The seed spray technology prepares for landscape by spraying seeds, fertilizers and other materials but does not consider the relationship of the germination time and temperature of seeds for construction. The purpose of this study is to develop a functional formula that shows the relationship of germination and temperature for using the Papaver orientale L. seeds for the spray technology. The germination test in a chamber was progressed from March to April 2014 and the verification experiment proceeded in a greenhouse in May 2014. After culturing each 100 seeds of Petri dish and Papaver orientale L. seeds on filter beds 4 repetitive times, each 10mL of the first distilled water was sprayed to treat temperature at level 7 and the light source was maintained at 4~4.5μmoles/m²/s. The germination rate was investigated at two-day intervals, and the germination was based on the emergence of 3mm radicles. For experimental verification, seeding was implemented in a greenhouse and daily mean temperatures and germination periods were investigated. As a result of the treatment, based on a 50% germination rate, the functional relation between the temperature and germination period was found to be y = 1/-0.0004x²+ 0.0224x-0.0398, R2 = 0.9441. As the result of the analysis of the cardinal temperature from using graphs of functions, the lowest temperature was 2°C and the optimum temperature was 28°C and the highest temperature was 54°C, but in the actual test, normal germination was made at 5°C and the unusual germination of the final germination rate was below 50% at 35°C. In the experimental verification, as a result of substituting the daily mean temperature with functional formulas, it was found to be 4.4 days and the lapse of time for actual foliation was investigated to be 5.5 days.

A research related to a growth characteristic according to attach or not in accordance with wall materials and growth direction of 5 kinds of vine plants used in green-wall was proceed. Test was proceed from May to September 2010. Materials of wall used in the test are 6 kinds of timber, adobe, grass, brick, concrete and aluminum, and the vine plants used in the test are Euonymus radicans cv. aueonmarinata Rehd., Euonymus radicans Sieb. var. argenteo-marginatus Rehd., Campsis grandifolia (Thunb.) K. Schum., Schizophragma hydrangeoides Siebold & Zucc., Hedera rhombea (Miq.) Bean. Growth of the vine plants is high in a sequence of Campsis grandifolia (Thunb.) K. Schum., Hedera rhombea (Miq.) Bean, Euonymus radicans cv. aueonmarinata Rehd., Euonymus radicans Sieb. var. argenteo-marginatus Rehd., Schizophragma hydrangeoides Siebold & Zucc., and sheath rate of the vine plants is high in a sequenc of Campsis grandifolia (Thunb.) K. Schum., Euonymus radicans cv. aueonmarinata Rehd., Hedera rhombea (Miq.) Bean, Euonymus radicans Sieb. var. argenteo-marginatus Rehd., Schizophragma hydrangeoides Siebold & Zucc. However, Euonymus radicans Sieb. var. argenteo-marginatus Rehd., Schizophragma hydrangeoides Siebold & Zucc., Hedera rhombea (Miq.) Bean, are has a lower sheath rate compared to the growth rate. Difference of the growth according to north and south directions of the vine plants is that ampsis Hedera rhombea (Miq.) Bean., is high in the south direction, Campsis grandifolia (Thunb.) K. Schum., Schizophragma hydrangeoides Siebold & Zucc. and Euonymus radicans Sieb. var. argenteo-marginatus Rehd. has high growth rate in the north direction. And Hedera rhombea (Miq.) Bean. has high growth rate in the south direction on May~July and in the north direction on August~September. Attach or not according to materials of wall is that Campsis grandifolia (Thunb.) K. Schum. can be attached to timber, adobe, brick and concrete, Euonymus radicans Sieb. var. argenteo-marginatus Rehd. can be attached to brick and adobe, and Euonymus radicans cv. aueonmarinata Rehd., Schizophragma hydrangeoides Siebold & Zucc., Hedera rhombea (Miq.) Bean., can be attached to timber. However, all vine plants can not be attached to grass and aluminum.

실생활공간에서 포름알데히드 제거량이 구명되었으며, 그 값이 밀폐챔버 실험으로부터 계산된 이론적인 제거량과 비교되었다. 식물은 스킨답서스, 로즈마리, 치자나무가 사용되었으며, 방의 공간대비 3, 6, 9%에 해당되는 식물이 투입되었다. 공간대비 3, 6, 9%에 해당되는 식물이 투입되었을 때, 각각 30.9, 47.7, 67.0%의 포름알데히드가 제거되었으며, 반면에 4.8, 8.3, 10.0%의 상대습도가 증가하였다. 즉, 공간대비 1%의 실내식물이 투입될 경우 6-7%의 포름알데히드가 감소하는 것으로 나타났다. 생활공간에서 식물종류별 포름알데히드 제거능력에는 차이가 크지 않았다. 생활공간에서 직접 측정된 제거량과 챔버실험으로부터 계산된 이론적인 값의 비율은 0.05로 약 20배 차이가 났다. 결과적으로, 공간대비 1%의 실내식물 투입은 약 7%의 포름알데히드를 제거능력이 구명됨으로써 생활공간에서도 실질적인 공기정화 효과가 있는 것으로 구명되었다. The amount of formaldehyde removal by indoor pot plants was assessed in actual space, and compared with removal amount calculated from a sealed chamber test. Epipremnum aureum, Rosmarinus officinalis, and Gardenia jasminoide were placed in a room, occupying 3, 6, and 9% of the room volume, respectively. When each species occupied 3, 6, and 9% of the room volume, formaldehyde was removed by 30.9, 47.7, and 67.0%, and the relative humidity increased by 4.8, 8.3, and 10.0%, respectively. When pot plants occupied 1% of the room’s volume, formaldehyde was decreased by 6-7% in the room. A small difference in the rate of formaldehyde removal was observed among the species. The ratio of the formaldehyde removal measured in the room over the its theoretical removal calculated as the chamber test was found to be 0.05, approximately 20 folds. As a result, it has been found that indoor plants could be an effective method for the purifying of indoor air, according to the results suggesting that pot plants occupying about 1% of the room’s volume reduced formaldehyde by approximately 7%.
