Acclimation of photosystem 2 function of Norway spruce induced during first season under elevated CO2 in lamellar domes
Original language description
Since July 28th, 1997 the two experimental mini-stands of young Norway spruce [Picea abies (L.) Karst.] have been grown in lamellar domes at ambient (AC) and elevated concentration of CO2 [EC, i.e., ambient + 350 umol(CO)mol-1]. Before the start of exposure to EC (June 1997) the dependencies of photosystem 2 (PS2) quantum yield (Y) on irradiance, estimating the efficiency of PPFD utilisation in PS2 photochemistry, were the same for AC and EC shoots. After one month of EC simulation (August 1997), Y values were higher for EC needles as compared with the AC ones (by 1-42%), whereas two months later (October 1997) an opposite effect was observed (decrease of Y by from 1 to 33%) By chlorophyll a (Chl a) fluorescence induction the effects of EC on PS2 function were further characterised.
