大麦苗富锗的研究

Production of Enriched Germanium Barley Seedling

目的:探讨大麦苗不同富集锗的方法以及不同浓度的锗对大麦苗的生长及富锗量的影响,为开发富锗大麦苗保健品以及探索一条通过大麦苗的生物转化作用将环境中的有毒的无机锗转化为无毒的有机锗为人类服务同时又净化保护了环境的新途径。方法:水培法栽培大麦苗;浸麦富锗法,出苗后富锗法以及全程富锗法;原子分光光谱法测定富锗麦苗中锗的含量。结果:浸麦富锗法中锗浓度低于80mg/L组和出苗后富锗法中锗浓度为40mg/L组的麦苗生长曲线均高于空白对照组,且无麦苗尖发枯发黄现象。全程富锗法,各富锗组麦苗的出芽率、麦苗出率、生长曲线大部分低于空白对照组,且麦苗尖发枯发黄。结论:出苗后富锗法,当锗浓度为40mg/L时,大麦出芽率、麦苗出率、生长曲线均高于空白对照组,麦苗尖无发枯发黄,锗含量高是空白对照组的9.7倍,此为本实验中最佳富锗方法与最佳富锗浓度。

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.
