Book excerpt: Plants, Chemicals and Growth focuses on chemicals that regulate the growth and development of plants. It explores the problems of growth and growth regulation by looking at the roles of chemical substances, natural and synthetic, which affect the behavior of the cells of flowering plants. It also describes the variety of responses triggered by such chemicals, which include herbicides, those that stimulate the rooting of cuttings or cause leaf or fruit abscission, and those associated with fruit setting and artificial parthenocarpy. Comprised of 10 chapters, this volume begins with an overview of examples of chemical regulators and the biological responses they induce in plants, from tropism and chemotropism to nastic responses; rhythmic phenomena in growth and development; initiation of lateral organs and problems of phyllotaxy; periodicities in growth; and effects on the balance between vegetative growth, flowering, and fruiting. It discusses the totipotency and exogenous regulation of cells, history and modern concepts of plant growth regulators, the ways chemicals induce growth in quiescent cells, and growth-regulating effects in free cell systems. The reader is also introduced to biologically active compounds, such as indolyl and triazine compounds; how plant-regulating substances work; concepts and interpretations of plant growth regulation; and problems and prospects of chemical regulation of plant growth and development. This book will be of interest to teachers, biology students, agriculturalists, and researchers.

Available in PDF, EPUB and Kindle. Book excerpt: Introduction When the study of heredity and variation first came to be treated as a scientific subject-and this, one must remember, was only just over a hundred years ago-there was an unfortunate separation between the disciplines of cytology and experimental breeding. This separation was based partly on a lack of understanding and partly on a lack of the desire to understand. Even WILLIAM BATESON, the first apostle of mendelism in England, had a blind spot for cytology and for many years dogmatically refused to believe that MENDEL'S determinants were transmitted and distributed by the chromosomes. This separation between cytology and experimental breeding is one which persists, in a measure, even today, simply because there are two quite different, though complementary, techniques available for the study of heredity and variation. On the one hand, one can study directly the structure and behaviour of the actual vehicles which transmit the genetic determinants from one generation to the next. This is the method employed by those who study genetics through a microscope. The alternative method is that used by the experimental breeder who, in default of being able to watch the hereditary factors segregate from each other directly, is obliged to examine the constitution of the germ cells indirectly by sampling, and usually at random, the products of a controlled mating.

Book excerpt: Plants, Chemicals and Growth investigates natural and synthetic chemicals that control plant growth and development. It examines how plant growth regulators, such as 2,4-D, 2,4-dichlorophenoxyacetic acid, 2,4,5-T, 2,4,5-trichlorophenoxyacetic acid, ammonium sulfamate, indole-3-butyric acid, disodium 3,6-endoxohexahydrophthalate, gibberellic acid, and 2-chloroethyltrimethylammonium chloride, induce biological responses in plants. These responses range from tropism and chemotropism to growth of organs by cell division and enlargement, rhythmic phenomena in growth and development, initiation of lateral organs and problems of phyllotaxy, and the regulatory effects of light and temperature on growth and form. Comprised of 10 chapters, this volume begins with an overview of chemical regulators and the ways in which they elicit biological responses in plants; how chemical regulation of plants is related to the growth and development of flowering plants; cell growth and cell division; cell cycle; and cellular ontogeny. It then looks at the history and modern concepts of growth-regulating compounds, such as auxins, cytokinins, and gibberellins. The book introduces readers to how chemicals induce growth in quiescent cells; natural sources of growth stimulatory substances; synergisms and interactions of growth regulatory systems; growth-regulating effects in free cell systems; examples of biologically active compounds; the mechanisms of action of plant growth regulators; concepts and interpretations of plant growth regulation; and prospects and problems associated with chemical regulation of plant growth and behavior. Teachers, biology students, agriculturalists, and researchers will find this book extremely useful.
