Abstract

In past few years, atmospheric concentrations of carbon dioxide (CO₂) and tropospheric ozone (O₃) have increased due to anthropogenic activities. CO₂ enhances the plant growth and surface level of O₃ is a well-known phyto-toxic pollutant. Present study was conducted to assess the impact of elevated levels of CO₂ and O₃, singly and in combination on two wheat cultivars HUW-37 and K-9107 on their growth, yield attributes and grain quality in open top chambers (OTCs). Wheat plants under elevated CO₂ (EC) showed increment in growth parameters while exposure to elevated O₃ (EO) showed an opposite trend than EC. In elevated CO₂+O₃ (ECO) exposure, elevated CO₂ fully protected wheat cultivars against negative effects of O₃. Yield parameters showed significant increase in EC followed by ECO and in EO, significant reductions in yield were noticed in both the cultivars. Protein and total free amino-acids decreased in grains of EC, ECO and EO in both the test cultivars. Total soluble sugars and starch contents in grains increased due to EC and ECO and decreased in EO, however reducing sugars showed an opposite trend in both the cultivars. The yield data obtained from the experiment showed cultivar specific response as cultivar HUW-37 proved to be sensitive as compared to K-9107 against ambient and elevated levels of O₃. The study also concludes that elevated CO₂ nullified the negative impact of elevated O₃ in both the test cultivars of wheat.
