低温逆境已成为限制全球小麦稳产丰产与优质的主要农业气象灾害之一。为客观全面地了解全球小麦低温逆境领域的研究现状和发展趋势，基于Web of Science核心数据库中2000-2020年发表的以"小麦"和"低温"为研究主题的相关文献为数据源，利用CiteSpace可视化分析软件对检索到与主题密切相关的 475篇文献从发文数量、发文国家、发文作者、研究机构、研究热点等方面进行统计分析。结果表明:自 2000年以来，小麦低温逆境领域年发文数量总体呈波动上升趋势;以中国、美国和加拿大等国家为代表的农业大国均致力于该领域的研究;美国学者Skin-ner是该领域发文量最多的作者，与其他学者合作密切的有李向楠和Fowler;该领域文献多发表于《Molecular Genetics and Genomics》和《Annual Review of Plant Biology》等优质期刊上;俄罗斯科学院是该领域发文量最多的科研机构;耐低温小麦新品种培育、耐寒分子生物学研究以及提高小麦产质量等方面成为该领域的研究热点。
Research Trend Analysis of Global Wheat Low-temperature Stress Based on Web of Science
Low-temperature stress has become one of the main agrometeorological disasters limiting stable yield,high yield,and high quality of wheat worldwide.To objectively and comprehensively understand the research status and development trend in the field of global wheat low-temperature stress,based on the relevant documents with ″wheat″ and ″low temperature″ as the research theme published in the core database of Web of Science from 2000 to 2020,this paper used CiteSpace visual analysis software to retrieve 475 documents closely related to the theme,analyzed statistically in the respects of document number,countries,author,research institution,research hotspot,etc.The results demonstrate that the annual number of documents issued in the field of wheat low-temperature stress has shown a fluctuating upward trend since 2000;large agricultural countries represented by China,the United States,and Canada are committed to research in this field;Skinner,an American scholar,is the author with the largest number of publications in this field,and Li Xiangnan and Fowler were closely cooperating with other scholars;literature in this field is mostly published in high-quality journals such as Molecular Genetics and Genomics and Annual Review of Plant Biology;the Russian Academy of Sciences is the scientific research institution with the largest number of papers in this field;the cultivation of new wheat varieties with low-temperature tolerance,the study of cold-resistant molecular biology,and the improvement of wheat yield and quality have become the research hotspots in this field.
