摘要

本試驗目的在探討貯藏溫度、貯藏方法及貯藏期對薑荷花種球萌芽出土率之影響。以根莖直徑1.5－2.0cm帶2－3個貯藏根的種球為材料，用濕藏法（層積在含水率85%濕泥炭土中）與乾藏法（層積於含水率58%剛開封的泥炭土中）二種包裝方法，分別放在10℃或15℃下冷藏，經2個月及4個月後取出種植，比較種球之萌芽出土率。試驗結果顯示，10℃濕藏2個月後種球萌芽出土率為83.3%，4個月後萌芽出土率降為61.7%。15℃濕藏2個月及4個月，種球萌芽出土率分別為88.3%及65%。10℃乾藏2個月及4個月者，種球萌芽出土率均為83.3%；而15℃乾藏2個月及4個月，種球種植後之萌芽出土率分別為91.7%及90%。由本試驗結果推薦，薑荷花種球之貯藏以15℃乾藏為宜。

Curcuma alismatifolia is a new tropical cut flower crop which is becoming a favorite on the summer market in Taiwan. Curcuma rhizomes of 1.5-2.0cm in diameter and bearing 2-3 storage roots were used in this study to explore the storage condition and duration. The results showed that after storage in wet peat moss (contained 85% of water) for 2 months at 10℃ the emergence of shoots was 83.3%, while after 4 months storage the emergence decreased to 61.7%. The emergence of shoots was 83.3% and 65% when stored in wet peat moss at 15℃ for 2 and 4 months, respectively. Compared with storage in wet peat moss, rhizomes stored in dry peat moss (contained 58% of water) had higher emergence rate. After storage in dry peat moss for both 2 and 4 months at 10℃, the emergence maintained 83.3%. However, after storage at 15℃ for 2 and 4 months in dry peat moss the emergence of shoots were 91.7% and 90%, respectively. Therefor, we recommend that Curcuma rhizomes be stored in dry peat moss at 15℃.
