| 英文摘要 | Field survey, hydroponic culture, and pot experiments were carried out to examine and characterize cadmium (Cd) and zinc (Zn) uptake and accumulation by Sedum jinianum, a plant species native to China. Shoot Cd and Zn concentrations in S. jinianum growing on a lead/Zn mine area reached 103-478 and 4165-8349 mg kg(-1) (DM), respectively. The shoot Cd concentration increased with the increasing Cd supply, peaking at 5083 mg kg(-1) (DM) when grown in nutrient at a concentration of 100 mu mol L(-1) for 32 d, and decreased as the solution concentration increased from 200 to 400 mu mol L(-1). The shoot-to-root ratio of plant Cd concentrations was > 1 when grown in solution Cd concentrations <= 200 mu mol L(-1). Foliar, stem, and root Zn concentrations increased linearly with the increasing Zn level from 1 to 9600 mu mol L(-1). The Zn concentrations in various plant parts decreased in the order roots > stem > leaves, with maximum concentrations of 19.3, 33.8, and 46.1 g kg(-1) (DM), respectively, when plants were grown at 9600 mu mol Zn L(-1) for 32 d. Shoot Cd concentrations reached 16.4 and 79.8 mg kg(-1) (DM) when plants were grown in the pots of soil with Cd levels of 2.4mg kg(-1) and 9.2 mg kg(-1), respectively. At soil Zn levels of 619 and 4082 mg kg(-1), shoot Zn concentrations reached 1560 and 15,558 mg kg-1 (DM), respectively. The results indicate that S. jinianum is a Cd hyperaccumulator with a high capacity to accumulate Zn in the shoots. |
