Radish (Raphanus sativus L.) plants were grown with 0, 100 and 150 mg/kg soil cadmium chloride and treated with 100 or 200 mg/l chitosan or humic acid as soil additives to study the responses of leaf area, metabolite accumulation, oxidative stress and enzymatic and non-enzymatic antioxidant physiological processes to cadmium or chelators and to show the influence of chelating application on the alleviation of cadmium chloride induced adverse effects. Results revealed that cadmium stress caused reduction in leaf area, parallel to increased hydrogen peroxide levels, lipid peroxidation and electrolyte leakage in shoot tissues which were significantly reversed by either humic acid or chitosan. The antioxygenic enzymes viz. catalase and peroxidase were significantly decreased due to increasing cadmium concentration.
