Abstract
Abstract Rising concentration of surface O 3 threatens crop production and food security. To improve the evaluation and develop efficient adaptations, it is essential to study the effects of acute O 3 pollution. We adopted this study by open‐top chamber (OTC) method and found that the fumigation of elevated O 3 (NF40) for short (tillering and jointing, heading and ripening) and long periods during rice growth reduced the grain yield by 17, 19 and 25%, respectively, showing that both of the acute and chronic O 3 pollution reduce rice production. Moreover, in comparison with the plants under chronic O 3 pollution, grain yield was increased when O 3 was removed at different stages: 32% increment at tillering and jointing and 34% increment at heading and ripening. These results suggest a possibility to recover the yield loss in rice under O 3 pollution.
