Red bean seed was treated with solution of different concentrations of copper and seed germination rate and seedling growth of red bean were determined to study effect of copper solution of different concentration（0.1, 0.3, 0.5, 1.0 g / L Cu²⁺） on red bean seed germination, seedling growth and physiological characteristics. The results showed that with the increase of the concentration of copper, seed germination rate, plant height and root length of red bean were inhibited.
