以麦芽为富硒载体,研究不同供硒水平对麦芽生长的影响及大麦对硒的富集作用。结果表明:①麦芽对硒有很强的富集能力,麦芽体内的含硒量可达10μg·g-1,比对照增加60多倍,其中90%以上以有机物如蛋白质、核酸、多糖等化合物存在;②硒对麦芽的呼吸强度有抑制作用,低浓度可促进麦芽中蛋白质、核酸合成;③低浓度硒可提高麦芽体内过氧化物酶、多酚氧化酶及谷胱甘肽过氧化物还原酶的活性。 Malt as selenium carrier to study the different levels of selenium on malt growth and barley enrichment of selenium. The results showed that: ① Malt had a strong ability to enrich selenium, the content of selenium in malt was up to 10μg · g-1, more than 60 times higher than that of the control, of which more than 90% contained organic compounds such as protein, nucleic acid and polysaccharide ; ② Selenium inhibited the respiration of malt, low concentration could promote malt protein and nucleic acid synthesis; ③ Low concentration selenium could increase peroxidase, polyphenol oxidase and glutathione peroxidase Enzyme activity.
