不同生長條件對台灣藜幼苗機能性成分之影響
Effect of growth condition on functional components of djulis (Chenopodium formosanum Koidz.) sprout
摘要
台灣藜(Chenopodium formosanum Koidz.)為台灣原生作物，具有豐富的營養價值及高機能性成分，其抗氧化能力十分優秀，對於預防人類慢性疾病發生極具潛力。惟大多數人幾乎只食用種子的部分，多項研究指出種子發芽後其機能性成分及抗氧化能力會大幅增加。本試驗依序從溫度(18℃、24℃℃及30℃)、種植天數(1~7天)及鹽份逆境處理 (50、100、150及200 mM)三個試驗，探討不同環境因子對於台灣藜幼苗機能性成分及抗氧化能力之影響。結果顯示台灣藜幼苗在高溫下，次級代謝物含量最高；低溫時其抗氧化潛力最大，且發現台灣藜幼苗保健功效與總酚含量為正相關。在種植5-6天時，具有最高的次級代謝物含量及抗氧化能力，所有機能性成分皆與抗氧化能力相關。鹽分逆境試驗結果顯示適度的鹽分濃度可有效增加作物生理表現、機能性成分含量及抗氧化能力。

Djulis (Chenopodium formosanum Koidz.) is an native crop in Taiwan. It contains richness nutritional contents and functional components. It has great antioxidant activity. However, most people just eat seed. Studies show that seed germination induce its functional components and antioxidant activity, which means more effective. The object of this study is to investigate the effects of temperature, seeding days and salt stress treatment on djulis functional components and antioxidants capacities. The study is divided into three parts. First of all, growth temperature treatment with 18, 24 and 30℃. Secondly, seeding days, which ranges from 1-7 days. The final treatment is salt stress, with four concentrations (50, 100, 150 and 200 mM). Results revealed that djulis sprouts in high temperature (30℃) had the highest amounts of secondary metabolites and in low temperature (18℃) had the highest antioxidant capacities. The antioxidants capacities of djulis sprouts in temperature treatment might be constituted by phenolic compound due to significant positive correlation. When seeding days was up to fifth or sixth days, the sprouts turned out to have the highest functional components and antioxidant capacities. At that time, all of the functional components were correlated to djulis sprouts' antioxidant capacities. The salt stress treatment revealed that moderate salinity could increase physiological performance, the amounts of functional components and antioxidants capacities.
