摘　　要：为筛选适合鄂尔多斯高原地区的文冠果优良种源,本研究在达拉特旗对13个种源文冠果株高、地径进行对比试验。结果显示:13个种源文冠果的株高、地径存在显著差异(P<0.05)。依据株高生长优势筛选出6个较优种源,依据地径生长优势筛选出7个较优种源。利用最短距离法和最长距离法,通过株高、地径对不同种源文冠果进行聚类分析,进而可将13个种源文冠果划分为生长较优、良好和较差3类。结合文冠果株高、地径生长比较及聚类分析结果,初步筛选出内蒙古敖汉旗(NCA)、内蒙古阿鲁科尔沁旗(NCK)、内蒙古红山区(NCH)、内蒙古准格尔旗(NEZ)、陕西靖边县(SYJ)、内蒙古巴林左旗(NCB)6个较优种源。研究结果可为鄂尔多斯高原地区文冠果良种选育和种源筛选提供基础。The height and basal diameter growth characteristics of Xanthoceras sorbifolia from 13 provenances were studied in Dalad Banner in order to select excellent provenances adapted to Ordos Plateau.The results showed that there were significant differences in plant height and basal diameter among 13 provenances(P<0.05).Six superior provenances were selected according to plant height growth advantages,and seven superior provenances were selected according to basal diameter growth advantages.Through the shortest distance method and the longest distance method,the cluster analysis of Xanthoceras sorbifolia from different provenances was carried out by using plant height and basal diameter.The analysis results can divide Xanthoceras sorbifolia from 13 provenances into three categories:the best growth,the good growth and the poor growth.Based on the comparison of plant height and basal diameter growth characteristics of Xanthoceras sorbifolia and the results of cluster analysis,six superior provenances including Aohan Banner(NCA),Ar Horqin Banner(NCK),Hongshan District(NCH),Jungar Banner(NEZ),Jingbian County(SYJ)and Bairin Left Banner(NCB)were initially screened.The results can provide a basis for improved variety breeding and provenance selection of Xanthoceras sorbifolia in Ordos Plateau.
