Physiological and Yield Responses of Spring Wheat Cultivars under Realistic and Acute Levels of Ozone
Tropospheric ozone (O<sub>3</sub>) is widely recognized as the cause of substantial yield and quality reduction in crops. Most of the previous studies focused on the exposure of wheat cultivars to elevated O<sub>3</sub> levels. Our main objectives were to: (i) investigate the...
