Among the many factors that affect the life of all plant organisms and crops in particular, solar energy is one of the most significant. Nutrients, sufficient air and moisture cannot fully ensure the harmonious development of plants. It is photons, particles of light, that are the energy source of photosynthesis - the most important process that occurs in plants, as a result of which organic compounds are formed from carbon dioxide, water and minerals. In addition, plants use sunlight as a source of information.

As a result of long-term experiments and observations, scientists were able to establish that by regulating such high-quality indicators of light radiation as spectral composition, intensity, exposure time (photoperiod), dose and nature (pulse or continuous light) of radiation, an increase in crop yield by 30% can be stimulated. It was also noted that radiation polarization also has a certain biostimulatory effect on plants. But beyond understanding, mechanisms remained to determine the effect of radiation polarization on plants. We drew attention to the fact that plant leaves are a complex multilayer and multicellular structure with a certain anisotropy of mechanical stress, which can cause anisotropy of their optical properties. A special place in this system is occupied by the layer of the epidermis of plant leaves [1].

The purpose of this report is to discuss issues aimed at understanding the role of the leaf epidermis in the interaction of low-intensity polarized laser radiation with plants, which may cause the regulation of some stages of their development.
