Response of agronomic and forest species to elevated atmospheric carbon dioxide
TLDR
The effects of atmospheric carbon dioxide on corn, soybeans, loblolly pine, and sweetgum were studied in the field during a growing season and net photosynthesis increased with increasing carbon dioxide concentration in soybeans andsweetgum, but was unaffected in corn.Abstract:
The effects of atmospheric carbon dioxide on corn, soybeans, loblolly pine, and sweetgum were studied in the field during a growing season. The plants were exposed to a range of concentrations of carbon dioxide day and night in open-topped, flow-through chambers. At a mean daytime carbon dioxide concentration of 910 parts per million, increases in total biomass ranged from 157 to 186 percent of the control values. Seed yield and wood volume increased and there were changes in plant anatomy and form. Net photosynthesis increased with increasing carbon dioxide concentration in soybeans and sweetgum, but was unaffected in corn. Water use efficiency also increased in corn, soybeans, and sweetgum.read more

The Response of Natural Ecosystems to the Rising Global CO2 Levels
TL;DR: Because CO2 is a greenhouse gas, its increase in the atmosphere may influence the earth's energy budget and influence world ecosystems by direct effects on plant growth and development.

The Direct Effects of Increase in the Global Atmospheric CO2 Concentration on Natural and Commercial Temperate Trees and Forests
Derek Eamus,P.G. Jarvis +1 more
TL;DR: This chapter discusses the direct effects of increase in the global atmospheric CO 2 concentration on natural and commercial temperate trees and forests and the impact on the ecology and environment of woods and forests, and the downstream, socio-economic consequences.

Plant responses to atmospheric CO2 enrichment with emphasis on roots and the rhizosphere.
TL;DR: Experiments on root and rhizosphere response in plants grown in CO(2)-enriched atmospheres will be reviewed and, where possible, collectively integrated, to offer a series of hypotheses which are considered as priority targets for future research.

Tropical Forests and the Global Carbon Cycle
TL;DR: New data on the three major determinants of the carbon release from tropical forest clearing are used in a computer model that simulates land use change and its effects on the carbon content of vegetation and soil in order to calculate the net flux of carbon dioxide between tropical ecosystems and the atmosphere.

Elevated CO2 and plant structure: a review
TL;DR: A review of the literature suggests that cell division, cell expansion, and cell patterning may be affected, driven mainly by increased substrate (sucrose) availability and perhaps also by differential expression of genes involved in cell cycling or cell expansion.

Elevated atmospheric partial pressure of CO2 and plant growth
TL;DR: The data show that plant responses to elevated atmospheric partial pressure of CO2 depend on complex of partially compensatory processes which are not readily predictable.

An Open-Top Field Chamber to Assess the Impact of Air Pollution on Plants
TL;DR: In this article, the authors describe the design and evaluation of an open-top field chamber that was developed to provide an environment more closely resembling ambient conditions than the environment found in closed-top chambers.

Carbon Dioxide Concentration, Photosynthesis, and Dry Matter Production
TL;DR: In this article, the effects on photosynthesis and dry matter production by increased levels of CO/sub 2/ are examined, based on the assumption that the rate of photosynthesis is limited chiefly by CO 2 concentration.

Dispensing and monitoring ozone in open-top field chambers for plant-effects studies.
TL;DR: New methods for dispensing and monitoring ozone in open top field chambers; such chambers are used in studies of the effects of oxidants on plants and are fewer than those induced in closed chamber designs.
