Abstract: Objective: comparing the different methods of enriching gemanium(Ge) to barley seedling and assaying the Ge content in the enriched barley seedlings and touning the poisonous inorganic Ge to no poisonous organic Ge through barley seedling biotransformation in order to get a new kind of health food for man and a new way to decontaminate and protect entironment. Methods: Water culture barley seedlings; Enriching Ge barley seedlings by soaking seeds, after sprouting and in the whole process; The Ge in enriched barley seedling was examined by atomic fluorescence spectrometry. Result: The strong seedling concentrations are below 80 mg/L when adding Ge by soaking seeds and 40 mg/L when adding Ge after sprouting while all those barley seedlings no turning yellow and withered. The barley seedlings with adding Ge in the whole process grow slowly. Conclusion: The barley seedlings will grow well and the Ge content can reach high level with adding 40 mg/L concentration of Ge after sprouting and the total Ge content of the barley seedling is about 9.7 times of control. That is the best method and best concentration of Ge in this test.

Key words: enriched germanium barley seedling, Ge content, atomic fluorescence spectrometry
