Paperback. Condizione: New. Print on Demand. This book explores the exciting field of corn breeding, delving into the fascinating ways in which corn can be modified through selective breeding practices. The author, a leading expert in the field, has conducted meticulous experiments to demonstrate how specific physical characteristics of the corn plant can be influenced and altered over generations. The book provides a detailed account of the author's experiments, which focused on modifying the height at which ears grow on the stalk and the angle at which they hang. Through careful selection and breeding, the author successfully created two distinct strains of corn: one with ears positioned high on the stalk and the other with ears that gracefully decline. These experiments not only illustrate the power of selective breeding but also shed light on the underlying genetic mechanisms that control these traits. Beyond the scientific implications, the book also explores the practical considerations and potential applications of these breeding techniques. The author discusses the advantages and disadvantages of high and low ear placement, as well as the role of ear angle in protecting the corn from weather damage and facilitating harvesting. This book is a valuable resource for anyone interested in the science and practice of corn breeding, providing a unique perspective on the remarkable possibilities of manipulating plant traits through selective breeding. It offers a deeper understanding of the genetic basis of plant development and the potential for improving crop yields and quality through targeted breeding programs. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.
