Abstract

Soil contamination by cadmium (Cd) is the main problem in the industrialized and developing countries. Phytoremediation is a simple and inexpensive technique to reduce the environment contamination. The present study evaluates the potential of ornamental cabbage varieties in removal of Cd from contaminated soils. Treatments were cultivars at two levels (songbird red and songbird white) and Cd concentrations at four levels (0, 10, 20 and 30 mg/kg). The experiment was laid out as a factorial based on randomized complete block design using three replicates. Roots and shoots Cd content, anthocyanin, proline, chl.a, chl.b, chl.a + b contents were measured. Results showed that the amount of Cd in shoots and roots of both species was increased with the increasing Cd concentrations. Higher accumulation of cadmium in roots and shoot of white cabbage was detected in comparison with red cabbage. The amount of chlorophyll and proline in white cabbage were not affected by different concentrations of cadmium. Proline production was found to be higher in red cabbage compared to white cabbage under cadmium treatment. Thus, two cabbage species can be used for phytoremediation of Cd-contaminated soils. However, if these species are used as hyper-accumulate, they should be burn after harvesting like dangerous waste.
