摘　　要：利用无患子种仁制备生物柴油,是当前生物质资源产业化的热点领域之一。为筛选出无患子油脂高产优树,对分布在福建、江西、浙江、安徽、湖南、广西和云南等7省区的61株优树进行种仁含油率测定,并对种仁含油率在平均水平之上的29株优树进行了聚类分析,同时还采用灰色关联度分析法分析了树龄、树高、胸径、冠幅面积以及优树所处区域的年平均气温、年降水量、海拔高度等因素对无患子种仁含油率的影响。结果表明,含油率最高的优树为位于江西大余的98#优树,达58.60%,无患子种仁含油率与各影响因素之间的关联度最大的是优树所处区域的年平均气温,其次是海拔高度,再其次分别是优树的树高、胸径、树龄、优树所在区域的年降水量、优树的冠幅面积。Using the seed kernel of Sapindus mukurossi producing biodiesel is one of the hot areas in biomass resources industry at present. In order to select high oil yield plus trees, the oil contents in seed kernels from 61 S. mukurossi plus trees were measured, which come from Fujian, Jiangxi, Zhejiang, Anhui, Hunan, Guangxi and Yunnan provinces. The cluster analyses were carried out on 29 plus trees that oil contents in seed kernels were above the average of the 61 plus trees. Meanwhile, the effects of tree-age, height, diameter, crown area and the annual mean temperature, annual precipitation, altitude in the regional of plus tree on oil contents in seed kernels of S. mukurossi were investigated by applying grey correlation analysis method. The results show that the highest oil-yield tree is the 98# plus tree locating in Daiyu county, Jiangxi province, which oil content was 58.60%;The annual mean temperature is the highest correlation with the oil content of the seed kernels of S. mukurossi, next was altitude, and in turn, followed by tree height, diameter, age, annual precipitation and crown area.
