Wet grasslands play an important role in the preservation of biodiversity and food production, as they serve as habitat of many birds, insects and other plant species and provide food for farm animals. However, climate change is predicted to affect these wetlands significantly. Therefore, it is important to fully understand the mechanisms of such ecosystems.
In this thesis, the effect of fertilization and cutting of the plants on net photosynthesis rate, biomass production and chlorophyll fluorescens of plants of two different plant functional types (PFT) was investigated. The grasses C. canescens, a representative of conservative PFT and P. arundinacea, a competitive species, were used to gain a better understanding on how plants of these PFTs respond to changing environmental conditions and management regimes.
We will show that the photosynthesis capacity can differ within the same plant species under different management regimes (water and nutrition level). Additionally, we found that midday depression strongly and significantly influences chlorophyll fluorescens in a way that fertilization treatments can be neglected.

Prof Grubhoffer welcomed the student and commission members; all the commission members were present. The student presented the theoretical background of her work on the studied topic, followed by the experimental part, the results, and the conclusions. The supervisor and the opponent presented their reviews. The student answered all the questions of the opponent and also questions from the commission members on the mesocosm, experiment planning and evaluation.
