Abstract This study aimed to determine the effects of different Cd concentrations (0, 1, 10, 100, and 300 μM CdCl2) on Allium plantlets. To achieve this goal, we examined the (1) dynamics of Cd2+ flux in the rhizosphere, (2) partitioning of Cd between roots and leaves, (3) formation of reactive oxygen species (ROS), (4) levels of H2O2 and chlorophyll, and (5) translocation of several macro- and micronutrients. A strong net Cd2+ influx was observed in the root apex after exposure to 100 μM Cd for 24 h. Exposure to either 1 or 10 μM Cd for 96 h presented no evident… More >
