【摘要】 为全面了解外源物在植物非生物胁迫领域的研究概况，本研究利用Web of Science Core Collection数据库，以“stress”和“exogenous”为标题，检索2000—2023年收录的高质量论文，精简后共计1172篇文献，进行数据分析，采用文献计量学方法，并结合BibExcel和VOSviewer进行数据可视化。结果表明，亚洲国家（尤其是巴基斯坦、印度和中国）对该领域贡献突出，University of Agriculture of Faisalabad、中国科学院和西北农林科技大学是主要研究力量。自2018年以来，该研究领域进入迅速发展阶段，论文发文量占总发文量比例达到62.1%。南京农业大学的Guo Shirong是该研究方向的代表性专家，H指数是为15。褪黑素是目前研究最为广泛的外源物质，而微生物来源的植物保护剂有望成为未来减缓非生物胁迫的研究热点。本研究通过量化分析，揭示了外源物缓解作物非生物胁迫效应的研究趋势与热点，为最大化开发非生物胁迫下作物产量潜力提供参考依据，并为未来研究方向提供了有价值的线索。现有研究对外源物作用机制的解析尚不充分，未来可进一步加强分子层面的机制研究，并深入探索微生物源植物保护剂的开发与应用。更多还原

【Abstract】 In order to comprehensively understand the research status of exogenous substances in the field of abiotic stress in plants, we used bibliometric method to search for 1172 high-quality papers in the field of exogenous substances affecting abiotic stress in the Web of Science Core Collection database from 2000 to 2023 under the headings of “stress” and “exogenous”, and we used BibExcel and VOSviewer to analyze the 1172 papers retrieved papers. The results show that Asian countries such as Pakistan, India, and China have contributed the most to this research area, and the institutions with the highest academic output are the University of Agriculture Faisalabad, Chinese Academy of Sciences, and Northwest A&F Univeristy. Since 2018, this research area has shifted from steady growth to a phase of rapid development, the proportion of paper output to the total number of published papers reached 62.1%. Among them, Guo Shirong from Nanjing Agricultural University is the expert in this research area with an H-index of 15. The most studied exogenous substance is melatonin, and microbial-derived plant protectants are expected to be the next hot research direction for abiotic stress mitigation. Through quantitative analysis, this study reveals the research trends and hotspots of exogenous substances to alleviate the effects of crop abiotic stress, provides a reference for maximizing the development of crop yield potential under abiotic stress, and provides valuable clues for future research directions. The existing research on the mechanism of action of exogenous substances is not sufficient.In the future, the mechanism research at the molecular level can be further strengthened, and the development and application of microbial plant protective agents can be further explored.更多还原
