Light as a factor in controlling plant growth and development

For optimal growth and development, plants need to perceive and process information from both their biotic and abiotic environments. A particularly important environmental signal is light, to which plants react differently. Since plants are photosynthetic and immobile, they must show a special sensitivity and reaction in response to the illumination quality and dynamics. The diverse reaction of plants to light requires a complex determination of its intensity, polarization, duration and spectral composition of illumination. The purpose of this report is to present the results of studies of the influence of these various factors on the process of plant development.
