The aim of this study is to explore the impact of cadmium (Cd) and arsenic (As) stress on physiological indexes and Cd/As uptake ability of Miscanthus, including Miscanthus sacchariflorus A0104, Miscanthus sinensis C0424 and C0640. Cd and As concentration showed significant hormesis effects on some physiological indexes, such as chlorophyll content, net photosynthetic rate, and MDA content. Compared with control group, Cd uptake can be most greatly enhanced by above fourfold with 150mg/kg Cd treatment. As uptake of A0104 was increased by 3 ~ 33...
