This 1936 specialized textbook by Professor Leonid Alexandrovich Ivanov is a monumental work in the field of Soviet dendrology and botanical science. The text provides a deep dive into the internal logic of plant life cycles, including the arrangement of 172 detailed technical illustrations that clarify complex physiological processes such as photosynthesis, transpiration, and mineral nutrition specifically tailored for forestry applications. Published during the pre-war period by Goslestekhizdat, this volume reflects the rigorous academic standards of the Leningrad school of forestry. As a vital primary source, it documents the transition of classical plant physiology into practical silviculture and forest management. Ivanov, a leading figure in the physiological study of woody plants, synthesizes vast experimental data to address the specific needs of forest engineering education under the Narkomles USSR. With a limited print run of 5200 copies, this hardcover edition is a significant bibliographical rarity for historians of science, specialists in the history of forestry, and collectors of pre-war Soviet academic imprints.
