We determined pigment contents, rate of photosynthesis and parameters of chlorophyll a fluorescence for sun and shade needles after three seasons of elevated CO2 exposure. The shade needles still profited from elevated CO2 and revealed stimulated electron transport, for the exposed ones the stimulation of both electron transport activity and CO2 assimilation rate under elevated CO2 already disappeared.
