Heavy metal stress is a major abiotic stress factor that limit crop growth and development. The effects of heavy metals on plants resulted in structural damage, decline in physiological and biochemical activities, nutrient absorption as well as the growth of plants. Cadmium (Cd) is a widespread non-essential metal released into the environment through effluent from industries, mining and leakage of waste, and by fertilization with phosphate and sewage sludge and is readily taken up by plants. Many physicochemical methods have been proposed for heavy metals removal from water and soils. Among these, adsorption process through biochar has been found as one of the most promising technologies in pollution control. This experiment was done to study the effect of Cd on physiological properties and antioxidant system of strawberry and to evaluate the feasibility of pomegranate peel waste for the removal of Cd. The experiment was set up according to a complete randomized design with 4 replications and tests in ?Gavieta? cultivar. The changeable factors include Cd (0, 5 and 10 mg kg -1 ) and biochar level (0, 5 and 10 g kg -1 ). Changes in the chlorophyll and carotenoids and levels of several important parameters associated with oxidative stress, namely malondialdehyde (MDA), hydrogen peroxide (H 2 O 2 ), and electrolyte leakage (EL), and the activities of antioxidative enzymes (ascorbate peroxidase (APX), catalase (CAT)), as well as potassium (K), calcium (Ca), magnesium (Mg), iron (Fe) and zinc (Zn) contents in roots were measured. The results showed that exposure of the plants to Cd caused a gradual increase in EL and H 2 O 2 and MDA content. Cd treatment caused an increase of 15.94% and 73.11% in CAT and APX activity upon exposure to 10 mg kg -1 sand Cd, respectively. Addition of biochar significantly decreased the EL and level of shoot Cd and H 2 O 2 as well as CAT activity. It was concluded that addition of biochar had significant residual effect on reducing Cd uptake in strawberry under Cd stress. Phytotoxic effects of Cd on photosynthesis pigments was not significant. Addition of biochar decreased carotenoid content and increased chlorophyll content and chlorophyll a/b ratio in strawberry plants exposed to Cd. Cd and K show antagonistic interactions while relation between Cd and Ca, Mg, Fe and Zn was positive. Biochar addition significantly influenced K, Ca and Fe absorptions in the root. The overall results suggest that biochar application alleviate Cd stress by improving soil physical conditions, increasing some essential element and decreasing Cd absorption. Therefore, it may be concluded that under Cd stress condition, biochar application will be beneficial to diminish the risk of oxidative stress in strawberry plants.
