원추리속(Genus Hemerocallis) 식물은 초본이며 일부 종은 약용으로 매우 중요하다. 이 속내 8개 분류군에 대해 ISSR (inter simple sequence repeats) 마커로 계통학적 관계를 분석하였다. 조사한 식물은 원추리(Hemerocallis fulva), 왕원추리(H. fulva for. kwanso), 각시원추리(H. dumortieri), 골잎원추리(H. coreana), 홍도원추리(H. hongdoensis), 큰원추리(H. middendorffi), 노랑원추리(H. thunbergii), 애기원추리(H. minor)이다. 또한 이들 분류군에 대한 유전적 변이와 구조를 조사하였다. 종간 유전적 다양도는 $0.068{\sim}0.123$이며 평균 유전적 다양도는 0.098로 전반적으로 낮았다. 애기원추리가 가장 높은 값을 나타내었다. 세대 당 이주하는 개체수는 매우 적었다(Nm=0.128). 원추리속 종은 계통도에서 세 분지군으로 나누어졌다. 한 그룹은 H. fulva, H. fulva for. kwanso, H. middendorffi였다. 다른 그룹은 Hemerocallis, H. dumortieri, H. thunbergii, H. minor였다. 나머지는 H. coreana와 H. hongdoensis로 두 번째 그룹과 자매군을 형성하였다. 비록 종 내 적은 개체수로 분석하였지만 원추리속 식물종이 ISSR 마커로 잘 분리되었다.

In July 2002, a destructive stem rot of tawny daylily(Hemerocallis fulva) was occurred sporadically in exhibition farm of Gyeongsangnam-do Agricultural Research and Extension Services located in Hamyang-gun, Korea. The fungus also caused collar and crown rot, and systemic wilt or blight of whole plant. White mycelium spread over stems and petioles of infected plants and sclerotia were formed on the old lesions and near the soil surface. The optimum temperature for mycelial growth and scierotial formations was $30^{\circ}C$ on PDA. The mycelial width ranged $4.2{\sim}10.4{\mu}m$ and the color was white, usually many narrow mycelial strand grew in the aerial mycelium and formed clamp connection. The shape of sclerotia was spherical and $1.0{\sim}3.2$ mm in diameter. The fungus was isolated repeatedly from the infected tissues and confirmed its pathogenicity to Hemerocallis fulva and identified as Sclerotium rolfsii. This is the first report on the stem rot of H. fulva caused by S. rolfsii in Korea.

This paper was conducted to acquire the scientific data for the waste landfill greening. The native plant flora was investigated in waste landfill at Nanjido. As a result, total 40 species, 22 families, 32 genus were classified. The dominant species were Robinia pseudoacacia (15%), Populus euramericana (3%), and Populus monilifera (1%), ect. Naive plant of 6 species (Zoysia japonica, Aster koraiensis, Liriope platyphylla, Hemerocallis fulva, Sedum kantschaticum, Indigofera pseudotinctoria) were planted in waste landfill in one species per 1 $m^2$ for greening purpose. After One year planting, the ornamental optimum value was showed in Zoysia japonica, Aster koraiensis, Hemerocallis fulva, Hemerocallis fulva, Sedum kantschaticum. The covering rate after nine months planting was 85% and 80% for Zoysia japonica and Hemerocallis fulva, respectively. While Aster koraiensis(a) 13 %, Liriope platyphylla 8 % and Sedum kantschaticum appeared 22 % were obtained. Aster koraiensis (a) has highest height and Sedum kantschaticum was the shortest plant.

Objectives : The amyloid $\beta$-protein ($A\beta$) is the principal component of the senile plaques characteristic of Alzheimer's disease (AD) and elicits a toxic effect on neurons in vitro and in vivo. Many environmental factors including antioxidants and proteoglycans modify $A{\beta}toxicity$. In this study, we have investigated the protective effects of water- and organic solvent-extracts of Hemerocallis fulva root fractions pre-extracted with methanol on $A\beta$-induced oxidative cell death in cultured rat pheochromocytoma (PC12) cells. Methods : For this study, we used MTT reduction assay for detection of protective effects of water- and organic solvent-extracts of Hemerocallis fulva root fractions pre-extracted with methanol on $A{\beta}_{25-35}$-induced cytotoxicity to PC12 cells. We also used cell-based $\beta$-secretase assay system to investigate the inhibitory effect of water- and organic solvent-extracts of Hemerocallis fulva root on $\beta$-secretase activity. Results : We previously reported that methanol extracts of Hemerocallis fulva root strongly attenuated cytotoxicity induced by the three $A\beta$ fragments ($A{\beta}_{25-35},\;A{\beta}_{1-42}\;A{\beta}_{1-43}$) to both SK-N-MC and PC12 cells. In the present study, we found that butanol-, ethylacetate-, chloroform-, and water-extracts of Hemerocallis fulva root fractions pre-extracted with methanol had strong protective effects against $A{\beta}_{25-35}$-induced cytotoxicity to PC12 cells and inhibitory potency to $\beta$-secretase activity. Conclusion : These results suggest that butanol-, ethylacetate-, chloroform-, and water-extracts of Hemerocallis fulva root fractions pre-extracted with methanol may contain the protective component(s) against $A\beta$-induced cell death in PC12 cells as well as inhibitory component(s) to $\beta$-secretase activity.

In March 2000, gray mold was found on day lily (Hemerocallis fulva L.) in Korea. Among the symptoms observed was blight or early rot with chlorotic halo of the leaves. All the isolates obtained from the lesions of the diseased plant parts were identified as Botrytis elliptica, based on the morphological characteristics of conidia. Conidia that formed on conidiogenous cells were not in chains, hyaline to pale brown, unicellular, ellipsoidal to obovate with a single hilum at the base, entirely verruculose, and 21-31 x 12-$23\mu\textrm{m}$ in size. Pathogenicity of the fungus was established by artificial inoculation on day lily plants. This is the first record of gray mold on day lily caused by B. elliptica in Korea.

나물자원의 수경재배시 양액농도가 생장 및 무기물함량에 미치는 영향을 조사하고자 벌개미취, 원추리 및 질경이를 펄라이트 배지에 추식하여 70일간 재배 한 후 생장정도와 무기물 함량을 분석하였다. 벌개미취와 원추리의 초장, 줄기직경, 잎의 수, 신선중 및 건물중은 1.5배액 처리구에서 확연하게 우수한 결과를 나타내었다. 질경이의 지상부와 지하부 생체중 및 건물중 등은 양액의 농도가 0.2재액에서 1.5배액으로 증가할수록 증가한 반면, 엽수와 근장은 0.5배액과 표준농도에서 가장 높은 것으로 나타났다. Ca Mg 및 Na 함유량은 벌개미취의 경우 1.5배액에서, 원추리와 질경이는 0.25배액에서 가장 많았다. K 함량은 벌개미취와 원추리는 0.5배액에서, 질경이는 1.5배액에서 가장 많았다. $P_2O_5$는 나물종류 및 양액의 농도에 따른 차이가 거의 없었다.

원추리속 식물은 초본류이며 이 속의 일부 종은 약용으로 중요하다. 이 속의 8개 분류군에 대해 엽록체의 rps16-trnK 부위로 계통관계를 평가하였다. 배당된 서열은 원추리(H. aurantiaca)에서 729 핵산 수로 가장 적었으며 왕원추리(H. fulva var. kwanso)에서 742 핵산 수로 가장 많았다. 그 차이는 염기 삽입에 기인하였다. 비록 일부 인델(indel)과 20개 염기의 삽입이 발견되었지만 서열 내 변이는 염기 치환이 많았다. rps16 - trnK에 의한 한국내 원추리속 분류군들은 높은 지지도로 잘 분리되었다. 애기원추리(H. minor)와 홍도원추리(H. littorea)는 높은 지지도로 같은 분지군을 형성하였으며 이 분지군은 노랑원원추리와 자매군을 형성하였다. 염색체의 수는 기존 보고된 RAPD의 결과와는 일치하지 않으나 본 연구와는 일치하였다.

The acid : alcohol combinations of the major wax esters were $C_{48}$: 22 : 26, 24 : 24, $C_{46}$: 22 : 24, and $C_{44}$: 22 : 22. This is the first report of l-monoacyl glycerols and friedelin from this plant. All isolates were identified on the basis of spectral data and chemical reactions.

The purpose of this study was to assess drought tolerance of groundcover plants for extensive green roof. Form July to November 2013, plant height, chlorophyll content, soil moisture, evapotranspiration and survival rate was measured. As results, after unirrigation started, Aster koraiensis reached 0% of soil moisture earliest followed by Sedum kamtschaticum, Hemerocallis fulva, Hylotelephium spectabile, Iris sanguinea, Hosta longipes and control. Among the plants, A. koraiensis withered earliest on 19th day of unirrigation experiment, followed by H. longipes and H. fulva (27th day); and I. sanguinea (29th day). S. kamtschaticum and H. spectabile survived even after 120th day of the experiment. As for chlorophyll content, I. sanguinea showed constant values in early stage than rapidly decreased right before its withering. Chlorophyll content of A. koraiensis and H. fulva showed rapid decrease from the beginning, while that of H. spectabile and S. kamtschaticum showed continuous reduction for first 30 days and the reduction was slowed down since then. In conclusion, H. longipes, I. sanguinea and H. fulva were found most applicable for extensive green roof considering scenic aspect.
