摘要: 苦瓜種子子葉小,種皮厚,厚及硬之種皮限制其發芽。本試驗利用種子前處理之方法促進種子發芽,提升苦瓜種子之品質。以'青皮'品種之苦瓜種子為試驗材料。掐開於胚根處之部分種皮並以流水浸種12小時,於30、25、20°C可得到最佳的發芽率。種子以50°C溫水浸種1小時較40或60°C及不同時問處理者有顯著較佳之發芽率。種子以濃硫酸浸漬處理30秒發芽率最高,但浸漬時間超過30秒發芽率則下降。將掐開種子以15%雙氧水浸種25分及未掐開種子以1%雙氧水為種子第一次之發芽水處理有較高之發芽率。利用種子、蛭石2號及0.1%NaOCl之混合,比例為9:12:18(重量百分比),滲調l天,種子發芽速度最快。以掐開種皮流水浸種12小時或不掐開種皮以50°C溫湯浸種1小時,可提高種子萌芽率。
Bitter gourd seeds have small cotyledons enclosed in a hard, thick seed coat. A number of pre-sowing treatments can increase germination by overcoming the limitations imposed by the seed coat. Clipped and soaked in running water for 12 hrs could enhance bitter gourd seed germination at 30, 25 and 20∘C. Seed immersed in 50∘C water for 60 min exhibited significantly higher germination than seeds immersed at other temperatures and for different times. The germination of seeds treated with H2SO4 was the highest after 30 sec of immersion. Germination was higher for clipped seed immersed in 15﹪H2O2 for 25 min and for unclipped seeds imbibed with 1﹪H2O2 water .Priming seeds for one day with vermiculite No.2 and NaOCl at a seeds: vermiculite #2 : 0.1%NaOCl ratio of 9:12:18, by weight produced the highest germination rate. The highest emergence rate was achieved with two different treatments of soaking clipped seeds in running water for 12 hr or immersing unclipped seeds in 50∘C water for 1 hr. The pre-sowing treatment that increased germination were seeds immersed in 50∘C water for 60 min or clipped and soaked in running water for 12 hrs.
