Track 2-07: Climate Change Impacts on Grassland Production, Composition, Distribution and Adaptation
Description
Due to human activities, the concentration of carbon dioxide (CO2) in the Earth’s atmosphere is rising rapidly. The atmospheric CO2 concentration has increased to 360 μmol/mol from 280 μmol/mol at the end of the 19th century, and it will be doubled in the late 21st century (Alcamo 1996). Since CO2 is a key factor for plant growth and development, much more attention has been paid to the effect of an elevated atmospheric CO2 concentration on many ecosystem processes (Hungate et al. 1997; Idso et al. 1992; Oren et al. 2001; Sun et al. 2002).
Caragana davazamcii and Caragana korshinskii which belong to legumes family play an extremely important role in protection soil from the wind, water conservation and eco-environment protection in Mu Us sand land of Northwest China. There have been a lot of research done on ecophysiological characteristics of caragana species under natural conditions, but there has been little focused on the physiological changes that may occur under stimulated CO2 enrichment. This study compares the changes of photosynthetic characteristics of two caragana species to simultaneous CO2 enrichment and explores their adaptation mechanisms.
