Plant carbon assimilation is mainly provided by leaf photosynthesis. However, other plant organs, like woody stems are able to photosynthesize. The main goal of this thesis was to investigate the little-studied ecophysiological and biochemical processes of photosynthesis in the young stems of trees. The study particularly focused on the European beech (Fagus sylvatica L. ) and some other temperate tree species. Gas exchange, chlorophyll fluorescence, enzyme activities, chlorophyll and nitrogen content measurements were achieved. Results show an interspecific and a seasonal variability of stem carbon assimilation. Light-saturated gross photosynthesis is positively correlated to the chlorophyll and nitrogen contents. In comparison with leaves...
