Physiology ; ecophysiology ; photosynthesis ; carbohydrate metabolism
Carbon metabolism of leaves, flowers and fruits: photosynthesis, respiration, PSI and PSII activity, carbohydrate metabolism, gene expression.
Physiology of stress: stress biotic (Botrytis cinerea and other, bacteria) and abiotic (pesticides, UV, cold, warm): impact on defence mechanism of the plant and carbon metabolism.
Biomarkers of stress, early detection of the disease symptoms: photosynthesis, chlorophyll fluorescence, biochemical markers, immunity of plants, resistance against pathogens.
