Abstract Selenium (Se) is beneficial element while, zinc (Zn) is an essential micronutrient for both plants and humans. A deficiency of these elements in the human body will result in a series of severe and adverse consequences. The aim of this study was to investigate the concentrations of Se and Zn in seven different genotypes of wheat under organic and inorganic (conventional) fertilization trials. The experiment was a completely randomized block design (RCBD) with four replications. Se and Zn concentrations were measured with ICP-OES. The conventional system exhibited the highest grain yield. However, the concentrations of Zn and Se were higher under organic than conventional fertilization treatments. The main effect of wheat genotypes showed that the IC8 genotype had the highest mean concentration of Se (1440 µg kg−1), while the local genotype had the highest mean concentration of Zn (51.7 mg kg−1). These two genotypes can be considered good sources of nutrition. The interaction effect showed that the ICARDA genotypes (IC8 and IC17) had the greatest Se and Zn concentrations, respectively, under organic fertilization, while the Egyptian genotype (Sids12) had the highest and lowest Se concentrations in conventional and organic fertilization, respectively. The results showed differences in Se and Zn concentrations among different wheat genotypes in response to organic verses conventional fertilization treatments.

有机和无机施肥条件下春小麦 (Triticum aestivum) 基因型的硒和锌浓度

摘要 硒 (Se) 是有益元素，而锌 (Zn) 是植物和人类必需的微量营养素。人体内缺乏这些元素会导致一系列严重的不良后果。本研究的目的是在有机和无机（常规）施肥试验下调查七种不同基因型小麦中硒和锌的浓度。实验是完全随机区组设计 (RCBD)，重复四次。使用 ICP-OES 测量 Se 和 Zn 浓度。传统系统表现出最高的谷物产量。然而，有机施肥处理中锌和硒的浓度高于常规施肥处理。小麦基因型的主效应表明，IC8 基因型的硒平均浓度最高（1440 µg kg−1），而当地基因型的锌平均浓度最高（51.7 mg kg-1）。这两种基因型可以被认为是良好的营养来源。互作效应表明，ICARDA 基因型（IC8 和IC17）在有机施肥下分别具有最大的Se 和Zn 浓度，而埃及基因型（Sids12）在常规和有机施肥下分别具有最高和最低的Se 浓度。结果表明，不同小麦基因型对有机施肥和常规施肥处理的硒和锌浓度存在差异。在有机施肥下，埃及基因型 (Sids12) 在常规和有机施肥中分别具有最高和最低的硒浓度。结果表明，不同小麦基因型对有机施肥和常规施肥处理的硒和锌浓度存在差异。在有机施肥下，埃及基因型 (Sids12) 在常规和有机施肥中分别具有最高和最低的硒浓度。结果表明，不同小麦基因型对有机施肥和常规施肥处理的硒和锌浓度存在差异。
