摘要
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。
The effect of selenium applied at different levels on the growth of barely and accumulation of selenium was studied. The results were as follows: ① The barely possessed a great ability in selenium biological accumulation, and the contents of total selenium in treated barely were 10 μg·g-1, 60 times more than that of the control, and 90% of total selenium existed in organic matters as protein, nucleic acids and polysaccharides; ② Selenium increased the contents of protein and inhibited the respiratory intensity of barely, and the optimum concentration for increasing the contents of nucleic acids was 10 mg·L-1; ③ Selenium had antioxidation and increased the activity of peroxidase, polyphenoloxidase and glutathione peroxidase in malt.
