Abstract
담배의 생장과 광합성 색소 및 효소에 대한 카드뮴의 독성과 이에 대한 칼슘의 영향을 연구하였다. 카드뮴에 의한 생장과 엽록소 수준에서의 억제 현상은 칼슘에 의해 회복되었다. 특히, 엽록소의 함량은 카드뮴만 처리한 것 보다 카드뮴과 칼슘을 같이 처리하였을 때 현저하게 증가하였다. 또한 rubisco의 활성과 함량은 카드뮴을 처리한 것 보다 처리하지 않았을 때 현저하게 감소하였으며, 카드뮴의 이러한 효과는 칼슘에 의해 환원되었다. Rubisco activase의 활성과 함량도 rubisco와 같은 경향을 보였다. Rubisco에서 카드뮴과 칼슘에 의해 유도되는 이와 같은 변화는 rubisco activase에 의해 기인됨을 의미한다. This investigation was performed to study Cd toxicity and the influence of Ca on Cd toxicity in growth, and photosynthetic pigments and enzymes in tobacco. Cd inhibited both growth and level of chlorophyll, but the inhibition was compensated by the treatment of Ca. Especially, chlorophyll content was significantly increased by the combination of Cd and Ca treatment compared with Cd treatment alone. In addition, activity and content of rubisco by Cd treatment was also significantly lesser than the non-treated control. The highly reduced activity of rubisco was minimized by the combined treatment of Ca to Cd. Rubisco activase activity and content also showed a pattern of change similar to the rubisco level, suggesting that Cd- and Ca-induced changes of rubisco could be caused by rubisco activase.
