The grain yield and concentrations of Fe, Zn, Se, Cd, and P in two winter wheat genotypes and in vitro bioaccessibility of Fe and Zn under the effect of different nitrogen fertilization and Zn-Se foliar application were evaluated. The total grain Fe, Zn, and Se concentrations, as well as Fe and Zn concentrations, after in vitro digestion were under the strongest effect of foliar Zn-Se application. On the other hand, Fe and Zn bioaccessibility (%) were under the most substantial effect of genotype. Regarding the need to increase concentrations of essential micronutrients in wheat grain, foliar Zn-Se application is a reliable and accepted agricultural practice, but to improve mineral bioaccessibility in human nutrition, foliar Zn-Se application should be combined with the most responsive genotypes. For this reason, further research on the genotype specificity of wheat regarding micronutrient bioaccessibility should be carried out.
评估了两种冬小麦基因型的籽粒产量以及铁、锌、硒、镉和磷的含量，以及不同氮肥施用和锌硒叶面喷施处理下铁和锌的体外生物可利用性。体外消化后，籽粒中铁、锌和硒的总含量以及铁和锌的含量受锌硒叶面喷施的影响最大。另一方面，铁和锌的生物可利用性（%）受基因型的影响最为显著。考虑到需要提高小麦籽粒中必需微量营养素的含量，锌硒叶面喷施是一种可靠且被认可的农业措施，但为了提高人体营养中矿物质的生物可利用性，锌硒叶面喷施应与反应最敏感的基因型相结合。因此，应进一步开展关于小麦微量营养素生物可利用性基因型特异性的研究。
