Abstract

Cadmium (Cd) is absorbed easily by the root system of many plant species. Due to its solubility in water and toxicity is considered as a major pollutant. The aim of this study was to investigate the cadmium toxicity on some physiological characteristics of lentil seedlings. Two-week-old seedlings were treated with different concentrations (0 as control, 0.125, 0.25, 0.5, 1, 2.5 and 5 mM) of cadmium chloride in a completely randomized design with three replications for 10 days and then the amounts of PHOTOSYNTHETIC PIGMENTS, PROLINE, soluble proteins and activity of some ANTIOXIDANT ENZYMES (superoxide dismutase, catalase and ascorbate peroxidase) were investigated. Results indicated that with increase of cadmium concentration, significant reduction was observed in PHOTOSYNTHETIC PIGMENTS. Furthermore, the cadmium significantly increased the amount of PROLINE in treated seedlings compared with control. Also, cadmium has imposed drastic decrease in total soluble proteins and the amount of proteins declined progressively with increasing concentrations of cadmium. ANTIOXIDANT ENZYMES evaluation determination showed that with increasing concentrations of cadmium, the activity of ANTIOXIDANT ENZYMES such as superoxide dismutase, catalase and ascorbate peroxidase were increased in lentil seedlings. Due to the reduction of protein contents and PHOTOSYNTHETIC PIGMENTS, the present results allow us to conclude that the lentil plants adversely affected by cadmium toxicity. To overcome CADMIUM STRESS, seedlings have increased the activity of antioxidative enzymes as well as PROLINE.
