| 9. | In this work , some species of palmae cultivated in the xiamen botanical garden had been selected to be analyzed their genetic diversity with rapd ( random amplified polymorphic dna ) technique . according to the result of genomic dna amplified with pcr ( polymerase chain reaction ) , genetic distance and similarity between different palm species were calculated on nei " s estimate of similarity and genetic distance . a primary but first time research at the phylogenetic relationships of some genera and species , the molecular classification and identification of some puzzling species of palmae was carried out through upgma ( unweighted pair group mean average ) cluster analysis of the genetic distance together with comparative study of the morphological structure characteristics
本文在初步调查分析了棕榈科植物在我国的自然分布、引种驯化情况以及该类植物在厦门地区栽培应用状况的基础上，首次采用rapd分子标记技术，对厦门万石植物园引种的一些棕榈科植物的遗传多样性进行了研究，根据pcr对基因组dna扩增的结果，用nei ' s相似性系数计算了不同植物间的遗传距离和遗传一致度，通过对遗传距离的upgma聚类分析，并结合形态分类的特点，对棕榈科植物的属、种间的系统分类关系和一些疑难种的分类鉴定进行了初步研究。 |
| 10. | Sixties primers were used for dna amplification and a total of 237 amplification products range from 450bp to 2500bp were generated . a similarity matrix for all pairwise comparisons was calculated using nei and li ' s formula and then transformed to distance matrix . dendrograms were constructed by applying unweighted pair - group arithmetic average ( upgma ) and neighboring - jointing cluster analyses using the phylip software
在第二部分，应用改进的ctab法提取了石莼属和浒苔属各3个种及作为对照的刚毛藻的基因组dna ， 60个引物被用于扩增，共获得237个片段大小在450 - 2500bp之间的扩增片段，依据nei和li ( 1979 )的公式计算出样品成对比较的相似性距阵并换算成遗传距离，应用phylip软件包，按照upgma法和n - j法分别构建聚类图。 |
