| 中文摘要 | 薑黃(Turmeric),學名"Curcuma longa" L.,為薑科薑黃屬植物,在工業與香料上是重要的經濟作物。本試驗以19個薑科作物及高雄市旗山區收集之20個薑黃收集系為材料,探討薑科植物及薑黃收集系間之遺傳變異性與親緣關係,其中以簡單序列重複區間(ISSR)分子標誌探討19個台灣薑科作物親緣關係時,發現19個薑科作物之遺傳相似性介於0.1-0.985之間。以ISSR資料經主作標(PCoA)分析法之三維立體圖,可將19個薑科劃分成6個類群,類群的分布結果顯示可用ISSR解析薑科作物之親緣關係,並可據此有效建立台灣薑科作物的生態庫與遺傳基因池。又在19個薑科分析中,6個不同來源之薑黃材料之ISSR分子標誌存在一定程度之變異,故進一步以高雄旗山區薑黃進行ISSR分子標誌分析。根據分析結果,旗山區薑黃遺傳相似性介於0.797-0.986,利用主座標分析(PCoA)圖可將20個薑黃收集系分成4類群,並以CNY12與其他收集系的相似性最低。本研究結果顯示,台灣薑黃作物可能因為受到環境壓力與人為選拔,造成DNA分子層次存在相當程度之變異。 |
| 英文摘要 | Turmeric ("Curcuma longa" L.) is a member of ginger family, Zingiberaceae, and has become an important economic crop for industrial uses and spice production. In this study, a total of 19 ginger species and 20 turmeric collected lines which were gathered from Cishan area, Kaohsiung, Taiwan, were subjected to assess the genetic diversity and phylogenentic relationship by using inter-simple sequence repeats (ISSR) markers. For the 19 ginger species, the genetic similarity was ranged from 0.1-0.985, and six distinct groups were clustered by the results of the principal co-ordinates analysis (PCoA) and dendrogram. For the 20 turmeric lines, the genetic similarity was ranged from 0.797 to 0.986, and four distinct groups were clustered by the results of PCoA and dendrogram. Moreover, six of the 19 ginger species exhibited some genetic diversity revealed by ISSR markers. Among these 20 collected lines, CNY12 was exhibited phylogenetically far-related to the other collected lines. The genetic relationships of Zingiberaceae plants constructed herein offered an effective establishment of an agro-climate and a gene pool library of "C. longa" L. in Taiwan. Despite exposure to environmental stresses and artificial selection for a long time, the vegetative propagation of Taiwanese turmeric existed genetic diversity at DNA molecular level. |
