摘要：

In the present study, bioaccumulation of REEs in Zea mays L. (corn plant) has been analyzed. The role of Rare Earth Element (REEs) in physiology and biochemistry of corn plant have been studied. Physiological characters like peroxidase (POD) and superoxide dismutase (SOD) activities, biochemical analysis of chlorophyll, carotenoids and phenol contents have also been carried out. The plant growth and biomass observed shows the influence of REEs and the accumulation studies reveal the presence of REEs only in roots. It was also found that REEs could increase POD and SOD activities, biochemical content and had an impact on crop production and stress resistance in plants.
