Effects of Enhanced UV-B Radiation and Tropospheric Ozone on Physiological and Biochemical Characteristics of Field Grown Wheat
Ambasht, N.K. | Agrawal, M.
Experiments were conducted under field conditions to assess the growth, physiological and biochemical responses of wheat plants (Triticum aestivum L.) to supplemental UV-B radiation (7.1 kJ m⁻²) and enhanced ozone (0.07 μmol mol⁻¹) separately and in combination. Enhanced UV-B radiation and O₃ reduced biomass, yield, photosynthetic rate, chlorophyll, carotenoid and ascorbic acid contents and catalase activity, whereas increased total phenol content and peroxidase activity. Contents of flavonoids increased due to UV-B treatment. The interactive effects were, however, less than additive.
