This study analyzed indoor and outdoor thermal performance among different types of green roofs and green walls in order to provide information for building greening. When temperature reduction effects of green roofs and green walls were compared to the control, the effects was highest at the green roof and wall treatment, followed by green wall, green roof, and the control, which means there was temperature reduction effects by building greening. Also these temperature reduction effects was influenced by outdoor weather condition such as being typically high in sunny days but not notable in rainy days. In addition temperature reduction was effective as the air temperature was up but was not influenced by wind velocity. As for directions, the west side showed the highest temperature followed by the south and east in the order. Heat flow was found greater in control than in green roof and green wall. In addition, heat flow reversal was found as time went on.

Salt tolerance in Iris pseudacorus L. was tested whether it can be materialized to remove salt accumulation in water caused by nonpoint source pollution. Two groups of treatments were a nutritive salt group (NSG) of Hoagland solution of varying concentrations and a sodium salt group (SSG) of the solution of NaCl. In NSG leaf visible damages appeared in more than EC 5 mS·cm-1, while plants in SSG showed visible damage in all concentrations of NaCl. The damage symptoms were dark green in leaves and plant wilting in NSG, while browning of the leaf tips' browning in SSG. Plant biomass in NSG was highest in EC 1 mS·cm-1 the lowest in EC 9 mS·cm-1. In SSG, it was significantly decreased as salt concentration increased. Photosynthetic and root activities were reduced, and proline, a kind of stress-defense proteins, increased, accompanied with salt increase.

This study was investigated the effect of heating time (taken the pots transplanted perennial root in heating greenhouse from Dec. 30 to Mar. 2 as 10 days interval) after 1st cut-flower harvesting on the growth, flowering time, and cut-flower productivity of domestic bred Gypsophila paniculata ‘Dream Song’ in plain area. As the later heating time, the shorter days to shoot emergence and flower budding as the longer exposed to low temperature, and blooming was promoted with increasing the air temperature within greenhouse. Flower stalk length, node number, and stem diameter were inclined to decline in later heating time. In Dec. 30 heating time, node number on a main stem was many, but primary branches number was low due to insufficient breaking of dormancy. Cut flower length was not significantly different as affected by heating time, fresh weight got declined as the later heating time and then drastically decreased in Mar. 2. Cut-flower yield was not significantly different among heating time except for both Dec. 30 insufficiently exposed to low temperature and Mar. 2 shortened the growth duration caused by relatively high temperature. It was thought that the dormancy of ‘Dream Song’ broke after the middle of January under natural low temperature, and the production of second crop should be cultivated within Feb. 20 from mid January.

This study was conducted to investigate the effect of ultraviolet light (UV-B) on plant growth and petal antioxidants of edible flower pansy (Viola × wittrochiana ‘Rose’ and ‘Yellow’, V. cornuta ‘Purple’). The plants were grown under white LED of 100 μmol·m-2·s-1 PPFD and treated by UV-B of 10, 20 and 30 minutes per day: UVB-10, UVB-20, and UVB-30 respectively. The plant growth was significantly inhibited as longer UV-B radiation exposure, even ‘Rose’ could not f lower under UVB-30. NPQ increase was observed in all cultivars with longer UV-B irradiation exposure. Also, anthocyanin in ‘purple’ and ‘Rose’ or carotenoid in ‘Yellow’ increased in the petals as longer UV-B radiation exposure. Unexpectedly the contents of total phenol and DPPH did not show the significance in UV-B treatments. In conclusion, the applicable UVB exposure to edible pansy in order to more accumulate antioxidants in petals would be in 20 minutes per day.

In this study, three greenhouse farms in Wonju (northern), Seosan (central), and Jeju (southern), which are main producing regions of lilies, were selected, and the impact of regional cultivation environmental factors on the quality of lilies were investigated with cut flowers of Oriental Lily ‘Siberia’. Greenhouse environments such as temperature, humidity, and integrated light have been analyzed since January 2016. The correlations between climate factors and cut flower qualities were determined. As a result, the vase life had a highly positive correlation with dew point (r = 0.73***). The temperature had a negative correlation with flower stalk length (r = -0.80***), while a positive correlation with flower bud size (r = 0.67**). Effect of Integral light intensity on the cut quality and vase life was not much higher than temperature. These results confirmed the importance of greenhouse environmental control to produce lily cut flowers qualified for export.

A new Hibiscus syriacus ‘Danna’ was developed at the National Institute of Forest Science in 2013. It was initially derived from an artificial cross in 2004, between H. syriacus ‘Hanŏl’, a seed parent, a Korean local cultivar with vigorous growth and H. syriacus ‘Hanŏl-tanshim’, as a pollen parent, with long bloom period. ‘Danna’ was preliminarily selected as ‘KFRI-HH03’ for the aesthetic and stable quality of its unique color of its flower and rapid growth in elongation in 2008. Trial evaluation was conducted for 6 years (2008 - 2013), meanwhile, all investigated traits were retained in rooted cuttings originated from it. ‘Danna’ had a bright pink flower with very small red eye zone. Its flower diameter is 111.3 mm; length of red eye spot on petals is 13.8 mm. Leaves were 71.3 mm long and 43.1 mm wide, and petiole length was 14.2 mm. Flowering period of the cultivar investigated in 2013 was 81 days. It was registered as a new cultivar at the Korea Seed & Variety Service in 2015 (Grant Number 5756). Its tree habit shows vigorous and fast growth and is upright, so it can be used as an ornamental tree or a street tree.
