Abstract
For callus culture of leaves and internodal tissue of Quercus acutissirna Carr. and Quercus variabitisBL, MS and GD media were supplemented with combinations of different levels of growth substances such as NAA and BAP, NAA and kinetin, 2,4-D and BAP, and 2,4-D and kinetin. The results were obtained as follows; 1. The rates of formation and growth of callus were good on the GD medium supplemented with NAA and BAP, but the values were quite variable on the MS medium. Root formation occurred at the ratio of 1 : 10-100 in the concentrations of BAP and NAA. 2. The GD medium supplemented with the combination of NAA and kinetin showed 100% callus formation. The callus grew well on the other medium except for that with low concentration of NAA and kinetin. Most of roots were developed from leaf tissue cultured on GD media. 3. The GD medium supplemented with the combination of 2,4-D and BAP also showed 100% callus formation, and growth of callus was good on both of MS and GD media. In particular, the callus derived from internodal tissue showed. the most vigorous growth and reached above 22mm diameter, when they were cultured on MS media supplemented wi th the combinations of
상수리나무와 굴참나무의 잎과 절간조직(節間組織)을 MS 및 GD배지(培地)에 식물생장조절물질(植物生長調節物質)로 NAA와 BAP, NAA와 kinetin, 2,4-D와 BAP, 2,4-D와 kinetin을 몇가지 농도(濃度)로 첨가하여 callus 배양(培養)한 결과(結果) 다음과 같은 결과(結果)를 얻을 수 있었다. 1. NAA와 BAP를 GD배지(培地)에 첨가하여 배양(培養)한 것이 callus 형성율(形成率)이 양호(良好)할 뿐만 아니라 callus 생장(生長)도 좋았으며, MS배지(培地)에서는 처리농도(處理濃度)에 따라 많은 차이(差異)가 나타났다. 뿌리는 NAA와 BAP의 농도 비(比)가 10~100배(倍)일 때 형성(形成)되었다. 2. NAA와 kinetin 조합(組合)에서도 GD배지(培地)에서 callus 형성율(形成率)이 100%로 좋았으며, callus 생장(生長)도 저농도(低濃度)의 NAA와 kinetin을 처리(處理)한 것을 제외(除外)하고는 대체적으로 양호(良好)하였다. 뿌리는 주(主)로 잎조직을 GD배지(培地)에 배양(培養)하였을 때 발생(發生)되었다. 3. 2,4-D와 BAP조합(組合)에서도 GD배지(培地)에서 callus가 100% 형성(形成)되었으며, callus의 생장(生長)은 MS 및 GD배지(培地)에서 모두 양호하였고, 특히 절간조직(節間組織)을 MS배지(培地)에 2,4-D
