Effect of season, needle age and elevated CO2 concentration on photosynthesis and Rubisco acclimation in Picea abies

Original language description

We comprehensively studied Rubisco adjustment to EC in coniferous Picea abies using an electrophoretic (protein content), spectrophotometric (initial (RAinitial) and total (RAtotal) in vitro Rubisco activities), and gas-exchange (maximum carboxylation activity in vivo (VCmax)) techniques. With respect to differing carbon sink strength and nitrogen remobilization, we hypothesized greater acclimation of photosynthesis in one-year-old as compared to current-year needles and at the end than at the beginningof the vegetation season. EC treatment led to a decrease in VCmax values in current-year needles, but the ribulose1,5-bis- phosphate (RuBP)-limited rate of photosynthesis (Jmax) remained unaffected. Indeed, both VCmax and Jmax were reduced by the EC treatment in one-year-old needles. The extent of photosynthetic acclimation in EC plants did not increase, however, during the vegetation season. EC decreased the activation state of Rubisco (RAinitial/RAtotal) by 16% and 5% in current-year
