Heavy metal redistribution is relevant for the quality of edible crops and the suitability of hyperaccumulators for bioremediation. Root-to-shoot transfer via the xylem and redistribution in the aerial parts via the phloem differ between various heavy metals. In general, cadmium is more slowly released to the shoot than zinc (e.g., in wheat, bean, and lupin). However, rapid cadmium transport to the shoot was detected in the hyperaccumulator Solanum nigrum L. This is a key aspect in this article and might be important for bioremediation. The radionuclides 109 Cd and 65 Zn were used to investigate the respective influence of elevated cadmium or zinc in the root medium on the dynamics of the two heavy metals in S  .  nigrum . Although transport via the xylem to the leaves was similar for 109 Cd and 65 Zn, the further redistribution from older leaves to younger leaves, flowers, and fruits via the phloem was far less efficient for 109 Cd than for 65 Zn. Furthermore, the redistribution of 109 Cd within the shoot was negatively influenced by increased cadmium (but not by increased zinc) concentrations in the nutrient medium. The redistribution of 65 Zn in the shoot was selectively decreased by increased zinc concentrations (but generally not by cadmium).
