본 연구는 기능성 산채로서 수요가 확대되고 있는 곰취를 대상으로 차광처리가 반음지식물인 곰취 유묘의 초기 생장에 어떠한 영향을 미치는지 알아보고자 실시하였다. 실험은 차광수준(전광 및 35, 50, 75, 95% 차광)을 달리하여 실시하였으며, 차광별 생장과 형태적 특성을 각각 조사하였다. 실험 결과, 곰취의 초장은 75%차광에서 17.3cm, 근원직경은 전광에서 2.13mm로 가장 높은 생장을 보인 것으로 조사되었다. 부위별(잎, 줄기, 뿌리) 및 전체 생중량은 모두 50% 차광에서 각각 1.784g, 1.330g, 0.791g, 3.905g으로 가장 높은 것으로 조사되었다. 건중량의 경우, 지상부(잎, 줄기)와 전체 건 중량은 35% 차광에서, 뿌리는 전광에서 가장 높게 나타났다. 엽면적은 50% 차광에서 39.3cm2로 가장 높게 조사되었으며, SLA와 LAR은 차광 처리구에서 차광률이 높아질수록 증가하였다. 엽두께는 차광률이 높아질수록 얇아지는 경향을 보였다. 뿌리 특성에서는 95% 차광을 제외하고 전반적으로 좋은 생장을 보였으나 상대적으로 35∼75% 차광에서 세근발달이 더 좋은 것으로 나타났다. 본 실험 결과를 종합적으로 살펴보면, 곰취는 높은 광도로 인한 피해를 입은 전광과 저조한 생장을 보인 95% 차광을 제외한 35%∼75% 차광에서 상대적으로 좋은 유묘 생산이 가능할 것으로 판단된다. This study was carried out surveys on early growth characteristics of Ligularia fischeri, plants of half-shaded grounds, primarily used as functional wild edible greens. The shading treatment was regulated with the shading level (full sunlight, 35%, 50%, 75%, and 95% of full sunlight). According to the experiment, the height was the highest under 75% of shading (17.3cm), and root collar diameter was the highest under full sunlight (2.13mm). It was found that fresh weight (leaf, shoot, root and whole) was the highest (1.784g, 1.330g, 0.791g, 3.905g respectively) under 50% of shading. In case of dry weight, leaf, shoot and whole dry weight were surveyed the highest under 35% of shading, and root dry weight was the highest under full sunlight. Leaf area was the highest under 50% of shading (39.3cm2) and the higher shading level, the higher SLA and LAR. It was surveyed that the higher shading level, the thinner leaf thickness. In case of root characteristics, it was showed that the relatively high height growth under 35%∼75% of shading, excepting 95% of shading. As a result of surveying the whole experiment, if the early growth of L. fischeri is performed under 35%∼75% of shading, excepting full sunlight and 95% of shading, it would be more productive.

This study was carried out to determine the effects of shading and leaf mold treatment on growth characteristics and photosynthesis responses of Peucedanum japonicum in forest farming. It is very valuable as a sort of health food, so that the demand for the vegetable has increased recently. The experiment can not only increase the yield but also contribute to the development of eco-friendly technology for high-quality P. japonicum. It was performed by shading treatments (full sunlight, 35%, 50% and 75% shading) and leaf mold treatments (control, pine tree and chestnut tree). Height, stem diameter, root collar diameter, number of stem and dry weight were the highest in chestnut-leaf mold under full sunlight. Leaf area, leaf length and leaf width were the highest in chestnut-leaf mold under 35% shading. Photosynthetic rate, conductance to H2O, transpiration rate and water use efficiency were the highest in chestnut-leaf mold under full sunlight. Specially, photosynthetic rate was higher under chestnut-leaf mold in all shading treatment, and getting lower in the higher shading rate. As a result of surveying the whole experiment, it is concluded that P. japonicum grows nicely by maintaining 35% shading under chestnutleaf mold in forest farming. Thus, it is the most effective way to increase the yield for high-quality P. japonicum with eco-friendly technology.

본 연구는 대체에너지, 생태복원 및 밀원식물용 등으로 이용되어 묘목 수요가 증가되고 있는 쉬나무(Tetradium daniellii (Benn.) T. G. Hartley)의 우량한 용기묘 생산을 위한 적정 용기 규격(생육밀도, 용적 등)을 구명하고자 실시하였다. 적정 용기 구명 실험은 쉬나무를 임업시설양묘용 플라스틱 용기 5종(500 ml, 350 ml, 320 ml, 300 ml, 250 ml)을 사용하여 실시하였다. 실험결과, 간장과 근원경 생장은 SI 350 용기에서 현저히 높은 값을 보였으며, 대체적으로 용기 구 용적이 크고 생육밀도가 낮을수록 높은 생장을 나타냈다. 묘목의 뿌리형태특성을 측정한 결과 SI 350 용기에서 뿌리발달이 가장 왕성하게 조사되었다. 건물생산량도 SI 350에서 가장 높았고 전체적으로 간장 및 근원경 생장 결과와 유사한 경향으로 나타났다. 묘목의 품질을 나타내는 지수인 QI(Quality Index)도 SI 350 용기에서 0.97로 가장 높게 조사되었다. 연구결과를 종합하면, 쉬나무 용기묘의 우량한 묘목생산을 위한 적정 용기 종류는 SI 350 용기로 판단된다. There is an increasing demand for Tetradium daniellii seedlings due to their uses as alternative energy, for ecological restoration, and as a honey plant. This study was conducted to determine the optimum container for superior seedling production of T. daniellii. Experiments were performed using five plastic container types (500, 350, 320, 300, and 250 ml) for forestry facility cultivation. The height and root collar diameter growth of T. daniellii seedlings were significantly high in the 350-ml container. High growth appeared primarily in the container with a larger cavity volume and lower growing density. Root development was most active in full sunlight. The maximum dry matter production was observed in the 350-ml container, which was similar to the results of height and root collar diameter growth. QI, an index showing the quality of a seedling, was maximum at 0.97 in the 350-ml container. In conclusion, the 350-ml container is optimum for superior seedling production of T. daniellii.
