  • 비짜루과 둥굴레속(Asparagaceae: Polygonatum)은 전 세계적으로 약 90여 종이 알려져 있으며, 유럽, 북아메리카, 아시아 등 북반구 온대 지역에 집중적으로 분포한다. 국내 둥굴레속 분류군은 총 16분류군이며, 이중 잎이 호생하고, 난형에서 타원형 모양의 엽질성 포를 가지며, 화피통 내부에 털이 없고, 수술대 표면에 돌기가 나있는 분류군들은 용둥굴레열(series. Bracteata)에 속한다. 그러나 이들은 종간 교잡 또는 주요 기관의 형질 변이가 다양하여 중간형질을 보이는 개체군들에 대한 종 식별에 많은 어려움이 있었다. 경남 창원시에서 채집된 목포용둥굴레(P. cryptanthum) 변이 개체집단는 기존의 목포용둥굴레와 달리 식물체 높이와 화경·소화경이 길며, 포 부착위치의 변이 폭이 넓으며, 포가 타원형이고 밖으로 말리는 습성으로 형태적 차이가 나타났다. 따라서 본 연구에서는 명확한 분류학적 실체를 구명하고자 분자생물학적 계통분석(nrDNA ITS + cpDNA matK, trnK-rps16, rps16, rbcL) 연구를 진행중에 있다.

  • The Polygonatum spp. used in this study was collected from 1994 to 1997, and planted by species in Hamyang medicinal plant experimental station field. $30{\sim}40 $ species of Polygonatum spp. have been known to be distributed in the northern hemisphere, and $14{\sim}18$ species in Korea. In this study, collected seven species of Polygonatum spp. were investigated. Plant height was highest in Polygonatum stenophyllum followed by P. falcatum, P. humile, P. lasianthum var. coreanum.. Leaf length was longest in P. falcatum and shortest in P. odoratum and leaf width was the most wide in P. odoratum var. pluriflorum. P. stenophyllum had 111 flowers per stem. The other species had $14{\sim}22$ flowers per stem. The ratio of flower setting in each species was high at two but was 95.2% at above four in P. stenophyllum. The number of fruits was 14.8, 15.4 and 17.7 in P. odoratum, P. falcatum and P. humile, respectively. Other species did not produce fruit. Fruit setting percentage was high in P. odoratum as 81.5%. The number of branched rhizome doubled every year.

  • This study was done to accept basic data on chemical components in rhizome of native Polygonatum species in Korea. In mineral contents of their rhizome, total nitrogen, potassium, calcium, magnesium and sodium concentration were higher in Polygonatum inflatum, P. humile and P. odoratum var. pluriflorum 1 than the other species in all the sampling dates. P. odoratum var. pluriflorum 1, P. odoratum var. pluriflorum 2 and P. inflatum showed relatively higher iron and mananese contents but P. odoratum var. pluriflorum 1 and P. stenophyllum did in copper content on November 20. Total sugar was acculated in later growth stages, although P. stenophyllum had the highest content but P. lasianthum var. coreanum had the lowest in all the sampling dates. Protein content was the highest in P. lasianthum var. coreanum but the lowest in P. stenophyllum in all the sampling dates. The major amino acids in their rhizomes were arginine followed by glutamic acid, and total and essential amino acid content were abundant in P. lasianthum var. coreanum and P. humile.

  • Morphological characteristics and growth pattern of 10 Polygonatum collections indigenous to Korea were examined to select the promising medicinal, edible resources and horticultural crops. Plant heights of I0 collections ranged from 15 to 102cm. Stem type was ascending or erect, and node numbers per a stem was 6.2 to 23.2. Phyllotaxis type was alternate or verticillate, and leaf shape was elliptical or linear. Leave numbers per a stem was 5.2 to 63.4, and bract types were classified into bracteate and nonbracteate. Flowers bloomed from May 7 to May 30, and flowering period was 5 to 13 days. Inflorescence types were classified into racemose, corymbose, and umbellate. Flower numbers per a stem was 1.5 to 125.2, and flower length was 13.1 to 30.2㎜. Perianth shapes were classified into tubular, constrict and urceolate. Surface colors of rhizome were pale yellow, pale brown, brown, and dark brown. As a result of this experiment, P. sibiricum, P. odoratum var. pluriflorum and P. odoratum var. thunbergii were thought to be useful as the medicinal and edible resources plants. On the other hand, P. odoratum var. pluriflorum 'Variegata', and P. odoratum var. maximowiczii, P. lasianthum. P. involucratum, P. desoulavyi, P. humile, and P. inflatum were thought to be useful as horticultural plants.

  • The sequence data of the plastid DNA (trnL-F IGS, trnL intron, and trnH-psbA) and nuclear DNA (RNApol2_i23) markers were utilized to study phylogenetic relationships among the taxa in the Polygonatum odoratum complex (Ruscaceae). European P. odoratum individuals form a clade with a high bootstrap value, which is a sister to the clade of Korean P. odoratum var. odoratum, P. odoratum var. pluriflorum and P. robustum. The formation of the clade with P. odoratum var. odoratum, P. robustum, and one accession of P. odoratum var. pluriflorum indicates geological speciation in isolated populations in the islands following dispersal events from the mainlands. All data sets form two major clades, which are congruent with the subgroups divided by the basic chromosome numbers (x = 9 and x = 10). Although it is not easy to test the hypothesis of the decrease in the basic chromosome number due to scatter taxon sampling in this study, the molecular data strongly suggested that aneuploidy plays an important role in lineage diversification in the genus Polygonatum. The cytological data was not strongly supported by the cpDNA sequences. Further investigations of the cytological, morphological, and geographical characteristics with comprehensive sampling are desired to understand the evolution and lineage diversification in the genus.

  • Two herbal medicines of the Polygonatum genus, namely Polygonati Rhizoma and Polygonati Odorati Rhizoma, are difficult to distinguish from each other through exterior morphologic aspects. Furthermore, because the standard components for physiochemical distinction have not yet been standardized, the identification of these medicines through botanic taxology is based on genetic methods of random amplified microsatellite polymorphism (RAMP). For the RAMP evaluation, we used five sets of UBC microsatellite primers 811, 818, 834, 836, 842 and random primer M1. Although no specific band that could clearly distinguish Polygonati Rhizoma from Polygonati Odorati Rhizoma was found, 11 Polygonatum plants could be divided into two groups by this method. P. sibiricum and P. stenophyllum were classified to group I and the others were to group II. As P. sibiricum and P. stenophyllum were very similar in genetic and morphologic perspective, the results suggest that P. stenophyllum belongs to the Polygonati Rhizoma family.
