병풍쌈(Cacalia firma)은 병풍취라고도 하며 초롱꽃목 국화과에 속하는 다년생 식물로 한국, 중국, 일본에 분포되어있다. 웰빙 삶을 위한 생활식습관의 변화에 따라 기능성 식품과 유기농 채소에 대한 소비자의 요구가 증가하고 있다. 본 연구는 병풍쌈 임간재배를 위한 적정 광조건을 구명하기 위해 1년생 병풍쌈에 대해 차광망을 이용하여4가지 광조건 25%, 55%, 75%와 95% 차광처리(전광의 50%, 30%, 20%, 10% 상대광도)와 대조구(전광)에서 생육 후초기 생장과 생리적 반응을 조사·분석하였다. 75% 차광처리구는 대조구와 비슷한 초장, 뿌리생육과 함수율을 보였으나, 잎의 길이, 폭과 면적이 증가하여 엽 건중량과 총 건중량이 증가하였다. 특히 95% 차광처리구에서는 대조구에 비해 근원경과 뿌리길이는 감소하였으며 총 건중량도 감소하였으나, 초장이 약 40% 증가 하였으며 엽 생육과 함수량 또한 증가하였다. 엽면적비(specific leaf area; SLA)와 엽면적률(leaf area ratio; LAR)은 통계적 유의성을 보이며 대조구에 비해 매우 높게 나타나 잎의 두께가 얇고 수광면적이 큰 것으로 나타났다. 이와 같이 병풍쌈은 낮은 광조건에서도 원활한 탄소동화작용을 하고 있는 것으로 나타났다. 본 연구 결과 병풍쌈의 임간재배를 통한 적정 광요구는차광처리 75~95%(상대광도 10~20%)로 조사되었으며, 산채류로써의 상품성을 고려할 때 임간지역에서 75% 이상 차광재배 함으로써 식감과 생산량을 높일 수 있을 것으로 기대된다. 이 연구결과는 병풍쌈의 임간재배 가능성을 위한 기초자료로 활용할 수 있을 것으로 판단된다. Cacalia firma is a perennial plant in Asteraceae, Parasenecio that distributed in Korea, China, and Japan. As dietary style changes for well-being life, consumer`s demand of functional food and organic vegetables is getting increased. This study was conducted to investigate the optimum light conditions of P. firmus in forest farming. One year old seedlings were grown under four different light conditions 10%, 20%, 30%, and 50% of sunlight by shading (equals50%, 30%, 20%, and 10% relative brightness respectively) and non-treated control under full sunlight. They were analyzed for early growth and physiological response. Seedlings grown under 75% shading showed similar height, root growth, and leaf water content to control. However, their leaf length, width, and total leaf area were increased, which caused increased leaf dry weight and total dry weight. Especially, seedlings under 95% shading showed 40% increase in height and more leaf growth and leaf water content, although they had shorter main root length and root collar diameter than control. In addition specific leaf area (SLA) and leaf area ratio (LAR) were higher than control and indicated that they were statistically significant difference from control. Higher SLA refers thinner leaf thickness, higher LAR means larger leaf area. The results indicate seedlings under 95% shading have higher water content, thinner leaf, and wider lightinterceptionareas. It is plausible that P. firmus is active in chlorophyll activities and carbon dioxide assimilation at even lower light conditions. These results suggest that the optimum light level of P. firmus for artificial cultivation in forest farming ranges from 75~95% shading (20%-10% of relative brightness). When salability as ‘sanchae’ (wild edible greens)is considered, P. firmus could be cultivated under 75% shading in forest farming and expected to have better taste andhigher yield. We suggest these results as basic data of P. firmus for possible forest farming.

본 연구는 최근 수요가 급격히 증가한 우산고로쇠의 유묘 생육 시 차광수준에 따른 우산고로 쇠 용기묘의 생장 특성을 구명하고자 하였으며, 우산고로쇠 용기묘의 생산을 위한 기초자료로 활용되고자하였다. 실험은 묘포장 내 차광수준(전광 및 25%, 55%, 75%, 95% 차광)을 달리하여 설치된 차광시설에서 실시되었다. 수고와 근원직경은 전광에서 각각 233.7cm와 21.85mm로 가장 높게 조사되었으며, 근원직경의 경우에는 차광수준이 높아질수록 낮아지는 경향을 보였다. 잎, 줄기, 뿌리 및 전체의 건중량은 모두 전광에서 가장 높은 것으로 조사되었으며, 이것은 수고와 근원직경 생장이 전광에서 높게 나타난 결과와 부합된다. T/R율은 전체적으로 1.3∼2.3의 범위로 조사되었으며 상대적으로 좋은 생장을 보인 전광에서는 2.1로 나타났다. 묘목품질지수인 QI(Quality index)는 전광에서 가장 높은 값으로 나타났으며 차광률이 높아질수록 낮아지는 경향을 보였다. 본 연구결과를 종합하면, 우산고로쇠를 보다 건전한 용기묘로 생산하기 위해서는 전광에서 생육하는 것이 좋을 것으로 판단된다. This study was carried out to investigate on growth characteristics of Acer okamotoanum container seedling by shading level. The experiment was performed by shading treatment (full sunlight, 25%, 55%, 75% and 95% shading) in nursery. Height and root collar diameter were surveyed to be the highest 233.7cm and 21.85mm separately in full sunlight. Root collar diameter was getting lower in the higher shading level. Leaves, shoot, root and total dry weight were surveyed to be the highest in full sunlight and the same as surveyed value of height and root collar diameter. T/R ratio was surveyed with 2.1 in full sunlight (overall 1.3∼ 2.3). Quality Index (QI) was the highest in full sunlight and the higher shading level, the lower QI. As a result of surveying the whole experiment, Acer okamotoanum grows well in full sunlight.

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.

Background: This study investigated the effect of soil properties and soil bacterial community on early growth characteristics of wild-simulated ginseng (Panax ginseng C. A. Meyer) in coniferous and mixed forest experimental fields. Methods and Results: The soil bacterial community was analyzed using a high throughput sequencing technique (Illumina MiSeq sequencing). The relationship between the soil bacterial community, soil properties, and growth characteristics of wild-simulated ginseng were analyzed using principal coordinate analysis (PCoA) and the Pearson’s correlation analysis. Soil properties and soil bacterial community showed significant difference with forest physiognomy. Results of Pearson’s correlation analysis and PCoA showed that the soil properties (soil pH, organic matter, total nitrogen, and cation exchange capacity) and soil bacterial community had significant correlation with tree species ratio and early growth characteristics of wild-simulated ginseng. Conclusions: This study clearly demonstrated the effect of soil properties and soil bacterial community on early growth characteristics of wild-simulated ginseng in coniferous and mixed forest. Moreover, these results will help in the selection of suitable cultivation sites for wild-simulated ginseng.
