Germination and Reserve Mobilization


Book Description

Seed Physiology, Volume 2, Germination and Reserve Mobilization, addresses some of the major unanswered questions about seed dormancy, germination, and post-germination development of the seedling. The book contains seven chapters and begins with two studies on dormancy—one on the structural constraints to germination and another on metabolic barriers preventing germination. These are followed by separate chapters on the physical and biochemical events following the imbibition of water by dry seeds; the mobilization of polysaccharide reserves from endosperm; the mobilization of nitrogen and phosphorus from external storage tissues; and the mobilization of lipid reserves in seed tissues. The final chapter reviews the subject of embryonic axis-cotyledon interaction, considering mainly those species where the cotyledons are adapted for the storage of reserves. Both this volume and its companion (Seed Physiology Volume 1. Development) will provide a valuable resource for advanced students, teachers, and researchers in plant physiology, biochemistry, agronomy, and related disciplines.

Authored by preeminent authorities in the field, this book is an invaluable resource for researchers, teachers, and students interested in the diverse aspects of seed biology.




Mobilization of Reserves in Germination


Book Description

Although many reviews and articles about germination have been published, our understanding of the process is far from complete. Some of the reactions involved in the transforma tions and translocation of reserve compounds and their final fate in the growing tissues was the subject of the annual symposium of the Phytochemical Society of North America which was held in August, 1982, on the campus of the University of Ottawa, Canada. A major emphasis was on low molecular weight compounds, amino acids and sugars, and the checks and balances operating as they are produced by hydrolysis in reserve tissues and transformed in the growing tissues. The critical role of membranes was given especial emphasis. The closing presentation was an anthropocentric review of the nutritional benefits accrued during germination, and provided a scientific basis for the inclusion of sprouted seedlings in the human diet. Dr. R. G. Fulcher introduced the symposium topic with an elegant histochemical study in which the site and nature of seed reserves were defined by means of the glowing colors of fluorescence microscopy. The symposium was organized by C. Nozzolillo with advice and assistance from fellow PSNA members S. A. Brown, J. T. Arnason, and A. Picman and a visiting scientist from Sweden, C. Liljenberg.




Seed Dormancy, Germination and Pre-Harvest Sprouting


Book Description

Pre-harvest sprouting (PHS) and late-maturity alpha-amylase (LMA) are two of the biggest grain quality defects that grain growers encounter. About 50 percent of the global wheat crop is affected by pre-harvest sprouting to various degrees. Pre-harvest sprouting is a genetically-based quality defect and results in the presence of alpha-amylase in otherwise sound mature grain. It can range from perhaps undetectable to severe damage on grain and is measured by the falling numbers or alpha-amylase activity. This is an international issue, with sprouting damage lowering the value of crops to growers, seed and grain merchants, millers, maltsters, bakers, other processors, and ultimately the consumer. As such it has attracted attention from researchers in many biological and non-biological disciplines. The 13th International Symposium on Pre-Harvest Sprouting in Cereals was held 18-20 September, 2016 in Perth to discuss current findings of grain physiology, genetic pathways, trait expression and screening methods related to pre-harvest sprouting and LMA. This event followed the previous symposium in 2012 in Canada.




Seeds


Book Description

Since the publication of our monograph on seed physiology and biochemistry (The Physiology and Biochemistry of Seeds in Relation to Germination, Sprin ger-Verlag, 1978, 1982), it has been suggested to us that a text covering the same subject area would be appropriate. This book is our response. Unlike the previous volumes, however, this text is not intended to be either a critical or a comprehensive account. Instead it is a more generalized consideration of the essential aspects of seed physiology and biochemistry as we see them. It also includes a substantial amount of new and different material. In a work of this sort it is inevitable that some simplifications must be made, but we hope, never theless, that we have presented the most reasonable conspectus of areas of con troversy and uncertainty. In this respect, literature citations have been kept to a minimum and do not interrupt the text; they are placed at the end of each chapter and are intended to be used as a source for further references. We hope that this book will be of value to students and teachers in uni versities, colleges, and other institutes of higher learning whose courses include plant biology. Although it is particularly appropriate for studies of seed biol ogy, it should also find broader applications in general plant physiology, agri culture, and horticulture.




Recent Advances in the Development and Germination of Seeds


Book Description

These Proceedings are a product of the International Workshop on Seeds held in Williamsburg, Virginia, USA, at the College of William and Mary, during the week of August 6-11, 1989. Sixty-eight participants attended. The location provided a scenic and historical setting for the excellent work presented. Good facilities and amenities also contributed to the success of the meeting. The Proceedings present the substance of the main lectures given at this meeting. In addition, there were 29 brief paper presentations and 30 poster presentations which have been summarized in abstract form in a separate publication. This meeting represents the third such meeting of a diverse group of scientists interested in the behavior of seeds, both in an agricultural sense and as tools for the advancement of more particular s~bject matter. The first meeting was held in Jerusalem, Israel in 1980 and the second in Wageningen, The Netherlands in 1985. A fourth meeting is being planned. The Editor and Organizer wishes to thank not only the contributors to this volume for their efforts but also all the other participants whose combined efforts made this meeting a great success.

Annual Plant Reviews, Seed Development, Dormancy and Germination


Book Description

The formation, dispersal and germination of seeds are crucial stages in the life cycles of gymnosperm and angiosperm plants. The unique properties of seeds, particularly their tolerance to desiccation, their mobility, and their ability to schedule their germination to coincide with times when environmental conditions are favorable to their survival as seedlings, have no doubt contributed significantly to the success of seed-bearing plants. Humans are also dependent upon seeds, which constitute the majority of the world’s staple foods (e.g., cereals and legumes). Seeds are an excellent system for studying fundamental developmental processes in plant biology, as they develop from a single fertilized zygote into an embryo and endosperm, in association with the surrounding maternal tissues. As genetic and molecular approaches have become increasingly powerful tools for biological research, seeds have become an attractive system in which to study a wide array of metabolic processes and regulatory systems. Seed Development, Dormancy and Germination provides a comprehensive overview of seed biology from the point of view of the developmental and regulatory processes that are involved in the transition from a developing seed through dormancy and into germination and seedling growth. It examines the complexity of the environmental, physiological, molecular and genetic interactions that occur through the life cycle of seeds, along with the concepts and approaches used to analyze seed dormancy and germination behavior. It also identifies the current challenges and remaining questions for future research. The book is directed at plant developmental biologists, geneticists, plant breeders, seed biologists and graduate students.
