Abstract
The depression in CO2 assimilation rate of plants exposed to long-term elevated CO2 may be the consequence of changes in the photochemical reactions leading to an increased sensitivity of the photosynthetic apparatus to high irradiance. Therefore, the effects of elevated CO2 on the light reactions of photosynthesis of Norway spruce during long-term growth in open chambers at ambient and elevated CO2 concentration were studied. A significant depression of PS II to PS I fluorescence emission, an accumulation of inactive PS II reaction centres, and a diminution of LHC II was found in needles exposed to elevated CO,. This all indicates a high-irradiance adaptation and/or stress, thus supporting the hypothesis of an increased susceptibility of the photosynthetic apparatus to high irradiance at elevated CO2.
