| Abstract: | The contents of 8 rare earth elements(REEs)in chloroplasts of Brassia napus were determined by instrumental neutron activation analysis.The results indicated that there were trace amounts of REEs in the chloroplasts,which corresponded to 1 atom of REEs per 2000 chlorophyll molecules.This content was lower than the microelements already known essential for the process of photosynthesis such as Fe,Mn and Cu. |
