Koelreuteria paniculata were cultivated in nutrient solution with different concentrations of Cd (0, 50, 150, 250 and 500microM) and sampled after 90 days. The resistance, translocation, accumulation and stress responses in Koelreuteria paniculata were investigated by hydroponic experiments. The results showed that Koelreuteria paniculata is an efficient Cd excluder that can tolerate high concentrations of Cd (up to 150-250microM of Cd). The concentration of Cd never exceeds 5ppm in leaves and 10ppm in roots. The high concentration of Cd (>/= 250microM) had a toxic effect on K. paniculata and ...
