본 연구에서는 개복숭아꽃과 흰색, 분홍색 매화 꽃의 항균 활성과 항산화, 미백 효과에 대해 알아보고자 하였다. 먼저, 3종의 꽃추출물들은 4종의 균주 중에 S. aureus에 대해 우수한 항균 활성을 나타냈다. 흰매화 클로로포름층은 0.5 mg/mL 농도에서 S. aureus에 대해 84%의 항균 활성을 보였고 개복숭아꽃과 분홍매화 클로로포름층도 0.5 mg/mL 농도에서 각각 49, 30%의 항균 효과를 나타냈다. 3종의 꽃추출물들은 P. aeruginosa에 대해서도 항균 효과를 보였다. 개복숭아꽃 클로로포름층과 분홍매화 클로로포름층은 0.5 mg/mL 농도에서 각각 36, 30%의 항균 활성을 보였다. 이 추출물들은 S. epidermidis와 E. coli에 대해서는 항균 활성을 보이지 않았다. 3종의 꽃추출물들은 HaCaT cell의 생존에 크게 영향을 미치지 않았다. 분홍매화 증류수층은 20, 40 ㎍/mL 농도에서 항산화 효과를 보였다. 분홍매화 에틸아세테이트층도 40 ㎍/mL에서 항산화 효과를 보였는데 이는 글루타치온 보다 우수하였다. 꽃추출물들은 B16F10 cell의 생존율에는 영향을 미치지 않았다. 꽃추출물들의 미백 효과는 개복숭아꽃 클로로포름층 40 ㎍/mL에서 18%가 나타났다. 이러한 결과들을 바탕으로 3종의 꽃추출물들은 항균 활성과 항산화, 미백 효과가 있는 원료로 판단할 수 있었다.

우리나라에서 노린재류는 여러 과수에 피해를 주는 해충이다. 우리는 핵과류 4종(매실, 체리, 자두, 복숭아)의 과실에 발생하는 노린재의 종류와 상대적인 풍부도를 2017년부터 2019년까지 3년에 걸쳐 조사하였다. 핵과류 과수원에서 과실에 발생하는 노린재는 가시노린재, 알락수염노린재, 썩덩나무노린재, 갈색날개노린재 등 4종이었다. 조사기간 중에 4종의 상대적인 풍부도는 썩덩나무노린재(65%), 갈색날개노린재(26%), 가시노린재(7%), 알락수염노린재(2%) 순이었다. 썩덩나무노린재는 매실, 체리, 복숭아에서 우점종이었던 반면, 자두에서는 갈색날개노린재가 가장 많이 발견되었다. 핵과류 과실에 발생하는 노린재는 성충이 81%이었고 약충이 19%이었다. 한편 핵과류 과종별 노린재의 발생은 생육초기보다는 생육후기에 더 많았다. 이상의 결과를 종합해 보면, 핵과류 과수원에서는 수확기에 썩덩나무노린재와 갈색날개노린재의 관리방안에 대한 전략이 개발되어야 할 것으로 보인다.

Viscum album var. coloratum (mistletoe) is considered as one of the endangered plant species in Korea. Our objective is to restore its population and multiplication of plant by ex situ method. In this research we explored the maximum germination (in vitro) of freshly harvested and stored seeds of mistletoe collected in different time intervals. Ex vitro germination after artificial inoculation on the branches of Prunus mume in different physiological conditions was also monitored. The research revealed that the lately harvested seeds (Feb. and March 2014) were superior over early harvested seeds (Nov. 2013 and Jan. 2014) of mistletoe due to the higher percentage of germination (above 93%). According to the data, it is also revealed that the survival and germination rate of mistletoe seeds decreased with the increase in storage duration. In ex vitro germination, the fluctuated temperature of a glass house in natural condition enhanced (four fold) the rate of germination on the branches of Prunus mume than the constant temperature condition in the glass house.

To select fruit trees suitable for shaded urban garden with Elaeagnus umbellata var. coreana, Malus domestica 'Alps Otome', Malus domestica 'Fujii', Prunus mume, Prunus persica for. persica, Rubus fructicosus, and Vaccinium corymbosum 'Reka', leaf growth in response to different light was investigated two years after 35% shade treatment. Leaf area of E. umbellata var. coreana, M. domestica 'Alps Otome', P. mume, P. persica for. persica, and V. corymbosum 'Reka' increased in shading. Fresh weight of leaves make inconsistent response to shading in every species but dry weight of E. umbellata var. coreana and P. persica for. persica showed the highest 150% and 148%, increment, respectively. Althought leaf water content of E. umbellata var. coreana decreased in shading, there is no difference in P. persica for. persica. Chlorophyll value of E. umbellata var. coreana and P. persica for. persica that showed higher than any other species is correlated with dark leaf green. Compared to specific leaf weight of E. umbellata var. coreana, P. persica for. persica, and V. corymbosum 'Reka' showed lower than any other species in shading, that of M. domestica 'Fujii', and R. fructicosus increased in reverse. These results indicate that E. umbellata var. coreana and P. persica for. persica that showed high value in several invesetigaton items are suitable for shady urban condition considering leaf growth in response to shading.

In order to get basic data for flood plain restoration, we surveyed the woody vegetation in Korean natural rivers and analyzed the species' characteristics with regards to patterns of richness and diversity. These characteristics were higher in hard wood forests than those in soft wood forests, such as Salix spp. community. Futhermore, they were the highest in the Prunus sargentii-Pinus densiflora community(H' 1.095), and the lowest in the Carpinus laxiflora community(H' 0.118) among the hard wood forests. Species' richness diversity were the highest in the Salix gracilistyla community, but the lowest in the S. koriyangi community or S. koreensis community among the soft wood forests. With regards to the dominant index, just one community is over 0.9, 13 communities are between 0.3-0.7 and 15 communities are less than 0.3. The Salix koreensis community was the highest at 0.931, and Prunus sargentii-Pinus densiflora community was the lowest at 0.13. Species' richness and diversity was significantly correlated with tree layer coverages and degree of slope. These results mean that in order to increase plant species diversity in flood plains planted hard woody trees, such as oaks and fir, are needed to suit environmental conditions with steeper slope and lower canopy coverage.

This study examined the changes in plant phenology of 12 woody species in Daegu University Forest, Gyeongsan-si, Gyeongsanbuk-do in 2007 and 2018. The Hobo was installed at a height of 1.2 meters to measure the microclimate such as air temperature and relative humidity to identify its effects on the changes in plant phenology. The number of trees surveyed were 42 individuals that included 12 species in 9 families, all of which are deciduous broad-leaved trees. The trends in temperature change in 2018 were similar to that in 2007, except for the temperatures in the warmest and coldest month. Compared to 2007, the average temperature of the warmest month in 2018 was $2.5^{\circ}C$ higher, and the coldest month was $3.3^{\circ}C$ lower. The lowest temperature from February to April in 2018 had the highest correlation with the blooming dates of the trees (r = 0.692) in 2018, and the highest temperature showed the lowest correlation (r = 0.392). The blooming date by species was significantly different (p < 0.05). The blooming date of 8 species (75%), including Prunus padus, was earlier by 1 to 16 days, while 4 species, such as Prunus armeniaca var. ansu, was later by 1 to 7 days in 2018 than that in 2007. However, the flowering duration did not have a significant effect on the plant phenology. The results can be used as basic data for long-term monitoring of plant phenology in the future, and follow-up studies on other environmental factors and physiological factors are needed.

본 연구는 2007년 3월부터 12월까지 충남대학교 부속사육장 및 전북 남원시 운봉읍 소재 가축유전자원시험장에서 수행하였다. 공시시료는 화본과목초(grasses)는 Lolium perenne, Festuca arundinacea, Poa pratensis, Agrostis alba 및 mixed grass의 5종과, 두과목초(legumes)는 Trifolium pratense, Medicago sativa, Trifolium repens, Melilotus officinalis 및 Vicia villosa의 5종, 수엽(browse)으로 Quercus serrata Thunb., Prunus jamasakura Sieb., Quercus aliena Blume, Robinia pseudoaccacia 및 Pinus densiflora의 5종과 잡초(weeds)는 Artemisia princeps Pampanini, Erigeron canadensis, Alopecurus aegualis Sobolewski, Echinochloa crusgalli var. frumentacea(Roxb.) Wight 및 Rumex crispus의 5종을, 야초(Weeds)는 Zoysia japonica Steudel, Agropyron tsukushiense var. transiens(HACK) Ohwi., Arundinella hirta(Thunb.) Tanaka, Miscanthus sinensis Anderss 및 Phragmites comunis Trin의 5종 등 총 25종을 공시하였다. 시험축은 꽃사슴(수컷) 5두를 공시하였으며, 평균체중은 92.5 kg이었다. 시료는 초종 당 건물기준으로 0.5 kg씩 급여하여 시험하였으로 시험결과는 다음과 같다. 공시시료의 조사료원별로 분석한 화학적 성분과 건물소화율은 대체적으로 채취장소, 초종, 생육단계 및 예취시기에 따라 차이를 보였다. 채식량, 채식비율 및 채식순위는 초종 및 수종에 따라 차이를 보였으며, 대체적으로 섬유소물질의 함량이 낮은 반면에 건물소화율이 높은 조사료를 더 즐겨 채식하는 양상을 나타내었다. 꽃사슴은 Quercus aliena Blume(갈참나무 잎, 500g)을 가장 즐겨 채식하였으며, 다음은 Prunus jamasakura Sieb.(벚나무 잎, 491g)과 Quercus serrata Thunb.(졸참나무 잎, 491g), Trifolium pratense(red clover, 481g) 순으로 즐겨 채식하였던 반면에, Phragmites comunis Trin(갈대, 8g)를 가장 적게 채식하였다. 꽃사슴의 채식습성은 수엽 36.5%, 두과목초 34.2%, 화본과목초 14.0%, 야초는 13.5% 및 잡초를 1.8% 채식하였던 것으로 보아 채식습성은 전형적인 수엽채식형(browser type)에 가깝다고 하겠다.
