    香棕(ArengaengleriBecc.),又名矮桄榔、山棕,是我国原生的桄榔属植物,近年来,由于生境的人为破坏和片断化,我国原生的香棕资源正急剧减少。本文对香棕的自然分布情况及其生境进行了野外调查,并采用ISSR分子标记技术对我国福建省和台湾境内的原生种群,以及福建省厦门、广东省广州和深圳引种的香棕种群,进行了遗传多样性水平及种群遗传结构的研究,并在此基础上,探讨香棕资源的保护策略。另外,采用ITS区域测序的方法,研究了香棕与同属其它8种桄榔属植物分子系统关系。主要结果如下: 采用改良的CTAB法成功地提取了棕榈科桄榔属植物基因组DNA,制备的DNA纯度和质量均较高,适用于ISSR-PC...In recent years, due to habitat desruction and fragmentation, our native resources Arenga engleri is facing extinction. In this paper, based on the field investigation, note of specimen and literatures, the living environment of populations Arenga engleri were probed. The genetic diversity and population genetic structure of 10 natural populations of Arenga engleri , distributed in Fujian、Guangdon...学位:理学硕士院系专业:生命科学学院生物学系_发育生物学学号:2172006115216
