TREE GROWTH UNDER THE IMPACT OF ELEVATED CO2 CONCENTRATION AND SOME PRACTICAL ASSESSMENTS
2003
Urban O., Pokorny R.
The dynamics of forest ecosystems depend on interactions between a number of biogeochemical cycles (i.e. carbon, nutrient, and hydrological cycles) that could be modified by human actions. Conversely, these ecosystems are important components that create sources and sinks of important greenhouse gasses, e.g. carbon dioxide, methane etc. Especially, carbon is exchanged naturally through photosynthesis, respiration, decomposition, and combustion processes. Continuous increase of atmospheric carbon dioxide concentration([CO2]) has led to extensive research describing impacts of elevated [CO2] on basic physiological processes and consequent changes of biomass production on the whole plant level. In this paper we present several results obtained predominantly with Norway spruce trees. Moreover, we bring a few practical recommendations for the forest management under the impact of elevated [CO2]. Keywords: elevated CO2, forest management, physiology
