中文摘要 | 藉由臺灣華南薯蕷種原8 個質量性狀及9 個數量性狀調查,以評估其種原遺傳變異。結果顯示,8 個質量性狀中以老葉顏色、幼葉顏色、莖蔓顏色及芽色性狀頻度分佈較均勻,可供遺傳變異評估及種原鑑定參考,輔以9 個數量性狀,以增加種原評估或鑑定效果。9 個數量性狀中莖部直徑及莖節間長度等2 個性狀適合作為辨識種原重要指標。以群聚分析評估華南薯蕷種原植株外表性狀遺傳歧異性,結果顯示地區族群相互重疊。本研究對臺灣華南薯蕷種原植株性狀進行調查,並建立其種原蒐集、評估及利用上重要資訊。 |
英文摘要 | By eight qualitative and nine quantitative traits investigated to assess its genetic variation of D. collettii Hook. f. in Taiwan. According to the distribution frequency, the qualitative traits of matured leaf color, young leaf color, stem color and bud color were in uniform. These traits are suitable for the assessment of genetic variation and species identification. The quantitative traits of stem diameter and internode length could be used as important indicators for species identification. Based on plant traits, the cluster analysis showed the overlapping distribution in regions for D. collettii Hook. f. In this paper, studies of D. collettii Hook. f. in Taiwan have been established, and such important information will be useful in germplasm collection, evaluation and application. |
