Major Fields of Scientific Research:

At last years in the Lab Photobiophysics a biophysical approach for multi-parametric estimation of the physiological state and stress reaction in plants at in vivo and in situ conditions has been developed. The approach is based on measuring and analysis of luminescent and optical signals emitted from the leaf surface. The most efficient way to receive information from plant living tissues about photosynthetic reactions is an analysis of light induced transients of prompt and delayed chlorophyll fluorescence (see the Figure). They provide information about quantum efficiency and electron transport rate in different sites of the photosynthetic electron transport chain, as well as about the collection and redistribution of light energy in the photosystem II antenna complexes. For prompt fluorescence signal analysis the approach known as JIP-test was used. To link data from induction curves of prompt and delayed chlorophyll a fluorescence and of 820 nm light reflection with general physiological characteristics of plants an approach was developed. It is based on the artificial neural networks, which are capable to recognize the taxonomic classification of the plant or the level of water stress in the leaves with high level of confidence.

Since the method is non-invasive and highly informative, it has become a powerful tool for photosynthetic researches at in vivo conditions and it is perspective for environmental monitoring of plant ecosystems. It allows to link genotype (taxonomical and functional) characteristics of the plant samples to their phenotype, expressed by the values of a group of experimental parameters as a kind of “barcode” that uniquely represent the functional state of the investigated plant species.
