摘要

本試驗旨在探討層積及GA浸漬處理對金花石蒜種子發芽之影響。種子經5℃層積1、2、3個月，以不層積為對照組進行發芽試驗。種子分別浸漬不同GA濃度250、500、1000 ppm與處理時間1、2、3、4、8、24小時，以不浸漬GA為對照組進行發芽試驗。結果顯示，在不同層積時間方面，第一個發芽種子的時間、50％發芽日數、平均發芽日數均隨著層積時間增加而縮短，且處理間達顯著差異，其中以層積3個月者最快速與整齊，最終發芽率以層積2個月者97.3％最高，與對照組74.7％差異顯著。在浸漬不同GA濃度與處理時間方面，GA處理對金花石蒜種子發芽並無促進效果，亦不具有取代低溫之效果。

The experiment was conducted to investigate the influence of stratification and GA soaking on seed germination of Lycoris aurea. The treatments include 5°C stratification 0, 1, 2, 3 months, GA concentration 0, 250, 500, 1000 ppm and soaking time 1, 2, 3, 4, 8, 24 hours were used on seed germination of Lycoris aurea. The results showed that the first seed germination, time to reach 50% of germination and day of average germination of seeds stratified at 5°C for at least 1 month were significantly more rapid and uniform as compared to fresh seeds, indicating that the final germinated percentage had increased. Treatment of seeds with various GA concentration and soaking time were not increase the seed germination, then the result was not as good as that with 5°C stratification.
