The contamination of soils by heavy metals is often caused through human activities and phytoremediation, using plants to remove toxic metals from soil is effective and economical solution. This research was conducted to study the effect of chloride and potassium sulfate on cadmium uptake and its phytoremediation improvement by L. Brassica napus in vitro through The Mashhad Torogh research in crop year 1391-1392. This project was carried out in a randomized completely block sample with three replications. The experiment consists of 3 cadmium levels (0, 15, 30 mg/Kg cadmium) resulted from source of cadmium nitrate and 10 levels of potassium fertilizer treatments which includes a control level (without potassium fertilizer), potassium chloride including levels of 100, 200 and 300 mg/Kg obtained from potassium chloride source, potassium sulfate containing levels of 100, 200, 300 mg/Kg obtained from potassium sulfate source and mixture of chloride and potassium sulfate (100, 200, 300 mg/Kg obtained from sources mixture of potassium sulfate and chloride). Figure (Modena) of the autumn canola was planted for this purpose. The analysis of variance results showed that cadmium levels and different amounts of potassium fertilizers had a significant effect on the aerial organ and root dry weight and potassium concentration and soil properties such as pH and electrical conductivity. The highest cadmium uptake amount was resulted by consumption of 300 mg/Kg potassium chloride. Therefore, the canola plant is convenient for cadmium absorption plant in phytoremediation technology on basis of the laboratory analyses and pot test results and uptake of potassium chloride can also improve the phytoremediation efficiency of soil contaminated by cadmium.
