为了筛选适宜叶面喷施硒强化的理想品种,对63个近年来长江中下游主推小麦品种(系)进行叶面喷施硒酸钠,强化浓度为300mg Se/L(Se300),利用离子发射光谱-原子吸收仪测定了小麦籽粒中Se、Cu、Fe、Mn、Zn、K、Mg、K和S含量. 结果显示,叶面喷施硒酸钠可以提高小麦籽粒中的硒含量,总硒含量平均值由对照组的2.13±0.73mg/kg提高到9.13±3.86mg/kg,但增幅因品种而异;籽粒中不同矿物质元素对叶面喷施硒酸钠的响应不同,硒降低了籽粒中Cu、Fe、K、Mg和S的含量,但提高了锌的含量,对Mn和Ca元素含量没有影响. 综合比较显示江麦816是长江中下游主要推广品种中硒强化潜力较大的品种(系)之一.“,”In order to select ideal varieties suitable for follage spraying selenium (Se) biofortification in grains of different wheat cultivars in Middle and Lower Reaches of the Yangtze River, 300 mg Se/L(Se300) foliar fertilizer was sprayed uniformly onto 63 wheat cultivars during booting-heading stages. The contents of Se, Cu, Fe, Mn, Zn, Ca, K, Mg, P and S were measured using ICP. The results indicated that follage spraying selenate increased significantly Se content in wheat grains. The average value of total Se content increased 2.13±0.73 mg/kg to 9.13± 3.86 mg/kg then contrast, but the amplification varied among cultivars. Different mineral elements in grains responded differently to follage spraying selenate, decreasing the contents of Cu, Fe, K, Mg, and S in grains, but increasing Zn contents, and having no effect on Mn and Ca contents. Comprehensive comparison showed that'Jiangmai 816' was one of the cultivars mainly popularized in Middle and Lower Reaches of the Yangtze River with larger Se biofortification potential.
