Growth under elevated CO2 concentration affects the temperature response of photosynthetic rate

Popis výsledku v původním jazyce

In this study, we tested the hypothesis that an elevated CO2 concentration leads to a shift of the temperature optimum of the photosynthetic rate in trees. Since the elevated CO2 treatment usually leads to a significant decrease in stomatal conductance and consequently to decrease in transpiration followed by an increase in leaf temperature, we hypothesized that elevated CO2 results in the acclimation of photosynthetic apparatus to the higher temperature. We studied the two most common species in the Czech Republic ? European beech (Fagus sylvatica L.) and Norway spruce (Picea abies (L.) Karsten). The eight-year-old trees were grown in glass domes at the experimental research site Bílý Kříž in the Beskydy Mts. and they were exposed to ambient (AC; 385?mol CO2 mol-1) and elevated CO2 concentrations (EC; 700 ?mol CO2 mol-1). Based on the gas-exchange and fluorescence techniques we determined the basic photosynthetic characteristics in the range of leaf temperatures from 10 to 45 °C. The
