Cadmium is one of the main toxic pollutants and constitutes an important threat to human health. In other to study the effect of Cd stress on traits in garden cress and radish, an experiment was conducted based on completely randomized design in aeroponic system. In this study CdCl2 was used in three levels (control, 3 and 6 mg l-1). Seeds were cultivated in aeroponic system and Hogland nutrient solutions (with and without Cd) were used for irrigation. After 40 days morphological traits and cadmium accumulation were measured. The result in garden cress showed that control has produced the highest of plant height (32.67 cm), leaf number (30.83), root length (14.5 cm), dry weight of root (0.34 g) and shoot (1.52 g), fresh weight of root (2.27 g) and shoot (11.3 g) and the 6 mg l-1 produced the highest of cadmium accumulation in root and shoot (2.88 and 0.11 kg/g, respectively). Also the result in radish showed that the control has produced the highest of plant height (50.1 cm), leaf number (18.8), root length (26.7 cm), dry weight of root (0.41 g) and shoot (2.04 g), fresh weight of root (3.9 g) and shoot (27.01 g) and the 6 mg l-1 produced the highest of cadmium accumulation in root and shoot (2.88 and 0.11 kg/g, respectively). In total, Cd stress reduced measured traits mean in garden cress and radish.
