- Combined Effects of Cadmium, Lead and Copper on the Growth and on Metal Uptake of Broad Beans, Carrots, Radishes and Marrow Vegetables

Toxic symptoms of plants treated with a metal ion may not always be due to the increase of the uptake of this metal by plant but might be the result of the effect of the addition of this metal on the uptake of the other metal ions by plant. Thus, the study of the effects of combined treatments with more than one metal is important. In the present study, we have studied using root-treatment and foliar-treatment the combined effect of lead, cadmium and copper on the growth of broad beans, radishes, carrots and marrow vegetables. The effect of presence of each metal ion on the uptake of the other metal ions on the various parts of the plants by both root-treatment and foliartreatment of plants have also been studied. The results have shown that the combined effect of metal ions differs from one case to another with variation of the metal ions, piant, part of piant or type of treatment.
