Root sequestration and antioxidant defense underpin cadmium tolerance in Arundo donax under contrasting Cd concentrations.
Cadmium (Cd) contamination poses a persistent threat to plant growth and environmental safety, yet plant responses to contrasting Cd exposure remain insufficiently understood. Here, Arundo donax seedlings were hydroponically exposed to low (0.1 mM) and high (1.0 mM) Cd stress. Physiological responses were evaluated aft...
