Abstract

This study was carried out to investigate the effects or abscisic acid (ABA), three concentrations, on growth, activities of antioxidant-related enzymes and grain yield of two rice plants (Oryza sativa L. cv. Hwamyungbyeo and cv. Namchunbyeo) exposed to ozone (0.150 ppm) for 6 hours a day for 30 days. The leaf chlorop0hyll contents, plant height, and tillering numbers were not shown significant difference. But ABA 10$^{-5}$ M treatment affects to growth slightly. In all concentrations of ABA, superoxide dismutase (SOB) activities were increased at tillering stage of Namchunbyeo which was exposed to ozone. It is considered that the optimum concentration of ABA is 10$^{-5}$ M for minimizing loss of grain yield loss.

벼의 오존 처리에 따른 피해 경감 효과를 조사하기 위해 자포니카품종인 화명벼와 통일형 품종인 남천벼에 오존처리와 함께 식물생장조절제인 ABA를 농도별로 30일 동안 엽면 처리한 후 분얼기 및 수잉기에 생육, 수량 및 항산화 효소 활성의 변화를 조사한 결과를 요약하면 다음과 같다. 1. 오존처리에 의해 화명벼 수잉기의 ABA무처리에서 가장 낮은 초장억제를 보였고 ABA $10^{-4}$ M 처리에서 초장이 커지는 것을 볼 수 있다. 분얼기의 오존처리에 의한 분얼수의 감소는 크지 않았으나 분얼수 확보를 위해서는 $10^{-4}$ M 처리가 바람직한 것으로 나타났다. 화명벼 분얼기 오존처리의 경우는 ABA $10^{-4}$ M, 화명벼 수잉기 오존처리의 경우는 $10^{-3}$M, 남천벼 분얼기 오존처리의 경우는 ABA $10^{-4}$ M,그리고 남천벼 수잉기 오존처리의 경우는 ABA $10^{-4}$ M처리가 엽록소 함량 감소를 적게 하는 것으로 나타났다. 2. ABA $10^{-5}$M처리를 할 때 오존 피해에 의한 수량 감소를 최소화하는데 유리한 것으로 판단된다. 3. 남천벼 분얼기 오존처리의 경우 모든 ABA 처리에서 SOD 활성이 증가한 것으로 나타났으며, APX는 분얼기와 수잉기 화명벼의 오존 15일간 처리에서 활성이 약간 낮아지는 것으로 나타났고, 분얼기 벼의 GPX활성이 다른 처리구들에 비해 낮게 나타났다.
