Does long-term cultivation of saplings under elevated CO2 concentration influence their photosynthetic response to temperature?
BACKGROUND AND AIMS Plants growing under elevated atmospheric CO2 concentrations often have reduced stomatal conductance and subsequently increased leaf temperature. This study therefore tested the hypothesis that under long-term elevated CO2 the temperature optima of photosynthetic processes will shift towards higher temperatures and the thermostability of the photosynthetic apparatus will inc...
متن کاملElevated atmospheric CO2 concentration changes ectomycorrhizal
ferent species of fungi having very different physiologies and morphologies that, in turn, confer a range of different benefits to the host plant. To test the hypothesis that elevated CO2 leads to changes in the assemblage of ectomycorrhizae associated with trees, we examined the number and frequency of ectomycorrhizal morphotypes colonizing roots of Betula papyrifera Marsh. saplings grown at a...
متن کاملPhotosynthetic responses of Scots pine to elevated CO2 and nit
trees, age 25--30 years, were subjected to two soil-nitrogensupply regimes and to elevated atmospheric CO2 concentrations by the branch-in-bag method from April 15 to September 15 for two or three years. Gas exchange in detached shoots was measured in a diffuse radiation field. Seven parameters associated with photosynthetic performance and two describing stomatal conductance were determined to...
متن کاملAcclimation of photosynthetic microorganisms to changing ambient CO2 concentration.
P microorganisms can acclimate to a wide range of CO2 concentration, from as low as 0.001% to '10% CO2 (volyvol in the air in equilibrium with their environment). Some can even grow in the presence of 40% CO2 (1). Acclimation to a limiting CO2 level, well below the Km(CO2) of their carboxylating enzyme, Rubisco (ribulose 1,5-bisphosphate carboxylaseyoxygenase), is achieved by substantial physio...
متن کاملCorrection: Interactive Effects of Elevated CO2 Concentration and Irrigation on Photosynthetic Parameters and Yield of Maize in Northeast China
Maize is one of the major cultivated crops of China, having a central role in ensuring the food security of the country. There has been a significant increase in studies of maize under interactive effects of elevated CO2 concentration ([CO2]) and other factors, yet the interactive effects of elevated [CO2] and increasing precipitation on maize has remained unclear. In this study, a manipulative...
