Abstract

Extreme weather events such as droughts have been predicted to increase within the near future and so climate change will most likely threaten agricultural production. Plants live in close relationship with microorganisms and endophytic microorganisms are known to play an essential role in plant resilience to abiotic and biotic stresses. The effect of drought stress on endophytic microorganisms in the roots of barley (Hordeum vulgare) is investigated in this master thesis. Therefore, a field experiment was conducted at the research farm of the University of Innsbruck in Imst (Austria) and a drought scenario was simulated by building a rain shelter. In addition to the determination of agronomic properties, soil samples were investigated for physical, chemical and microbiological parameters. Centrally, roots of barley were collected for cultivation-based and cultivation-independent investigations targeting the endophytic microbiota and its response upon drought stress.
