Endangered abies yuanbaoshanensis will probably have been extinct, so it very necessary to studying its genetic diversity with a proper way in order to save this key group of biological diversity in china
元寶山冷杉是具有重大科學價值的類群，目前它卻處于高度瀕危極待保護狀態，要有效保護和挽救這一作為我國生物多樣性的關鍵類群，選擇合適的方法來研究其遺傳多樣性是非常必要的。Abies yuanbaoshanensis is a guangxi endemic and endangered evergreen coniferous arbor, listed in the red data book of plant in p. r. c, being one of the stated - proteced first - class rare and endangered plants. it is distributed only in yuanbaoshan mountain in northern guangxi
元寶山冷杉是松科冷杉屬的常綠針葉喬木，是20世紀70年代發現的新種，它是世界上僅產于廣西融水縣北部元寶山的殘遺瀕危種，已被列為一級保護的瀕危植物。In the present study, aflp ( amplified fragment length polymorphism ) markers was used to examine population of abies yuanbaoshanensis in order to understand the level of population genetic variation and genetic structure. the result would help to evaluate its evolutionary potentiality and the degree of being endangered and could provide scientific basis for making right protection strategy. high - quality dna was extracted using ctab method from those tender leaves of forty - three fully - developed trees in population abies yuanbaoshanensis
本研究選用一種高效的檢測遺傳變異的分子標記? ? aflp技術來分析元寶山冷杉種群的遺傳多樣性，旨在了解該種群在分佈區內的遺傳變異水平和遺傳結構情況；研究結果將有助於更清楚地認識這一瀕危類群的生存潛力和瀕危程度，而且可以為制定何種挽救和保護措施提供科學的依據。Abies yuanbaoshanensis having survived the quaternary period ice - age is significant not only to studying the occurrence and evolution of the chinese ancient south plant flora but also to the ancient climate and geography. especially, it has the scientific value of inquiring into the climate of the quaternary period ice - age and is called live fossil because it could provide the basis for studying the climatic change and the changes of plant
元寶山冷杉是第四紀冰期倖存下來的瀕危物種，在廣西的發現，對于研究我國南方古代植物區系的發生和演變，以及古氣候、古地理有重要意義，特別是對第四紀冰期氣候的探討有學術價值，它是研究氣候變化和植物變遷的依據，是活化石。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。In los angeles on thursday, beijing mayor wang qishan reminded business leaders who may have been to shanghai and beijing that the masses of rural poor in china earn less than half the $ 4, 557 of an urban beijing dweller
應亞洲協會邀請，上周前往洛杉磯發表演講的北京市長王歧山，也不忘提醒洛杉磯商界，雖然北京市人均收入已達四五五七美元，但別忘了廣大的農村地區，農民的年收入還不到北京的一半呢。分享友人
