Název v původním jazyce

Changes in the photosynthetic apparatus of european beech and Norway spruce under long-term exposure to elevated CO2

Popis výsledku v původním jazyce

The changes of photosynthetic performance caused by increasing CO2 concentration are refl ected at diff erent hierarchical levels of photosynthetic apparatus from the effi ciency of individual photosynthetic processes to changes in leaf structure. Th e aim of this study was to elucidate the relationships between the ultrastructure and function of photosynthetic apparatus under elevated CO2 concentration. We studied two common tree species ? the European beech and the Norway spruce ? grown under ambient(AC) and elevated CO2 concentrations (EC). Photosynthetic parameters were obtained using the gas-exchange system LI-6400 (LI-COR, USA). Th e characteristics of chlorophyll a fl uorescence were obtained in vivo with FluorPen FP100max (PSI, CZE) and in vitro polarographically in a suspension of isolated chloroplasts. Non-structural soluble saccharides and starch accumulation was quantifi ed using HPLC. Th e chloroplast ultrastructure was quantifi ed by stereological methods (Ellipse 2.08,
