【摘要】 在田间试验条件下,研究了华北贫硒地区不同谷子品种叶面喷施亚硒酸钠对籽粒硒含量及其蛋白质、可溶性糖、赖氨酸的影响。结果表明:两种(60g/hm2和120g/hm2)叶面施硒处理,可使该地区谷子籽粒硒含量分别达到1.022~1.644,1.853~2.269mg/kg,是未施硒的15.4,23.8倍,但对籽粒产量的影响无显著差异。叶面施硒增加了多数试验品种籽粒中蛋白质含量,表现出显著差异;叶面喷施使冀谷22籽粒中可溶性糖和赖氨酸含量显著增加,使晋谷34籽粒中可溶性糖明显减少,对其他品种可溶性糖和赖氨酸含量的影响均无显著差异。

【Abstract】 The field experiment was carried out to study the effects of foliar application of Na2SeO3 on contents of Se,protein,soluble sugar and lysine acid in grains in low Se region of North China. The results showed that the two treatments of foliar application of Na2SeO3 60 g/ha and 120 g/ha could increase Se contents in grains of the seven varieties of millet up to 1. 022-1. 644 mg/kg and 1. 853-2. 269 mg/kg,which were 15. 4 and 23. 8 times higher than those in control treatment respectively. Moreover,the grain yields of the seven varieties of millet showed negative correlation with the contents of Se in grains. There was significant increase protein contents in most the varieties of millets with foliar application of Na2SeO3. The soluble sugar and lysine acid in grains of Jigu22 were increased significantly by foliar application of Na2SeO3,but the soluble sugar of Jingu34 was reduced significantly,while there was no significant effects on the other varieties of millet.
