송정호,박문한,한상억,이위영,박완근,이재선,Song, Jeong-Ho,Park, Mun-Han,Han, Sang-Urk,Lee, Wi-Young,Park, Wan-Geun,Yi, Jae-Seon 한국산림과학회 2001 한국산림과학회지 Vol.90 No.4
굴참나무 동아의 형태적 변이를 연구하기 위하여 위도, 경도, 해발고 및 지리적 특성을 고려하여 16개 천연집단을 선발하였다. 각 집단별로 30개체를 대상으로 개체목당 수관 1/3 하단부에서 정아와 측아를 30개씩 고르게 채집하여 정아와 측아의 길이 및 폭에 대한 변이를 조사한 결과는 다음과 같다. 1. 정아길이, 정아폭, 측아길이 및 측아폭은 각각 6.9~11.3cm, 3.0~3.7cm, 6.1~8.9cm 및 2.5~3.1cm로 나타났으며, 모든 특성에서 약 20% 내외의 변이폭을 보였다. 2. 동아특성에 대한 변이는 집단간 및 집단내의 개체간에 고도의 유의적인 차이를 보였으며 특히, 분산기여도는 집단간보다 집단내의 개체간에 큰 것으로 나타났다. 3. 상관분석한 결과 정아길이는 측아걸이 및 폭과, 측아폭은 정아폭 및 측아길이와 정의 상관을 나타내었으며, 또한 지리적 변이에 있어 위도는 정아폭과, 경도는 정아길이 및 측아길이와 정의 상관을 나타내었다. 4. 군집분석한 결과는 거리지수 3.4에서 2개의 그룹 즉, I그룹(Pop. 8)과 II그룹(Pop. 1, 2, 3, 4, 5, 6, 7, 9, 10, 11, 12, 13, 14, 15, 16)으로 나뉘었으며, 거리지수 1.5에서는 II그룹이 다시 Pop. 1, 2, 7, 9, 및 11의 군집(II-1그룹)과 Pop. 3, 4, 5, 6, 10, 12, 13, 14, 15 및 16의 군집(II-2그룹)으로 나뉘어 거리지수 1.2 이상에서 총 III그룹으로 분리되었다. For the study of morphological variation in winter buds of Q. variabilis $B_L$. natural populations in Korea, 16 populations were selected through the country in consideration of latitude, longitude, altitude, and geographical characters. Thirty trees were randomly selected from each population and 30 terminal and 30 lateral buds were sampled below 1/3 crown length of each tree. Four morphological characters including length and width of terminal and lateral buds were measured. 1. Length and width of terminal and lateral buds were in the ranges 6.9~11.3cm, 3.0~3.7cm, 6.1~8.9cm, and 2.5~3.1cm, respectively. The coefficient of variation were in about 20% in all the characters investigated. 2. All the characters were significantly different among populations as well as among individuals within populations. The degree of contribution of variance among individuals within populations was higher than that among populations. 3. Length of terminal bud showed positive correlation with length and width of lateral bud; and width of lateral bud with width of terminal bud and length of lateral bud. Also, positive correlations were observed between longitude and width of terminal bud, between latitude and length of terminal and lateral bud. 4. Cluster analysis using complete linkage method for winter bud characters showed two groups to Euclidean distance 3.4. They were group I of population 8 and group II of populations 1, 2, 3, 4, 5, 6, 7, 9, 10, 11, 12, 13, 14, 15, and 16. However, group II was divided into two at Euclidean distance 1.5 that are a group including populations 1, 2, 7, 9, and 11(groupII-1) and the other group including populations 3, 4, 5, 6, 10, 12, 13, 14, 15, and 16(groupII-2).

This study was carried out to analyze the nutritional composition, bioactive compound and antioxidant activity in fresh sprout of 3 new Kalopanax septemlobus cultivars. Cheong-San, Cheong-Song and Cheong Sun 1 had largest carbohydrate (52.90, 53.12, 55.28%), crude protein (34.23, 31.33, 33.58%) in the proximate composition and had largest K (2.29, 2.22, 2.23%) followed by Ca (0.44, 0.34, 0.37%), Mg (0.24, 0.19, 0.19%) in the mineral contents. Three new cultivars contained a total of 26, 25 and 28 different kinds of amino acids, respectively and the number of essential amino acid is 6, 6 and 7 species, respectively. Also, Cheong-San had higher total polyphenol contents and Cheong-Song had higher total flavonoid contents. DPPH free radical scavenging activity of 70% ethanol, water extracts of Cheong-San and Cheong-Song is higher than others at 100 ppm. In the ABTS radical cation decolorization activity, 70% ethanol extract of Cheong Sun 1, water extract of Cheong-San and Cheong-Song are higher activity than others and all samples have more than 85% ABTS racial cation decolorization activity at 500 ppm. Our results suggest that new K. septemlobus cultivars possess good antioxidant capacities with a high nutritional value and might have potential applications in the food and medical industries.
