Abstract

Primula sieboldi E. Morr., Primulaceae, is native to Korea, and has attractive plant characteristics when potted and used as bedding plants. This experiment was conducted to study on the dormancy breaking and seed germination. The weight of thousand seeds was 0.24 g. Seeds harvested in June did not germinate until March of the next year. Seed dormancy was broken by immersing in 800 $mg L^{-1}$ $GA_{3}$ solution for 24 hours. Germination speed was faster when 200 mM $KNO_3$ was added to $GA_{3}$ solution. Seeds were germinated in wide temperature range of 10-25$^{o}C$, with an optimal temperature range of 20-25$^{o}C$. Plant ceased to grow during the period of high temperature above 25$^{o}C$ in summer and low temperature below 10$^{o}C$ in winter. The level of abscisic acid (ABA) in root crown was 0.12 $\mu gg^{-1}$ fw, and ABA was detected only in December

분화 및 화단용으로 우수한 특성을 가진 한국자생 초본류 앵초의 화훼원예화를 위하여 종자의 휴면성과 타파방법 및 발아조건을 구명하고 식물체의 휴면성을 알아보고자 시험을 수행하였다. 앵초 종자는 6월 중순 성숙 후 휴면에 들어가는데, GA3 800mg·L-1용액에 24시간 침지함으로써 휴면이 타파되어 86.7%의 발아율을 보였고, GA3에 KNO3 200mM 첨가하였을 때 발아세가 향상되었다. 종자는 10-25oC에서 발아되었으나 적온은 20-25oC 범위였다. 식물체는 25oC 이상의 여름 고온기와 10oC 이하의 겨울 저온기에 지상부 생육이 정지되거나 휴면에 들어가는 현상을 보였다. 근권부의 ABA는 12월에 0.12mg·g-1FW이 함유되어 있었고 다른 시기에는 나타나지 않았다.
