We present in this work preliminary results on the translocation of copper, manganese and iron from soil to leaves of Sambucus nigra L. seedlings in the presence of increasing copper concentrations in the growth medium. The use of electron spin resonance spectroscopy and the comparison with atomic absorption spectroscopy is not presently common in the study of metal absorption in plants. This approach gave promising results both on the detection of some metal ions, as well as of radical species related to the presence of Cu2+ in plant tissues. Copper was found to act synergistically in manganese uptake.
在本研究中，我们展示了在生长培养基中铜浓度不断增加的情况下，黑接骨木幼苗中铜、锰和铁从土壤向叶片转运的初步结果。在植物金属吸收研究中，目前电子自旋共振光谱的使用以及与原子吸收光谱的比较并不常见。这种方法在检测一些金属离子以及与植物组织中Cu2+存在相关的自由基物种方面都取得了有前景的结果。研究发现，铜在锰的吸收过程中起协同作用。
