Abstract:

Cornus spp. has high ornamental value and is mostly used for landscaping for its various bract colors, and changeable leaf colors. In order to sort out research trend of Cornus spp. in the future, based on CiteSpace software, bibliometrics method was used in this study to visually analyze the target literature on the study of Cornus spp. from 1993 to 2004 in Web of Science (WOS) and China National Knowledge Network (CNKI), and build a knowledge map. The results showed that WOS and CNKI collected 216 and 50 articles on the study of Cornus spp. from 1993 to 2004, respectively. Through the analysis of the literature collected by WOS core library, it could be seen that the top 3 countries in terms of publication volume were the United States, China and Japan. Main research institutions were United States Department of Agriculture, University of Tennessee Knoxville, University of Tennessee System, Tennessee State University, UT Institute of Agriculture and other units. The top 10 keywords mainly appeared in the fields of flowering dogwood, dogwood anthracnose, mortality, growth, identification, forest, patterns, climate change, diversity. Domestic and foreign researchers had not enough study on diseases and pests, varieties identification as well as cultivation and utilization of Cornus spp.. It is necessary to strengthen the research on the exploration and utilization of excellent varieties with strong disease resistance, high ornamental value and strong resistance.
