Abstract
This study aims to investigate the ability of cadmium (Cd) accumulation in Peristrophe bivalvis cultivated in a pot experiment for 60 days at various Cd amounts of 0, 20, 60, and 100mg/kg. Throughout the experiment, no toxic effects were observed, and the presence of Cd did not inhibit the growth of the plants. A linear correlation coefficient (P < 0.05) showed that there was a significant decrease in leaf stomata opening due to Cd stress. After treatment with a high concentration of Cd in the root rather than the shoot (P < 0.05), the plant's Cd accumulation increased significantly. P. bivalvis demonstrated reduced translocation factor (TF) and bioconcentration factor (BAF) values < 1; nevertheless, by the end of the experiment, the enhanced Cd uptake value on concentration showed the maximum value of 1.56mg/plant. The results suggest that P. bivalvis had a tolerance and phytostabilization ability for Cd.
