Abstract
One representative species of each of the three photosynthetic pathways (C3, C4, CAM) were cultivated in growth chambers with high and low nitrogen nutrition level respectively once at 20°C day/13°C night temperature, once at 30°C day/13°C night. Leaf conductances and δ13C values of the leaves of each plant were determined. At 20°C day temperature the C3 species showed higher leaf conductance with low nitrogen nutrition level than with high nitrogen level, which is also reflected in a more negative δ13C value, whereas both C4 and CAM plants did not respond in this manner to nitrogen supply. An increase of day temperature to 30°C diminished the significant response of the C3 plant, while the response of C4 and CAM representatives to nitrogen nutrition did not change markedly.Keywords
