  • The soybean stay green mutant genotype (SSG) derived from the nuclear gene, d1d2, and cytoplasmic gene, cytG, inhibit the breakdown of chloroplast in the leaves, pod walls, seed coats, and embryos during maturity. Soybean seed with black seed coat and green cotyledon (SBG) are preferred than black seed coat with yellow cotyledon (SBY) especially for cooking with rice and as source of traditional food in Korea. The researchers evaluated the seed's chlorophyll content of SSG and introduced SSG to the SBG variety breeding program. The seed chlorophyll content of SSG with d1d2 was $39.93{\sim}60.80\;{\mu}g/g$ and SSG with cytG $38.08{\sim}39.89\;{\mu}g/g$. The Korean SBG variety which was derived from SSG with cytG, contains $16.35{\sim}37.73\;{\mu}g/g$. The composition of seed chlorophyll differs according to the genetic background of SSG genotype. Inheritance study showed that cotyledon color was segregated 15:1 (yellow:green) at $F_2$ seed indicating two recessive genes control green cotyledon as revealed by previous study. Only less than 3% soybean lines showed black seed coat with green cotyledon among crosses SBY and SSG (d1d2). Results showed that SSG with d1d2 can be used as a good source for SBG with high chlorophyll content in the seed cotyledon, but due to the complex genetic behavior, breeding resource of SBG with d1d2 should be prepared to improve the breeding efficiency for development SBG variety.

  • One of the most important paradigms in society has recently been a set of efforts to prepare for the future and to protect the environment by saving carbon that occurs in everyday life as well as in the industry. In order to successfully deal with this new paradigm, Korean government has adopted and implemented various policies including the green certification, the development of green technologies and green growth. Many agencies and organizations in both public and private sectors have established plans about the carbon savings and performed a lot of research using IT technology. For example, attempts have been made in Korea to use as electronic documents instead of paper documents using these green IT and mobile devices. This paper proposes a 'Paperless' waiting order count system using QR code and mobile phone as an example of green IT for 'Low carbon and Green growth'.

  • A new Saxifraga fortunei cultivar 'Whitegreen' was bred by crossing between 'Daewoojoo' with Pale Green (Y-G145-C) colored petals and 'Kwanglim' with light Yellow green (Y-G145A) colored petals. The selection and flower characterization were conducted from 2004 to 2008 in greenhouse of Highland Agriculture Research Center, NICS, RDA. Flowering in 'Whitegreen' Showed from September 20 th for 33 days. The number of petals were 11.4 ea., with a width of 1.4 cm and length of 1.4 cm. The plant height was 20.7 cm, and number of leaves per plant was 48.3 ea., with a width of 3.4 cm and length of 3.0 cm. 'Whitegreen' cultivar can be used as a pot flower. 'Whitegreen' plants grown under 50% shade of sunlight have higher degree of acclimation compared to those under direct sunlight. And soft rot disease would occur usually by over-irrigation. 'Whitegreen' cultivar was registered as a novel variety with No. 3456 in Korea seed and variety service on April 2011.

  • Taxonomic study of the genus Hemerocallis (Liliaceae) in Korea was conducted based on morphological data. H. middendorffii was distinguished from its related taxon H. dumortieri by the trait of coriaceous long bract with green color. H. taeanensis was distinguished from its related taxon H. minor by its odorless flowers, longer perianth tube and leaf length. H. thunbergii was distinguished from its related taxon H. lilioasphodelus by its long perianth tube. Lastly, H. hakuunensis was distinct from its related taxon H. hongdoensis as a result of its extreme branching of scape and short leaf width. From this study, it was revealed that H. minor, H. lilioasphodelus, and H. dumortieri were distributed only in the northern part of the Korean peninsular.

  • Life cycles of Sweltsa illiesi and S. lepnevae were determined from a headwater stream in Mt. Jumbong. Identification of nymphs was done by using DNA barcoding. Nymphs begin to have species specific color pattern on their head several months prior to adult emergence and differ in the form of the third antennal segment. Two species appear to have similar semivoltine life cycles in this stream, beginning to hatch from June and finishing adult emergence about 701 days later. The combined annual mean biomass in ash free dry mass (AFDM) was estimated as $96mg\;AFDM\;m^{-2}$. The combined annual secondary production were 373 mg and $297mg\;AFDM\;m^{-2}\;yr^{-1}$, calculated by using size frequency method and increment summation method respectively.

  • This study surveyed three land cover types in Chungju City in Chungcheongbuk Province to check the distribution of cultured bacteria in bio-aerosols according to land cover type. It was possible to compare and analyze the distribution of bacteria according to microclimatic changes at each measurement point by examining meteorological factors and bio-aerosols according to land cover. The microclimate temperature in each measurement point was 8.7℃ for the urban forest, 10.8℃ for the waterside green area, and 10.2℃ for the urban area, indicating the urban forest had the lowest temperature among the measurement points. The relative humanity was 61.8% fin the urban forest, 59.3% in the waterside green area, and 55.7% in the urban area, indicating that the urban forest was the most humid among the measurement points. The identified bacteria were found to be 43 genera and 99 species. In terms of species diversity of cultured bacteria, 22 genera were found in the waterside green area, 21 genera in the urban forest, and 17 genera in the urban area, 37 species were found in the waterside green area, 31 species in the urban area, and 31 species in the urban forest. Bacillus toyonensis and Pseudarthrobacter oxydan were the species present in all three types of measurement sites, and Herbiconiux flava was confirmed to inhabit green areas such as urban forests and waterside green areas. The analysis result of the bacterial concentration according to the microclimatic environment in each measurement point was 333 CFU/m3 in the urban forest, 287 CFU/m3, in the waterside green area, and 173 CFU/m3 in the downtown area. The relative humidity and wind speed were analyzed to show a similar trend as the concentration. This study is expected to provide basic data for healthy urban management and green area creation by identifying the distribution of cultured bacteria in bio-aerosols according to land cover type and comparing and analyzing the traits of bio-aerosol in each measurement point.

  • The Arabidopsis mutants involved in chloroplast development were induced by seed treatment of diepoxybutane which was rarely known mutagenic compound in plant mutagenesis. Three kinds of mutants designated as iml, gev, and yev were represented by the characteristics of variegated leaves, green vein with yellow leaves, and yellow green vein with green leaves respectively. We investigated the ultrastructure of chloroplast in mutated regions using transmission electron microscopy. The ultrastructure of chroloplast in wildtype showed regularly stacked grana thylakoid and stroma thylakoid while iml, gev and yev mutants displayed different shapes of grana stacking and stroma stacking of chloroplasts. Genetic analysis of three chloroplast mutants exhibit that divergent traits were ruled by a single recessive nuclear gene.

  • To make conservative port and coast ecosystems and creative the greenspace, We were investigated with characteristic of flora, environmental factors, types of port, adaptive species, minimum conservation area and plantation model. In 50 sites of study areas, there are 19 families and 174 species of vascular plants and 19 families and 48 species of halophytes. Dominant communities in port ecosystem contains Carex kobomugi community, Elymus mollis community, Carex pumila community, Ixeris repens community, Vitex rutundifolia community, Calystegia soldandlla community, Rosa rugosa community, Lathyrus japonica community, Salsola komarovi community, Cynodon dactylon community, Tetragonia tetragonioides community, Suaeda japonica community, Suaeda maritima community, Zoysia sinica community and Phragmites communis community. We carried out Canonical Correspondence Analysis(CCA) for ordinations on the vegetation and plant communities-environmental variable matrices in 50 sites. The communities tended to cluster into three types: Clay marsh, Sand marsh, Sand gravel marsh types. Adaptive species in habitate types are selected that sand marsh-type communities in ports contained Elymus mollis community, Ixeris repens community, Carex kobomugi community, Carex pumila community, Clay marsh-type communities contained Suaeda japonica community, Phragmites communis community, Zoysia sinica community and Suaeda maritima community, Sand gravel marsh-type communities contained Vitex rutundifolia community, Calystegia soldandlla community. We are conducted the estimation of minimal area for plantation of adaptive plant species and carried out guide line and plantation model for creation of green space in port ecosystem.
