Abstract

Abstract Lobelia dortmanna L. is probably unable to utilize HCO3−and uses only free CO2 for photosynthesis as shown by the Winkler method. A 14C technique was used to show that if CO2 is added to the water around roots, photosynthesis increases 3–5 times more than when the corresponding amount of CO2 is added to the water surroundings the leaves. As the CO2 content in lakes where Lobelia grows is very limited, Lobelia must absorb CO2 from the sediment, and the carbon dioxide will have to diffuse from the roots up into the leaves through the intercellular system of the plant. In conjunction with Lobelia's CO2 uptake from the sediment O2 is liberated. The plant, therefore, acts as an oxygen pump, which oxidizes the sediment down to a depth of 20 cm.
