Climate Change and Photosynthetic Efficiency of Wheat and Maize

Recently, one of the most important environmental challenges that face plant production is the phenomenon of climate change that results mainly from the increases in temperature and elevation of CO2 concentrations in air. This investigation was conducted to detect the effect of temperature increase alone and in combination with CO2 concentration increase on growth, productivity and biochemical constituents of wheat (C3 crop) and maize (C4 crop).
