Abstract:
Phytotoxic effects of Cooper and Cadmium have been studied on germination of seeds and the content of chlorophyll pigments.The experiment was completed in accordance with OECD Protocol 208 (Guidelines for the Testing of Chemicals) and four concentration levels for Cu were used (16, 80, 200, 400 mg�kg soil) in the chemical form of CuSO4 and four concentration levels for Cd (0.8, 2.4, 4, 8 mg�kg soil) standard solution for atomic absorbtion standard solution (AAS), Both Cu and Cd have been embedded in the soil.The results show that the effect of inhibiting seed germination of bell pepper is higher in soil contaminated with Cd compared to soils contaminated with Cu. Chlorophyll pigments were extracted from fresh green leaves in an alcoholic extract and quantified using Lichtenthaler�s equations (1987), however, the determination of chlorophyll pigments (chlorophyll a, b, carotenes) from bell pepper leaves shows a rather large increase in the coefficients of variation. Therefore, we can conclude that the toxic compounds (Cu and Cd) induce structural and functional changes in the bell pepper photosynthesis mechanism.
