摘要

本試驗之目的為探討不同栽培環境及不同生育日數對當歸產量與有效成分阿魏酸與藁本內酯含量之影響。當歸在花蓮縣5個不同地區之調查結果顯示：單株平均重量、單株平均根重、阿魏酸（Ferulic acid）含量及藁本內酯（Z-ligustilide）含量均以玉里地區最高；不同生育期對當歸之農藝性狀比較試驗，試驗結果顯示當歸在株高、全株重、根重及根徑等農藝性狀之表現以生育日數205天較佳；當歸之有效成分阿魏酸之含量亦以生育日數205天較高；當歸之有效成分藁本內酯則以生育日數160天較高；當歸的抗氧化能力以生育日數235天最高。生育日數205天時為當歸開始抽花之時期，此時期在根部外觀、產量及有效成分含量均較佳，因此，以開花之初期來作為根部收穫適期，可作為農民田間栽培收穫之參考。

The purpose of this research was to study the effects on the yield, quality and active ingredient in different cultivated areas and different growth days of Angelica acutiloba. The characteristics of A. acutiloba were measured and compared for five different cultivated areas of Hualien. In comparison of the average plant weight, root weight and root width for A. acutiloba, the highest value was found from the roots cultivated in Yi-li area. The highest content of active ingredient of ferulic acid and Z-liguistilide was also found from roots cultivated in Yi-li area. In comparison on the agronomic traits of the roots at different growth days, the growth days of 205 days had the highest value in plant height, root weight and root width. The roots at growth days of 205 days had the highest ferulic acid content in A. acutiloba, while roots of 160 days had the highest Z-liguistilide content in A. acutiloba. In addition, roots of 235 days had the highest anti-oxidant capacity in A. acutiloba. The roots morphology, yield, active ingredient content and quality are good at growth days of 205 days, and then is the blossom stage in A. acutiloba. Therefore, the initial blossom stage is the root harvest suitable time, it will be as the reference of field cultivation harvest in A. acutiloba for the farmers.
