| 摘 要： | 对采自黑龙江省平顶山和吉林省长白山的14 个天然居群高山红景天的分株数、株高、基径、叶长和叶宽5 个形态性状进行了比较分析, 探讨了高山红景天适应环境的形态变异机制。单因素方差分析F 检验表明, 除分株数外的4 个形态性状在14 个居群中均表现为差异极显著。对这4 个性状的多重比较分析表明, 各形态性状在不同生态环境下表现出一定程度的分化。对14个天然居群形态性状的聚类分析表明, 高山红景天的形态变异与其生态环境间存在着明显的相关关系。

| Abstract: | The number of plant division, plant height, base diameter, leaf length and leaf width of Rhodiola sachalinensis from 14 natural populations collected in Pingdingshan of Heilongjiang Province and Changbai Mountain of Jilin Province were analysised to study the morphological variation mechanism of natural populations. Variance analysis of single factor indicates that there are significant differences in morphological indexes except branch number in 14 natural populations. Multiple comparison analysis of 4 characters shows that morphological characters in different habitats have differentiated in some degree. Cluster analysis for 14 natural populations shows that there are obvious correlations between morphological variety of Rh. sachalinensis and their habitats. |
