中文摘要 | 葉菜甘藷係一種生長快速,營養價值極高,且全年皆可栽培之深綠色健康蔬菜。 本試驗利用葉菜甘藷品種桃園2號及甕菜種,探討不同季節及每日上下午採收是否影響品質 變化。試驗結果顯示鮮重、乾重、可溶性糖類、維他命C、及葉片硝酸鹽含量以春夏季節較 秋冬為高。澱粉、可溶性蛋白質及草酸含量則以冬季較高。中洗纖維春季較低,酸洗纖維各 季節相似。整體言之,採摘季節影響食用品質,而各食用品質在各季節表現並不一致,每日 採摘時間表現食用品質差異可能受日照及溫度變化之影響。 |
英文摘要 | Highly nutrient value of dark green leafy sweet potato is considered the healthy vegetables. It can grow rapidly to cultivate all the year round in Taiwan. Two cultivars (Taoyung 2 and Ong tsai) were used to investigate the variation of eating quality in different seasonal and diural harvesting times. It indicated that the sweet potato leaf tips in spring and summer seasons had higher fresh weight, dry weight, soluble sugar content, vitamin C content and nitrate content than the fall and winter seasons. High value of starch content, soluble protein content and oxalic acid content were appeared in winter season. The neutral detergent fiber content was low in spring season, whereas the acid detergent fiber content was similar in different seasons. However, the harvesting seasons and diural harvesting times of leafy sweet potato would influence the components of eating quality inconsistently which might cause by the change of temperature and daylingt. |
