This study demonstrates the potential of investigating and analyzing the anatomical structure of Miscanthus × giganteus (Giant Miscanthus) leaves using light microscopy with the OpenFlexure Microscope. Research on this crop is crucial for understanding its morphological and physiological characteristics, which influence productivity and adaptation to diverse growing conditions. Key features of leaf structure, including the epidermis, stomatal apparatus, and vascular system, determine the efficiency of photosynthesis, transpiration, and the accumulation of pollutants. These factors are essential for enhancing the productivity of this crop and optimizing its use in ecological projects, particularly in phytoremediation. Accessible, functional, and high-precision tools are essential for the anatomical analysis of plants. The OpenFlexure Microscope facilitates high-resolution imaging and detailed examination of cellular structures in leaves, such as the epidermis, mesophyll, and veins, as well as their interactions. With its 3D-printed design and integration with digital imaging technologies, the OpenFlexure Microscope enhances access to microscopy, even in laboratories with limited resources or in field-based studies. This article presents the anatomical features of Miscanthus × giganteus leaves, which are critical for further breeding and agronomic research. The advantages of using the OpenFlexure Microscope in botanical studies are highlighted, particularly in the examination of plants with complex morphological structures. The method allows for a comprehensive analysis of both microscopic and macroscopic leaf characteristics. The findings indicate that the leaf structure of Miscanthus × giganteus is well-adapted to various climatic conditions, contributing to the plant’s resilience to stress factors. The study concludes that analyzing leaf anatomy is essential for advancing knowledge of the growth and development mechanisms of this crop. The results could contribute to the improvement of breeding programs and the development of effective cultivation strategies for Miscanthus in environmentally challenging sites. Thus, the anatomical study of Miscanthus × giganteus using the OpenFlexure Microscope represents an important step toward optimizing its use as an energy crop and a phytoremediation tool. This approach combines economic benefits, ecological sustainability, and scientific innovation, addressing contemporary challenges in energy and environmental science. Integrating the OpenFlexure Microscope into research in Ukraine could significantly enhance local scientific capacity, improve the accessibility of modern tools for plant analysis, and provide higher-quality data for bioenergy and agricultural research.
