In the present study wheat (Triticum aestivum) cultivar HD 2967 was exposed to ambient and elevated levels of O₃ and PM deposition, with and without exogenous application of ascorbic acid (AA). Cultivar HD 2967 exposed to eight treatments in free air O₃ enrichment facility and the assessed results showed that wheat cultivar, growth, biochemical, physiological and yield attributes were variably but adversely affected by combined exposure to O₃ and PM deposition. PM deposition clogged stomata and enhanced leaf temperature. However, plants exposed to O₃ and PM deposition and treated with AA exhibited less reduction in yield as compared to plants exposed to O₃ and PM deposition without AA treatment. The decline in grain yield of HD 2967 due to combined exposure of O₃ and PM deposition were in the range of 4%–17%. AA spray partially mitigated ozone and PM deposition adverse impact and enhanced wheat yield by 16%.

在本研究中，小麦（普通小麦）栽培品种 HD 2967 暴露于环境和升高水平的 O ₃和 PM 沉积，有或没有外源性应用抗坏血酸 (AA)。品种 HD 2967 在自由空气 O ₃富集设施中暴露于八次处理，评估结果表明小麦品种、生长、生化、生理和产量属性受到 O ₃和 PM 沉积的组合暴露的不同但不利的影响。PM 沉积堵塞气孔并提高叶温。然而，植物暴露于ö ₃和PM沉积并用AA处理表现出较少的产率减少相比，暴露于0植物₃和未经 AA 处理的 PM 沉积。由于 O ₃和 PM 沉积的联合暴露，HD 2967 的谷物产量下降在4%–17% 的范围内。AA 喷雾部分减轻了臭氧和​​ PM 沉积的不利影响，并将小麦产量提高了 16%。
