Effect of silicon application on antioxidant system, biomass and yield of soybean under ozone pollution

Ozone is believed to be an important environmental pollutant causing severe losses of crops production under global change scenarios. Technical countermeasures to easing ozone stress would help ensure food security, among which adding silicon might be one of the practical approaches. Open-top chambers (OTCs) were applied in determining the effects of ozone (normal air,
