Poster overview of the Department of Ecophysiology.



The main research area is integrated physiology of key crops at the level of the organism, organs and processes as well as their interaction with environmental conditions:

● daily changes of leaf gas exchange parameters, leaf water relations, chlorophyll a fluorescence parameters, and membrane injury in plants subjected to various abiotic stresses

● preparation and implementation of physiological and laboratory tests for the assessment of crop sensitivity to shortage (drought) and excess (flooding) of soil water as well as multistress interaction of these factors with soil compaction stress

● quantitative and qualitative analysis of root system structure of seedlings and the impact of drought, flooding, and soil compaction stresses on root architecture

● root-to-shoot communication, hormonal balance (abscisic acid (ABA), cytokinins, ethylene, and 1-aminocyclopropane-1-carboxylic acid (ACC, ethylene's precursor)) under drought, flooding, and low temperature (chilling, freezing) stresses

● role of abscisic acid (ABA) in plant reactions to abiotic and biotic stresses as well as in the regulation of the cell and tissue capacity for in vitro plant regeneration

● phenolics as plant photoprotectants, antioxidants, and hydrophobic stabilizers of cell wall under soil drought
