摘要

本研究針對宮燈百合（Sandersonia aurantiaca Hook.）探討剪除花苞及摘心處理對宮燈百合種球生長和繁殖之影響。剪除花苞與否對植株之葉長與葉寬並無顯著影響，但花苞剪除後，採後種球重量達3g以上者達30.0%。不同節位摘心對宮燈百合種球生育之影響，結果以第10節間摘心之處理表現較佳，平均每球重5.2g，而未處理者平均每球重最低，為2.9g，故結果顯示摘心可促進種球肥大，上述相關試驗結果可供宮燈百合產業推廣之參考。

Removal of flower buds and terminal bud were conducted to evaluate the effectiveness of these treatments on tuber growth and propagation of sandersonia. There was no significant difference of the length and the width of leaf between removal of flower buds and control treatment. Harvested tubers which were over 3g while in treatment of removal of flower buds is 30.0％, that is high than control treatment. Therefore, removal of flower buds would increase tuber's weight. As regards removal of different pinch, the results showed that the average weight of tuber was 5.2g in the treatment of 10th internodes, while control group were 2.9g which were the lowest. It showed that, the removal of terminal buds could increase tuber weight. The experimental results of this study could be taken as reference for improving sandersonia industry in Taiwan.
