摘要:

根系分泌物是植物与土壤之间物质交换和信息传递的重要载体。为深入了解植物根系分泌物研究的现状和发展趋势,本研究采用Web of Science核心合集数据库中1998-2020年间有关植物根系分泌物研究的相关文献4047篇,基于CiteSpace软件进行可视化文献计量学分析。结果表明:1)有关植物根系分泌物的发文量、篇均被引次数呈典型线性增长;2)中国、美国、德国、日本、澳大利亚和法国等是发文量居前的国家;3)中国科学院、南京农业大学、西班牙国家研究委员会、西澳大学等机构在发文总量、被引次数等方面优势明显。有关植物根系分泌物的研究涉及植物科学、土壤科学、农学、环境科学、微生物学和生态学等领域,最具代表性的是荷兰期刊《Plant and Soil》,发表文章最多(256篇),h指数最高;4)植物根系分泌物的研究主要集中在根际、植物、土壤、有机酸、化感作用等方面。根据植物根系分泌物的研究现状,提出深入系统地研究根系分泌物介导下植物-土壤-微生物相互作用的方式与机理,揭示土壤微生态系统功能,定向调控植物根际生物学过程是近年来新兴的研究热点。

Abstract:

Root exudates are important carriers for substrate and metabolite exchange and information transmission between plants and soil. This study accessed a total of 4047 publications on root exudates in the core journals whose contents were included in Web of Science from 1998 to 2020, and used CiteSpace software to identify research themes and topics of current interest. It was found that: 1) The total publications and average citations per paper of the surveyed research showed a linear increase with time; 2) Institutions from the USA and China were the most active in this field, followed by Germany, Japan, Australia and France, occupied the most dominant positions; 3) Chinese Academy of Sciences, Nanjing Agricultural University, CSIC, and University of Western Australia are obvious leaders in terms of the total number of publications and average citations per research paper. Plant Sciences, Soil Sciences, Agronomy, Environmental Sciences, Microbiology and Ecology were the most frequently used subject categories. The Netherlands journal Plant and Soil is a clear leader in the total number of publications (256) and h-index, and thus very influential in academia; 4) Plant root exudates research was most often linked with keywords “rhizosphere”, “plant”, “soil”, “organic acid”, and “allelopathy”. Finally, based on current research, we infer that future research will move towards a focus on plant-soil-microbe interactions and mechanisms mediated by root exudates, and this will have important implications for elucidating the dynamics of rhizosphere microecology and for providing practical guidelines for plant culture and crop husbandry.
