Download or read book Plants Chemicals and Growth written by F.C. Steward and published by Elsevier. This book was released on 2012-12-02 with total page 247 pages. Available in PDF, EPUB and Kindle. 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.

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.

Download or read book New Developments in the Biology of Chrysomelidae written by Pierre Jolivet and published by BRILL. This book was released on 2021-10-25 with total page 824 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes what is actually known about the biology of Leaf Beetles. It is the most recent study in the field. As we are well aware, Chrysomelidae, one of the three largest families of beetles, are of great economic importance since they can be a serious pest to crops or, on the other hand, can be used to destroy imported weeds. This is due to the selectivity of their feeding preferences. In this way, Chrysomelidae are an invaluable tool for studying plant selection mechanisms. The many and varied topics dealt with in this book cover almost all aspects of phylogeny, classification, paleontology, parasitology, biogeography, defenses, population biology, genetics and biological control as well as many other subjects. The most renowned specialists in these fields have been chosen to put together a diverse, state-of-the-art publication. Few beetle families have been studied in such detail as the Chrysomelids. This is not only due to their economic importance, but also to their incredible variety of forms and behaviors. There are no less than 40,000 species currently in existence worldwide, but probably 100,000 species have existed since the Jurassic, when they first came into being with the Cycadoids and other primitive plant families, later to diversify during the Cretaceous with the advent of flowering plants.

Download or read book Yvain written by Chretien de Troyes and published by Yale University Press. This book was released on 1987-09-10 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: The twelfth-century French poet Chrétien de Troyes is a major figure in European literature. His courtly romances fathered the Arthurian tradition and influenced countless other poets in England as well as on the continent. Yet because of the difficulty of capturing his swift-moving style in translation, English-speaking audiences are largely unfamiliar with the pleasures of reading his poems. Now, for the first time, an experienced translator of medieval verse who is himself a poet provides a translation of Chrétien’s major poem, Yvain, in verse that fully and satisfyingly captures the movement, the sense, and the spirit of the Old French original. Yvain is a courtly romance with a moral tenor; it is ironic and sometimes bawdy; the poetry is crisp and vivid. In addition, the psychological and the socio-historical perceptions of the poem are of profound literary and historical importance, for it evokes the emotions and the values of a flourishing, vibrant medieval past.
