Abstract:	黃花刺梨種子屬於硬實種子，不易吸收水分而無法正常發芽。本試驗以逆滲透水、25%雙氧水、96%硫酸浸泡處理，皆無法有效促進黃花刺梨種子發芽。種子經不同刻傷處理，以近胚處直線刻傷並使部分胚裸露處理，其發芽率最高達81.3%，種子平均發芽日數為6.9日，種子發芽率達50%之日數為7.4日。由結果可知，以近胚處直線刻傷處理可增加黃花刺梨種子之發芽率。 Due to Opuntia ficus-indica (L.) Miller is a kind of hard seed. The seed did not uptake water easily, and lead to the failed germination. Seeds could not be successfully germinated by soaking in reverse osmosis water, 25% hydrogen peroxide, and 96% sulfuric acid. After the treatments of scarifications, scarified in the straight line near embryo and made part of the embryo exposed. Their final germination rate approached to 81.3%. The mean germination time was 6.9 days, and the day of 50% germination rate was 7.4 days. The results have shown that the straight line scarification near embryo treatment and made part of the embryo exposed is promoting the seed germination of Opuntia ficus-indica (L.) Miller.
