随着全球气候变化导致干旱强度和频率的增加,以及日益严重的土壤盐渍化问题,这些因素显著影响作物生长,产量,和对逆境的韧性。燕麦是一种广泛生长在温带地区的谷物,具有丰富的营养价值;然而,有关燕麦对干旱和盐胁迫反应的科学文献尚未详细分析。本研究全面分析了燕麦对干旱胁迫和盐胁迫的响应,使用来自WebofScience核心数据库的数据和使用R(4.3.1版)的文献计量学方法,VOSviewer(版本1.6.19),和Citespace(6.3.1.0版)软件。出版物的数量显示,在过去的30年中,燕麦的干旱胁迫和盐胁迫呈上升趋势。在干旱胁迫研究领域,中国,美国,加拿大在文献出版方面处于领先地位,学术成果最多的是中国农业大学和加拿大农业食品大学。发表论文最多的杂志是田间作物研究。燕麦研究主要关注增长,产量,生理和生化反应,以及提高抗旱能力的策略。耐旱基因型的筛选和耐旱基因的转化可能是未来燕麦干旱研究的关键方向。在盐胁迫研究领域,来自中国的贡献,美国,印度脱颖而出,中国农业科学院和内蒙古农业大学取得了最显著的研究成果。已发表的文章数量最多的是《生理学植物》杂志。当前燕麦盐胁迫研究主要涵盖生长,生理和生化反应,和耐盐机制。预计未来燕麦盐的研究将更多地集中在生理和生化反应上,以及基因编辑技术。尽管在单一压力条件下取得了成就,干旱和盐胁迫对燕麦的综合影响仍未得到充分研究,需要未来研究它们在各种生物水平上的相互作用。本研究的目的是为燕麦干旱和盐胁迫的研究提供潜在的理论方向。
With global climate change leading to increasing intensity and frequency of droughts, as well as the growing problem of soil salinization, these factors significantly affect crop growth, yield, and resilience to adversity. Oats are a cereal widely grown in temperate regions and are rich in nutritive value; however, the scientific literature on the response of oat to drought and salt stress has not yet been analyzed in detail. This study comprehensively analyzed the response of oat to drought stress and salt stress using data from the Web of Science core database and bibliometric methods with
R (version4.3.1), VOSviewer (version 1.6.19), and Citespace (version6.3.1.0) software. The number of publications shows an increasing trend in drought stress and salt stress in oat over the past 30 years. In the field of drought-stress research, China, the United States, and Canada lead in terms of literature publication, with the most academic achievements being from China Agricultural University and Canadian Agricultural Food University. The journal with the highest number of published papers is Field Crops Research. Oat research primarily focuses on growth, yield, physiological and biochemical responses, and strategies for improving drought resistance. Screening of drought-tolerant genotypes and transformation of drought-tolerant genes may be key directions for future oat drought research. In the field of salt-stress research, contributions from China, the United States, and India stand out, with the Chinese Academy of Agricultural Sciences and Inner Mongolia Agricultural University producing the most significant research results. The largest number of published articles has been found in the Physiologia Plantarum journal. Current oat salt-stress research primarily covers growth, physiological and biochemical responses, and salt-tolerance mechanisms. It is expected that future oat salt research will focus more on physiological and biochemical responses, as well as gene-editing techniques. Despite achievements under single-stress conditions, combined drought and salt-stress effects on oat remain understudied, necessitating future research on their interaction at various biological levels. The purpose of this study is to provide potential theoretical directions for oat research on drought and salt stress.
