以11个黄连木天然群体为试材,对18个表型性状的变异与多样性进行分析,结果表明:黄连木表型性状存在极其丰富的群体间和群体内变异,各性状间的变异系数相差较大,变幅为4.249%~27.31%,果实性状的变异系数最小,受较高的遗传控制。群体间平均表型分化系数VST为22.27%,说明群体内变异是黄连木遗传变异的主要来源,采用聚类分析的方法,把11个群体分为4类,表型性状与地理气候因子相关分析表明除百果重、千粒重、种长几个性状外,多数表型性状随地理位置的改变没有明显的变化,但有随着经度、纬度的增加而逐渐增大趋势。
The results showed that the phenotypic traits of Pistacia chinensis were extremely rich in intraspecies and intraspecies and the coefficient of variation The difference is larger, the amplitude is 4.249% ~ 27.31%, the coefficient of variation of fruit traits is the smallest, controlled by higher genetic. The average phenotypic differentiation coefficient (VST) of the population was 22.27%, which indicated that intraspecies variation was the main source of genetic variation in Pistacia chinensis. Cluster analysis was used to classify 11 populations into 4 groups. Correlation analysis between phenotypic traits and geographical climatic factors The results showed that most phenotypic traits did not change obviously with the change of geographical position except for the fruit weight, 1000-grain weight and seed length, but increased gradually with the increase of longitude and latitude.
