Özet

Pollution of the environment and soils by heavy metals is one of the major problems of our time. Our study was to determine the effect of five doses for : zinc, lead and cadmium (0, 2500, 5000, 7500, and 10000 ppm) applied to the Atriplex canescens after 60 days for two weeks. The results showed an increase in the total polyphenols and flavonoids, depending on the increasing concentration of heavy metals at the leaf and root levels. The leaves have total polyphenols and flavonoids higher than those of the roots. The highest levels of total polyphenols and flavonoids in the leaves (3.47 mg EAG/g dry weight of total polyphenols and 3.70 mg EQ/g dry weight of flavonoids) were obtained at a dose of 10000 ppm (cadmium, lead) respectively. On the other hand, the highest levels of total polyphenols and flavonoids in the roots were obtained at the metallic dose of 10000 ppm for cadmium (3.38 mg EAG/g dry weight of total polyphenols and 0.61 mg EQ/g dry weight of flavonoids). These results also underlined the important role of secondary metabolites (total polyphenols and flavonoids) in the defense against oxidative stress caused by metallic stress.
