Abstract

Photosynthetic active pigments content (chlorophylls and carotenoids) in Norway spruce (Picea abies) needles was measured by absorption spectroscopy. Norway spruce was exposed to low and high photosynthetic active radiation and ambient and elevated CO2 concentration. It was investigated that combination of low photosynthetic active radiation and elevated concentration of CO2 resulted in stimulation of chlorophylls and carotenoids production. Combination of high photosynthetic active radiation and elevated CO2 concentration led to overall chlorophylls and carotenoids content decrease. Moreover, specific leaf area trend could be used as a potentially reliable indicator of plant stress response.
