  • 산꼬리풀(Veronica rotunda var. subintegra T.Yamaz.)은 다년생 초본류로 달성이라는 꽃말을 가진 우리나라에만 자생하는 특산식물이다. 줄기는 곧게 서며, 줄기 끝에 보라색의 꽃이 총상화서로 피어 관상가치도 우수하다. 또한, 전초를 일지향이라 불리우며, 중약대사전에는 천식과 기침, 감기, 기관지염 등에 효능이 있다고 보고되었다. 이러한 산꼬리풀의 육묘 체계의 확립을 위하여 2017년 6월 2일부터 7월 31일까지 약 8주간 육묘하였다. 종자 육묘기술 개발을 위한 공통조건은 200구 트레이에 원예상토를 충진한 다음 셀 당 4립씩 파종하여 55% 차광막이 설치된 배드에 배치하였으며, 이후 4, 6주차에 Hyponex $500mg{\cdot}L^{-1}$을 처리하였다. 토양실험은 원예상토 단용[$300-200-200mg{\cdot}L^{-1}$(N-P-K)], 피트모스:펄라이트(3:1) 및 코코피트:펄라이트(3:1) 혼용토를 사용하였다. 피트모스와 코코피트의 혼용토는 원예상토의 비료농도를 기준으로 0-0-0, 300-200-200, $600-400-400mg{\cdot}L^{-1}$의 비료를 첨가하였다. 파종 립수별 실험은 셀탕 1, 2, 4 및 6립으로 하였으며, 추비는 hyponex(6.5-6-19) 0, 500, $1000mg{\cdot}L^{-1}$를 증류수에 희석하여 2회 분무기로 살포하였다. 차광 실험은 0, 55, 75% 등의 차광막이 설치된 곳에서 수행하였다. 연구의 결과, 산꼬리풀의 육묘는 원예상토를 사용하는 것이 다른 토양에 비해 우수한 결과를 보였다. 초장, 경직경 및 엽수는 원예상토를 이용하는 것이 가장 효과적이었으며, 다음으로 피트모스:펄라이트 혼용토 순이었다. 근장의 경우, 피트모스 혼용토에서 비료 농도와 관계없이 원예상토에 비해 유의적으로 길었다. 파종립수에 따른 초장과 경직경은 1, 2립 파종구에서 가장 양호하였으며, 파종량이 적을수록 길고 굵어지는 경향이었다. 엽수도 셀 당 파종량이 적을수록 많아지는 경향이었으나, 유의적인 큰 차이는 확인되지 않았다. 추비는 지상부의 경우 hyponex $500mg{\cdot}L^{-1}$ 처리 시 생육의 증가 효과가 있었지만, 비교적 고농도인 $1000mg{\cdot}L^{-1}$ 처리구에서는 생육에 효과가 없거나 억제되는 결과를 보였다. 한편, 근장은 처리농도가 높을수록 증가하는 경향이었고, hyponex $1000mg{\cdot}L^{-1}$ 처리구(9.9 cm)에서 가장 길었다. 산꼬리풀의 유묘 재배 시 차광처리는 경직경과 근장을 감소시키는 결과를 보였으며, 초장과 엽수는 처리에 따른 유의적인 차이는 없었다.

  • This study was aimed to establish the most effective approach for the cultivation of Veronica rotunda var. subintegra (Nakai) T.Yamaz. plants, which was expected as new ornamental plants. We conducted an experiment using plug seedlings, varied the seeding container type and seeding rate. We also varied seedling quality, planting container, soil type, and shading ratio. Seedling quality was used seedlings produced from different seeding containers and seeding rates. The seedling quality were seeding growth using 162, 200, and 288 trays, and seedings rate was used seedlings produced by sowing 1, 2, 4 and 6 seeds. As a result, 162 trays of seedlings were suitable for use in this study. Plants grown with one seed per cell in individual cells exhibited increased individual growth, but those grown with four seeds per cell exhibited better growth for the whole plant. According to seedling quality, seedlings produced in the 162 trays or with four seeds per cell showed higher growth than other seedlings. In the cultivation of V. rotunda var. subintegra (Nakai) T.Yamaz., seedling growth increased depending on container capacity for both shoot and root parts. Container material had no significant impact on seedling growth. Seedlings grew the best on horticultural substrate, and showed better growth on mixed soils with high decomposed granite content than on peatmoss.

  • The leaf growth and physiological characteristics of Forsythia saxatilis were investigated at six natural habitats under different light intensities in Bukhansan in order to figure out an appropriate growth environment for conservation and restoration of F. saxatilis that is Korean endemic plant designated as rare and endangered species. Relative light intensities (RLI) at six habitats showed from 10% to 78% of the full sun. Leaf length, leaf width, leaf area and dry leaf weight of population under highest relative light intensity (78%) were the highest. The ratio of dry leaf weight to leaf area increased with the increase of RLI. The content of photosynthetic pigments such as chlorophyll a, b and carotenoid were the highest at 78% of RLI, whereas the ratio of total chlorophyll to carotenoid content reduced according to the increase of RLI. Photosynthetic parameters, such as photosynthetic rate, also increased with the increase of RLI. The total nonstructural carbohydrate (TNC) was 1.5 times higher at 78% of RLI than that at 10% of RLI and the total soluble sugar (TSS) was the highest at 78% of RLI. In conclusion, leaf characteristics and physiological characteristics have high positive correlation with light intensity. Therefore, light condition should be primarily considered to improve growth and physiology characteristics of F. saxatilis under low light intensity.

  • This study, based on an ethnographic field-research in Hwangryong marketplace at Jangsung, explores the transformational process of local community and local marketplace from the end of the 19th century. I attempt to use methodology of oral statement and memory. In socio-economic, political and cultural sence, Hwangryong market which made the 18th century was central place of Jangsung. It was famous of cattle marketplace from the end of Lee Dynasty. The heyday of Hwangryong market is vitalized in the ruling of Japan. Japanese government collect tax and agricultural products through this marketplace. After independence of 1945, the economic function of it was weakened, but the other side political function was strengthened. The socio-economic and cultural status of this market was revitalized after the end of Korean war notwithstanding trial of moving of marketplace. But peasant migration and mechanization of agriculture from the end of 1950' had been brought about a critical moment to Hwangryong marketplace as cattle market. The opening of Honam express road at 1973 was decisively weakened socio-economic, cultural function and role of this marketplace. Consequently, Hwangryong marketplace was transformed small local market. The identity of cattle marketplace was rarely remained in recent. This inclination will not be stopped if not linking to local festival or invention of local specialities.

  • The spawning behavior and early life history of the Korean aucha perch, Coreoperca herzi were studied. The eggs were spawned in a one-layer mass, hanging from the underside of a largy stone and guarded by one male. According to the considerable size difference os eggs in the individual ovaries, it was concluded that they spawns several times within a spawning season of May~June. The ripe eggs were demersal and adhesive, and their diameter were 2.60~3.04mm with several oil globule of 0.10~0.64mm. Hatching in the tank with $19.0{\pm}1.0^{\circ}C.$ in men water temperature started from the 380 hours after fertilization. Newly-hatched larvae were measured 6.45~7.34mm in total length (TL, mean : 6.85mm), and mouth and anus were open. Melanophores were present on the head, around the yolk, and on the dorsal part of the abdominal region. 3 days old larvae were measured 7.00~7.40mm in TL (mean : 7.25mm), and they fed Daphnia sp. and Brachionus plicatilis actively. 6 days old larvae transformed to postlarval stage and they were 7.94~10.10mm in TL (mean : 9.00mm). As yolk sac were nearly absorbed, the caudal notochord flex at 45. Aggregate numbers of all fin rays were completed at over 16.90~19.80mm in TL (30 days after hatching), at which time the larvae reached the juvenile stage. In fifty days old larvae(24.60~27.10mm in TL) were similar in body form, lateral line and color to adult.
