초록

본 연구는 기내 배양한 나도 풍란에 식물생장억제제인 Uniconazole, Ancymidol, Paclobutrazol의 종류별, 농도별 처리가 식물체내 내생 GA 유사물질의 활성 및 ABA 유사물질의 함량의 변화에 미치는 영향을 알아보기 위하여 실시되었다. 지상부인 잎에서는 Uniconazole 0.05 mg/L, Ancymidol 0.1 mg/L, Paclobutrazol 0.3 mg/L 처리 시 ABA 유사물질의 함량은 대조구보다 낮았으며, GA유사물질의 활성은 대조구 보다 높거나 비슷한 수준이었다. 하지만 처리농도가 높아짐에 따라 ABA 유사물질의 농도는 높아졌으나, GA 유사물질의 활성은 비교적 억제되었다. 지하부인 뿌리에서는 Uniconazole 0.05, 0.2mg/L, Ancymidol 0.2 mg/L, Paclobutrazol 0.1 mg/L 처리에서 ABA 유사물질의 함량이 대조구보다 낮았고, 그 이상의 농도에서는 높았다. GA 유사물질의 활성은 비교적 저 농도에서는 높았으나, 고농도 처리에서는 저 농도와 비교하여 활성이 억제되었다.

This experiment was conducted to identify the effect of several plant growth retardants on endogenous ABA-like substance content and GA-like substance activity in seedlings of Sedirea japonica cultured in vitro. When seedlings of Sedirea japonica were treated with low concentration of 0.05 mg/L Uniconazole, 0.1 mg/L Ancymidol and 0.3 mg/L Paclobutrazol, the content of ABA-like substances of the leaf was lower than that of the control. However, the activity of GA-like substances was similar or higher in treated seedlings. In the mid and high concentrations of three kinds of growth retardants, the ABA-like substance content was increased, but GA-like substance activity was inhibited. The content of ABA-like substances in the root was lower in 0.05 and 0.2 mg/L Uniconazole, 0.2 mg/L Ancymidol and 0.1 mg/L Paclobutrazol treatments than that of the control, but in the mid and high concentration treatments, the content was increased. GA-like substance activity in low concentration was increased but in the mid and high concentration, the activity was inhibited compared with low concentration treatment.
