O článku:
The scope of the presented study is the role of plant roots in movement of water in soil - plant - atmosphere continuum and its modelling. The outcomes are product of long-term collaboration between the Institute of Hydraulics and Rural Water Management, BOKU Vienna and the Institute of Hydrology, Bratislava. In the frame of this cooperation, there were three joint missions conducted. During this research work, seasonal changes in root distributions profiles of three cereals crops grown on fields nearby Bratislava were determined. Next, an obtained range of root morphological parameter was applied for simulations of water uptake rate using own modelling tools. The results of root uptake conceptualization and the simulations showed the usefulness of this approach, but there was still a need for further development, in order to progress the model for specific applications in the field of root research. Handling with flexible root distribution function and uptake rate and compensatory mechanisms for water were objectives of the third mission. The addressed research questions and the most important results and outputs of the join studies are presented and discussed in detail.
