Effect of flooding régime on the growth of Carex acuta in a mesocosm experiment
 JANUŠ, Vojtěch
This MCs thesis is part of the Grant Agency of Czech Republic GACR P504/11/1151 The role of plants in bilance of greenhouse gases in Carex fens. The results of this project will serve as a basis for another analyses of greenhouse gases in natural wetland biotops. Growth and morphological changes of Carex acuta were monitored in mesocosm experiment durig the growing seson. Carex acuta has already been the subjekt of numerous studies. The aim of this study is to compare the growth rate of plants C. acuta grown under controlled conditions, simulating different regimes of flooding habitat. Number of shoots and maximum plant height were observed during the growing season. Destructive method has been used to fall aboveground and belowground biomass in autumn. Elevated water levels in the middle of the growing season caused a slowdown in growth in height and the creation of new shoots. Reduced water level of the mid-growing season seemed to faster growth of plants in height. Underground biomass significantly negatively affected by increased water level in the middle of the growing season.
