摘要
基于野外调查和查阅标本、文献,运用相似性分析,研究江西胡颓子属植物的种类与地理分布。结果表明,江西境内共有胡颓子属植物12种1变种,江西南部与北部的胡颓子属植物种类存在差异,距27°N线越远,差异越大;江西胡颓子属植物与相邻地区胡颓子属植物相似性系数为0.4~0.81,表明江西与邻近地区胡颓子属植物区系关系密切。
Based on the data from field investigation,herbarium specimens and literatures, the species and geographic distribution of Elaeagnus in Jiangxi Province were studied by similarity analysis. The results showed that there are 12 species and 1 variety of Elaeagnus in Jiangxi Province, difference of Elaeagnus species were found between southern and northern areas of Jiangxi Province, the farther away from north latitude 27°, difference of species are larger.
