چکیده انگلیسی
A pot-culture experiment was conducted to assess the effects of selenium (Se) (0.5â¯mgâ¯kg-1) on Trifolium repens exposed to various levels of diesel (0, 15, 20, 25â¯gâ¯kg-1) for 30 days and 60 days. Exposure to diesel for 60â¯day led to concentration-dependent decreases in root morphogenesis, chlorophyll content and CAT activity, and to dose-dependent increases in MDA content and SOD activity. The residual diesel concentration in soil increased and the removal efficiency decreased with soil diesel concentration. The chlorophyll content and residual diesel concentration after were slightly higher at 30 days than at 60days. Application of Se to soil increased Trifolium repens tolerance to diesel and significantly increased the phytoremediation effect at 60 days, with a removal rate of 36â¯Â±â¯8%, compared to 28â¯Â±â¯7% in the control. These results contribute to the ongoing effort to develop an effective phytoremediation system for soils highly contaminated by diesel.
