摘要: 采用亚硒酸钠(Na2SeO3)溶液浸泡-去离子水喷淋培养的方式,研究东北及江苏大豆品种发芽富硒情况。结果表明:在30mg/L Na2SeO3溶液中,25℃恒温浸泡6h富硒发芽条件下,不同品种大豆对硒的耐受能力及其富集能力差异显著,东北大豆YH-NJ的生长特性最好、富硒量最高。随着Na2SeO3浸泡液的质量浓度、温度的升高和浸泡时间的延长,该优选品种豆芽中总硒含量呈增加趋势。

Abstract: Selenium accumulation in germinating soybean varieties from the Northeast and Jiangsu province was investigated by Na2SeO3 solution soaking-deionizer water spraying method. The results indicated that under the same selenium-enriched conditions (30 mg/L of Na2SeO3 solution, 25 ℃ constant temperature and 6 h soaking time), different varieties of soybean had different selenium tolerance and enrichment capacity. Northeast soybean YH -NJ had the best growth properties and the highest selenium content. With the increase of Na2SeO3 concentration and temperature and the prolongation of soaking time, selenium content in sprouts of soybean YH -NJ increased significantly.

Key words: soybean, germination, selenium
