The rare earth elements are a set of seventeen chemical elements which involve the lanthanide series from Lanthanum (La), Tolutetium (Lu), Scandium (Sc), and Yttrium (Y) in the periodic table. Even if Rare Earth Elements are used widely in industry and agriculture in China as well as India for a long time, there has been increasing interest in the application of REEs to plants in recent years. In this paper, we discussed the effect of REE on growth and physiological activities of the plant. By compilation and investigation of these data, we found that REEs have promoting impact at certain concentration. An increase in Chlorophyll, enzymes and protein content further indicated the stimulating effect of La on physiological activities of the selected plants. Depending on the results of this preliminary investigation we can say that a new REE hyperaccumulator, Cymbopogon flexuosus (Lemon grass), was discovered which could accumulate Lanthanum is 20.725 mg g-1 and 25.625 mg g-1 dry mass in root and shoot part respectively under natural growth conditions. Advanced research should be invested regarding the impacts of REEs on yields of cultivated plants.
