Experimental treatments consisted of six levels of soil contamination to Cd (0, 10, 25, 50, and 100 mg Cd/kg soil from the cadmium sulfate [3Cd(SO4)×8H2O] source) and three varieties of cabbage (Brassica oleracea var. acephala L., Brassica oleracea var. italica L. & Brassica oleracea var. capitata L.) which were examined in triplicate. The Analysis of variance of data showed that the treatments had significant effects (P<0.01) on the fresh and dry weights of plant biomass, dry weights of root, stem and leaf, leaf surface and the leaf chlorophyll index of all the varieties of the cabbage. With the increase in the levels of soil Cd, the accumulation of Cd in the root, stem and leaf of the cabbage varieties significantly increased and the Cd concentration of the root was more than the aerial parts. So that in cabbage, broccoli and ornamental cabbage, at the highest level of soil Cd (100 mg/kg soil), the Cd concentration of root was respectively 28, 12 and 4 times greater than that of leaf. The highest Cd uptake was belonged to the cabbage (1.45 mg per plot) and the broccoli cabbage (0.79 mg per plot) and the ornamental cabbage (0.35 mg per plot) were in second and third places respectively. In all varieties of cabbage the highest Cd uptake was measured for the treatment with the highest level of soil cadmium (100 mg/kg soil) the lowest Cd uptake was observed in the control treatment. The translocation factor for all varieties of cabbage was less than one and the bioconcentration factor was more than one. The cabbage varieties were classified as cadmium excluder plants.
