Auxins and Plant Growth explores the critical role of auxins in plant physiology and their applications in agricultural technology, emphasizing the need for a strong scientific foundation to drive meaningful advancements. The book provides a comprehensive integration of fundamental knowledge about auxins—how they are formed, their functions, and methods for identification and measurement—with their practical applications in agriculture. It highlights the dangers of research conducted without a solid understanding of auxin physiology and aims to guide researchers in designing effective and scientifically grounded experiments. The author bridges the gap between theory and application, offering insights into the physiological basis of auxin activity and the technological methods derived from it. While not a historical review or a practical manual, the book serves as a resource for graduate students and professionals, encouraging the use of foundational discoveries to achieve systematic advancements in agricultural productivity. Ultimately, the work underscores the importance of integrating science and technology to address the pressing global challenge of increasing agricultural efficiency in a rapidly growing population.
