremediation of polluted waters.In any case, reed plants represent a safe method to reduce Pb contamination.
