Absorption and subcellular distribution of cadmium in tea plant (Camellia sinensis cv. "Shuchazao").

A hydroponic experiment was performed to investigate the Cd absorption and subcellular distribution in tea plant, Camellia sinensis. Increased Cd accumulation potential was observed in the tea plant in a Cd-enriched environment, but most of the Cd was absorbed by the roots of C. sinensis.

Effects of cadmium on bioaccumulation and biochemical stress response in rice (Oryza sativa L.).

This study investigated the effects of various Cd concentrations on the bioaccumulation, antioxidative defense, and stress responses of rice (Oryza sativa L.). The distribution characteristics of Cd in rice were in the following order: roots>stems>grains.
