Seed traits (ST) influence seedling establishment, population dynamics, community composition and ecosystem function and reflect the adaptability of plants and the environmental conditions they experienced. There has been a historical and global accumulation of studies on ST, but with few pertaining to visual and quantitative analyses. To understand the trends in the field of ST research in the past 30 years, we conducted a bibliometric analysis based on the Science Citation Index-Expanded (SCI-E) database. The analysis provided annual publications, time trends for keywords, the most productive journals, authors, institutions and countries, and a comprehensive overview of the ST field. Our results showed that in the past 30 years, the number of publications in ST research has increased at an average annual growth rate of 9.1%, while the average number of citations per paper per year showed a rapid increase-slow increase-decrease trend. Keyword analysis showed that "germination" was the most popular research section. ranked first among the top journals and had greater influence in this area and more citations than other journals. The 10 most productive institutions were mostly located in the United States, China and Australia. Furthermore, the three countries also had the largest number of publications and citations. Our analysis showed that the research interests in ST have evolved from genetics and agricultural science to ecological research over the last thirty years; as more fields embrace ST research, there are opportunities for international and interdisciplinary collaborations, cooperative institutions and new advances in the field.
种子性状（ST）影响幼苗建立、种群动态、群落组成和生态系统功能，并反映植物的适应性以及它们所经历的环境条件。关于种子性状的研究在历史上和全球范围内都有积累，但涉及视觉和定量分析的研究较少。为了解过去30年种子性状研究领域的趋势，我们基于科学引文索引扩展版（SCI-E）数据库进行了文献计量分析。该分析提供了年度出版物、关键词的时间趋势、发文量最多的期刊、作者、机构和国家，并对种子性状领域进行了全面概述。我们的结果表明，在过去30年中，种子性状研究的出版物数量以年均9.1%的速度增长，而每年每篇论文的平均被引次数呈现出快速增长-缓慢增长-下降的趋势。关键字分析表明，“萌发”是最热门的研究方向。在顶级期刊中排名第一，在该领域比其他期刊具有更大的影响力和更多的引用。发文量最多的10个机构大多位于美国、中国和澳大利亚。此外，这三个国家的出版物和被引次数也最多。我们的分析表明，在过去三十年中，种子性状的研究兴趣已从遗传学和农业科学转向生态研究；随着更多领域开展种子性状研究，国际和跨学科合作、合作机构以及该领域的新进展都存在机遇。
