摘要

本實驗比較孤挺花在田間以及溫室內不同環境條件下的生長。孤挺花4品種的母球切割成瓣狀鱗片後，誘導形成小球。母球切割後6.5個月可得到周徑6- 10cm的小球。4品種的小球分成兩組，一組小球種植於田間、另一組小球種植於溫室內。種植10個月後，比較生長在田間與溫室內植株的葉片、鱗莖以及花的生長表現。在葉片數、鱗莖的乾物重以及開花表現方面，田間與溫室內兩者之間無顯著差異。然而，在田間生長的鱗莖周徑較大、且鱗莖上的小球數也較多。由本實驗可知，在戶外田間環境條件下的孤挺花鱗莖生長速度優於溫室內，從母球的切割開始，在18個月的期間可得到周徑26-37cm的鱗莖。

A study was conducted to compare the bulb growth rate of amaryllis (Hippeastrum hybridum hort.) grown in field and greenhouse. The mother bulbs of four cultivars were sliced into chips for bulblet formation and the bulblets were grown for 6.5 months until they were 6-10 cm in circumference. Then bulblets of these four cultivars were divided into two groups. One group was planted in open field and the other group was planted in a greenhouse. After ten months, the bulbs grown in the two environments were compared in terms of the growth of leaves and bulbs, and the flowering of bulbs. There were no differences between the bulbs grown in the two environments in their leaves numbers, percentage of dry matter of bulbs, and flowering. However, the bulbs grown in open field had a larger bulb circumference, more number of bigger daughter bulbs than those grown in greenhouse. This study showed that bulbs grown in open field grow faster than those in greenhouse, and could reach a circumference of 26-37 cm in 18 months from the mother bulb cut.
