Analysis of world cherry research trend based on bibliometrics.

Based on the Web of Science database and using biblionmetric method,this paper analyzed the trend of published cherry literature in the world from 2000 to 2013,and also reviewed the research institutes,core authors,key journals,subject categories and research hot spots of the countries with published paper quantity ranking at world top 5.The result indicated that there were 1 794 cherry research papers all over the world.The paper production as a whole showed a rising trend,with the top quantity in 2012,which was almost 2.288 times of that in 2005.The top 5countries were the United States,Turkey,Spain,Germany and Italy.The United States published 376 papers,taking the first place.Except Germany,the other 4 coutries were among the world top 5 in cherry production,illustrating that their strong scientific research ability did promote the development of cherry industry.The world top 5 institutions with high cherry academic paper quantity were USDA-ARS,Michigan State Unversity,Washington State University,Agriculture Agri-Food Canada,and University of Extremadura in Spain.The core authors with high academic achievement were mainly from the United States. "Scientia Horticulturae", " Hortscience", "Journal of Agricultural and Food Chemistry", "Postharvest Biology and Technology" and "Food Chemistry" were the major journals in this field.The main disciplines of these published cherry literature were agriculture,food science technology,plant science,chemistry and environmental science ecology.The research hot spots were focused on fruit quality,disease,anthocyanin,rootstock and post harvest mechanism.
