Chilling stress, one of the most important limiting environmental factors, delays plants growth and development and reduces crops yield. Chilling stress causes cell membrane damage, which triggers an excessive production of reactive oxygen species (ROS) such as superoxide (O2-), hydroxyl radicals (•OH) and hydrogen peroxide (H2O2). ROS are cytotoxic compounds...

To determine the effects of temperature change on photosynthesis and growth development of wheat, seedlings were subjected to UV-B radiation under different temperature. Photosynthesis parameters (photosynthesis and net photosynthesis, stomatal conductance, carboxylation efficiency, etc.) and biomass were determined. The results indicated that photosynthesis parameters and biomass increased with temperature until...
