摘　　要：该研究选择我国7个杜仲产地的杜仲为研究对象,采用随机取样的方法,利用SPSS软件进行统计分析。结果表明:不同产地果实形态和含胶量存在显著差异,贵州剑河最高为13.16%,河北保定最低为9.34%,含胶量与所在环境气候条件密切相关,纬度越高,年日照时数越长,翅果含胶量越低;无霜期越长,翅果含胶率越高。In this study,the Eucommia samara of 7 producing areas in China were selected as research objects,random sampling method was adopted,and statistical analysis was carried out by SPSS software.The results showed that there were significant differences in fruit morphology and Gutta-percha content among different producing areas,which were closely related to the environment and climate conditions.Jianhe,Guizhou,with a high of 13.16%,and Baoding,Hebei,with a low of 9.34%.The higher the latitude and the longer the annual sunshine hours,the lower the Gutta-percha content of samara.The longer the frost-free period,the higher the gum content of samara.
