摘要
用火焰原子吸收法测定绿豆萌发过程中铜、铁、锰和锌的含量，研究不同含量碘离子胁迫对绿豆萌发过程中生理活动的影响。结果显示，各含量培养液所培养的绿豆芽苗中4种元素含量随培养时间的增加而显著降低，适当质量浓度的碘离子（20～80mg／L）可以促进绿豆对铜、铁、锌的溶出，但碘离子质量浓度过高（〉100mg／L）时将抑制绿豆对铜、铁、锰的溶渗出，培养末期绿豆均能从培养液中重新利用铁、锰、锌3种微量元素。
Studying different concentration of iodine stress on germination and sprouting of mung bean by determining the content of Fe in the process of germination of mung bean mung bean during germination. The result showed that the contents of the four trace elements decreased with extended of incubation time. The dissolution ratios of Cu,Fe and Zn were promoted by appropriate concentration of iodide(20~80 mg/L),and the leakage ratios of Cu,Fe and Mn were inhibited by excessive100 mg/L iodide solution, and mung bean can recycle three kinds of trace elements Fe,Mn,Zn from the culture medium in the late of culture.
