Influences of elevated atmospheric CO₂ and water stress on photosynthesis and fluorescence of loblolly pine, red maple, and sweetgum
Changes in light harvesting ability and other physiological responses could int1uence the competitive outcomes of tree species in a future elevated CO₂ atmosphere. Photosynthetic light response curves were constructed with a closed photosynthesis system (LI-COR, Inc. Lincoln, NB) in order to …

Interactive Effects of Ferulic Acid and Irradiance on Plant Growth and Photosynthetic Rate
… determine how levels of irradiance modify plant response to a known allelochemical stress. Using a split plot design, the effects of irradiance and ferulic acid (FA) on growth, biomass allocation and plant photosynthetic capacity were monitored in summer greenhouse experiments. The experimental …

Environmental Influences on Gas Exchange in Fertilized and Non-Fertilized Stands of Loblolly Pine
… Common empirical gas exchange models reveal that light and vapor pressure deficit (VPD) explain a majority of the variation observed in photosynthesis and transpiration, respectively. Conductance was not modeled since environmental variation did not adequately explain conductance patterns. …

Productivity, physiology, community dynamics, and ecological impacts of a grassland agro-ecosystem: integrating field studies and ecosystem modeling
… rarely investigated. Therefore, I investigated responses of these factors to harvest time in prairie mixtures by conducting experiments in a restored tallgrass prairie in Urbana, IL. The results suggest that the optimal harvest time that maximizes expected net returns and balances feedstock …

Regulation of the stomatal response to red light
Regulation of the stomatal response to red light Stomata are microscopic pores in the leaf epidermis which govern the exchange of CO2 and water vapour between the plant and surrounding atmosphere. Highly specialised guard cells surround each stomatal pore and regulate stomatal aperture in response …
