摘　　要：种子代表高等植物生活史中的一个重要时期,也是种质多样性资源保存的重要载体。种子在贮藏过程中的老化是不可避免的,了解种子活力或抗老化能力的分子机制对于农业生产具有重要意义。本文对数量性状位点分子标记技术、全基因组关联分析、组学技术和基因工程等在种子活力或抗老化能力的分子机制方面的研究进展进行了综述,以期为通过分子设计育种技术改良种子的活力或抗老化能力提供理论指导。Seeds represent an important period in the life history of higher plants and are also an important carrier for the preservation of plant germplasm diversity. Aging is inevitable during the storage process of seeds. Understanding the molecular mechanisms of seed vigor or anti-aging ability is of great significance in agricultural production. This article summarized the research progress of molecular mechanisms related to seed vigor or anti-aging ability from the aspects of molecular marker technology on quantitative trait loci(QTL), genome-wide association analysis, omics technology and genetic engineering. It may provide theoretical guidance for improving the vigor or anti-aging ability of seeds through molecular design breeding.
