中文摘要 | 本研究以蒐集自台灣三個地區之31個大果油茶收集系及五個地區之46個小果油茶收集系為材料,共以77個油茶收集系進行葉部性狀變異之評估。研究結果顯示,經由葉長、葉寬、長寬比、葉厚、鋸齒數、內折度及反轉度等七個數量性狀的主成分向量分析,可清楚的將大果油茶及小果油茶分群;以多變數判別分析方法所建立之大果油茶和小果油茶判別公式,亦具有極高的判別度,顯示葉部性狀可應用於鑑別大果油茶與小果油茶。葉長、葉寬、葉厚、長寬比及鋸齒數等五個性狀為穩定性較佳的數量性狀,其平均變異係數(CV)皆在10%左右,未來建立品種性狀檢定表應可考慮將此五個性狀納入調查項目,作為品種間鑑別的參考依據。 |
英文摘要 | Oiltea camellia is an important and unique traditional oil crop of the genus Camellia in Taiwan and southeast China. The variation in leaf characters for 31 Camellia oleifera accessions (collected from 3 areas) and 46 Camellia tenuifolia accessions (collected from 5 different areas) in Taiwan was evaluated. Based on seven leaf traits, including leaf length, leaf width, leaf thickness, leaf ratio, numbers of serrations, percentage of difference between the actual length of the leaf and the natural ones and percentage of difference between the actual width of the leaf and the natural ones, the result of principle component analysis could clearly distinguish C. oleifera and C. tenuifolia. The formula established by multivariate discriminate analysis was very powerful and reliable in distinguishing the two oiltea Camellia species. The coefficients of variation (CV) of leaf length, leaf width, leaf thickness, leaf ratio and numbers of serrations were around 10%, suggesting satisfactory stability of the traits. These traits could be catalogued and used for variety identification. |
