description: Phytoremediation of Cd‐contaminated soil using hyperaccumulators has become a new promising technique. Thunb. has been reported as a new Cd‐hyperaccumulator. In this study, the effect of Cd stress duration on growth, photosynthesis and mineral nutrition of was investigated. At 30 days after Cd stress, there was not any visual leaf symptoms in , and an obvious stimulating effect of 10 mg kg Cd on net photosynthesis rate (P) was well correlated to photosynthetic pigment contents and mineral nutrition (Mg and Fe) concentrations. With Cd stress time extended, no significant differences of shoots and total biomass and P compared with the control was observed, indicating that could develop effective tolerance mechanisms to avoid Cd‐induced damage to photosynthesis and growth. The photosynthetic performance remained functional through stomatal and non‐stomatal adjustments, and mineral nutrition responses. The improved growth based on shoots and total biomass and P by 10 mg kg Cd, as suggested by hormesis, may be beneficial to enhance the potential for phytoremediation, because it typically faced the low Cd concentrations in actual Cd‐contaminated soils. The study results indicated that could be used for phytoremediation contaminated soils by Cd. The results showed that has high tolerance to Cd stress. No significant differences of shoots and total biomass, Chl contents, P of compared with the control, could be observed, indicating that the plant could develop effective tolerance mechanisms to avoid Cd‐induced damage to photosynthesis and growth.
