Main scientific interests:

1. Hormonal regulation of plant development
- verification of the hormonal hypothesis of flowering induction of winter plants
- the search for compounds with regulatory/hormonal nature in plants and study of their activities and mechanisms of action

2. Bioregulators, microelements and maternal effect as factors affecting plant development, yield formation and stress resistance 
- use of bioregulators (zearalenone, brassinosteroids) in crop production
- role of microelements (selene) in plant development and stress resistance
- selected biochemical mechanisms of maternal effect 

3. Physiological and biochemical determinants of biomass production of plants with potential use in industry (Miscanthus giganteus, algae)

4. Lowering of the content of allergens in wheat grains - use of allelopatics and traditional breeding

We offer the following expertise for research projects and cooperation:

1. Measurements of plant chemical composition:
- plant hormones: ethylene, salicylic acid, cytokinins, auxins, poliamines, jasmonic acid
- vitamins: C, E, provitamin A
- other substances: zearalenone, caffeine, melatonin, sugars, proteins, fatty acids, sterols, total lipids, photosynthetic pigments, H2O2, etc.
2. Osmolarity and ion concentration measurements (especially: H+, K+, Na+, Ca2+)
3. Measurements of oxidative stress enzymes activity (SOD, catalase, peroxidase)
4. Measurements of electrolyte leakage and osmotic potential
5. Electric potential measurements of plant tissues and cells
6. Plasmalemma isolation from plant material (two phase system: dextran- polyethylene glycol).
7. Artificial cell membrane creation (mono- and multi layers) as a model to study surface interaction of hydrophilic and hydrophobic compounds (hormones, enzymes).
8. Measurements of plant tissue metabolic activity via calorimetric methods
9. Potentiometric analysis, by ion selective electrode and biosensors, conductometric analysis
10. The algae cultivation under controlled light and temperature conditions, controlling the algae growth to obtain metabolites useful in industry
