Abstract

The phenomenon known as global climate change is in all likelihood one of the main problems that will soon be facing the world. The CO2 level in the atmosphere has been steadily increasing since the beginning of the industrial era and will probably exceed 550 ppm or might even be as high as 1000 ppm by the year 2100 according to various future scenarios (IPCC 2001). The effects of changes in the gas composition of the atmosphere and in climatic factors can already be detected as a 0.7 °C rise in the global surface temperature of the Earth, a 15 cm increase in the relative sea level and the much increased frequency of extreme weather events. The frequent temperature and precipitation anomalies, combined with environmental pollution, make the present and future environment more and more stressful for plants. Although high atmospheric CO2 level has been proved to have many positive effects on plants, its role in stress resistance should also be considered. The present paper discusses the effect of elevated CO2 level on wheat and the role of environmental factors on the basis of recent findings. The connection between nitrogen supply and the down-regulation of photosynthesis, changes in cell and plant morphology, development and environmental stress response at high CO2 level are discussed in detail.
