In this research, the effect of etylendiamintetraacetic acid (EDTA) on chromium accumulation and growth of Raphanus sativus L. was studied. 10-day old seedlings were cultured in hydroponic conditions containing different concentrations of chromium (1, 2, 4 and 6 mg/L) and EDTA (1 and 3 mg/L) for 4 weeks. After harvesting, growth parameters, amount of chromium in shoot and root and also prolin in shoot were measured. The results of this study showed shoot and root length, leaf area and root area, root/shoot ratio significantly increased at 6 mg/lit cr by using of EDTA, compared to chromium alone. Measurement of prolin showed that the amount of prolin in shoot was significantly decreased compared to chromium, at 6 mg/lit cr and 1 and 3 mg/L EDTA. According to the results of this research, appropriate concentration of EDTA decreased stress of chromium, so that not only did not have any negative effect on plant growth it enhanced the growth of the plant.
