Leaf tissue segments of cabbage (Brassica oleracea. L.) were cultured on the MS medium supplemented with BA and 2, 4-D or NAA. 2, 4-D promoted callus induction but not shoot or root organogenesis. The highest callus induction frequency obtained at treatment of BA 0.2 and 2, 4-D 0.2 ㎎/l. High concentration of 2, 4-D 5.0㎎/l inhibited callus formation. BA promoted shoot formation at the 1.0㎎/ℓ and complementary treatment of BA and NAA was more effective on the formation of shoot and root. Multiple shoots were formed on the medium supplemented with BA 1.0 and NAA 0.5-1.0㎎/l, and BA 0.5 and NAA 2.0㎎/l. Higher concentration of NAA 5.0㎎/ℓ inhibited shoot formation. The highest root formation was induced at the NAA 1.0-2.0㎎/l. Embryogenesis was not induced on leaf disk culture.

The purpose of this paper is to promote Chaebol reform which is necessary for the future of Korean economy by presenting the contributions of Korean Chaebol to economic development of Korea and limitation of Korean Chaebol system disclosed in Asian Financial Crisis. Korea has no other business organization which can replace the role of Chaebol at the present time. Therefore, we need to find measures to make Chaebol function in affirmative side by Chaebol Reform rather than disorganizing Chaebol, especially in the economic environment of Korea where market system does not work properly. Chaebol Reform includes transparency in management, separation of management and ownership, improvements of financial structures, concentration on core competence, solidification of responsibility in management, etc. Key words : Chaebol, Reform, Effectiveness of Chaebol system

인삼(人蔘)의 육종(育種)을 위(爲)한 몇가지 기초정보(基礎情報)를 얻기 위(爲)하여 국내(國內) 육성계통(育成系統) 16계통(系統)을 대상(對象)으로 하여 조사(調査) 분석(分析)하였던 바 그 결과(結果)를 요약(要約)하면 다음과 같다. 1. 인삼(人蔘)의 각 주요(主要) 양적(量的) 형질중(形質中) 경장(莖長)이(0.7050) 가장 높은 유전력(遺傳力)을 보였고 반면 엽장(葉長)의 유전력(遺傳力)이 (0.5674) 가장 낮았다. 2. 엽장(葉長)과 경직경간(莖直徑間)의 유전형(遺傳型) 상관(相關)이 (0.9844) 가장 높았고, 엽장(葉長)과 경장간(莖長間)의 유전형(遺傳型) 상관(相關)이 (0.8649) 가장 낮았으나 표현형(表現型) 상관(相關)에 있어서는 경장(莖長)과 경직경간(莖直徑間)이 (0.8788) 가장 높았으며 경장(莖長)과 경직경간(莖直徑間)이 (0.7950) 가장 낮았다. 3. 각 형질간(形質間)의 공유전력은 경장(莖長)과 경직경간(莖直徑間)이 가장 높았으며 엽장(葉長)과 경장간(莖長間)이 가장 낮은 값을 나타내었다. 4. 재식위치(栽植位置)에 따르는 각 형질(形質)의 변이(變異) 정도(程度)는 경장(莖長)이 가장 컸던 반면 경직경(莖直徑)에서 가장 적은 경향(傾向)이 있다. To obtain several foundamental information for the breeding of Korean Ginseng. 16 line selecteds in Korea were investigated and analyzed. The results obtained are as follows : 1. In all quantitative genetic characters of Korean Ginseng, the stem length showed the highest heritability(0.7050) and the leaf length the lowest(0.5674). 2. The genotypic correlation was showen the highest value (0.8649) at between the leaf length and the stem diameter and the lowest value(0.8649) at between the leaf length and the stem length, but the phnotypic correlation was shown the highest value (0.8788) at between the stem length and the stem dimeter and the lowest value (0.7950) at between the leaf length and stem length. 3. The co-heritability between the stem length and the stem diameter showed the highest value(0.6124) and that between the leaf length and the stem length showed the lowest value(0.5471). 4. The inter-class correlation among the planting location showed the highest value at the stem length and the lowest value at the stem diameter.
