  7. The dissertation consists of five chapters : in chapter one, the recent progress in molecular approaches in systematic studies of macroalgae e. g. dna extraction, restriction endonuclease fragment length polymorphisms ( rflps ), random amplified polymorphic dna ( rapd ), gene sequencing, intersimple sequence jepeats ( issr ), amplified fragment length polymorphisms ( aflp ) and single strand. conformation polymorphisms ( sscp ) were reviewed

    本論文由五部分組成：在第一部分，綜述了大型海藻dna的提取、限制性片段長度多態性（ rflps ） 、隨機擴增多態性dna （ rapd ） 、核酸序列分析、擴增片段長度多態（ aflp ） 、單鏈構象多態（ sscp ）等分子手段在大型海藻系統學研究中應用的一些進展。
  8. Primers of ecori were signed with fluorescent dye and four pairs of primers were selected from twenty - four pairs. 261 dna fragments were generated by the four pairs of primers in forty - three individuals sampled. percentage of polymorphic bands is 51 %, the value of shannon index ( i ) is 0. 086 and nei ' s gene diversity ( h ) is 0. 151

    統計這些aflp表型帶標記，用popgene軟體計算各種多樣性數據（ ppb值為51 ， shannon多樣性指數為0 . 086 ， nei ' s基因多樣性值為0 . 151 ） ：用ntsys軟體計算各個樣品間的相似性系數，並用upgma法基於相似性系數進行聚類分析，構建樹狀圖，它們可反映出元寶山冷杉種群內個體間的遺傳關系。
