Abstract

We investigated the ability of triticale uptake of Mercury (Hg), clarified whether triticale root uptake of Hg2+ via Zinc (Zn2+) transports, using hydroponic experiments. At 25℃, when Hg exposure in solution was lower than 20 μM, Hg concentration in the roots can be better described by a hyperbolic function, which shows a saturable characteristic. Under ice-cold (< 2℃) conditions, a nonsaturable (linear) component was found. Low exposure of Zn2+ (0–1 μM) inhibited plant Hg uptake when Hg exposure in the solution ranged from 1 to 10 μM, it showed an antagonistic effect of Zn on plant uptake of Hg. When Hg exposure was 20 μM, it revealed a synergistic effect of Zn on plant uptake of Hg, Hg in the root increased at the Zn (1 μM) exposure in the solution. Our results will deepen the understanding of Hg transfer in the soil–plant system.
