| description | Ground-level ozone affects agricultural crops and trees, including rice plants through reduction in antioxidant activities, physiological performance and yield production. For that reason, it is essential to identify the most tolerance rice cultivar as the ozone concentration in Malaysia is on the rise. In this study, four Malaysian local rice cultivars representing old cultivars, current dominant planted cultivar and newly introduced cultivar were exposed to two regimes of elevated ozone i.e. 60 and 120 ppb to determine their biochemical and yield response. For the biochemical aspect, superoxide dismutase (SOD) and glutathione reductase (GR) expression were examined because of their role as the first line of defence system and tolerance indicator towards elevated ozone exposure while yield performance was determined by total grain weight. Each of the cultivars exhibits statistically significant (p<0.05) susceptibility towards elevated ozone exposure in the range of 5-15% yield reduction with the old cultivar (Mahsuri) as the most tolerant towards ozone stress. |
