Compendium of Plant Science is a comprehensive and well-structured book designed for various competitive examinations conducted by Indian Council of Agricultural Research, Stage Agricultural Universities, Stage Agricultural Department, Public Service Commission and Banking Services. The book brings together key disciplines of plant biology in a systematic manner, making it highly useful for undergraduate and postgraduate students, researchers, and educators in the field of biological and agricultural sciences. Each chapters of the book has been designed in the form of objective questions with answer key. 
The book begins with Cell Biology, introducing the structural and functional organization of plant cells, followed by Cytogenetics, which explains chromosome structure, behavior, and inheritance patterns. Plant Biochemistry and Plant Physiology chapters offer detailed insights into metabolic pathways, enzyme functions, photosynthesis, respiration, and plant growth regulators, forming the biochemical and physiological basis of plant life. A strong foundation in genetics is provided through chapters on Mendelian Genetics, Molecular Biology, and Molecular Genetics, which collectively explain classical inheritance, DNA structure and function, gene expression, and regulation. These chapters bridge traditional genetics with modern molecular approaches. Applied aspects of plant science are covered extensively in chapters on Plant Breeding, Genetic Engineering, and Plant Tissue Culture, highlighting methods used for crop improvement, transgenic development, and in vitro propagation techniques. The inclusion of Microscopy enhances understanding of microscopic tools and techniques essential for plant research.
The book is further enriched with a Glossary for quick reference, Appendices for supplementary information, and a section on Scientific Contribution, which emphasizes the practical and research significance of plant science. Overall, Compendium of Plant Science serves as an integrated, student-friendly, and authoritative resource for mastering both theoretical and applied plant sciences.
