콩에서의 조직배양 가능성을 알아보고자 콩 유묘를 기내에서 배양시킨 뒤, 여러 부위를 채취하여 각기 다른 배지 치상한 결과는 다음과 같다. 1. 줄기정단조직 배양에서는 대부분 shoot가 분화되어 완전한 식물체를 얻을 수 있었다. 2. 자엽절 조직배양에서는 multiple shoots가 나타나 대량증식에 유용했으나 배지에 따른 영향이 컸다. 3. 배축 및 상배축 조직배양에서는 callus만 분화되엇다. 4. 엽조직배양에서는 callus 분화 후 계대배양했을 때 shoot가 분화되었으나 완전한 식물체를 얻기는 힘들었다.

To study the capacity of callus and shoot formation on seedling stage in soybean, excised hypocotyl, epicotyl, shoot tip, cotyledonary node and primary leaf were cultured on artificial media (MS and B5 medium) supplemented with several hormones. Regeneration of shoots was fairly successful from shoot tip and cotyledonary node tissues in soybean. These shoots could be rooted in vitro through tissue culture technique and transplanted normally into soil. Hypocotyl and epicotyl tissues formed only callus, of which growth and appearance were different according to the kinds of media and additives. A small number of shoots were formed from primary leaf tissues, but they did not develop further.r.
