AbstractTo understand the research hotspots and trends inthe field of maize drought stress studies，this paper used 1842 articles published between 1994 and 2O23fromthe Webof Science databaseas samples，and conducted a visual analysis of thepublication output and keywords using CiteSpace software.The results showed that：（1）The developmenttrendof this fieldfrom1994 to 2023can bedivided into three stages： the embryonic period（1994-2007）， theslowdevelopment period （2008-2015），and the explosive growth period （2016-2023），with the numberof publications showing an exponential growth trend. （2） Keyword clustering analysis revealed that the keywords in this field formed 9 clusters，generating 6research hotspots covering 3 aspects： biological phenotypes （yield characteristics， growthand development），physiological responses （oxidative stress，gene transcription，and wateruseeficiency）and mitigation measures （drought resistance）. （3）Keyword burst analysis indicatedthattheresearch themes inthe embryonic period focusedon abscisic acid regulatory mechanisms，genetic traits，and yield characteristics;those in the slow development period centered on the improvement of maize drought tolerance under climate change; and the research themes inthe explosive growth period were water use，gene expresion，and the drought-resistant mechanismof salicylic acid.Overall，water use，geneexpression，and the drought-resistant mechanismof salicylicacid in maize underdrought stress may remain frontier research directions in the future.This study provides areferencefor maize drought resistance

research.
