Based on bibliometrics， the research overview， cutting－edge trends and research cooperation of plant glandular trichomes from 1991 to 2021 were analyzed through the CNKI and Web of Science （WOS） databases， with the help of literature information visualization analysis software VOSviewer and CiteSpace system， in order to provide scientific support and theoretical reference for related research in the field of plant glandular trichomes. The results show that the number of Chinese literature publications has shown a general downward trend in recent years， while the number of English literature publications has increased year by year. The hotspots in Chinese literature mainly focus on the study of the chemical composition of glandular trichome secretions of agricultural crops such as tobacco and medicinal plants such as Artemisia annua， while English literature is more concentrated on the biosynthesis of secondary metabolites in glandular trichomes and gene expression related to glandular development. In terms of research cooperation， there is close cooperation among the institutions publishing English literature， but the research topics are highly independent. In contrast， while the themes of literature publication from Chinese publishing teams have strong thematic associations and a lot of cross－collaboration. In the future， domestic research on plant glandular trichomes may focus on cultivating new varieties through techniques such as gene editing， increasing the yield of target metabolites， and providing guidance production applications.
