Green rice leafhopper(GRH), Nephotettix cincticeps Uhier, is one of the major insect pests of rice (Oryza sativa L.) in the temperate growing region of East Asia. GRH sucks sap from both xylem and phoem of susceptible rice varieties, and increased GRH populations cause sooty mold disease on the ears of rice after heading stage. In addition to direct plant destruction, GRH also causes damage to rice plants by transmitting rice dwarf viruses causing rice dwarf viruses disease which could decrease the yield of rice. Development of GRH resistant rice varieties for reducing yield loss is an important objective in current breeding programs. In this study, we developed three SSR markers(RM18166, RM516, RM18171) and one Indel marker(Indel15040) which could select Grh1-resistant varieties using population derived from cross lines between Grh1-resistant variety ‘Singwang’ which contains Grh1 gene and susceptible variety ‘Ilpum’. PCR products of RM18166 which was one of the developed markers were easily detected in agarose gel. These markers will be useful for development of the Grh1-resistant varieties through marker-assisted selection(MAS) without bio-examination in rice breeding

A new standard rose cultivar ‘Green Star’ was bred from the cross between pink color standard cultivar ‘Pastel move’ and red color standard cultivar ‘Vital’ at the National Institute of Horticulture & Herbal Science.

The major characteristics of this cultivar are 122.0 stems/㎡/year in yield, 77.0±8.0 cm in length of cut flower, 12.1±0.4 cm in flower diameter, 37.7±4.2 in petal number, and 11.0±1.4 days in vase life. This cultivar can be propagated by both cutting and grafting. The consumer’s preference of this cultivar is relatively higher than that of control cultivar, ‘Moonlight’.

Tongil (IR667-98-1-2) rice, developed in 1972, is a high-yielding rice variety derived from a three-way cross between indica and japonica. Tongil contributed to staple food self-sufficiency of Korea, an achievement that was termed the ‘Korean Green Revolution’. In this study, we analyzed the nucleotide-level genome structure of Tongil rice and compared it to those of the parental varieties. A total of 17.3 billion Illumina Hiseq reads, 47× genome coverage, were generated from Tongil rice. Three parental accessions, two indica and one japonica types, of Tongil rice were also sequenced for approximately 30x genome coverage. A total of 2,149,991 SNPs were detected between Tongil and Nipponbare; the average SNP frequency of Tongil was 5.77 per kb. Genome composition based on the SNP data by comparing with the three parental genome sequences on sliding window of Nipponbare genome sequence revealed that 91.8% of the Tongil genome originated from the indica parents and 7.9% from the japonica parent, different from the theoretical expectation in a three-way cross, i.e., 75% indica and 25% japonica parental origins on average. Copy number of SSR motifs, ORF gene distribution throughout the whole genome, gene ontology (GO) annotation, yield-related QTLs or gene locations, and polymorphic transposon insertions were also comparatively analyzed between Tongil and parents using sequence-based tools. The results indicated that each genetic factor was transferred from parents into Tongil in proportion to the whole-genome composition. The Tongil rice is the first successful superior cultivar derived from indica × japonica hybridization in Korea. Defining of genome structure demonstrates that the Tongil genome is composed mostly of the indica genome with a small proportion of japonica genome introgression. This work was supported by a grant from the Next-Generation BioGreen 21 Program (Plant Molecular Breeding Center No. PJ008125), Rural Development Administration, Republic of Korea.

This study investigated the effects of soil depths and soil organic fertilizer application on the growth characteristics of Spiraea bumalda ‘Gold Mound’ in a extensive green roof system. The treatments were 3 soil depths (10, 15 and 25 cm) and 5 soil types in mixture of artificial soil and organic fertilizer. We measured plant height, leaf width, leaf length, number of flowers, visual quality and survival rate from March to October in 2011. The growing medium of 10 cm soil depth showed the highest plant growth in A1 (amended soil 100%), and the lowest plant growth in O1A4 (organic fertilizer 20% + amended soil 80%) treatment. In case of 15 cm soil depth, Spiraea bumalda ‘Gold Mound’ showed a high leaf length and visual quality in O1A2(organic fertilizer 33% + amended soil 67%) treatment and high leaf width and number of flowers in O1 (organic fertilizer 100%) treatment. A1 treatment without organic fertilizer showed the lowest leaf length and poorest visual quality, and O1A4 treatment showed the lowest plant height and lowest number of flowers. At soil depth 25 cm, O1A1 (organic fertilizer 50% + amended soil 50%) treatment showed greater plant height, visual quality and number of flowers than other treatments. The leaf length and leaf width were more effective in O1 treatment. A1 treatment showed a relatively low leaf length, leaf width and visual quality. The higher the organic conditioner, the better the plant growth. And, survival rates of Spiraea bumalda ‘Gold Mound’ showed 92%, 88% and 76% at soil depths of 25 cm, 15 cm and 10 cm, respectively, in this a extensive green roof system. Therefore, the results showed that the growth of Spiraea bumalda ‘Gold Mound’ was affected by both soil quality and soil depth. Different optimal mixtures of organic fertilizer and amended soil were determined, depending upon soil depth.

This study estimates the non-stationary design flow in the Upper Green River Basin (UGRB), WYby applying a moving window with the streamflow projections under A2, A1B, and B1 scenarios.The reliable estimates of design flow are necessary for the water management and planning andthe operation of infrastructure to reduce the risk of economic loss, the environmental damage,and the loss of life.The design flow is generally estimated by the flood frequency analysis under the stationaryassumption, which the historical flood distribution is similar to the future flooddistribution. However, nature is not stationary. This study considers the non-stationarity ofthe future streamflow in determining the design flow.To estimate the design flow, this study uses the 112 bias-corrected spatially downscaled(BCSD) precipitation and temperature projections of the World Climate Research Programme (WCRP)Coupled Model Intercomparison Project phase 3 (CMIP3) datasets. Furthermore, this study usesthe Variable Infiltration Capacity (VIC) model to simulate the streamflow projections underthree climate scenarios (A2, A1B, and B1). The non-stationary design flows for each year usinga moving window are estimated for 2, 5, 10, 20, 30, 50, and 100 year return periods using theGeneral Extreme values distribution.The proposed method is applied to the Upper Green River Basin in Wyoming. Moreover, thisstudy presents the climate change impacts on the design flow.

최근 이상기후로 인해 도시지역에서는 폭우재해로 인한 피해가 크게 발생하고 있다. 이에 대한 지금까지의 대응에는 하천, 하수도 등 전토적인 방재시설이 중요한 역할을 해 왔으나, 기존의 방재시설로 도시의 전체적인 방재성능을 향상시키는 것은 경제적․물리적 한계에 이르게 되었다. 따라서 공원녹지와 같은 비방재적 도시계획시설에 유출저감기능과 같은 방재성능을 추가하여 일정용량의 재해방지역할을 수행하도록 하는 새로운 도시방재수법이 필요하다. 특히 가상유역에 대한 공원녹지의 우수유출저감 모의분석을 한 결과, 공원녹지에 저류기능을 부가할 경우, 약 15%의 저감효과가 나타났음에 따라 공원녹지가 방재시설의 역할을 수행할 수 있을 것으로 예상된다. 따라서 본 연구에서는 폭우재해 발생 시 재해저감기능을 수행할 수 있는 공원녹지의 설계기법을 개발하고자 한다. 이를 위해서, 해외 방재관련 법제도의 검토와 가상유역에 대한 공원녹지의 우수유출저감능력 모의분석을 통하여 새로운 공원녹지 설계 가이드라인(이하 ‘공원녹지 설계기법’)을 작성하였다. 그리고 이 공원녹지 설계기법을 실제 공원녹지에 적용하여 시범설계를 함으로써 공원녹지 설계기법의 실제 적용 가능성을 평가하였다. 본 연구의 결과는 폭우재해 발생지역에 재해저감적응형 공원녹지를 설계할 수 있는 기준으로 활용할 수 있다.

본 연구는 효과적 벽면녹화 기술향상을 위하여 식물 생육, 시공 편리성, 공간 활용성 등 통합적 실용성을 갖춘 기능성 모듈을 개발하여 실내환경개선 효과를 알아보고자 하였다. 이를 공기정화 장치가 부착된 ‘Bio Green Wall System’에 구조화하여 직접 제작 설치 및 실용화하였다. ‘Bio Green Wall System’ 구조로 인해 식물에 의한 공기정화와 탄소봉에 의한 2차 공기정화 및 습도 조절이 가능하였고, 송풍 구조로 인해 화분의 후방으로 향해 있는 식물 뿌리에 산소를 공급하여 식물이 건강하게 생육하였다. 기능성 모듈 개발을 통해 다양한 식물의 선택이 가능하고, 간단한 공정으로 실내 및 실외의 여러 장소에 설치 및 이동이 가능하며, 식물의 교체나 보수도 신속하고 편리하게 할 수 있게 되었다. 실험결과, 식물이 없는 대조군보다 벽면녹화 설치 후 TVOCs와 미세먼지(PM10) 농도가 크게 감소하였으며, TVOCs는 ‘Bio Green Wall System’에서 일반 벽면녹화보다 더 많이 감소하였다. HCHO는 벽면녹화 설치 후 유의하게 감소하였으나 CO2에서는 유의한 차이가 없었다. 따라서 본 연구에서 개발된 ‘Bio Green Wall System’은 실내공기정화에 매우 효과적이며 특허출원한 기능성 모듈도 우수한 성능을 갖춘 것으로 나타났다.

시설재배지 토양에 녹비작물의 재배가 Biomass-C와 토양 양분의 변화에 미치는 영향을 평가하고자 pot(Ø10-cm)에 헤어리벳치, 호밀, 발랭이를 70일간 재배 후 식물체와 토양을 분리하여 분석한 결과가 다음과 같다. 녹비작물의 생육량은 호밀이 가장 많았으며, 질수흡수량은 헤어리벳치가 가장 높게 나타났다. 호밀 재배구가 토양의 인산함량은 가장 낮았으며, biomass C는 가장 높게 나타났다. 시험 후 토양의 질소함량과 식물체 질소 흡수량은 고도의 부의 상관을 보였다. T-N 함량은 헤어리벳치 시험구에서는 증가하였지만, 호밀과 바랭이 재배구에서는 감소하는 경향을 보였다. 이상의 결과를 요약해볼 때 시설재배지에서 가장 중요한 것이 토양의 염류집적(EC) 인데 시험 후 토양에서 대조구에 비해서 콩과인 헤어리벳치는 EC가 약간 증가했고 다른 무기성분은 큰 변화가 없으며, 화본과인 호밀은 EC와 다른 무기성분도 약간 감소하는 경향으로 시설연작재배지에서는 화본과 작물이 염류집적 경감을 위해서 유리하다

According to the increase of rural experience, that is important in satisfying needs of green tourism and vitalizing rural economy to use closed school in rural area as experience facility. For using closed school as experience facility, political and institutional assistants are needed in effective equipments and stable operation based on multi-perspective approach and analysis. In this study, we try to evaluate green-tourism accessibility of rural experience facility remodeled from closed school considering regional population and spatial characteristics. In evaluating process, gravity potential model are adapted with considering group size of customer and distance-friction coefficient. Distance-friction coefficient is a function of user restriction which depend on possible activity in each experience facility. Green tourism accessibility of experience facility is calculated with summation of accessibility to each region, and we analyzed it as a group by closed school type and location with application in Chungcheongnam-do. We found a correlation between green tourism accessibility of rural closed school and their income.

This was an experimental study to evaluate temperature reduction and evapotranspiration of extensive green roof. Three test cells with a dimension of 1.2(W)×1.2(D)×1.0(H) meters were built using 4-inch concrete blocks. Ten-centimeter concrete slab was installed on top of each cell. The first cell was control cell with no green roof installed. The second and third cells were covered with medium-leaf type Zoysiagrass (Zoysia japonica) above a layer of soil. Soil thickness on the second cell was 10cm and that on the third cell was 20cm. Air temperature, relative humidity and solar irradiance were measured using AWS (automatic weather system). Temperature on top surface and ceiling of the control cell and temperature on top surface, below soil and ceiling of green roof cells was measured. Evapotranspiration of the green roof cells were measured using weight changes. Compared with temperature difference on the control cell, temperature difference was greater on green roof cells. Between two green roof cells, the temperature difference was greater on the third cell with a thicker soil layer. Temperature differences below soil and on ceilings of green roof cells were found greater than those of the control cell. Between the green roof cells, there was no difference in the temperature reduction effects below soil and on ceilings based on substrate depth. In summary, green roof was found effective in temperature reduction due to evapotranspiration and shading effect.
