초록

본 연구는 서양톱풀 Achillea millefolium의 품종에서 개화특성에 미치는 몇 가지 생장조절제의 영향을 규명하여 서양톱풀의 분화재배 시 관상 가치를 높일 수 있도록 분화용 서양톱풀의 개화에 미치는 적정 생장조절제 농도를 찾고자 신장기 직전에 2회 살포하였다. 초장은 ethephon 1,000ppm에서 45.7 cm로 가장 길게 나타났고 uniconazole은 20ppm에서 11.1cm로 초장의 억제 효과가 컸다. 소화수는 대조구에 비해서 ethephon 200 ppm에서는 오히려 47.8% 증가하였으나 paclobutrazol 200 ppm에서는 43.6%로 적었고 uniconazole 20 ppm의 농도에서는 90.0%나 감소한 것으로 나타났다. 측화수도 ethephon에서 28.6%, paclobutrazol에서 23.5% 증가하여 많아졌으나 uniconazole에서는 55.3%나 감소하였다. 결과적으로 ethephon에서는 초장과 개화수가 증가하였고 uniconazol에서는 초장이 작아졌으나 개화가 지연되고, 개화수가 유의하게 적어졌다.

The purpose of this study was to investigate the effects of ethephon, paclobutrazol, and uniconazole on the flowering of potted Yarrow (Archillea millefolium). Each plant growth regulator was sprayed two times before stem elongation period of yarrow. The tallest was 45.7 cm at $1000mg{\cdot}L^{-1}$ ethephon and the shortest was 11.1 cm at 20 uniconazole. Uniconazole delayed flowering and decreased the number of flowers. Both uniconazole at 20 ppm and paclobutrazol at 200 ppm decreased the number of florets to 90.0% and 43.6% of control, respectively. In ethephon, number of florets was increased 34.1% compared with control. In addition, ethephon and paclobutrazol increased the number of mean auxillaly flowers to 28.6% and 23.5% of control, respectively. On the other hand, uniconazole decrease the number of auxillary flowers to 55.3%. Thus, paclobutrazol was recommended as a suitable plant growth regulator for yarrow pot plant production.
