Abstract: Cadmium is one of the most important toxicity elements and it can transfer easily in soil and from soil to plant. Calcium is one of the essential elements for plant growth and it plays an important role in plant growth and signal transduction.[Objective][Method] In order to understand more clearly the ecological effects of cadmium-calcium interactions on plants, explore the interaction mechanism of Cd and Ca coexistence and make the best of the relationship between the Cd and Ca, it is possible to provide scientific foundation for preventing and controlling heavy metals contamination.[Result]This paper reviewed the ecological effects of cadmium-calcium interactions on plants, including: (1) In the process of plant uptake, cadmium and calcium were antagonistic relationship. On the one hand, Cd could inhibit the absorption of Ca by plants to limit the growth of plants; On the other hand, Ca could inhibit the absorption of Cd by plants to relieve cadmium toxicity. (2)The application of exogenous Ca could promote the growth of photosynthetic pigments and the synthesis of photosynthetic pigments under Cd toxicity. (3) In the process of regulating the activities of antioxidant enzymes, the application of exogenous Ca could enhance antioxidant enzyme activities to reduce oxidative damage. [Conclusion]Thus, the effects of cadmium and calcium on plant growth, photosynthetic pigments and antioxidant enzyme activities were antagonistic.
