中文摘要 | 本研究針對15個山藥品種系之植株及塊莖特性、不同海拔對其塊莖性狀與產量之影響、以及其塊莖內五種抗氧化酵素活性之差異,進行調查、分析、探討與評估,同時為開發多元化山藥優良品種系,進行四種不同類別山藥塊莖性狀與產量之比較試驗,所得結果可供選育兼具生產與抗氧化潛力之山藥優良品種系,及供進一步栽培、加工與醫藥利用之參考。由多元化山藥優良品種系之開發結果顯示,中型山藥類中特三品系(70W06)、特七品系(70W17)、特11品系(70W08)、大葉壽豐品系(70W42)、J07品系(70W72)及泰雅品系(83CM121)之表現優異;長型山藥類中基隆大葉品系(70W75)、北投品系(70W48)、陽明品系(70W70)及F155品系(70W73)之塊莖產量表現可高達50 t/ha以上;紅肉山藥類中除紫玉血薯品系(70R16)及名間長紅品系(70R20)之產量可達40 t/ha以上外,其餘僅埔一品系(70R01)、松柏長紅品系(70R22)及紅毛薯(83CM302)之塊莖產量有30 t/ha以上之潛力。由不同海拔試區對山藥塊莖性狀與產量之比較結果可知,六處試區中名間試區之平均產量可達45 t/ha,較羅娜與尖石二試區高達2倍以上;參試山藥中二刺品系(代號70W47)、臺農1號(TNG1)、臺農2號(TNG2)、汕二品系(70W34)、汕三品系(70W35)及中國長品系(80W02)等之塊莖產量皆有達40 t/ha以上之記錄。由15個不同山藥塊莖內抗氧化酵素之活性比較結果可知,汕三品系塊莖中PO、PPO、SOD及CAT等抗氧化酵素之活性頗高,汕二品系在PO、PPO及SOD,臺農2號在PO、SOD及GR,以及二刺品系在PPO、SOD及CAT等三酵素有較高活性,70W47之SOD活性尤其明顯高過其他參試品種系。綜合比較15個山藥之生產潛力與SOD酵素活性顯示,70W47、70W35、70W34、TNG2及F155品系(70W73)等之表現最優異。 |
英文摘要 | A part or total of 15 Dioscorea genotypes had been cultivated, analyzed, and evaluated at six counties in Taiwan in 1998. The results obtained from comparison test on the plant growth characteristics and yield potential of these Dioscorea plants indicated that 70W47, TNG1 TNG2, 70W34, 70W35, and 80W02 might be the most promising lines due to their high yield potential over 40 t/ha. Besides, the following Dioscorea genotypes could also be recommended as superior yam lines, such as 70W06, 70W17, 70W08, 70W42, 70W72, 83CM121, 70W75, 70W48, 70W70, 70W73, 70R22, 83CM302, 70R16 and 70R20. Experimental data also indicated that 70W35 had high enzyme activity of peroxidase (PO), polyphenol oxidase (PPO). superoxide dismutase (SOD) and catalase (CAT), 70W34 had high activity of PO, PPO and SOD, TNG2 had high activity of PO, SOD and glutathione reductase (GR), and 70W47 had high activity of PPO, SOD and GR. The activity of SOD expressed by 70W47 is particularly higher than other genotypes. The results suggested that the following five yam lines, i.e. 70W35, 70W34, TNG2, 70W47 and 70W73, which possessed both properties of high yield potential and high SOD enzyme activity, could be developed for wider and further purposes. |
