Key words Domestic and foreign studies,Banana,Scientific research,Literature

1 Introduction

The inclusion of scientific literature in the international authoritative retrieval system is a comprehensive reflection of the country’s academic status.Scientific papers are historical records of scientific and technological development,and also important basis for the development level and development trend of science and technology.They play an important role in promoting scientific research and technological progress[1-3].Nowadays,the SCI-EXPANDED and EI databases are recognized as the most authoritative scientific and technical literature retrieval tools in the world[4-5].Based on the literature included by SCI-EXPANDED and EI database,we compared and analyzed the main research literatures of bananas both at home and abroad in 2013-2014.We compared the advances in domestic and foreign studies about the banana from main counties,number of papers included,main disciplines and fields,in order to provide certain guidance and references for development direction of domestic studies of banana in China.

Retrieval method: we selected SCI-EXPANDED and EI databases,the retrieval range was the literature title,the connection word used OR,and selected the common word "banana" used in domestic and foreign scientific literature,and the retrieval time was January 2015.

3 Comparison and analysis of domestic and foreign studies of banana

The domestic studies about banana are less than foreign studies of banana.Both domestic and foreign studies of banana are mainly Food Science and Technology,Plant Science,Agronomy,and Biotechnology & Applied Microbiology and Chemistry disciplines.Foreign studies mostly involve the evaluation of antioxidant activity of banana inflorescence extracts,drying characteristics and physical and chemical properties of dry cooking banana slices,optimization of microwave drying conditions of banana varieties by application of response surface methodology (RSM),visualization of internal structure of banana starch granules by atomic force microscopy,and banana anthrax differential gene expression analysis of resistant banana varieties after bacterial infection,genetic structure and genetic diversity of banana bunchy top virus population,and effects of nutrient deficiency on banana yellow banana leaf spot diseases.These areas are not reported in domestic literature.By comparison,domestic studies mostly involves the effects of nitric oxide (NO) on energy metabolism under post-harvest banana fruit under low temperature stress,the effect of 1-MCP and ethylene combination treatment on banana fruit ripening,banana root knot nematode,multi-site sequence analysis of banana soft rot fungus and biochemical characteristics,hydrogen sulfide (H2S) enhanced antioxidant system and proline content reducing low temperature damage of banana fruit,etc.
