Plant Growth Regulators in Agriculture and Horticulture by Amarjit Basra Pdf

As agriculture becomes more mechanized and science increases the possibilities for using inputs to enhance production, the role of PGRs becomes more vital. Plant Growth Regulators in Agriculture and Horticulture provides agriculture professionals and researchers with the information needed to effectively tap these versatile resources to enhance crop production. Through discussions of the “classical five” phytohormones--gibberellins, cytokinins, ethylene, abscisic acid, and auxins--and the growing number of nontraditional PGRs such as oligosaccharins and brassinosteroids, Plant Growth Regulators in Agriculture and Horticulture reviews past and present uses of PGRs in managing crop yield and offers some speculation on future directions. Detailed discussions on the use of PGRs in, for example, grain, ornamental, and citrus crops, introduce readers to strategies for enhancing crop quantity and quality, for improving the postproduction quality of life of perishable plants, and for crop load management, respectively. The book also includes informative visuals, such as tables of common, chemical, and trade names of different commercially available PGRs; diagrams of various PGR processes; as well as before-and-after pictures illustrating the effects of PGRs. Plant Growth Regulators in Agriculture and Horticulture is a comprehensive text covering the role of plant growth regulators in: root formation manipulating yield potential plant stress protection ornamental horticulture postharvest life of ornamentals manipulating fruit development and storage quality citriculture reducing fruit drop bloom-thinning strategies If the history of agriculture, which is over 10,000 years old, was condensed into a twenty-four-hour span, science-based plant breeding would be only about fifteen minutes old. Still, the role of PGRs in agriculture is modest compared to other agrochemicals, such as fungicides, herbicides, and insecticides. Plant Growth Regulators in Agriculture and Horticulture is an invaluable guide to the varied roles filled by PGRs in the attainment of higher-quality, better-yielding crops.

Plant Growth Regulators by L.G. Nickell Pdf

Chemicals that control plant growth have long been treated like a poor re lation of the herbicides yet in one manner of thinking, herbicides them selves are but one facet of the entire picture of plant growth regulation - a major fraction, to be sure, economically. It is now time to recognize that plant growth regulators should occupy an increasingly important role in agriculture. Sufficient numbers of uses having considerable economic re turn have already become established: (a) to increase the latex flow in the rubber trees; (b) to ripen sugarcane; (c) to control sprouting in onions and potatoes; (d) to shorten and strengthen wheat stems to prevent lodging; (e) to prevent premature deterioration; and (f) to permit control of timing for maximum utilization of crops. In addition, as energy becomes more difficult and costly to obtain, plant growth regulators will play an increasingly important role in energy conser vation as a result of increased yields due to their use . . There are a number of ways to present to the reader the role and effec tiveness of plant growth regulators. The one chosen here is to emphasize the effects on plant functions such as the induction of roots, the control of flowering, the control of sex, and the control of aging. Little emphasis has been placed on the basic research that has served as a background for the successes and potential successes discussed herein. N or is much attention paid to the mode of action of the various regulators.

Plant Regulation and World Agriculture by Tom Scott Pdf

By the year 2000, the most critical world problem--as things stand now--will be sustaining the human race. The quality and the availability of food will continue to be central to this issue. However, since the beginning of the final quarter of the twentieth century, few attempts have been made to organize and integrate information applying our knowledge of the regulation of plant growth to the enhancement of the world's yield of food, forage, fiber, and other useful plants. It is appropriate, therefore, to approach a solution to future human needs by combining an area of basic science with a defined and needed application of it. The purpose of this NATO Advanced Study Institute--Plant Regulation and World Agriculture--is reflected in the content of this volume. It covers a wide range of physiological processes including photosynthesis, translocation, seed germination, source sink relationships, water relationships, flowering, fruiting, and adaptations to stress. The identification, chemistry, and bio chemistry of naturally occurring as well as known and new synthetic plant growth regulators are discussed in relation to productivity, growth retardation, and herbicidal activity. Other topics include plant breeding and genetics, tissue culture and its use in the improvement of and the increase in plant varieties, and ecological implications in agriculture. Chapter titles in bold print in the Table of Contents designate keynote presentations for the three major subtopics in Section II.

Plant Growth Regulators (PGRs): Types, Uses and Safety by Qiang-Sheng Wu,Zhang De-jian Pdf

Plant growth regulators consist of organic molecules produced synthetically and used to modulate plant growth. There are several classes of plant growth regulators, including auxin, gibberellin, abscisic acid, cytokinins, salicylic, jasmonic acid and ethylene, as well as more recently investigated brassinosteroids, strigolactones, polyamine, etc. These plant growth regulators have either promoting or inhibitory effects on plant growth and development by means of modification in plant secondary metabolism and gene regulation. Some of plant growth regulators may have safe issues in fields. More attention should be paid in the application of plant growth regulators. Researchers also try to find other regulators to do more field experiments, in order to reduce the amount of organic chemicals (e.g., traditional plant growth regulators) used. This book discusses the function, types, uses and safety of plant growth regulators. The effects of plant growth regulators on horticultural plants are specially introduced in this book. Fly ash and soil mycorrhizal fungi-released glomalin also get a lot of attention in this book.

Chemical Manipulation of Crop Growth and Development by J S McLaren Pdf

Chemical Manipulation of Crop Growth and Development presents a critical review of the plant growth regulators in field crops. It discusses the strategies to discover plant growth regulators for agronomic crops; the methods of modifying stomatal movement; and the possible use of chemicals for photorespiration control. Some of the topics covered in the book are the hormonal control of photosynthesis and assimilate distribution; manipulation of crop growth by ethylene and some implications of the mode of generation; genetic and chemical manipulation of crops to confer tolerance to chemicals; and effects of allelochemicals on crop growth and development. The control of development of potato plant by using endogenous and exogenous growth regulators is covered. The analysis of crop physiology to assess plant growth regulation in sugar beet is also discussed. An in-depth analysis of the influence of auxin antagonists on pod and seed number is provided. The effect of foliar applications of synthetic plant growth regulators on the agronomic characteristics of field-growth corn is presented. A chapter is devoted to the use and effect of cerone in developing winter barley. The book can provide useful information to farmers, botanists, students, and researchers.

Plant Hormones by P.J. Davies Pdf

Plant hormones play a crucial role in controlling the way in which plants growand develop. Whilemetabolism providesthepowerand buildingblocks for plant life, it is the hormones that regulate the speed of growth of the individual parts and integrate these parts to produce the form that we recognize as a plant. In addition, theyplayacontrolling role inthe processes of reproduction. This book is a description ofthese natural chemicals: how they are synthesizedand metabolized; howthey work; whatwe knowoftheir molecular biology; how we measure them; and a description ofsome ofthe roles they play in regulating plant growth and development. Emphasis has also been placed on the new findings on plant hormones deriving from the expanding use ofmolecular biology as a tool to understand these fascinating regulatory molecules. Even at the present time, when the role of genes in regulating all aspects of growth and development is considered of prime importance, it is still clear that the path of development is nonetheless very much under hormonal control, either via changes in hormone levels in response to changes in gene transcription, or with the hormones themselves as regulators ofgene transcription. This is not a conference proceedings, but a selected collection ofnewly written, integrated, illustrated reviews describing our knowledge of plant hormones, and the experimental work that is the foundation of this knowledge.

Plants, Chemicals and Growth by F.C. Steward Pdf

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.

Gibberellins by Nobutaka Takahashi,Bernard O. Phinney,Jake MacMillan Pdf

The cultivation of rice in Japan has suffered from damage caused by baka nae disease, in which rice seedlings show abnormal growth (elongation) as the result of infection by a plant pathogen. Investigation of the taxonomy of this pathogen led to the commencement of gibberellin (GA) research among Japanese plant pathologists, who later identified it as Gibberella jujikuroi, its other name being Fusarium moniliforme. In 1926, Kurosawa demon strated the occurrence of an active principle in the culture media of fungus that showed the same symptoms as those of the rice disease. In 1938, this finding was followed by the successful isolation of the active principles as crystals from the culture filtrate. This was achieved by the Japanese agri cultural chemists Yabuta and Sumiki, of The University of Tokyo, who named these active principles gibberellins A and B. Following World War II, this discovery attracted the interest of scientists around the world, and research on GA was pursued on a worldwide scale. One of the most outstanding discoveries in GA research after the isolation of GA as the metabolite of the plant pathogen must be the isolation and characterization of GAs from tissues of higher plants by the MacMillan group, West and Phinney, and the Tokyo University group in 1958 and 1959. Thus, GAs have been recognized as one of the most important classes of plant hormones.
