Abstract: This study aims to explore the microstructure, arrangement, and silicon content of Quercus robur leaves grown in shaded and sunlit areas in the southern steppes of Ukraine.The study aimed to identify the similarities and differences in the ultrastructure and silicon content of oak leaf epidermis under varying natural lighting conditions.Electron scanning microscopy and laser confocal microscopy were used.Results indicated that shading alters the ultrastructure of the oak leaf epidermis and its silicon content.Silicon accumulation occurs primarily in the trichomes, stomata, and usual epidermal cells of the oak leaf.The phenotypic plasticity of the studied leaves was evident in reduced leaf size and area and increased trichomes, stomata density, and silicon in the epidermis of leaf trees grown in direct sunlight.This plasticity improves the leaves' ability to absorb and reflect light, allowing for normal growth and function even under direct sunlight.The various features of oak leaves can be employed for practical applications.
