Paperback. Condizione: New. Print on Demand. The lively debate of the impact of crossbreeding on evolution and plant breeding that gripped scientists in the late 19th and early 20th centuries is covered in this book. Plant scientists of the time were observing increases in plant size and vigor through crossbreeding, and pondering on the larger evolutionary implications of these observations. Scientists such as Darwin and Focke were also interested in the converse situation of inbreeding, and were curious as to whether inbreeding had the negative effects on health and vigor that they had observed in humans and other animals. This book draws upon the work of these scientists and the author's own extensive experiments with maize and the genus Nicotiana to provide a robust examination of these phenomena, proposing that the vigor of crossbred plants is due to heterozygosis, while the reduced vigor of inbred plants results from the elimination of heterozygous genes. The book provides a timely review of a pivotal topic in the history of plant science that is still as relevant and intriguing to scientists today as it was 100 years ago.

Paperback. Condizione: New. Print on Demand. This book analyzes key fundamentals of tobacco breeding, offering practical strategies for both scientific and commercial purposes. The author delves into the substantial role that inbreeding has in the enhancement of tobacco's overall growth habit. In contrast, crossbreeding is shown to hold benefits for improving the quality and yield. In highlighting key genetic principles, this book establishes a framework for understanding the inheritance patterns of desirable traits in tobacco plants. The author emphasizes eliminating unfavorable external factors, from soil conditions to harvesting methods, to ensure a quality crop. Ultimately, this book provides valuable insights for harnessing genetic principles to cultivate tobacco with enhanced characteristics, contributing to the advancement of the tobacco industry.

Paperback. Condizione: New. Print on Demand. This book delves into the fascinating world of water purification, a topic that has captivated scientists and public health officials for centuries. The author examines the natural processes by which rivers and streams cleanse themselves, exploring the role of dissolved oxygen in this vital function. The text traces the history of scientific thought on water purity, from early theories emphasizing simple oxidation and dilution to the more sophisticated understanding of the intricate interplay of bacteria and dissolved oxygen. The author presents a detailed examination of the scientific methods used to measure dissolved oxygen levels and discusses the impact of various factors, including temperature and the presence of specific salts, on this crucial indicator of water quality. The book also offers a glimpse into the early stages of bacteriology and the emerging understanding of the role of microorganisms in both polluting and purifying water. By exploring the relationship between dissolved oxygen levels and the growth of bacteria, the author provides a powerful framework for understanding the complex dynamics of water quality and its implications for human health. This insightful work, rooted in careful scientific observation and experimentation, offers a compelling perspective on the crucial importance of understanding and protecting our most precious resource.

Paperback. Condizione: New. Print on Demand. This book explores the inheritance of characters in maize plants, based on extensive pedigree culture work. At the start of the 20th century, the author re-examined the principles of Gregor Mendel through experiments with maize and its various forms. Unlike Gregor Mendel's pea plant experiments, maize presented considerably more variables, making the analysis of the results a more complex process. Nevertheless, the author's findings supported Mendel's principles of heredity while shedding light on additional concepts relating to inheritance and genetic variation. The author discusses unit characters, allelomorphic pairs, complex characters, and the behavior of these units in heredity. Extensive data gathered from the study of various maize characters â" including starchiness, yellow endosperm, aleurone color, podded and podless maize, pericarp color, cob color, silk color, glume color, red sap color, size dimensions, number of rows, and heights of plants, among others â" is presented and analyzed to support the author's conclusions. The book also examines abnormal plant forms and provides a broader analysis of the nature of plant variation and the principles of inheritance. This book provides valuable insights into genetics, particularly for those interested in plant breeding and the history of genetics. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
