蘭嶼產瀕危植物腰果楠之微體繁殖

Abstract

腰果楠為產於蘭嶼的瀕危植物，本研究利用一年生種子苗的頂芽及含節莖段在1/2 MS添加2.5 mg/L BA及0.5 mg/L NAA兩星期可誘導芽體產生，產生芽體的莖段先在添加0.5 mg/L BA及0.15 mg/L NAA的WPM基礎培養基四至六週，再加入添加0.5 mg/L BA及0.3 mg/L NAA液體培養基雙層培養六週，可促進芽體抽長，再移至添加0.5 mg/L BA及0.1 mg/L NAA的WPM基礎培養基可促進發根，最終移入不含生長調節劑的WPM培養基一年，植株長至5-8 cm移至瓶外

Dehaasia incrassate (Jacks) Kosterm. (Lauraceae) is an endangerd tree species of the Orchid Island, located in the southeast of Taiwan. The shoot tips and nodal segments derived from 1-yr-old seedling were induced for bud sprouting in MS semi-solid medium
