Plant Growth Substances


Book Description

In a convenient, single-source reference, this book examines plant growth substances and their relationship to a wide range of physiological processes, ranging from seed germination through the death of the plant. If offers a clear illustration of the pragmatic uses of plant substances in agriculture and demonstrates how basic laboratory research has translated into increased production and profit for the grower. This work begins by building a solid foundation in the subject, which contains historical aspects and fundamental concepts, and provides a methodology for extraction, purification, and quantification of plant growth substances. This forms the basis for understanding the ensuing chapters that explore the many processes involving plant growth substances, including: * seed germination * seedling growth * rooting * dormancy * juvenility * maturity * senescence * flowering * abscission * fruit set * fruit growth * fruit development * premature drop * ripening * promotion of fruit drop * tuberization * photsynthesis * weed control. Providing a detailed examination of plant growth substances and their relationships to specific physiological plant processes, Plant Growth Substances gives students, researchers, and professionals a much needed reference.




Plant Growth Regulating Chemicals


Book Description

The purpose of this two-volume work is to make available both to the investigator and user, on a crop by crop basis, the latest information on the use of chemicals to regulate plant growth and development. Emphasis is given to the major crops and to those which the most success has been achieved.

Biological Approaches to Regenerative Soil Systems


Book Description

Agriculture in the 21st century will need considerable modification to remain both productive and sustainable. Greater production is needed to meet the needs of our still-growing populations and to combat hunger and poverty. Declines in soil health and the pollution of water sources are making many of our production systems less tenable. These adverse trends are exacerbated more and more by the impacts of climate change. There are, fortunately, alternative methods available for agricultural practice that can countervail these constraints. Biological Approaches to Regenerative Soil Systems brings together the work of both researchers and practitioners to map out better approaches to contemporary agriculture that draw upon both old and new knowledge. It presents the science that underlies more biologically driven strategies as well as contemporary innovative experiences in diverse parts of the world. Both accepted research and these varied experiences encourage confidence that these approaches, not relying primarily on the introduction of new varieties and on exogenous inputs, can succeed. This book updates and revises a preceding volume Biological Approaches to Sustainable Soil Systems published by CRC Press in 2006. So much has been learned and done on this subject in the past decade and a half that a second edition was warranted. For instance, the first edition was published, knowledge about plant-soil microbiomes, which are a frequent focus in this book, has mushroomed. Because sustainability is a broad term and an end-state, the editors preferred to assemble expertise regarding regenerative agriculture, which is concerned with the means for achieving sustainability. The concept of regenerative soil systems, entities that are more complex and multifaceted than "soil" alone, also incorporates a concern with having more resilient agricultural systems, ones that are better able to cope with the multiple stresses of climate change that are foreseen for the decades ahead. The book’s chapters representing a wide range of disciplines were contributed by 84 scientists and practitioners from 20 countries. Although they come from persons with in-depth knowledge of their respective fields, the chapters are written to be accessible to readers who are not trained in the specialized subjects. Taken together, the chapters provide students, researchers, practitioners, planners, and policy makers with a comprehensive understanding of both the science and the steps needed to regenerate and sustain soil systems around the world for the long-term benefit of humankind and the environment.

Salicylic Acid - A Versatile Plant Growth Regulator


Book Description

Phytohormones are known to affect the growth and development of plant directly as well as indirectly. Salicylic acid (SA) is a phenolic phytohormone which induces systemic resistance in plants and also regulates defence responses. The derivatives of SA also play an important role in the regulation of various physiological and developmental processes in plants under normal and stressful environmental conditions. SA regulates seed germination, photosynthesis, ethylene biosynthesis, enzyme activities, nutrition, flowering, legume nodulation and overall growth and development of plant. Recently, advancement in elucidating the specific pathways of SA signal transduction has been noticed which helps in understanding the expression of specific genes associated with different developmental programs. The horizon of SA-mediated regulation of various physiological processes has also expanded, and various studies enumerating the efficacy of exogenously applied SA in practical agriculture have also been documented. Therefore, information regarding such recent developments needs to be compiled in the form of a book. This book aims to provide a collective information regarding SA which makes it a versatile plant growth regulator. The chapters included both theoretical and practical aspects that could be of immense use for researches and possible significant developments in future. It is intended that this book will be a help for students, teachers, and researchers, in understanding the relation between the phytohormone and agricultural sciences.




Plant Growth Regulators in Tropical and Sub-tropical Fruit Crops


Book Description

Plant growth regulators or plant bio-regulators have emerged as a powerful tool for improving the performance of horticultural crops in general and fruit crops in particular. This book provided recent information on role of plant hormones, how their concentrations are regulated, and how they modulate the various plant processes. ‘Plant Growth Regulators in Tropical, Sub-tropical Fruit Crops’ is a comprehensive book covering function of plant growth regulators in propagation including micro-propagation, growth, flowering and fruiting behaviour, yield, quality, shelf life and stress management etc. This book has 26 chapters covering most of the tropical and sub-tropical fruit crops like aonla, avocado, banana, ber, citrus, custard apple, date palm, fig, grape, guava, jamun, kokam, litchi, mango, mulberry, papaya, passion fruit, sapota, phalsa, pomegranate and strawberry. Note: T&F does not sell or distribute the Hardback in India, Pakistan, Nepal, Bhutan, Bangladesh and Sri Lanka.




Sustainable Seaweed Technologies


Book Description

Sustainable Seaweed Technologies: Cultivation, Biorefinery, and Applications collates key background information on efficient cultivation and biorefinery of seaweeds, combining underlying chemistry and methodology with industry experience. Beginning with a review of the opportunities for seaweed biorefinery and the varied components and properties of macroalgae, the book then reviews all the key steps needed for industrial applications, from its cultivation, collection and processing, to extraction techniques, concentration and purification. A range of important applications are then discussed, including the production of energy and novel materials from seaweed, before a set of illustrative case studies shows how these various stages work in practice. Drawing on the expert knowledge of a global team of editors and authors, this book is a practical resource for both researchers and businesses who currently work with macroalgae. - Highlights the specific challenges and benefits of developing seaweed for sustainable products - Presents useful case studies that demonstrate varied approaches and methodologies in practice - Covers the complete seaweed chain, from cultivation to waste management
