Global research output on Rhododendron publications based on Web of Science database

A scientometric study

Abstract

Purpose: This study aims to conduct a comprehensive analysis of research publications on Rhododendron from the Web of Science Core Collection database.

Methodology: A total of 3082 records from 1989 to 2022 were extracted from the Web of Science Core Collection database. The data analyzed using MS Excel and VOS viewer software was used to determine the most frequent keywords used in the publications.

Findings: The analysis shows that the number of research publications on Rhododendron has been increasing steadily over the years. The year 2022 recorded the highest number of publications (213), indicating growing interest and continued research activity in this specialized area. The top 10 most prolific authors are dominated by individuals from China, with Li Yong leading with 26 publications. The United States Department of Agriculture, Agricultural Research Service, and Mae Fah Luang University ranked second and third, respectively, among the most productive organizations. China emerged as the most prolific country in terms of the number of research publications on Rhododendron, followed by the United States and India. The keywords most frequently occurring in the publications include "rhododendron," "Ericaceae," and "plants," reflecting the central focus of research in this area.

Research limitations: The findings of the study are limited to the data available in the Web of Science Core Collection database from 1989 to 2022.

Originality/Value: The findings contribute to a better understanding of the scientific landscape within this field and can help in shaping future research directions and discoveries related to Rhododendrons.
