Polyacrylamide gel 전기영동법(電気泳動法)을 이용(利用)하여, 슬래쉬 소나무 (접목묘(接木苗), 20년생(年生))의 화아원기형성기간(花芽原基形成期間) 동안에 자화다량(雌花多量) 개화개체(開花個体)와 소량(少量) 개화개체간(開花個体間)에 정아(頂芽)의 peroxidase 동위효소(同位酵素)의 변화(変化)를 비교(比較)하였다. 정아(頂芽)에서 모두 9개의 band를 관측(観察)할 수 있었으며, 두 개체간(個体間)에 동위효소(同位酵素)의 양적(量的)인 차이(差異)는 미세(溦細)하였으나, 제오(第五) band는 다량(多量) 개화개체(開花個体)에서 대부분(大部分) 발견(発見)되었다. 제오(第五) band의 동위효소(同位酵素)는 자화원기형성(雌花原基形成)에 직접(直接) 관병(関聠)되는 것 같이 생각된다.

A study was designed to investigate the pattern of sexual dimorphism in a plantation of Garcinia kola. Twenty trees were randomly selected for the study and have been observed to flower regularly. A total of 100 inflorescence were randomly collected from the crown of each tree and 500 flowers randomly assessed within the period of four (4) flowering seasons. Floral sex assessment was done visually and with a hand magnifying lens; floral morphometric measurements (i.e. pedicel and perianth length and breadth), inflorescence length, and breadth) was taken using a veneer caliper; number of flowers per inflorescence and inflorescence per twig was counted; while, data analysis was conducted on excel using analysis of variance and pairwise t-test comparison. Four floral sexes were identified in the G. kola plantation studied which were unisexual male flowers, unisexual female flowers, cosexual unisexual male flowers, and cosexual hermaphrodite flowers. Three tree sexes were identified viz: inconstant male, invariant female, and cosexual trees. The plantation was significantly sexually dimorphic in floral sex and phenotypic traits (i.e. pedicel and perianth size), and as well as sexually dimorphic in tree sex and reproductive phenotypic traits (i.e. inflorescence size, number of inflorescences per twig, and number of flower bud per inflorescence). The sexual system of the plantation was therefore trioecious with features suggestive of evolving dioecy through the gynodioecious pathway.

본 연구는 기능성 성분으로 알려져 있는 게르마늄을 '신고' 배나무에 처리 방법을 달리 했을 때 어떤 처리방법이 동계전정 된 가지에 게르마늄 흡수를 증가시키며 화아형성에 기여하는지에 대해서 조사하였다. 게르마늄 처리는 엽면살포, 토양 내 관주, 수간주입, 그리고 세가지 복합처리를 포함하였다. 전정 된 가지 내 게르마늄 함량은 복합처리구에서 가장 높았으며 게르마늄 처리 모두 대조구 보다 높은 함량을 보였다. 수삽된 전정가지 당 눈의 중량과 발생 된 인편의 수는 게르마늄 처리구에서 대조구보다 높은 경향을 나타냈다. 게르마늄 처리구는 개화율과 화총 당 꽃수를 증가시켰으며 저온 피해에 대해 대조구보다 유의적으로 낮은 양상을 보였다. 전체적으로 게르마늄 처리방법에 따른 수체에 나타나는 효과는 일관성이 없었다.

Background and objective: Native to the limestone zones of the Korean Peninsula, Zabelia tyaihyonii is a popular plant for landscaping. As it is now classified as a rare species, the conservation of its genetic resources is necessary. Methods: In this study, which aimed to understand the morphological variation of Z. tyaihyonii, 18 characteristics of Z. tyaihyonii from five habitats were examined. Results: Of these 18 characteristics, 16 characteristics showed significant differences among sites, and the coefficient of variation ranged from 5.4% (for corolla lobe number) to 31.3% (for flower number). Notable variations were observed in the size of flower and calyx lobe. When the corolla length and calyx lobe length were used as the classification key of Z. tyaihyonii, the sites were divided into those with small, intermediate, and large values. Hair was observed on the filament of all samples, a finding which conflicts with an earlier report. Rather than classifying Z. tyaihyonii into different species on the basis of corolla length (COL) and calyx lobe length (CALL) values, we recommend modifying the species description to incorporate the variation in these characteristics of interest. Principal component analysis results showed that the first main component was highly correlated with the traits related to the size of the calyx lobe (length: 0.819, width: 0.758), and the second main component was highly correlated with the traits related with the size of the inflorescence (length: 0.790, width: 0.626). Conclusion: Several notable variations were identified among the characteristics related to inflorescence and calyx lobe. There is little genetic exchange among groups, or each group is influenced by micro environmental factors, because sites that are located nearby. In addition, the difference between COL and CALL, which is used as the classification key for Z. tyaihyonii, was divided into small group, large group, and intermediate group, regardless of the sites' geographical distance.

This study analyzes the characteristics of the motifs and colors in flower and bird paintings which contain and present Korea's unique aesthetics based on its richest data among all other types of Korean folk paintings. With a theoretical exploration of folk paintings and an analysis of the motifs and colors, textile design with an aim to present highly valued korean modern fashion design was developed. Two hundred and seventy flower and bird paintings were selected from relevant materials, resulting in an extraction of 5,068 colors. A palette of representative colors was made based on densely distributed hues and tones. The research can be summarized as follows: Flower and bird paintings contain flowers, birds, trees and animals and the motifs in the paintings stand for spirituality, philosophies from different times and other symbols of our nation. Each of the motifs in these paintings is a prayer for good luck, especially conjugal harmony and fecundity to bring about happiness and richness. Colors in flower and bird paintings are characteristic of the order: YR(25.5%)>R(19.2%)>Y(10.6%)>PB(9.2%)>G(7.9%), with low-chromatic YR and highly bright R taking up a larger percent. The order of tones is: d(13.5%)>dk (10.5%)>s(10.4%)>dkg(10.0%)>sf(9.1%)and the tone is dark in general. YR, taking up the largest percent, was dull, light, and soft. As for the achromatic colors, the order is: W(5.2%)>Gy(1.9%)>Bk(0.7%). Based on the above analyzed color data, those colors which were high in their hue and tone were extracted to present representative colors. In this way, representative colors like yellow, yellowish red, red, green, and purplish blue were extracted. This was the basis to present motifs and colors originating from subjects of folk paintings in various patterns using Illustrator CS6, to create modern fashion design.

본 연구는 감꽃의 주요 향기성분을 알아보기 위해서 감나무 수령별로 감꽃의 향기성분을 SPME를 이용하여 분석하고, 기관을 꽃과 꽃받침으로 분류하여 향기성분을 비교하였다. 감나무 수령별 감꽃의 만개율은 15년생 이상, 10-14년생, 5-9년생 순으로 수령이 오래될수록 초기 만개율이 높았다. 감나무 수령에 따른 감꽃 향기성분 분석 시 동정된 주요 향기 성분은 a-pinene, butene, caryophyllene, cubebene, lavandulol, D-limoneneylangene, ylangene 등의 성분을 얻을 수 있었다. 대부분이 green향, fruit계, floral계의 옅은 향도 포함하고 있었다. 감꽃에 존재하는 휘발성 향기성분의 수는 5-9년생은 30종, 10-14년생은 24종, 그리고 15년생 이상에서는 32종으로 수령이 5년 미만과 15년 이상에서 많은 향기성분이 조사되었다. 감꽃을 꽃받침과 나누어 향기성분을 비교하면 단감 '부유' 품종 중 꽃의 향기 성분은 10개이고 상대적인 총 함량은 26.35%이며, 꽃받침은 향기 성분은 14개이고 상대적인 총 함량은 46.28%로 꽃에 비해서 더 다양한 향기성분이 존재하는 것으로 조사되었다. 반면 떫은감 '둥시' 품종은 꽃에서는 6개의 향기성분이 17.58%, 꽃받침에서는 9개의 향기 성분이 50.27%로, '부유' 품종에 좀더 다양한 향기성분이 존재하였다. 본 연구는 감꽃 향기를 이용하고자 하는 향기산업에 기초자료를 제공하는데 기여할 것이다.
