摘要: 
'達豐'結球萵苣種子發芽適溫於15~20°C,種子於25℃下發芽為98%,當溫度超過30℃以上,種子發芽受抑制,種子於35°C下,則不發芽。光照對萵苣種子於適溫下發芽之影響不大,但在高溫下則會延長發芽天數。萵苣種子於35℃,以l0ppm Ethrel處理20小時,有80%發芽率,l0mM GA3處理6小時,有78.9%發茅率,100μM BA處理6小時,有31.9%之發芽率。以l0mM GA3+l0ppm Ethrel+l00μM BA處理後,萵苣種子於25℃下有l00%之發芽率,35℃下有87.8%之發芽率及86.7%之出土率,發芽整齊度及平均發芽天數提高l天。

The germination percentage of ‘MESA659' lettuce was 98% at 25℃. The seeds can not germination at 35℃. The seeds were treated by 10 mM GA3 + 10 ppm Ethrel + 100μM BA. The germination percentage and the emergence percentage 87.6%, respectively, at 35℃. The uniformity of germination and the mean germination days were shortened for one day.
