结论同种植物不同居群间亲缘关系的远近与地理来源有关；能够通过聚类分析区分姜黄和川郁金；姜黄属郁金类植物的栽培型和野生型产生了分化。
Clustering approach could make a distinction between Curcuma longa and C. sichuanensis. The differentiation has happened between the wild and cultivated species of Curcuma L.
并且4个居群的基因流值都大于2，说明基因交流防止了由遗传漂变引起的居群间的遗传分化。
And gene flows of 4 populations were over 2, which suggested that there existed sufficient genetic exchanges to prevent the genetic differentiation made by genetic drift among population.
不同组间具有极高的遗传分化，而组内居群间遗传分化不明显。
There was extremely high genetic differentiation among groups, but not significant within group.
居群间遗传分化的产生主要与居群间的基因交流受到限制有关。
Genetic differentiation among different populations is related to the limited gene communication.
POPGENE分析得出的地涌金莲的基因流为0.4916，表明各居群间存在较少的基因交流，较低的基因流是地涌金莲居群间遗传分化的重要原因。
POPGENE analysis indicated that there is very little gene flow among different populations (0.4916), which is the main reason of high genetic differentiation among M. lasiocarpa populations.
生境的片段化和基因流障碍可能是导致居群间遗传分化显著的主要原因。
The main factors responsible for the high degree of genetic differentiation among populations may result from habitat fragmentation and barriers of gene flow.
生境的片段化和基因流障碍可能是导致居群间遗传分化显著的主要原因。
