박노복,임회춘,Park, Nou-Bog,Lim, Hoe-Chun 국립한국농수산대학교 교육개발센터 2005 현장농업연구지 = Journal of practical agricultural resear Vol.7 No.1
Tubers(4-5cm diameter) of Zantedeschia 'Black Magic' were used to study the induction of flowering in GA<sub>3</sub> soaking times and concentration. The GA<sub>3</sub> soaking were 10 seconds and 30 minutes at the GA<sub>3</sub> concentrations of 50, 100, 250, and 500 mg·L<sup>1</sup>. The time to emergence in GA<sub>3</sub> treatment were 1.1~4.0 days shorter than control Growth characteristics were good in GA<sub>3</sub> treatment but that was no significance in GA<sub>3</sub> soaking time and concentration. When GA<sub>3</sub> soaking time and concentration were increased, days to flowering was shorter, but flower stalk length, flower stalk width, flower length, flower width were no difference. The number of flower per tuber was most as 4.0~4.3 in 250~500 mg·L<sup>1</sup> GA<sub>3</sub> concentration and that was about 2 times compared to control. The normal flower ratio and bulb enlargement were similar compared with GA<sub>3</sub> soaking time and concentration. GA<sub>3</sub> 250~500 mg·L<sup>1</sup> treatment is necessary for improvement of number of flowers per bulb.

Growing agricultural products in greenhouses controlled by creating suitable climatic conditions and root zone of crop has been an important research and application subject. Appropriate environmental conditions in greenhouse are necessary for optimum plant growth improved crop yields. This study aimed to establish web-based remote monitoring system which monitors crops growth environment and status of crop on a real-time basis by applying to greenhouses IT technology connecting greenhouse equipment such as temperature sensors, soil sensors, crop sensors and camera. The measuring items were air temperature, relative humidity, solar radiation, CO<sub>2</sub> concentration, EC and pH of nutrient solution, medium temperature, EC of medium, water content of medium, leaf temperature, sap flow, stem diameter, fruit diameter, etc. The developed greenhouse monitoring system was composed of the network system, the data collecting device with sensors, and cameras. Remote monitoring system was implemented in a server/client environment. Information on greenhouse environment and crops is stored in a database. Items on growth and environment is extracted from stored information, could be compared and analyzed. So, A integrated monitoring system for smart greenhouse would be use in application practice and understanding the environment and crop growth for smart greenhouse management. sap flow, stem diameter and pant-water relations
유색칼라 ‘블랙매직’ 괴경의 저장온도 및 기간에 따른 생장반응
최소라(So Ra Choi),박노복(Nou Bog Park),김명준(Myung Jun Kim) 한국원예학회 2006 원예과학기술지 Vol.24 No.3
유색칼라 ‘블랙매직’의 적정 휴면타파와 저장조건을 구명하고자 수확 후 15±4℃에서 4주 동안 경화시킨 괴경의 저장 온도 및 기간에 따른 생장반응을 조사하였다. 괴경의 저장 조건인 18℃에서 4주와 24℃에서 2주부터 신초가 신장하기 시작하였으나 화아분화는 관찰되지 않았다. 신초 출현소요 일수와 개화소요일수는 저장온도가 높을수록, 저장기간이 길수록 단축되었다. 개화수는 신초 길이 변화가 시작된 처리구에서 비교적 많았는데 18℃의 6주 저장은 1.2개, 24℃의 2주 저장은 1.0개로 나타났으며 저장기간이 연장될수록 감소하였다. 8℃ 저장은 12주까지 개화수가 일정하게 유지되었다. 그러나 생육과 개화반응은 저장온도와 기간에 따른 차이가 없었다. The main objectives of this study was to determine the storage temperature and duration for breaking dormancy of calla lily ‘Black Magic’ tubers that hardened at 15 ± 4℃ for 4 weeks. The shoot growth from the tubers was initiated after 4 weeks at 18℃ or 2 weeks at 24℃, and flower initiation was not observed in any storage condition. The days to shoot emergence and flowering were shortened by storage temperature and duration increased. The number of flowers was increased when tubers were planted just after shoot elongation. However, the number of flowers was significantly reduced when tubers were still maintained in the storage period after shoot elongation. The best condition for storage was at 8℃ for 12 weeks, showing little change on the number of flowers. But other growth and flowering responses were little influenced by the storage temperature and duration.
NIH3T3 세포에서 UVB에 의한 세포고사와 DNA 단사절단에 미치는 fisetin의 효과

본 연구에서는 UVB에 조사된 NIH3T3 세포에서 세포고사와 DNA 단사절단에 미치는 fisetin후처리의 효과에 대해서 연구하였다. 세포에 UVB $(200J/m^2)$를 조사하고 정상배지에서 48시간 배양한 세포의 세포고사에 수반되는 핵분절은 50% 정도의 세포에서 관찰되었다. 흥미롭게도 배양배지에 fisetin이 첨가될 경우 핵분절을 보이는 세포의 빈도는 상당한 감소를 보였다. 알칼리 아가로스 겔에 의한 DNA 단사절단 분석에서 자외선 조사 후 fisetin처리는 정상배지 배양시보다 단사절단의 빈도를 감소시켜 DNA크기의 증가를 유도하였는데 이는 fisetin이 UVB에 의한 DNA 상해의 회복에 긍정적 효과를 나타냄을 시사한다 Western blot 분석에 의해 fisetin은 자외선 조사에 의해 활성화되는 p53의 수준을 유의한 수준으로 감소시키며 자외선 상해의 결과 세포주기의 정지에 수반되는 PCNA의 감소 경향을 다소 완화시켰다. 이러한 결과들은 fisetin이 DNA 회복의 활성을 통해 세포고사의 감소에 기여하며 이 과정에서 p53 및 PCNA의 수준변화와 관련하여 행동함을 시사한다. In the present study, we have investigated the effect of fisetin on the apoptosis and DNA single strand breaks in ultraviolet light B (UVB)-exposed NIH3T3 cells. Exposure of cells to UVB light $(200J/m^2)$ and post-incubation in growth medium for 48 hr resulted in about 50% of cells with apoptotic nuclear fragmentation. Addition of various concentrations of fisetin in the postincubation medium, however, significantly reduced the apoptotic nuclear fragmentation as compared with the values expected when the effects are additive and independent. DNA single strand breaks induced by UVB exposure were also significantly decreased by postincubation with fisetin. By Western blot analysis, fisetin post-incubation was shown to attenuate the p53 upregulation upon UVB exposure. Furthermore, the decrease of proliferating cell nuclear antigen (PCNA) level upon UVB exposure was alleviated by fisetin postincubation. These results suggest that fisetin decrease the apoptosis and increae DNA repair in a possible association with alteration of p53 and PCNA levels in UVB-exposed cells.

Ten species of Lycoris was selected for establishment of phylogenetic relationships using random amplified polymorphic DNA (RAPD) analysis, the native distribution and flowering characterestics. On the basis of the dendrogram constructed with the similarity coefficients, 10 Lycoris species were divided into two clusters. L. sprengeri and L. incannta were showed very high similarity in the RAPD analysis, same flowering time and flower color as pink. The leaf of L. squamigera. L. sanguinea, L. koreana, L. sprengeri and L. incanata emergenced in spring. The L. squamigera and L. sanguinea were showed high similarity in same cluster. Also L. koreana, L. sprengeri and L. incanata were showed high similarity in same cluster. The flower of L. radiata, L. radiata var pumila, L. albiflora and L. traubii was spider. These species was showed very low similarity in another Lycoris species. 본 연구에서는 RAPD 분석 기법과 자생지 분포와 개화특징을 이용한 유연관계를 분석하기 위하여 10종의 Lycoris 종을 선별하여 연구를 수행하였다. 10종의 상사화 종은 크게 두 군집으로 분류되었다. L. sprengeri와 L. incanata은 가장 높은 상동성을 보였으며, 같은 개화 시기와 분홍색의 화색을 가지고 있었다. 춘기출엽형은 L. squamigera, L. sanguinea, L. koreana, L. sprengeri 그리고 L. incanata이었으며, L. squamigera와 L. sanguinea는 같은 군집 안에서 높은 상동성을 보였다. 또한 L. koreana, L. sprengeri 그리고 L. sprengeri 그리고 L. incanata도 군집안에서 높은 상동성을 보였다. L. radiata, L. radiata var pumila, L. albiflora 그리고 L. traubii의 꽃은 spider형이며 이러한 종은 다른 종과의 유연관계가 매우 낮은 상동성을 보였다.
