Effects of elevated tropospheric ozone on biochemical activities and yield of selected indica rice plants

Abstract

Ozone had been recognized as one of the major threats towards crops, including rice by giving the adverse effects on biochemical activities, physiological performance and yield production. In Malaysia, anthropogenic sources are rapidly increasing and this condition had caused increased ozone formation. Domestic rice consumption is projected to be high due to population increase. High production of rice is targeted from the existing rice planting areas. Since there is no plan by the government to increase the area for rice cultivation, there is an urgent need to identify the most tolerant cultivar to ozone.
