摘要

臺闕一葉蘭的成熟種子，播於Knudson C培養基內含2g/ℓ活性砍。培養基中加入0.5~2.0mg/ℓ的菸鹼酸，均可促進原球體的生長及小苗鮮重，0.5mg/ℓ者可明顯促進葉之伸長，椰子汁能明顯地促進早期原球體及小苗之發育及鮮重，對小苗後期則影響不大，只10%的椰子汁能促進葉的伸長，5%及2%於小黃生長後期略有抑制作用。含25~100g/ℓ的香蕉泥對早期原球體及小苗之發育略有促進作用，但明顯地抑制小苗葉片之生長。

The niece of niacin, coconut milk and banana homogenates on seed germination and seedling growth of Pleione formosana were studied. It was shown chat Knudson C medium containing 0.5-20%wg/ℓ niacin or 5-20% (v/n) coconut milk enhanced the development and fresh weight of protocorm. However, only 0.5mg/ℓ niacin and 10% coconut milk could promote leaf growth in further development.
Banana homogenates could slightly promote protocorm development in the earely stage, while is strongly inhibited leaf growth and decreased fresh weight al seedling with increased concentration.
