Abstract

Proper light intensity, potting media, fertilization level, and shade tolerance were investigated to develop Orostachys (Korean name, Nungyu bawisol) as a potted ornamental plant. The best plant growth was shown at 52% shading. Although plant growth decreased at 82% shading, ornamental value maintained at that shading rate, which indicate that O. 'Nungyu bawisol' has high shading tolerance. At over 90% shading, some of the plants died and showed decolorization and standing erect in leaves, resulting in a big decrease in ornamental value. Potting medium of decomposed granite (DG) : fertilizer-amended media (FAM) : river sand (RS) (6 : 2 : 2, v/v/v) showed the best growth in potted O. 'Nungyu bawisol'. Fresh weight of shoot part was 16 g in DG : FAM : RS (6 : 2 : 2, v/v/v), which was over 2 folds of those at the other medium. Drenching of Hyponex solution diluted by 1,000~2,000 folds 1 time per week brought the highest results in fresh weight, plant width, and runner number. Particularly, fresh weight of shoot part was 13 g higher than that of control (16 g). Leaf color tended to be darkened as concentration of Hyponex solution increased.

능유바위솔을 분화로 재배하고자 할 때, 적정 광도 와 내음성정도, 적정 분용토, 그리고 적정 시비조건을 알아보기 위해 실험을 수행하였다. 그 결과 능유바위솔은 52% 차광에서 생육이 가장 양호하였으며, 82% 차광까지는 생육이 감소하기는 하지만 상품성은 유지되어 내음성이 뛰어난 것으로 판단되었다. 90% 이상의 차광에서는 고사주가 발생하였으며, 엽색도 탈색되고 잎이 위로 서는 등 관상가치가 크게 저하되었다. 분용토로는 마사토 : 유비상토 : 강모래(6 : 2 : 2, v/v/v) 에서 생육이 가장 좋았다. 특히 지상부 생체중의 경우 다른 용토에서는 약 4~8g 범위였으나, 마사토 : 유비상토 :강모래(6 : 2 : 2, v/v/v)에서는 16g으로 2배 이상의 생육량을 보였다. 시비조건은 Hyponex 액비를 1,000~2,000배액으로 1회/주 처리했을 때, 생체중 및 초폭, 분지수 등에서 가장 좋게 나타났다. 특히 생체중의 경우 대조구(무처리)가 16g인데 비해 1,000배액 1회/주와 2,000배액 1회/주 처리에서 약 29g으로 80% 정도 생장량이 증가하였다. 엽색에서는 액비의 농도가 높을 수록 엽색이 짙어지는 경향이 보였다.
