摘　　要：综述了锌、铁、硒3种微量元素对小麦生长发育、产量及品质影响的研究进展,对造成小麦中微量元素含量差异的原因进行了深入分析.土壤中微量元素的植物有效性、元素间的相互影响、小麦品种的基因型差异、栽培管理措施等因素都会导致小麦籽粒中微量元素含量变化.研究基因型差异并筛选富含微量元素的功能性营养小麦品种成为今后小麦遗传育种的一项重要工作.Trace elements have an important function to both human health and plant life activity. The recent studies on the biological functions of zinc,iron and selenium,and their important roles in plant growth and development are reviewed in this paper. Certain concentration of zinc,iron or selenium can increase yield,promote growth and improve quality of wheat. Due to the inuences of environment and plant itself,zinc,iron and selenium contents vary in different wheat varieties. Detail analyses of the variation indicate that the effectiveness of trace elements in plants,interaction among elements,genotypes of wheat and cultural management might make the elements varied in plants. Investigation of genotypic difference and selection of microelement-rich plants are important for wheat breeding in the near future.
