Download or read book Plant Dormancy written by Renato V. Botelho and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dormancy is a mechanism found in several plant species developed through evolution, which allows plants to survive in adverse conditions and ensure their perpetuation. This mechanism, however, can represent a barrier that can compromise the development of the species of interest, and therefore, the success of its cultivation. It is important to understand the causes, effects, and mechanisms, as well as the technologies for overcoming dormancy of buds, seeds, and plant propagules. In this context, this publication has as a main objective of offering an in-depth view of the dormancy process in cultivated plants, based on a survey of more recent international research on the subject. Written by several researchers from different institutions of education and research, this book presents information on the most diverse species of plants of agronomic and forestry interest. In addition to the physiological, biochemical, and genetic aspects, the chapters also address the possible causes of dormancy, as well as technological issues that are essential for the successful cultivation of several economically important species. The focus of this publication is on temperate fruit species. Classical examples of temperate plants that present dormancy are fruit trees such as apple, pear, quince, apricot, and cherry. These pome and stone fruits are typical representatives of a deciduous temperate climate, wherein trees drop their leaves at the end of the reproductive cycle, consequently entering dormancy. Dormancy has its control effected by factors of a hormonal nature, where the hormone promoters and growth inhibitors are balanced. Edaphoclimatic conditions also affect plant dormancy periods, for the most part through temperature changes. Other chapters in this book are dedicated especially to potatoes, vegetables, as well as forest and forage species, which makes this text a complete and comprehensive work on the subject.
Download or read book Annual Plant Reviews Seed Development Dormancy and Germination written by Kent Bradford and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Advances in Plant Dormancy written by James V. Anderson and published by Springer. This book was released on 2015-04-30 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant dormancy involves synchronization of environmental cues with developmental processes to ensure plant survival; however, negative impacts of plant dormancy include pre-harvest sprouting, non-uniform germination of crop and weed seeds, and fruit loss due to inappropriate bud break. Thus, our continued quest to disseminate information is important in moving our understanding of plant dormancy forward and to develop new ideas for improving food, feed, and fiber production and efficient weed control, particularly under global climate change. Proceeding from the 5th International Plant Dormancy Symposium will provide an overview related on our current understanding of how environmental factors impact cellular, molecular, and physiological processes involved in bud and seed dormancy, and perspectives and/or reviews on achievements, which should stimulate new ideas and lines of investigation that increase our understanding of plant dormancy and highlight directions for future research.

Download or read book Seed Dormancy and Germination written by J. W. Bradbeer and published by Springer Science & Business Media. This book was released on 2013-03-13 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: The germination of seeds is a magical event, in which a pinch of dust-like material may give rise to all the power and the beauty of the growing plant. The mechanisms of seed dormancy, of the breaking of seed dormancy and of germination itself continue to remain shrouded in mystery, despite the best efforts of plant scientists. Perhaps we are getting there, but very slowly. This book considers germination and dormancy from the point of view of plant physiology. Plant physiologists attempt to understand the relation ship between plant form and function and to explain, in physical and chemical terms, plant growth and development. The place of germination and dormancy in plant ecophysiology is taken into account with attempts to understand the seed in its 'environment, whether the environment be natural, semi-natural or wholly artificial. In due course plant scientists hope to develop a precise understanding of germination and dormancy in cellular and molecular terms, and therefore there is some biochemistry in this book. Biochemists who wish to learn something about seeds should find this book useful.

Download or read book Seed Dormancy written by Angel J. Matilla and published by MDPI. This book was released on 2020-11-13 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: The appearance of the new generation in higher plants is ensured by the presence of viable seeds in the mother plant. A good number of signaling networks is necessary to provoke germination. Phytohormones play a key role in all stages of seed development, maturation, and dormancy acquisition. The dormancy of some seeds can be relieved through a tightly regulated process called after-ripening (AR) that occurs in viable seeds stored in a dry environment. Although ABA is directly involved in dormancy, recent data suggest that auxin also plays a preponderant role. On the other hand, the participation of reactive oxygen species (ROS) in the life of the seed is becoming increasingly confirmed. ROS accumulate at different stages of the seed’s life and are correlated with a low degree of dormancy. Thus, ROS increase upon AR and dormancy release. In the last decade, the advances in the knowledge of seed life have been noteworthy. In this Special Issue, those processes regulated by DOG1, auxin, and nucleic acid modifications are updated. Likewise, new data on the effect of alternating temperatures (AT) on dormancy release are here present. On the one hand, the transcriptome patterns stimulated at AT that encompasses ethylene and ROS signaling and metabolism together with ABA degradation were also discussed. Finally, it was also suggested that changes in endogenous γ-aminobutyric acid (GABA) may prevent seed germination.

Download or read book Seed Dormancy Germination and Pre Harvest Sprouting written by Chengdao Li and published by Frontiers Media SA. This book was released on 2019-03-28 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Seed Dormancy in Grasses written by G. M. Simpson and published by Cambridge University Press. This book was released on 1990-07-19 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first comprehensive review of the occurrence and explanation of seed dormancy in grasses is presented in this volume. An understanding of seed dormancy is of considerable significance to world agriculture and the global economy, since grasses are a principal source of food for humankind and play an essential role in stabilizing the land surface of much of the globe. Experimental evidence is considered in depth for a single species, the wild oat (Avena fatua), probably the most widely studied species for understanding seed dormancy in the plant kingdom. The evidence for this species is compared with other examples among the Gramineae to reach some general conclusions about the nature of seed dormancy in grasses.
Download or read book Dormancy and Low Growth States in Microbial Disease written by Anthony R. M. Coates and published by Cambridge University Press. This book was released on 2003-06-02 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: All cellular life-forms can exist in replicating and non-replicating states. Organisms replicate only when the conditions are beneficial, and when not replicating they concentrate on survival of these environmental stresses. Many bacteria, harmful to humans, survive the period of infection in a low growth state. This 2003 book addresses the basic science of microbial dormancy and low growth states, putting this in the context of human medicine. Such fundamental topics as bacterial growth and non-growth, culturability and viability are covered, as well as survival of the host's immune response, and inter-bacterial signalling. Following this introduction, more medically focused topics are discussed, namely antibiotic resistance arising during stationary phase, biofilms, the bacteria which cause gastric ulcers and tuberculosis as the classic persistent bacterial infection. This book will interest graduate students and researchers in medical microbiology, immunology and infectious disease medicine who are interested in bacterial dormancy in relation to disease.
Download or read book Seed Dormancy and Germination written by Jose Carlos Jimenez-Lopez and published by BoD – Books on Demand. This book was released on 2020-01-08 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seed dormancy and germination are critical processes for the development of plants. Seed dormancy allows seeds to overcome harsh periods of seedling establishment, and is also important for plant agriculture and crop yield. Several processes are involved in the induction of dormancy and in the shift from the dormant to the germinating state, and hormones and regulatory genetic networks are among the critical factors driving these complex processes. Germination can be prevented by different factors leading to seed dormancy, which is highly dependent on environmental cues. During and after germination, early seedling growth is sustained by catabolism of stored reserves (proteins, lipids, or starch) accumulated during seed maturation, supporting cell morphogenesis, chloroplast development, and root growth until photo-auxotrophic growth can be resumed.
