Abstract
Cd uptake,subcellular distribution and interaction between Cd and Ca in pakchio were studied.The results showed that Cd was mainly kept in the roots of two cultivars of pakchoi,and the concentration of Cd in shoot of cv.Hangzhouyoudong was higher than that of cv.Huqing No.1,but the concentration of Cd in root was the opposite.The Cd concentrations of subcellular fraction increased with increasing Cd concentration in the growth medium.Cd was accumulated mainly in cytoplasm of shoots and this accumulation was fairly independent of Cd concentration in nutrient solution.The lowest Cd concentration was found in organelles fractions of both Cd concentrations.There were differences between two cultivars which the distribution rate of cell wall fraction in cv.Hangzhouyoudong was higher than that of cv.Huqing No.1.Ca was mainly retained in the cytoplasm fraction.In cytoplasm and cell wall fractions,Cd and Ca had a synergistic effect at 0.1 mg/L Cd concentration,and had an antagonistic effect at 1.0 mg/L Cd concentration.
