Effect of elevated carbon dioxide concentration on carbon assimilation under fluctuating light

Popis výsledku v původním jazyce

Natural fluctuations in light intensity may significantly affect the amount of CO2 assimilated by plants and ecosystems. Little is known, however, about the interactive effect of dynamic light conditions and atmospheric CO2 concentrations. The hypothesisthat elevated CO2 concentration (EC; 700 umol CO2/ mol) increases photosynthetic efficiency in dynamic light environments as compared to ambient CO2 concentration (AC; 385 umol CO2/ mol) was tested. Sun leaves of European beech (Fagus sylvatica L.) andcurrent-year shoots of Norway spruce (Picea abies (L). Karst.) were exposed to five dynamic light regimes (LRs) occurring within forest canopies due to variable cloud cover or self-shading of leaves and to a steady-state LR. The LRs differed in the timecourse of incident irradiance, whereas the overall duration (600 s) and total amount of radiation (35.88 mmol photons/ m2) were the same in all LRs. The EC treatment enhanced the amount of CO2 assimilated under all LRs tested. While the s
