  • 자귀나무는 콩과에 속하며 우리 주변에서 훤히 관찰되는 나무로서 꽃, 잎, 열매 모두 관상 가치가 있다. 우리 고유수종인 본 나무는 수피는 한약재로도 사용되었고, 잎은 녹비로 사용하였으며 최근에는 조경수, 정원수, 가로수, 사방용수로 다양하게 사용되는 나무이다. 특히 꽃은 연분홍색의 공작새의 꼬리 같아 꽃피는 기간도 한 달간 지속되어 사람들의 사랑을 많이 받는 나무이다. 추위에는 비교적 약하지만 우리나라 전역의 공원 및 도시 주변의 조경수나 가로수로 적당한 수종이라 할 수 있다. 자귀나무는 비교적 병해충에 강한 수종으로 알려져 있으나 최근 몇몇 해충의 피해가 나타나 이들에 대한 생태 및 방제법을 간략하게 소개하고자 한다.

  • 바쁜 일상에 주위를 둘러볼 시간적 여유가 없는 도시인이라도 잠깐 눈을 돌려보면 주위에 다양한 식물들의 색다른 모습을 즐길 수 있다. 자귀나무는 가로수나 정원수로 많이 심지만 그리 많이 알려진 식물이 아니다 보니 그냥 지나치는 경우가 많다. 하지만 자귀나무에 대해 조금만 관심을 기울이면 그 매력에 푹 빠지게 된다.

  • Three bark extracts of Albizia julibrissin were prepared using water (AW), 70% (v/v) ethanol (AE), and hot water (AHW). Organic solvent fractions were analyzed for total flavonoids and polyphenols, antioxidant activities, and inhibitory activities against xanthine oxidase. Total flavonoid and polyphenol contents of the AHW extract were 8.57 mg/g and 108.67 mg/g, respectively. The SOD-like activities of all extracts, assayed at 1.0 mg/mL, were 10.46-16.73%. The nitrite-scavenging ability of the AHW extract, assayed at pH 1.2, was 60.82%, and the $IC_{50}$ value was $770.18\;{\mu}g$/mL. The electron-donating ability of the AHW extract, at 0.3 mg/mL, was 92.30%; the $IC_{50}$ values of the AW and AHW extracts were $31.31\;{\mu}g$/mL and $36.22\;{\mu}g$/mL, respectively; thus higher than that of ascorbic acid ($39.06\;{\mu}g$/mL). Xanthine oxidase inhibition by the AHW extract, at 1.0 mg/mL, was 94.05%. These results indicate that the AHW of A. julibrissin has potential as a natural antioxidant, for addition to foods and nutraceuticals.

  • In vitro culture system was established to induce multiple shoots of Albizzia julibrissin Duraz. by investigating the effects of cytokinins. Cotyledon, hypocotyl and root explants were cultured on MS media supplemented with either three different plant growth regulators or their combinations. The most effective cytokinin sources were zeatin 2.0 + TDZ 0.5 mg/L in cotyledon, zeatin 1.0 mg/L in hypocotyl, and BA 0.2 + TDZ 0.01 mg/L in root explant for producing shoots ($5.67\;{\pm}\;1.20$, $19.50\;{\pm}\;3.50$, and $20.50\;{\pm}\;2.47$, respectively). Also, zeatin treatment was tended to induce more shoots rather than the combinations of other cytokinins. In addition, the root induced in 1/2 MS medium without any plant growth regulators was longer and thicker than treatments of IBA, NAA, IAA and 2.4-D as auxins. Overall, the highest average percent of in vitro shoot formation was 73% from three different types of explants with treatment of zeatin (1.0mg/L).

  • In the present paper, we intented to analyze and to compare the different seed dormancy of two legume plants, Albizzia and Cercis. We found two different types of seed dormancy: one type of dormancy in Albizzia seed was caused by the water impermeability, and other type of seed dormancy was found in Cercis and it was induced by inhibitors. We confirmed that the extract substances from Cercis seed seemed to have strong regulational functions on the inhibition of seed germination and primary root growth of lettuce seed.

  • To investigate the vegetation structure of mountain region from Wolgagsan to Dogabjae, 14 plots($2000m^2$) set up with random sampling method were surveyed. Two groups of Quercus variabilis-Pinus densiflora community, Quercus mongolica-Quercus acutissima community were classified by cluster analysis. Quercus variabilis, Pinus densiflora, Quercus mongolica, Quercus acutissima, Quercus dentata and Quercus serrata were found as a major woody plant species in Weolchulsan National Park region. In this area, Quercus variabilis and Pinus densiflora were dominated partially. In the future, the importance percentage of Pinus densiflora might be decreased, but those of Quercus variabilis, Quercus mongolica, Quercus acutissima and Quercus dentata might be increased. High positive correlations was proved between Quercus variabilis and Pinus rigida; Styrax japonica and Quercus dentata, Quercus acutissima; Pinus rigida and Lindera erythrocarpa, Pinus densiflora; Lindera obtusiloba and Rhododendron mucronulatum; Albizzia julibrissin and Styrax obassia, and relatively high negative correlations was proved between Diospyros kaki and Quercus dentata; Platycarya strobilacea and Lindera erythrocarpa; Symplocos chinensis for. pilosa and Quercus acutissima; Styrax japonica and Styrax obassia; Pinus rigida and Lindera obtusiloba, Fraxinus sieboldiana, Rhododendron mucronulatum; Quercus mongolica and Albizzia julibrissin. Species diversity(H') of investigated groups was ranged $1.2430{\sim}1.2892$.

  • This research analyzed useful nutritional component data in stems and leaves of the Albizzia julibrissin for proximate composition, contents of soluble protein, reducing sugar, free sugar, total polyphenol compound, mineral, free amino acid, and amino acid derivative. The carbohydrate contents of A. julibrissin stems and leaves were 71.08% and 64.85%, and crude protein contents were 8.05% and 11.38%, respectively. In addition, the crude fat contents were 2.95% and 3.03%, and the crude ash contents were 8.98% and 9.07%, respectively. Reducing sugar and free sugar in stems were 711.80 mg% and 15.66 mg%, and 1,422.83 mg% and 40.3 mg% in leaves, respectively. The contents of soluble protein were 229.57 mg% in stems and 1,073.59 mg% in leaves. The polyphenol and flavonoid compounds were 446.67 mg% and 16.36 mg% in stems, and 2,583.33 mg% and 2,234.75 mg% in leaves. In the results of mineral analysis, the content of Ca was the highest in stems as 933.07 mg% followed by K (605.07 mg%). The content of K was also the highest (1,489.53 mg%) in leaves, and Ca was 287.73 mg%. The free amino acid content of A. julibrissin stems was 2,977.28 mg%, and 8,840.66 mg% in leaves. Total contents of amino acid derivative were 263.53 mg% in stems and 696.47 mg% in leaves.
