This study was carried out to investigate the kinds of fresh wild vegetables, the number of street stalsl, seller's age, and the selling list of items of the street stall in the five-day traditional markets of Gyeongnam Tongyoung and Namhae, Jeonnam Naju and Younggwang, Jeonbuk Iksan and Jangsu, from March to May, 2005. The number of street stalls selling fresh wild vegetables was forty nine in Tongyoung, twenty five in Namhae, thirty in Naju, eighteen in Younggwang, one hundred and thirty in Iksan, and seventeen in Jangsu. The selling lists of items totaled forty items; thirty in Tongyoung, seventeen in Namhae, twenty in Naju, sixteen in Younggwang, twenty seven in Iksan, and thirteen in Jangsu. The main kinds were Aster scaber, Aralia elata, Pteridium aquilinum var. latusculum, Artemisia princeps, Sedum sarmentosum, Oenanthe javanica, Pla쇼codon grandiflorum, Petasites japonicus and Allium monanthum. sprouts or woody plants such as Arazia elate, Ailanthus altissima, Meliosma oldhamii, and Kalopanax pictus were also being sold. About $80{\%}$ of the sellers were over fifty one years old. Half of the sellers were at least sixty years old. More thab $77\%$ of the street stalls in the traditional markets sell fewer than four kinds of fresh wild vegetables.

Antioxidant activity, total phenolics level and cytotoxicity of the methanol extracts from the young sprouts of 5 Korean woody salad plants were determined. Methanol extracts of Kalopanax pictus had the highest DPPH radical scavenging activity, with an $IC_{50}$ value of 23.5mg $100g^{-1}$, and followed by Valeriana fauriei(43.1mg $100g^{-1}$), and Morus alba(>100mg $100g^{-1}$). Total phenolic content showed the highest amount in methanol extracts from Kalopanax pictus(23.7mg $100g^{-1}$), and followed by Valeriana fauriei(22.7mg $100g^{-1}$), Aralia elata(16.8mg $100g^{-1}$) and Morus alba(14.2mg $100g^{-1}$). In a MTT assay, methanol extracts of Aralia elata with $IC_{50}$ values of 151.0 and $140.7{\mu}g\;mL^{-1}$ showed the most potent cytotoxicity on Calu-6 and MCF-7, respectively. On the other hand, methanol extracts of Kalopanax pictus($IC_{50}=96.5{\mu}g\;mL^{-1}$) showed the highest activity against HCT-116, and followed by those of Aralia elata($123.3{\mu}g\;mL^{-1}$), and Actinidia arguta($162.0{\mu}g\;mL^{-1}$). Total phenolic content of the tested plant extracts was correlated with the DPPH radical scavenging activity, suggesting the phenolic compounds may contribute to the antioxidant properties of Korean salad plants.

Aralia elata is found in mountain areas all over Korean peninsula. Aralia elata is the scientific name for Japanese angelica tree. The tree belongs to the family Araliaceae, commonly known as ginseng family. Bud sprouts from apical shoot tip of the plants are rich in flavor and thus mainly used for both folk medicine and vegetable. The stalks with apical buds are gathered in the early spring and planted in sandy soil or water in the greenhouse. The sprouting buds are then collected and sold as fresh vegetable. Although the plants have been used for food, they have been cultivated in a very small scale. In spring, local farmers just go around mountain areas to search the trees and gather the stalks as much as they get and sell them to the market. No conservation efforts have been made to stop the exploitation or to save the dwindling population. We tried to provide local farmers with the plants that may be used as an alternative to stalks from wild populations. This will bel! p conserve the wild populations. However, it is hard to propagate them either by conventional cuttings or by seed germination in a short period of time. Mass propagation using tissue culture systems have shown a great promise with several woody plants. Recently we developed a mass propagation technique via somatic embryogenesis system using mature and/or juvenile explants for Aralia elata. Several factors affecting somatic embryogenesis system including SE(somatic embryo) induction, embryogenic callus proliferation, SE germination, plant regeneration and transplanting to field frill be presented. And some problems arising for the somatic embryogenesis system will be also discussed.

This study was conducted to develop the regulating methods for the optimal harvest stage of new sprout for woody plants, and to clarify the effects of storage condition and period on the growth of new sprout formed of Aralia elata cv. 'Jeongkwang'. Japanese angelica tree were collected in the Jangheung district of Jeonnam on 20. March, 2005, and those cut branches were stored at $5{\pm}2^{\circ}C$ and 80 to 90% of the relative humidity, and were cut in water. Survival rate of cut branches for Aralia elata cv. 'Jeongkwang' was significantly increased when that was used for the cutting after the collection with no storage. And those survival rate was much more increased when that was stored at 80 to 90% of relative humidity than 40 to 50% of relative humidity. Number of new sprouts formed which were not stored immediately after the collection 3.2 to 3.4, and that were stored at cold storage room before cutting and cut on 1. June and 1. August were 5.1 to 5.3. Leaf growth of cut branches cut in water on 20. March started at ten days after cutting, and that on 1. June and 1. August at one to two days after cutting. Slow and mature sprout growth of Aralia elata cv. 'Jeongkwang' which were cut in water were different by the cold storage periods. Nineteen days were needed for the mature growth of sprout when cut in water on 20. March, and thirteen days on 1. August.

목본류의 절지를 이용한 싹기름 채소생산의 기술을 개발하기 위하여 뽕나무 가지를 2006년 4월 13일에 절지하여 $4{\sim}6^{\circ}C$의 저온저장고에서 습도조건($40{\sim}50%$ 및 $80{\sim}90%$)에 따른 생존율과 $1{\sim}3$개씩의 싹을 붙인 가지를 자른 후 싹기름을 했을 때 저온저장 일수에 따른 새싹의 생장 정도를 조사하였다. 뽕나무 절지의 생존율은 저장일수가 길수록 낮아져 저온저장을 하지 않은 채취 당일에 싹기름을 한 것은 97.4%였고, 122일 저온저장한 후 싹기름을 한 절지는 $40{\sim}50%$의 습도조건에서 34.2%, $80{\sim}90%$의 습도조건에서 저장한 것은 85.7%였다. 또한 절지의 저장일수가 길수록 새싹의 잎수가 증가하는 경향을 보였고, 싹의 길이와 폭도 큰 경향을 나타내었다. 따라서 뽕나무의 절지를 $4{\sim}6^{\circ}C$의 저장온도와 $80{\sim}90%$의 습도조건에서 저장한 후 $1{\sim}3$개씩의 싹을 붙인 가지를 잘라 싹기름을 하면 새싹 채소의 생산이 가능한 것으로 나타났다.
