摘要
用中子活化分析测定了油菜叶绿体中的稀土元素含量。结果表明叶绿体中含有微量稀土 ,其含量相当于每个稀土原子对应约 2 0 0 0个叶绿素分子 ,低于Fe ,Mn 。
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.
