Abstract
본 연구에서는 담배식물의 생장과 glutathione reductase와 catalase의 활성에 미치는 p-CA, BA 및 SA의 영향을 연구하였다. 담배식물의 생장에 미치는 p-CA, BA 및 SA의 영향을 알아보기 위하여, $10^{-5}$ mM p-CA, BA 및 SA가 각각 함유된 MS배지에서 배양한 후 20일부터 50일까지 10일 간격으로 담배의 생장을 비교하였다. 3가지 물질 모두에 의해 50일에서 생장이 가장 잘 되였다. Glutathione reductase의 활성에 미치는 효과를 측정한 결과, BA의 활성은 대조구보다 감소하였으며, p-CA 역시 활성이 감소하였고, SA의 활성은 증가하였다. 또한 모두 40일에서 가장 활성이 높았다. Catalase의 활성에 미치는 효과를 측정한 결과, SA의 활성은 증가하였으며, BA와 p-CA의 활성은 감소하였다. 또한 모든 실험구에서 40일에 활성이 가장 양호하였다. 결론적으로 p-CA와 BA는 담배식물의 생장을 촉진시켰으며, 50일에서 생장이 가장 양호하였으나 항산화 효소의 활성을 억제하였다. SA는 담배식물의 생장을 억제시켰으나 항산화 효소의 활성은 촉진시켰으며, 40일에서 가장 활성이 양호하였다. Effects of p-coumaric acid (p-CA), benzoic acid (BA), and salicylic acid (SA) on the activities of glutathione reductase and catalase were studied in in vitro grown tobacco plants. After culturing the tobacco plants in MS medium containing $10^{-5}$ mM of p-CA, BA, and SA, the increase in the activities of two enzymes, glutathione reductase and catalase, were compared from day 20 to day 50 day, with an interval of 10 days. The growth of the tobacco plants treated with p-CA, BA, and SA was the highest on day 50. Analysis of the effect of the three substances on the activity of glutathione reductase showed that BA and p-CA decreased the activity of the enzyme compared with a control, and SA increased the activity of the enzyme. All of them showed the highest activity on day 40. SA increased the activity of catalase, but BA and p-CA reduced the activity of this enzyme. In all the experimental groups, the activity was the highest on day 40. In conclusion, p-CA and BA appear to promote the growth of tobacco plants. The growth was the best on day 50, but the activity of the antioxidative enzyme was inhibited. On the contrary, SA seemed to inhibit the growth of the tobacco plants but to promote the activity of glutathione reductase and catalase. The growth of the plants treated with SA was best on day 40.
