Three computer controlled Daylight Plant Cuvettes (DPC) were used to investigate the reaction of Pelargonium zonale ‘Präludium’ to partly extreme climate situations.
Net photosynthesis rate and destructive ratings served for a comparison of the respective experiments.
By increasing the CO2- concentration from 400 vpm to 800 vpm a considerably higher net photosynthesis was measured.
Only slight effects were seen by increasing the CO2- concentration to 1,200 vpm.
Reduction of the PPFD led to significantly reduced results at the destructive ratings.
