Název v původním jazyce

The impact of long-term CO2 enrichment on sun and shade needles of Norway spruce (Picea abies): Photosynthetic performance, needle anatomy and phenolics accumulation

Popis výsledku v původním jazyce

Norway spruce (Picea abies L Karst) grown under ambient (365-377 mu mol (CO2) mol(-1): AC) and elevated (700 mu mol (CO2) mol(-1); EC) CO2 concentrations within glass domes with automatically adjustable windows and on an open-air control site were studied after 8 years of treatment. The effect of EC on photosynthesis, mesophyll structure and phenolics accumulation in sun and shade needles was examined. Photosynthetic assimilation and dark respiration rates were measured gasometrically; the structural parameters of mesophyll were determined using confocal microscopy and stereological methods. The contents of total soluble phenolics and lignin were assessed spectrophotometrically, and localizations of different phenolic groups were detected histochemically on needle cross-sections. EC enhanced the light-saturated CO2 assimilation rate and reduced dark respiration in the current-year needles. No effects of CO2 enrichment on mesophyll structural parameters were observed. Similarly, the acc
