Abstract

Specific plants can remove heavy metals from the soil and contribute to pollution remediation in croppingsystems. Determining the level of highest heavy metals that a super-accumulator crop can withstand withoutreducing its yield is important for management. The objective of this study was to investigate the heavymetal-removing capacity of purslane by studying different stress criteria and by tracking its nickel andcadmium removal from germination to harvest. Therefore, pot experiments in outdoor condition wereperformed by heavy metal levels including nickel (0, 30, 60, 120 mg/kg) and cadmium (0, 10, 20, 40 mg/kg)in two seasons. The results of this research showed that different levels of nickel and cadmium had significanteffects on the morphological and physiological characteristics of purslane and increased heavy metalsconcentration decreased significantly these characteristics. Comparisons of mean shoot and root dry weightand extraction percentage showed that the highest level belonged to the control plants while the lowest levelwas observed in the plants under combined treatment of nickel (120 mg/kg) and cadmium (40 mg/kg) andthe single treatment of cadmium (40 mg/kg). Perhaps heavy metals by their effect on dry and fresh mattermade negative influence on extraction. Furthermore, the toxic properties of cadmium were more than nickeland decreased most of the measured characteristics.
