ABSTRACT
This chapter discusses the study of hydroponic techniques to culture rice at seedling stage to investigate the root morphology and cell wall components in rice as affected by the interaction of selenium (Se) and cadmium (Cd). Se reduced the proportion of fine roots and increased the proportion of medium roots in rice. This effect was more pronounced with an increase in Se concentration. Se changed the root morphology of rice, suggesting that these changes can affects the uptake of Cd by rice. The content of Cd in roots increased significantly with an increase in the concentration. The results of the study support the hypothesis that Se changes the root morphology to inhibit Cd uptake and simultaneously changes the subcellular distribution of root Cd content to inhibit the transfer of Cd to aboveground parts of rice.
