Heavy metals are part of the most important and dangerous environmental pollutants due to their long shelf life, non-degradability by soil microorganisms, and high potential for absorption by plants and entering the food chain. Cadmium is one of the toxic metals for organisms such as plants. The purpose of this research was to investigate the effect of cadmium on the ability of the common daisy plant. In this research, the effect of different amounts of cadmium (0, 10, 20 and 30 mgl-1) had done in a completely randomized design with three replicates. The results showed that the increase of the cadmium hadn’t any significant effect on common daisy plant fresh weight and length. Also, plant dry weight, shoot total chlorophyll, shoot and root carotenoids contents, total protein contents, plant translocation factor and bioaccumulation factor decreased with the increase of cadmium concentration, significantly. While shoot and root proline, and cadmium contents and catalase, peroxidase and ascorbate peroxidase activity increased, significantly. According to this research, the common daisy isn’t suitable for planting in studied cadmium concentrations.
