摘要

台灣藜(Chenopodium formosana Koidz)屬莧科雙子葉植物，多分布於台東與屏東地區，且為原住民作為釀酒、祭祀用作物。台灣藜品系多且色彩繽紛，具有觀賞價值，但目前尚未瞭解不同顏色台灣藜農藝性狀間之差異，及性狀的變化對產量之影響。本研究調查橘色、橘紅色、紅色與紅紫色四種不同顏色台灣藜之株高、葉片數、分枝數及莖粗等農藝性狀。試驗中發現，橘紅色台灣藜在各性狀調查表現較高，分別為株高273公分、葉片數50片、分枝數48支與莖粗29公釐，且單株穀粒重也是以橘紅色台灣藜73公克為最高。由本試驗結果得知，臺灣藜生長發育時之農藝性狀會影響穀粒產量，其中以橘紅色台灣藜產量最高。

Taiwanese quinoa (Chenopodium formosanum Koidz., also known as djulis) belongs to the Amaranthaceae family. It is distributed in the Taitung and Pingtung areas and was previously used for worship by Taiwan aboriginal tribes. Djulis has different lines with colorful and ornamental value. Currently, the impact of changes in the differences between the colors of djulis on agronomic traits and grain yield is not understood. This study investigated the influence of the height, number of leaves and branches, and stem diameter on the agronomic traits of orange, orange- red, red, and purple- red djulis. The results indicate that the performance traits of the orange- red djulis were the highest. These traits were as follows: a height of 273 cm, 50 leaves, 48 branches, and a stem diameter of 29 mm. Furthermore, the grain weight per plant of 73 g in the red- orange djulis was the highest. In conclusion, the agronomic traits and development of djulis affect grain yield, and the red- orange djulis had the highest yield among the four investigated colors of djulis.
