Abstract

Cadmium is one of the most dangerous Heavy metals that enter to soil naturally or by human activity and causes oxidative stress in plants. Therefore, this study was conducted to evaluate the effect of cadmium on some of the physiological responses of three Aromatic plants including Mentha aquatica L., Eryngium caucasicum Trautv. and Froriepia subpinnata Ledeb. In three greenhouse experiments, five concentrations of cadmium containing 0, 5, 10, 15 and 20 mg/kg soil was investigate in a completely randomized design with four replications at Sari Agricultural Sciences and Natural Resources University, in 2017. All three plants seedlings were transplanted in cadmium contaminated pots. In before flowering stage chlorophyll a, b, carotenoid, Phenol, Flavonoid and Antioxidant capacity of shoots were measured. Chlorophyll a, b and carotenoid content were measured by using leaf methanolic extract. Total Phenol, total Flavonoid and Antioxidant activity of shoots hydroethanolic extract, were respectively performed using the Folin-Ciocalteu reagent, AlCl3 method and DPPH. The results were showed that leaf pigment in all three plants decreased linearly with increasing cadmium level, but the rate of carotenoid reduction was lower than chlorophyll a and b reduction. While Flavonoid, Phenol and Antioxidant capacity of plants increased with increasing cadmium level. M. aquatica had the average highest Phenol (65. 89 mg/g) and Antioxidant activity (98. 49%) than other two plants. F. subpinnata had the average highest Flavonoid (165. 06 mg/g). Finally, the results showed that plant pigments were affected by cadmium toxicity, and since these plants are rich in Antioxidant compounds, the increase of these compounds with increment of cadmium stress is a kind of defence mechanism of three plants for conflict with stress.
