Main fields of interest and research: Plant functioning under abiotic stress conditions – root-to-shoot communication, water relations, photosynthetic efficiency and stomata status under low temperature (chilling, frost), drought and flooding stress conditions in various crop plants, especially wheat, barley, rye, triticale, sorghum, maize, tomato and oilseed rape; Water use efficiency in plants – physiological grounds for improved water use efficiency in crop plants under common and deficit watering; Abscisic acid (ABA) – role of ABA in plant responses to abiotic and biotic stresses as well as in the regulation of the ability of cells and tissues to regenerate plants in vitro.
