摘要：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。
Based on investigation and analysis of 11 natural pupulations of Pistacia chinensis Bunge in China,morphological variation and diversity of pupulations were studied.Variation of all 18 characteristics are significantly different among and within populations.CV among phenotypic characteristics is markably different,varying from 4.249% to 27.31%.CV of fruit traits is minimum,which is controlled mostly by genetic factors.Average phenotypic differentiation coefficient（Vst）is 22.27%,indicating that the genetic variation within population is the main sources of genetic diversity.The 11 populations are classified,according to cluster analysis,into 4 groups.Besides 100 fruit weight,1000 grains weight and seed length,there was no significant relationship between phenotypic characteristics with geographic and ecological factors,but as longitude and latitude increase,the most fruits,seeds,leaves traits increase.
