摘要: 目的:探讨大麦苗不同富集硒的方法以及不同浓度的亚硒酸钠对大麦苗的生长及富硒量的影响。方法:采用水培法栽培大麦苗;富集硒的方法分别为浸麦富硒法、出苗后富硒法以及全程富硒法;透析袋法分离有机与无机硒;原子荧光光谱法测定富硒大麦苗中的硒含量。结果:浸麦富硒时,当亚硒酸钠浓度低于50mg/L时大麦苗生长旺盛,麦苗出率与生长曲线均高于空白对照组;出苗后富硒,亚硒酸钠为30mg/L时,其生长曲线高于空白对照组,其富硒量最高;全程富硒时,大麦苗出芽率,麦苗出率低,且生长迟缓。结论:出苗后富硒,当亚硒酸钠浓度为30mg/L时,大麦苗生长快,且富硒量最高,全硒含量是空白对照组的4.97倍,有机硒含量是空白对照的8.05倍。此为本实验中最佳富硒方法与最佳富硒浓度。

Abstract: Objective:Comparing the different ways of enriching selenium(Se) for barley seedling and mensurating the Se content in the Se-enriched barley seedlings. Methods:Barley se-edlings were cutivated with water and enriched Se by soaking seeds with Se,cultivating after sprouting with Se and cultivating in the whole process with Se. The Se enriched in barley seedling was assayed by atomic fluorescence spectrometry. Results:The barley seedlings cultivated with Se-after sprouting grow well when Na2SeO3 concentration is below 50 mg/L. The Se content is the highest when adding Na2SeO3 after sprouting. The organic Se content and the total Se content of the barley seedling are as 8.05 times and 4.97 times as that of control respectively when Na2SeO3 concentration is 30 mg/L. The barley seedlings grow slowly when Se is added in the whole process. Conclusion:Eriching Se with 30 mg/L Na2SeO3 after sprouting is the best way.
