摘　　要：高质量的牧草种子是我国草牧业发展和生态改良的物质基础。种子活力是评价种子质量的重要方面。高效的牧草种子活力评价方法可筛选出高质量种批用于人工草地建植与天然草地改良,对保障国家食物与生态安全具有重要意义。国内外学者已就牧草种子活力评价的不同方法及其与田间出苗生产表现之间的联系开展了众多研究。本研究就牧草种子活力的概念及评价方法进行综述,重点从牧草种子物理性状、萌发特征与幼苗生长、逆境试验、生理生化指标、计算机与光学成像新技术等几个方面,论述其测定原理和在牧草种子活力评价上的应用现状,并提出未来的研究展望。以期为下一阶段牧草种子活力基础研究与测定提供重要理论依据与参考。High-quality forage seeds are fundamental materials for grass-husbandry industry development and ecological restoration in China.Seed vigor is an important aspect of evaluate seed quality.The efficient vigor estimation of forage seeds is of great importance for selection of high-quality seed lots for cultivated grassland establishment and improvement of natural grassland,and is therefore critical to ensuring food and ecological security.Numerous studies on diverse forage seed vigor estimation methods and their ability to predict field performance have been carried out and published.In this study,the concepts and methodologies for forage seed vigor estimation are summarized,with particular emphasis on the estimation principles and their application in forage seed vigor estimation of some of the more commonly used methods.Coverage of this review includes forage seed physical properties,germination and seedling growth characteristics,stress testing,physiological and biochemical indicators,and advanced technologies.Future prospects in this field are also identified and discussed,to provide necessary direction for the improvement of future research.
