DPPH radical-generating system was used to evaluate the antioxidant properties of the Rosaceae. The inhibitory effects of ethanolic extracts from Rosaceae plants were investigated on melanin biosynthesis which is closely related to hyperpigmentation. Of the Rosaceae extracts, Prunus sargentii, Rubus coreanus, Chaenomeles sinensis, Photinia glabra and Pyrus pyrifolia showed a potent inhibition of tyrosinase, the enzyme which converts 3-(3,4-dihydroxyphenyl) alanine (dopa) to dopachrome in the melanin biosynthetic process. Furthermore, MMT assay was used to check the cytotoxicity of extracts on the human foreskin fibroblast cell line, Hs68. Among the Rosaceae, bark of Prunus sargentii, bark wood of Photinia glabra and all parts or Chaenomeles sinensis showed more than $50\%$ inhibition of mushroom tyrosinase activity at 100 ug/mL and more than $80\%$ of strong DPPH radical-scavenging activity at 10 ug/mL. In audition to, they had no cytotoxic activity on Hs68. These results suggest that these extracts might be except a controler in pigmentation.

Perforated ray cells are recorded for the first time in the Korean hardwoods of Rosa multiflora, Rosa multiflora var. platyphylla, Rosa rugosa, Spiraea cantoniensis, and Stephanandra incisa belonging to the family Rosaceae. The perforated ray cells have simple perforations, which are identical with the types of perforation plates in the vessel elements of same wood.

꽃을 우려내어 차로 마시는 꽃차(flower tea)는 꽃이 가진 색과 향, 맛과 모양을 즐길 수 있어 최근 수요가 급증하고 있다. 본 연구는 매화(Prunus mume), 장미(Rosa spp.), 그리고 해당화(Rosa rugosa) 등 3종의 장미과 식물의 꽃차의 향기 성분 특성을 구명코자 꽃차를 headspace vial에 담은 후 solid phase microextraction(SPME)를 이용하여 추출한 후 gas chromatography-mass spectrometry를 이용하여 휘발성 성분을 분리하였다. 분리된 각 성분은 deconvolution 과정을 수행한 후 NIST masss spectral library를 이용하여 동정하였다. 매화꽃차에서는 총 58개의 휘발성 성분이 검출되었는데, benzaldehye와 nonane, 그리고 phenylmethanol이 주요 구성 성분으로 검출된 전체 휘발성 성분의 각각 64.7%, 16.1% 및 4.7%를 차지하고 있었다. 장미 꽃차의 경우 검출된 35종 중 주요 구성 성분은 nonane과 2-phenylethanol, 그리고 phenylmethanol로서 각각 전체 성분 중 54.0%, 18.0% 및 4.6%를 구성하고 있었다. 해당화 꽃차의 경우는 장미 꽃차와 동일하게 2-phenylethanol(62.2%)과 nonane(20.1%)이 주요 성분으로 동정되었으며 이들 2 성분의 합이 전체 43개 휘발성 성분의 82.3%를 차지하는 것으로 나타났다. 본 연구에 사용된 매화, 장미, 해당화 등 장미과 식물 3종의 꽃차 모두에서 공통적으로 검출된 휘발성 성분은 앞서 각 꽃차 종류별 주요 성분으로 언급된 4종의 성분을 포함하여 19종이었으며 매화꽃차에서만 검출된 성분은 29종으로 장미꽃차(6종)와 해당화 꽃차(8종)보다 향기성분의 다양성이 높은 것으로 나타났다.

본 연구에서는 향이 자율신경계에 미치는 영향을 알아보고자 100%의 Rose oil bulgarian, Lemon oil misitano, Jasmin abs., Lavender oil france (KIMEX co. Ltd)의 네가지 향을 사용하여 심전도, 피부온도, 피부저항의 생리신호를 측정하였고, 생리신호의 측정과 함께 주관적 설문지의 평가를 통해 생리신호와의 상관성을 살펴보았다. 주관적 평가 중 양극 척도의 긴장/이완에 해당되는 문항의 분석결과 장미>자스민>레몬>라벤더 순으로 피험자들에 의해 장미가 가장 긴장된다는 결과를 나타냈다. 향의 선호도 조사에서는 장미향이 가장 진한 향으로 레몬 향이 가장 좋은 향으로 분석결과가 나왔다. 생리신호 중 평균 R-R 간격의 측정 결과는 장미향에서 가장 긴장도가 높게 나타났으며 이에 따른 주관적 평가 결과 역시 장미향이 긴장도가 높게 나와 생리신호와 주관적 평가의 결과가 상관성을 가지고 있음을 알 수 있었고, 피부온도 결과에서는 평균 R-R 간격에서 긴장도가 가장 높은 장미가 피부온도가 가장 높게 나왔다. 피부저항은 레몬 향이 가장 긴장된 것으로 나온 반면 라벤더가 가장 이완으로 나타났으며 라벤더의 경우 주관적 평가와의 상관성을 가짐을 알 수 있었다. 이와 같이 향이 자율신경계에 미치는 영향을 알아보고자 주관적 평가와 생리신호를 동시에 측정하였는데 그 결과 주관적 평가와 생리신호의 상관성을 통해 향이 자율신경계에 어떤 영향을 미치는가를 알 수가 있었다.

We report an unrecorded species of the genus Sorbaria (Rosaceae) in Korea, namely Sorbaria kirilowii (Regel & Tiling) Maxim. This plant was discovered both on Pocheon-si, Naecheon-myeon and Yeoju-gun, Buknae-myeon in Gyeonggi Province. It is distinguishable from Sorbaria sorbifolia (L.) A. Braun var. stellipila Maxim. by characteristics such as presence of hair on leaf and rachis, morphology of inflorescence, length and width of petal, shape of sepal, number and length of stamens, presence of hair upon and size of follicles. This taxon was given the Korean common name 'Jom-swi-ttang-na-mu' based on the small size of floral characters.

Pine (Pinus densiflora) forests of 58 sites on the ridge of the Baekdudaegan, South Korea were classified by applying the phytosociological method and TWINSPAN. The floristic composition and life-form characteristics of the vegetation types analyzed and documented. The vegetation types were classified into five groups including four groups of Carex humilis var nana type and one group of Abies koreana-Sasa borealis type. Compositae was the most diverse family (26 species), Liliaceae (21 species), Rosaceae (18 species) and Betulaceae (11 species) whereas 27 families were represented by only one species. Taxonomically, Compositae was the most diverse (17 genera), Liliaceae and Rosaceae(12 genera) whereas 41 families were represented by only one genus. The Fagaceae was the most important family in total coverage (19.0) and followed Pinaceae (16.7) and Ericaceae (15.1). Five families such as Compositae, Liliaceae, Rosaceae, Betulaceae, and Umbelliferae contributed little to total coverage, although represented by numerous species. In the correlation between species richness and life forms, the species richness was highly correlated with growth and disseminule forms. In general, the correlation coefficients between life forms represented lower values than those between species richness and life-forms.

The fire blight caused by Erwinia amylovora (Ea) is a devastating disease of Rosaceae plants, including commercially important apple and pear trees. Since the first report in Korea in May 2015, it has been spreading to neighboring regions gradually. Host plants can be infected by pollinators like bees, rainfall accompanied by wind, and cultural practices such as pruning. Many studies have revealed that wild Rosaceae plants such as Cotoneaster spp., Crataegus spp., Pyracantha spp., Prunus spp., and Sorbus spp. can be reservoirs of Ea in nature. However, wild Rosaceae plants in Korea have not been examined yet whether they are susceptible to fire blight. Therefore, the susceptibility to fire blight was examined with 25 species in 10 genera of wild Rosaceae plants, which were collected during 2020-2022, by artificial inoculation. Bacterial suspension (10⁸ cfu/ml) of Ea type strain TS3128 was inoculated artificially in flowers, leaves, stems, and fruits of each plant species, and development of disease symptoms were monitored. Moreover, the presence of Ea bacteria from inoculated samples were checked by conventional polymerase chain reaction. Total 14 species of wild Rosaceae plants showed disease symptoms of fire blight, and Ea bacteria were detected inside of inoculated plant parts. These results suggest that wild Rosaceae plants growing nearby commercial apple and pear orchards in Korea can be Ea reservoirs, and thus they should be monitored regularly to minimize the damage by Ea infection and spreading.
