Abstract
Effect of enhancing UV-B radiation combined with nitrogen addition on the physiological response of rice cultivars(Shennong 265) was studied in potted method.The results showed that enhancing UV-B radiation decreases content of chlorophyll a,chlorophyll b,SOD and POD activities,but increases the content of carotenoid,MDA and electrolyte leskage.As the increaseing dose of nitrogen,the content of chlorophyll a,chlorophyll b is increased and MDA is decreased,electrolyte leskage and soluble protein is not effected,and the content of SOD is increased firstly,then decreased under enhancing.UV-B radiation.
