Yield loss in rice by acute ozone pollution could be recovered

Rising concentration of surface O3 threatens crop production and food security. To improve the evaluation develop efficient adaptations, it is essential to study effects acute pollution. We adopted this by open-top chamber (OTC) method found that fumigation elevated (NF40) for short (tillering jointing, heading ripening) long periods during rice growth reduced grain yield 17, 19 25%, respectively, showing both chronic pollution reduce production. Moreover, in comparison with plants under pollution, was increased when removed at different stages: 32% increment tillering jointing 34% ripening. These results suggest a possibility recover loss
