Effects of Succinic Acid 2, 2-Dimethylhydrazide on the Metabolism in the Germinating Pea Seedlings = SADH처리가 발아하는 완두자엽의 대사작용에 미치는 영향

국문 초록 (Abstract)

1. SADH 처리는 완두와 포도 절간세포의 길이와 수를 감소 시켰으며 그 반응은 포도보다 완두에서 더 예민하게 작용하였다.
2. SADH 농도의 증가에 따라서 완두 실생의 싹과 뿌리 생장은 억제 되었으며 높은 농도에서는 자엽의 중 ? 이 더 무거웠다.
3. SADH 처리에 의하여 발아하는 완두 자엽내의 가용성 총당, 환원당, 가용성 단백질, 유리아미노산, RNA 및 DNA의 함량은 변하지 않았다.
4. SADH 처리에 의하여 발아하는 완두 자엽내의 Amylase, Phosphatase 및 Protease 활성은 유의하게 영향을 미치지 않았다.
5. SADH 처리는 발아하는 완두자엽의 호흡 환성을 처리후 2일째에 억제 하였다.
6. SADH 처리에 의한 완두의 생장억제 작용은 지베레린에 의하여 약간 감소 되었다.

다국어 초록 (Multilingual Abstract)

1. The length and number of cells in pea and grape internode were reduced by SADH applications and its response was more sensitive to the pea seedlings than to the grape.
2. In the germinating pea seedling, the growth of sprout and root was gradually suppressed with increasing concentrations of SADH. High concentration of SADH treatment resulted in an increased weight of cotyledons.
3. Total soluble and reducing sugars, soluble protein, free amino acid, RNA and DNA contents were not altered by SADH treatments in the germination pea cotyledons.
4. The activities of amylase, phosphatase and protease were not significantly afffected by SADH treatments in the germinating pea cotyledons.
5. Respiratory activity was reduced at 2 day by SADH applications in the germinating pea cotyledons.
6. Inhibiting action of the growth by SADH was slightly was slightly reduced by gibberellic acid in the germinating pea seedlings.
