Abstract

Elsholtzia byeonsanensis is a Korean native plant of the Lamiaceae family, and was first introduced in the Korean Journal of Plant Taxonomy. This plant has a short plant length of 20-35 cm, with leathery and glossy leaves. The purple flowers bloom in November, so they are highly useful as potted or ground cover ornamental plants. In this study, tray cell size (128, 162, and 200-cell trays), soil composition [horticultural soil (HS): decomposed granite (DG) 1:1, 1:2, and 1:4 (v:v)], seeding rate (1, 2, and 3 seeds per cell) and additional fertilizer concentrations (0, 250, 500, and 1000 mg/L Hyponex) were tested to find out the optimum seedling growth conditions. As a result of the study, E. byeonsanensis growth increased proportionally as the cell size of the tray increased. The growth was inhibited as the percentage of DG increased. As for the growth according to the seeding rate, plant height, plant width, leaf length, and leaf width decreased as the seeding rate increased, but there was no difference in the number of leaves, stem diameter, and root length. There was an increasing trend in seedling growth as the additional fertilizer concentration increased. Therefore, for producing E. byeonsanensis seedling, it is most effective to fill HS or HS:DG 1:1 in 128-cell trays, sow one seed per cell, and spray the seedling at 1000 mg/L for additional fertilizer.

변산향유는 꿀풀과의 국내 자생식물로 식물분류학회지에 처음으로 알려졌다. 초장은 20-35 cm로 작고 잎은 혁질로 윤택이 있다. 꽃은 11월에 보라색으로 개화하는 특징을 갖고 있어 분화 및 지피용 관상소재로 활용도가 매우 높다. 따라서 본 연구는 관상식물로 활용하기 위해 변산향유의 육묘 시 플러그 트레이 종류(128, 162, 200구), 토양조성(원예상토: 마사 1:1, 2:1, 4:1), 파종 립수(1, 2, 3립) 및 추비 농도(0, 250, 500, 1000 mg/L)의 수준을 구명하기 위해 수행하였다. 연구의 결과 변산향유는 트레이의 셀 크기가 커질수록 생육도 비례하여 증가하였다. 토양조성에 따른 생육은 마사토의 비율이 증가할수록 생육이 억제되었다. 셀 당 파종량에 따른 생육은 파종량이 많아질수록 초장, 초폭, 엽장, 엽폭이 감소하였으나 개체당 엽수, 줄기직경, 근장은 큰 차이가 없었다. 추비농도별 처리는 농도가 높아질수록 생육도 증가하는 경향을 보였다. 따라서 변산향유는 육묘시 128구 트레이에 원예상토를 충진한 다음 셀 당 1립 파종하여 재배하며, 추비는 비교적 고농도인 1000 mg/L로 엽면살포하여 육묘하는 것이 가장 효과적일 것으로 판단된다.
