| 中文摘要: |
| 为探究假臭草入侵海南岛的途径，研究了海南岛与粤西假臭草的亲缘关系。选择海南和广东的8 个假
臭草居群，研究了居群之间的遗传多样性、形态学和生物量分配特征。根据遗传多样性的聚类分析发现院海南岛的5
个居群聚为第1 组，广东省的阳江（YJ）和徐闻（XW）2 个居群聚为第2 组，广东鹤山HS与第2 组的亲缘关系比第1
组（海南组）更近一些。第2 组与海口HK三亚SY居群亲缘关系比琼海（QH）、琼中（QZ）、儋州DZ3 个居群更近结合遗传多样性的聚类分析、形态学特征和生物量分配特征分析8 个居群假臭草的亲缘关系，为研究假臭草入侵海
南岛的途径提供理论依据。 |
| 英文摘要: |
| In order to explore the pathway of Eupatorium catarium invading Hainan Island, we studied the relationship
of the species from Hainan Island and west Guangdong province. We selected 8 populations of E. catarium in Hainan
Island and Guangdong for the study on the genetic diversity, morphology and the characteristics of biomass distribution
among them. Based on the dendrogram analysis of genetic distance, we found that the 5 populations from Hainan Island
were in the first cluster, and the 2 populations from Yangjiang (YJ) and Xuwen (XW) in Guangdong province were in the
second cluster. The population from Heshan (HS) was nearer to the second cluster than the first. The second cluster was
nearer to the populations from Haikou (HK) and Sanya (SY) than the other 3 populations, i.e. Qionghai (QH), Qiongzhong
(QZ) and Danzhou (DZ) from Hainan Island. Combining the dendrogram analyses of characteristics of morphology and
biomass distribution, can provide a theoretical basis for the study of pathways of E. catarium invading Hainan Island. |
