This research was performed to investigate the effect of formaldehyde removal and confirm the utility of plants as indoor environment improvement systems. The plant materials used in this study were Fatsia japonica, Ardisia japonica, Ardisia pusilla and Davallia mariesii. Plants were placed in an airtight chamber under artificial formaldehyde. The initial formaldehyde concentration in the chamber was $500{\pm}30ppb$, and the conditions of $1,500{\sim}2,000lux$ light, $25{\pm}5^{\circ}C$ temperature and $80{\sim}90%$ humidity were maintained. Each chamber was treated as no plant, plant-only and Plant+soil. The total leaf number for Davallia mariesii, Ardisia japonica, Ardisia pusilla, and Fatsia japonica was 40.8, 48.6, 62.3, and 11.8 respectively. The total leaf space n of those plant materials were $2,385cm^2,\;1,252cm^2,\;2,468cm^2\;and\;1,262cm^2$ respectively. The formaldehyde concentration was reduced to $80{\sim}90%$ of the initial concentration in plant-only and Plant+Soil treatment chamber of all species in 12 hours. In the plant-only chamber, Fatsia japonica had removed formaldehyde density by 95% after 12 hours while Ardisia japonica had removed 90%. In the case of Ardisia pusilla, the early removal rate was higher in the plant-only treatment chamber than the Plant+Soil treatment chamber. The formaldehyde removal rate of Davallia mariesii was 98% after 12 hours. In the Plant+Soil treatment chamber, the amount of removal of formaldehyde per time of Davallia mariesii, Ardisia japonica, Ardisia pusilla, and Fatsia japonica was 20.42ppb/hr, 16.28ppb/hr, 2.5.42ppb/hr, 10.28ppb/hr respectively. In the plant-only, That was 22.50ppb/hr, 20.97ppb/hr, 20.83ppb/hr, 20.97ppb/hr respectively.

주진희,윤용한,Ju, Jin-Hee,Yoon, Yong-Han 한국조경학회 2012 韓國造景學會誌 Vol.40 No.2

본 연구는 유기질 비료와 멀칭재에 따른 리아트리스(Liatrisspicata)의 생육을 조사하여 무관수 옥상녹화에서의 효용성을 알아보고자 실시하였다. 4가지의 멀칭처리(무처리, 난석 멀칭, 바크 멀칭, 검은색 부직포 멀칭)와 3가지의 유기질 비료처리($A_1O_0$, $A_4O_1$, $A_1O_1$)로 총 12가지의 처리구를 옥상에 배치하였다. 생육측정은 2010년 4월부터 10월까지 초장, 엽수, 꽃대직경, 소화수, 엽록소 함량, 지상부 생체중 및 건조중 등을, 생존율은 이듬해인 2011년 5월에 조사하였다. 1. 인공배합토 100%($A_1O_0$)처리구의 경우, 검은색 부직포 멀칭에서 리아트리스의 엽수, 소화수, 엽록소 함량 등이 높았고, 특히, 초장, 지상부 생체중, 지상부 건조중 등은 다른 멀칭처리에 비해 확연한 차이를 보였다. 동면 후 생존율은 무처리와 난석 멀칭이 100%, 바크 멀칭에서는 20%,검은색 부직포 멀칭에서는 0%의 생존율을 보였다. 2.인공배합토 80%, 유기질 비료 20%($A_4O_1$)의 경우, 검은색 부직포 멀칭에서 리아트리스의 초장, 엽수, 소화수, 지상부, 생체중, 지상부 건조중 등이 다른 멀칭처리에 비해 높았으나, 초장을 제외하고 뚜렷한 차이를 보이지 않았다. 동면 후 생존율은 $A_1O_0$와 비교해볼 때 약 40~60% 정도 감소하였다. 3. 인공배합토 50%, 유기질 비료 50%($A_1O_1$)의 경우, 검은색 부직포 멀칭이나 바크 멀칭에서 리아트리스의 초장, 꽃대직경, 소화수, 엽수, 엽록소 함량, 지상부 생체중, 지상부 건조중 등이 다른 멀칭처리에 비해 좀 더 높았으나 통계적인 유의성은 없었다. 동면 후 생존율은 모든 멀칭처리에서 0%를 나타냈다. 따라서, 무관수 옥상녹화에서 리아트리스의 생육과 개화는 검은색 부직포 멀칭에서 가장 양호하였다. 반면, 동면 후 생존율은 유기질 비료의 비율이 높을수록 저하되는 경향을 보였다. This research evaluated the effectiveness of organic matter ratios in substrate and mulching materials under mn-irrigated condition green roofs by measuring the effects on growth of Liatris spicata. Four mulching materials were installed, i. e. nun-mulched control(CON), volcanic ash soils(VAS), non-woven black fabric mat(NBM) and pine bark(PAK). Three levels of organic maller volume percentage in an amended soil were evaluated, amended soil: organic matter=100:0($A_1O_0$), amended soil: organic matter=80:20($A_4O_1$) and amended soil: organic matter=50:50($A_1O_1$). Plant height, number of leaves, diameter of flower stalk, number of florets, chlorophyll contents, shoot fresh and dry weight were recorded from April to September, 2010, and survival rate was examined on May 2011 of the following year. In the $A_1O_0$, the number of leaves, number of florets and chlorophyll contents were higher in Liatris spicata grown on NBM than other mulching treatments. Especially, plant height, shoot fresh and dry weight were significantly higher. However, it resulted the lowest survival rate than other mulching treatments. 2. In the $A_4O_1$, the plant height, number of leaves, number of florets, shoot fresh and dry weight were higher than other mulching treatments, but there was no significant difference except for the plant height of Liatris spicata grown on NBM. The survival rate was decreased by 40~60%, compared with $A_1O_0$, after overwintering. 3. In the $A_1O_1$, the plant height, number of leaves, diameter of flower stalk, number of florets, chlorophyll contents, shoot fresh and dry weight were slightly higher than other mulching treatments, but there was no significant difference from Liatris spicata grown on NBM and VAS. The survival rate was observed by 0% over all mulching treatments after overwintering. Therefore, the non-woven black fabric mat(NBM) promoted the Liatris spicata's growth and flowering compared with other mulching treatments. However, the survival rate was decreased significantly, and the organic matter ratios were increased after overwintering under non-irrigated green roofs.

주진희,송희연,오득균,박선영,윤용한,Ju, Jin-Hee,Song, Hee-Yeon,Oh, Deuk-Kyun,Park, Sun-Yeong,Yoon, Yong-Han 한국환경과학회 2021 한국환경과학회지 Vol.30 No.9

This study evaluated the growth, physiological responses and productivity based on the intercropping ratio of cherry tomato (Lycopersicon esculentum L.) with basil (Ocimum basilicum L.). on the rooftops to determine out the efficient ratio in urban agriculture. From April to September 2019, an experiment was conducted on the rooftop of Konkuk University Glocal Campus. Cherry tomato and basil were selected as companion plants for eco-friendly urban agriculture on the rooftops. Each plot was created with a width of 100 cm, length of 100 cm, and height of 25 cm. After installing drainage and waterproof layers from bottom to top, substrate was laid out with a height of 20 cm. Intercropping ratio was consisted of a single tomato plant (TC), 2:1 tomato to basil (T₂B₁), 1:1 tomato to basil (T₁B₁), 1:2 tomato to basil 2 (T₁B₂), and a single basil plant (BC), were conducted using a randomized complete plot design with five treatments and three replication (a total 15 plots). Measurements were divided into growth, physiological responses, and productivity parameters, and detailed items were investigated and analyzed by classifying them into plant height, leaf length, leaf width, number of leaves, root length, root collar caliper, chlorophyll contents, fresh weight, dry weight, number of fruit, fruit caliper, fruit weight, and sugar content. Comparative analyses of cherry tomato with basil plants by intercropping ratio, growth, physiological, and productivity responses are determined to be efficient when the ratio of cherry tomato to basil ratio is 2:1 or 1:1.

빗물활용 옥상녹화 식재지반에 따른 한라구절초의 생육 변화

주진희,김원태,윤용한,Ju, Jin-Hee,Kim, Won-Tae,Yoon, Yong-Han 한국조경학회 2011 韓國造景學會誌 Vol.39 No.1

본 연구는 빗물 활용 옥상녹화에서 식재기반 차이에 따른 한라구절초의 생육 변화를 살펴보고, 적합한 토심과 토양배합비를 제시함으로써 옥상조경 식물소재로 활용성을 높이고자 한다. 토심(15cm, 25cm)과 토양배합비(SL, $P_7P_1L_2$, $P_6P_2L_2$, $P_5P_3L_2$, $P_4P_4L_2$)를 각각 다르게 실험구를 조성하였으며, 내건성과 관상가치가 뛰어난 한라구절초를 식재한 후 초장, 녹피율, 엽록소 함량, 생체중과 건조중, T/R율 등을 측정하였다. 토심 15cm처리구에서 토양배합비에 따른 한라구절초의 초장의 경우 통계적 유의성은 발견되지 않으나, 전반적으로 PPL배합토인 $P_7P_1L_2$, $P_6P_2L_2$, $P_5P_3L_2$, $P_4P_4L_2$가 사양토인 SL보다 높았다. 토심 25cm처리구의 경우, SL < $P_7P_1L_2$, $P_6P_2L_2$, $P_5P_3L_2$ < $P_4P_4L_2$ 순으로 초장이 길었다. 녹피율의 경우 토심 15cm처리구에서는 초장과 같이 토양배합비에 의한 차이는 뚜렷하지 않았으나, 수치적으로는 SL처리구에서 가장 낮았다. 토심 25cm처리구의 전체적으로 86~89%의 높은 피복률을 나타냈다. 엽록소 함량은 토심 15cm처리구에서 SL이 가장 높게, $P_5P_3L_2$이 가장 낮았으며, 토심 25cm처리구에서는 $P_4P_4L_2$과 SL에서 가장 높은 값을, $P_7P_1L_2$에서 가장 낮은 값을 보였다. 생체중과 건물중의 경우 배합비보다는 토심에 따른 차이가 더 뚜렷하여 토심 25cm처리구가 15cm처리구보다 높았다. 따라서 빗물활용 옥상녹화 식재지반에 있어 한라구절초의 생육은 토심 25cm가 토심 15cm보다, PPL배합토, 특히, 피트모스함량이 높은 $P_4P_4L_2$이 사양토보다 더 적합한 생육환경을 제공해 주는 것으로 분석되었다. This study aims to suggest a suitable soil thickness and soil mixture ratio of a green roof system by verifying the growth of Chrysanthemum zawadskii var. coreanum as affected by different green roof systems using rainwater. The experimental planting grounds were made with different soil thicknesses(15cm, 25cm) and soil mixing ratios (SL, $P_7P_1L_2$, $P_6P_2L_2$, $P_5P_3L_2$, $P_4P_4L_2$) and with excellent drought tolerance. Ornamental value Chrysanthemum zawadskii var. coreanum was planted. The change in plant height, green coverage ratio, chlorophyll content, fresh weight, dry weight, and dry T/R ratio of Chrysanthemum zawadskii var. coreanum were investigated from April to October 2009. For 15cm soil thickness, the plant height of Chrysanthemum zawadskii var. coreanum was not significantly different as affected by the soil mixing ratio. However, it was found to be higher in the amended soil mixture, $P_7P_1L_2$, $P_6P_2L_2$, $P_5P_3L_2$ and $P_4P_4L_2$ than in the sandy loam soil, as it was SL overall. For 25cm soil the plant height differences were in order to SL < $P_7P_1L_2$, $P_6P_2L_2$, $P_5P_3L_2$ < $P_4P_4L_2$. The green coverage ratio was observed not to be different by soil mixing ratio with soil thickness of 15cm, but, the lowest green coverage ratio in the SL. In the 25cm soil thickness, the green coverage ratio was 86-89% with a good coverage rate overall. The change in chlorophyll contents with 15cm soil thickness was found to be the highest in the SL treatment and the lowest in the $P_5P_3L_2$ treatment. For 25cm thickness, the highest value was in the $P_4P_4L_2$ and SL, and the lowest in the$P_7P_1L_2$. Fresh weight and dry weight were larger in soil with 25cm thickness. Therefore, the growth of Chrysanthemum zawadskii var. coreanum as affected by a different green roof system for using rainwater was higher in soil with 25cm thickness than 15cm, and in PPL amended soil than in sandy loam.

겨울철 염화칼슘(CaCl₂) 처리에 따른 가로변 3가지 상록 관목류의 생육 및 생리반응 - 사철나무, 영산홍, 회양목을 중심으로 -

주진희,박지연,허혜,이은엽,현경학,정종석,최은영,윤용한,Ju, Jin-Hee,Park, Ji-Yeon,Xu, Hui,Lee, Eun-Yeob,Hyun, Kyoung-Hak,Jung, Jong-Suk,Choi, Eun-Young,Yoon, Yong-Han 한국조경학회 2016 韓國造景學會誌 Vol.44 No.2

본 연구는 도심 내에서 공원 및 가로수 주변에 식재된 대표적인 세 가지 상록 관목류인 사철나무(Euonymus japonica), 영산홍(Rhododendron indicum), 회양목(Buxus koreana) 등을 중심으로 겨울철 염화칼슘($CaCl_2$) 처리에 따른 생육 및 생리적 반응을 살펴봄으로써, 내염성 정도와 제설제 피해지역에 대한 내성수종을 선별하기 위한 자료로 제시하고자 한다. 염화칼슘을 각각 0%(대조구), 0.5%, 1.0%, 3.0%, 5.0% 처리한 실험구에 2014년 11월에 정식한 후 이듬해 이른 봄인 2015년 3월에 수고, 엽장, 엽폭, 엽형지수, 엽수, 생체중, 건조중, 건물률, R/T율, 엽록소함량, 엽록소형광반응, 광합성률, 기공전도도, 증산율 등의 생육 및 생리적 특성을 조사하였다. 사철나무는 3.0% 이하, 영산홍과 회양목은 1.0% 이하의 처리구에서 생존이 가능하였으며, 사철나무가 영산홍과 회양목에 비해 생육적 감소율이 비교적 낮았다. 염화칼슘 처리농도가 높을수록 대조구에 비해 생리적 반응들이 감소되는 것은 동일하나, 영산홍과 회양목은 감소세가 비교적 뚜렷한 반면, 사철나무가 완만한 감소세를 보이고 있다. 특히, 처리농도가 높아짐에 따라 영산홍은 증산율을, 회양목은 광합성율과 기공전도도를 억제시키는 경향을 보였다. 이러한 결과를 통해 사철나무가 영산홍과 회양목에 비해 염해에 좀 덜 민감한 수종임을 알 수 있어 제설제 피해지역에 상록 관목류로 적용이 가능할 것으로 본다. It is important to know the sensitivity of shrubs to de-icing salt in order to set guidelines for ecological tolerance of evergreen shrubs along roads. Therefore, the aim of this study was to investigate the influence of de-icing salt, calcium chloride($CaCl_2$), on the growth and physiological characteristics of three evergreen shrubs, Euonymus japonica, Rhododendron indicum, and Buxus koreana. Plants were exposed to calcium chloride at different concentrations(weight percentage, 0% as control, 1.0%, 3.0%, and 5.0%) through amended soil maintained from the start of the experiment in October of 2014 until termination in March of 2015. The survival rate, plant height, leaf length, leaf width, leaf shape index, number of leaves, fresh weight, dry weight, dry matter, root/top ratio, chlorophyll contents, fluorescence, photosynthesis, stomatal conduct, and transpiration rate were recorded. Elevated calcium chloride concentrations decreased plant height, leaf length, leaf width, leaf shape index, fresh weight, dry weight, dry matter, and R/T ratio of the three shrubs. Root growth responded more sensitively than the top growth to salinity. However Euonymus japonica was more tolerant to salt stress than Rhododendron indicum and Buxus koreana. Their growths were totally inhibited by $CaCl_2$ above 3.0% and 1.0% concentrations, respectively. Chlorophyll content, fluorescence, photosynthesis, stomatal conduct, and transpiration rate of both Rhododendron indicum and Buxus koreana were reduced sharply, while Euonymus japonica exhibited mild reductions compared to plants grown in control when increasing calcium chloride was used. Especially, the transpiration rates of Rhododendron indicum, and the photosynthesis and stomatal conduct of Buxus koreana were suppressed as the concentrations of calcium chloride increased. Therefore, Euonymus japonica should be considered as an ecologically tolerant species with proven tolerance to de-icing salt.

도시 내 중금속 오염지의 관상식물로서 자생 맥문동(Liriope platyphylla)의 적용성 평가

주진희,윤용한,Ju, Jin-Hee,Yoon, Yong-Han 한국조경학회 2014 韓國造景學會誌 Vol.42 No.5

본 연구는 토양 내 중금속(카드뮴, 납, 아연) 처리 농도에 따른 자생 맥문동의 외형적인 생장 변화를 살펴봄으로써, 도시 내 중금속 오염지의 관상효과 증진을 위한 수종탐색 자료로 활용하고자 수행하였다. 중금속은 카드뮴, 납, 아연등 3종류이고, 처리 농도는 Control, 100, 250, $500mg{\cdot}kg^{-1}$ 등 4가지로서, 총 12가지 처리구로 구성하였다. 2009년 3월에 각각의 실험구에 10개씩 3반복으로 각 처리구에 정식하여, 같은 해 9월까지 약 7개월간 온실에서 실험을 실시하였다. 생장이 가장 활발한 시기라 볼 수 있는 5월부터 8월까지 약 3개월 동안 엽장, 엽폭, 총엽수, 고사엽수, 신엽수, 엽록소함량, 관상가치 등을 중심으로 생장 변화를 모니터링하였다. 카드뮴(Cd) 처리구의 경우, 엽장과 엽폭의 상대생장률이 식재 후 4개월이 경과된 시점에서 급속히 감소하였다. 총엽수, 신엽수, 엽록소함량, 관상가치 등의 형태적 항목에서도 Control> $Cd_{100}$ > $Cd_{250}$ > $Cd_{500}$ 순으로 감소하는 경향을 보였다. 납(Pb) 처리구에서 엽장의 상대생장률은 $Pb_{250}$과 $Pb_{500}$ 처리구에서만 변화율이 감소한 반면, 엽폭은 납 처리 농도가 높을수록 성장률의 감소양상이 뚜렷하였다. 총엽수, 신엽수, 고사엽수등은 대조구와 $Pb_{100}$ 처리구에서 비교적 유사하였으나, 엽록소함량, 관상가치 등은 납 처리 농도가 증가할수록 감소양상이 매우 뚜렷했다. 아연(Zn) 처리구는 카드뮴와 납 처리구와는 달리 식재 후 4개월이 경과된 시점에서도 변화율의 차이가 있을 뿐, 엽장은 꾸준히 증가하는 경향을 보였다. 엽폭 상대성장율 또한 $Zn_{500}$ 처리구를 제외하고, 비교적 완만한 성장세를 보였다. 총엽수, 신엽수, 고사엽수, 관상가치는 $Zn_{500}$ 처리구에서 가장 낮은 값을 나타낸 반면, Control, $Zn_{100}$, $Zn_{250}$ 처리구간에 차이가 뚜렷하지 않았다. 본 연구를 통해, 맥문동의 관상가치적 관점에서 생장 변화를 파악함으로써 향후 현장적용의 기반 연구로서 큰 의미를 갖는다고 하겠다. 하지만, 중금속에 대한 식물의 내성은 중금속 자체의 특이성과 환경조건에 따라 변화할 수 있다는 개연성을 가지므로, 실내연구와 현장적용성 연구가 병행되어야 할 것이다. Heavy metal pollution is a widespread global problem causing serious environmental concern. Heavy metals such as Cd, Pb, and Zn can induce toxicity in all organisms if the soil levels of contaminants reach critical values. The aim of the present study was to examine the application of Liriope platyphylla, an ornamental Korean native plant with great potential for contaminated soil in urban areas, to determine tolerance for Cd, Pb, and Zn. Plants were grown in amended artificial soil with Cd, Pb, and Zn at 0, 100, 250, and $500mg{\cdot}kg^{-1}$ for 7 months. The length of leaf, width of leaf, total leaf number, dead leaf number, new leaf number, chlorophyll contents, and ornamental value were monitored from May to August, during growth the period. The relative leaf length and leaf width displayed rapidly decreasing tendencies with an increasing Cd concentration beginning from 4 months after planting. The same decreasing tendency was observed in total leaf number, new leaf number, chlorophyll contents, and ornamental values showed a trend of Control> $Cd_{100}$ > $Cd_{250}$ > $Cd_{500}$. In Pb concentration treatments, the relative leaf length and leaf width were significantly lower in plants grown at $250mg{\cdot}kg^{-1}$ and $500mg{\cdot}kg^{-1}$ as compared to the Control, $100mg{\cdot}kg^{-1}$. The total leaf number, new leaf number, and dead leaf number did not show significant difference among treatments in Control and $Pb_{100}$ but chlorophyll contents and ornamental value decreased with increasing Pb supply concentration treatments. However, in Zn supply treatments, the relative leaf length was higher at $100mg{\cdot}kg^{-1}$ than the Control, $250mg{\cdot}kg^{-1}$, $500mg{\cdot}kg^{-1}$, but the relative leaf width decreased compared to the Control, $Zn_{100}$, $Zn_{250}$, and $Zn_{500}$. The total leaf number, dead leaf number, new leaf number, and ornamental value showed the lowest value in plants grown in $Zn_{500}$ treatment but no significant differences were found among other treatments.

주진희,방광자,Ju, Jin-Hee,Bang, Kwang-Ja 한국조경학회 2005 韓國造景學會誌 Vol.32 No.6

본 연구는 실내에서의 관수주기, 상토종류, 배수층의 유$\cdot$무에 따른 가는쇠고사리의 생육을 살펴봄으로써 실내조경용 식물소재로 활용 및 관리 방법에 관한 자료를 제공하고자 수행하였다. 관수주기는 주 2회와 주 7회로 처리하였으며 배수층은 각 관수주기 처리별로 500mm 깊이의 마사토로 처리하였다. 상토는 자연토인 마사토:부엽토=1:1와 인공토인 피트모스:버미큘라이트:펄라이트=1:1:1을 사용하였다. 1. 2가지의 상토의 화학적인 특징을 분석한 결과 토양산도, 치환성 양이온함량은 피트모스:버미큘라이트:펄라이트=1:1:1 처리에서, 전기전도도, 유기물함량, 유효인산, 전질소함량, 양이온치환용량은 마사토:부엽토=1:1 처리에서 높은 수준을 보였다. 2. 관수주기에 있어 주 2회 관수처리가 주 7회 관수처리보다 가는쇠고사리의 생육과 실내 적응성이 높아 양치식물이 높은 수분환경을 선호함에도 불구하고 과도한 관수는 바람직하지 않는 것으로 사료된다. 3. 상토에 다른 가는쇠고사리의 생육과 실내 적응성은 마사토:부엽토=1:1 처리가 피트모스:버미큘라이트:펄라이트=1:1:1 처리에 비해 높았다. 그러나 실내에서는 자연토의 하중문제가 발생될 수 있으므로 추후 이를 대체할 수 있는 경량의 인공토양이 개발되어야 할 것이다. 4. 배추층의 유$\cdot$무에 의한 가는쇠고사리의 생육결과, 주 2회 관수처리에서는 배수층에 유$\cdot$무에 따른 생육적 차이가 크지 않았으나 주 7회 관수처리에서는 배수층이 있는 처리구가 생육과 실내 적응성이 높았다. It was aimed to promote as a material for interior landscape by validating Rumohra aristata, in an indoor environment, especially irrigation interval, medium composition and drainage at indoor. 1. The result of physico-chemical analysis of medium composition showed that porosity, pH and Ex-Ca, Ex-Mg and Ex-K were high with peatmoss: vermiculite: perlite(1:1:1) and water contents, organic matter content, total nitrogen and cation exchange capacity were high with sand: leaf mold(1:1). 2. Growth and indoor adaptability of Rumohra aristata were better with irrigation at 2 interval per week than irrigation at 7 interval per week regardless of drainage. 3. In the case of medium composition, of growth and indoor adaptability were higher with sud: leaf mold (1:1) than peatmoss: vermiculite: perlite(1:1:1). 4. Fronds fresh weight and dry weight decreased when irrigation interval increased and were higher with sand: leaf mold(1:1) than peatmoss: vermiculite: perlite(1:1:1) treatment.

주진희,김태연,윤용한,Ju, Jin-Hee,Kim, Tae-Yeon,Yoon, Yong-Han 한국환경과학회 2022 한국환경과학회지 Vol.31 No.5

Production of lettuce under indoor cultivation is highly affected by light intensity. In this study, we used shade cloth (commercial black net) to examine the effect of these condition on growth without an associated yield penalty of container-grown lettuce. Four levels of shading treatments (0%, 35%, 55%, and 75% referred to as Cont., S₃₅, S₅₅, and S₇₅ with respect to Cont.) and two lettuce varieties (red and blue) were evaluated. Variety-specific growth responses were observed with respect to different levels of shading treatments. High growth of red lettuce was occurred in Cont. treatment despite plant height and leaf length being higher than Cont. However, under 35% shading treatment blue lettuce was higher than in control plants. The highest root length was observed 0% shading (Cont.) of both varieties. These results reinforce the idea that blue lettuce is the better leafy vegetable rather than red lettuce for indoor cultivation related to lower light intensity environment conditions.

하이드로컬쳐 부피비와 화분용토에 따른 스킨답서스, 싱고늄의 실내습도 개선효과

주진희,Ju, Jin-Hee 한국조경학회 2009 韓國造景學會誌 Vol.37 No.4

본 연구는 하이드로컬쳐 실내녹화방법을 실내습도 개선의 중요한 수단으로 활용하기 위해, 관엽식물로 매우 보편화된 스킨답서스(Scindapsus aureus)와 싱고늄(Syngonium podophyllum)을 대상으로 하이드로컬쳐 식재 부피비율인 2%, 3%, 5% 차이와 3%의 동일한 하이드로컬쳐 식재대에서의 화분용토, 식물종의 차이에 따른 실내습도 변화를 실측하였으며, 그 결과는 다음과 같다. 하이드로컬쳐 부피비율에 따른 습도 변화에 있어서 스킨답서스의 경우, 식물이 투입하지 않았던 대조구에 비해 식물이 있는 생장상 내 상대습도가 높았다. 특히, 식물과 식재대의 용적비율이 높아질수록 습도가 높아졌다. 상대습도 25%인 대조구에 비해, 2%는 40%를, 3%는 45%를, 5%는 50%로 측정되었다. 싱고늄은 하이드로컬쳐 부피비율 2%는 40%를, 3%는 44%를, 5%는 46%로 각각 나타내어 대조구인 25%의 상대습도보다는 높았으나 부피비율에 따른 상대습도 차이는 확연하지 않았다. 하이드로컬쳐 식재대 내의 화분용토와 식물종에 따른 상대습도 변화를 살펴보면, 대조구인 하이드로볼 식재대 내의 하이드로볼 처리구에서 초기 상대습도가 다소 높았으나, 시간이 지남에 따라 물 식재대 내의 흙화분 처리구와 유사한 약 45%의 상대습도를 유지하였다. 물 식재대 내의 하이드로볼 처리구에서 상대습도가 약 30%로 나타났으며, 하이드로볼 식재대 내의 하이드로볼 처리한 산호수는 상대습도 약 38%로 측정되었다. The purpose of this study was to utilize hydroculture by the vital means of the improvement of indoor relative humidity. This experiment employed a search of the effect of Scindapsus aureus and Syngonium podophyllum that are generalized for hydroculture foliage plant by a difference of volume ratio, pot media and plants species. In the case of Scindapsus aureus, relative humidity was high for growth chamber in which plants presented as opposed to control growth chambers in which there were no plants. Although relative humidity was 25% in control chamber, there was an increase of 40% at a 2% volume ratio, 45% at a 3% volume ratio and 50% at a 5% volume ratio. The relative humidity of Syngonium podophyllum was 40% at a 2% volume ratio, 44% at a 3% volume ratio and 46% at a 5% volume ratio, while the control treatment was 25% relative humidity in hydroculture. Both the control treatment and hydroball pot in a hydroball container were high at first. As time progressed, artificial soil pots in water containers was similar when housed within the control chamber by about 45% relative humidity. Hydroball pots in water container had about 30% relative humidity. Ardisia pusilla of hydroball poIt in hydroball container had about 38% relative humidity.

This study was conducted to examine the growth and physiological characteristics of Asplenium scolopendrium native fern as affected by irrigation times and soil media as an environment modeled on habitate where was sunken-condition. 1. Light intensity was lower in sunken than in non-sunken, but air humidity was higher in sunken about $2040\%$. Soil moisture content was higher with the leaf mold in sunken irrigating 2 times/week. The results of chemical analysis of medium showed that EC, pH, organic matter content, total nitrogen, CEC, Exch-Ca, Exch-Mg and Exch-K were higher with leaf mold than sud: leafmold and field soil: sud: leaf mold. 2. In the case of irrigation 2 times/week Asplenium scolopendrium grew well sunken more than non-sunken. As non-sunken condition similar with, 7 times/week irrigation, plant height, frond width, frond length and stipe length increased. In case of soil media, growth of Asplenium scolopendrium was better with leaf mold than that of sand: leafmold or field soil: sand: leaf mold. 3. In the case of irrigation 2 times/week photosynthetic rate, $CO_2$ absorption rate and water efficiency were higher with non-sunken than that of sunken, expect of stomatal conduction, $CO_2$ use efficiency. The physiological characteristics of Asplenium scolopendrium were highest in non-sunken irrigating 7 times/week In case of soil media, physiological activity was higher with leaf mold than sand: leafmold or field soil: sand: leaf mold.
