Narrative as Dialectic Abductionf changing CO. levels on vegetation since the last glaciation are thought to have been at least as great, if not greater, than those which should be expected for a doubling of current CO. levels. Atmospheric CO. concentrations below 200 ppm are thought to have been instrumental in the rise of the C.

Open top chambers for exposing plant canopies to elevated CO2 concentration and for measuring net gar tracking gas exchange between natural vegetation and the ambient air is described. This modification consists of the addition of a top with exit chimney to reduce dilution of chamber CO. by external ambient air, is quickly made and permits estimation of the effects of elevated CO. and water vapor

Analysing the responses of photosynthetic CO2 assimilation to long-term elevation of atmospheric CO2sponse of CO. assimilation to intercellular CO. concentration allows quantitative determination of the limitation imposed by stomata, carboxylation efficiency, and the rate of regeneration of ribulose 1:5 bisphosphate. Chlorophyll fluorescence provides a rapid method for detecting photoinhibition in

Root growth and functioning under atmospheric CO2 enrichmentment since nodule mass is increased, concomitant with an increase in root length. The papers available so far on the influence of CO. enrichment on mycorrhizal functioning suggest that carbon allocation to the roots might be increased, but also here more experiments are needed.
