Available in PDF, EPUB and Kindle. Book excerpt: From prehistoric times man has had a pecial s relationship with seed plants - as a source of food, materials for tools, buildings, clothing and pharmaceuticals, and for ornamenting his surroundings for his own delight (probably in that chronological order which, incidentally, also gives some indication ofthe priorities oflife). Today man's most important staple foods are derived directly from seeds as they have been since neolithic times. (It is a sobering thought, as Harlan* has pointed out, that nothing significant has been added to his diet since then. ) From those times he must have learned to collect, conserve and cultivate seeds; and the accumulated experience has been handed down. This book then is part of an ancient tradition, for here we are still primarily concerned with these skills. Seeds are plant propagules comprised of embryos in which growth has been suspended, usually supplied with their own food reserves and protected by special covering layers. Typically they are relatively dry structures compared with other plant tissues and, in this condi tion) they are resistant to the ravages of time and their environment. But resistant is a relative tenn and seeds do deteriorate: the type, the extent and the rapidity of the deterioration, and the factors which control it are important to agronomists, horticulturalists, plant breeders, seedsmen, seed analysts, and those concerned with the conservation of genetic resources.

Download or read book Seed Biology written by T.T. Kozlowski and published by Elsevier. This book was released on 2012-12-02 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seed Biology, Volume I: Importance, Development, and Germination is a part of a three-volume treatise, which aims to bring together a large body of important information on seed biology. Organized into six chapters, this book begins with a discussion on the importance and characteristics of seeds. Separate chapters follow that discuss the development of gymnosperm and angiosperm seeds, as well as the anatomical mechanisms of seed dispersal. Other chapters focus on the morphogenetic events involved in the germination and the scientific basis for the concept of physiological predetermination or seedling vigor, including the potential application of this concept in agriculture, forestry, and management of natural resources. This work will be useful to various groups of research biologists and teachers, including plant anatomists, pathologists, and physiologists as well as agronomists, biochemists, ecologists, entomologists, foresters, and horticulturists.

Book Synopsis Seed Dormancy and Germination by : J. W. Bradbeer
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.

Book Synopsis Seed Ageing Effects on Ornamental Seed Germination and Post-Germinative Growth and Comparison of Seed Vigor Tests by : Xiaolei Hu
Download or read book Seed Ageing Effects on Ornamental Seed Germination and Post-Germinative Growth and Comparison of Seed Vigor Tests written by Xiaolei Hu and published by . This book was released on 2006 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: During storage, seed ageing is constantly occurring, leading to reductions in seed quality and field emergence and causing economic loss. Intensive research on the mechanism of seed germination and seed deterioration has been conducted in the past three decades; however, seed ageing effects on seedling growth remain to be studied. Nowadays, seeds are transported and traded globally; however, information about seed quality tests is scarce, especially for ornamental species. In this thesis, seed ageing effects on the germination and seedling growth of Salvia splendens and Lactuca sativa seeds were studied. Seeds were subjected to the ageing conditions of 85% RH and 41°C for specified time (2 and 3d for salvia, 5 and 7d for lettuce seeds). Quality testing determined that seed quality, defined by the standard germination test (SG), germination rate (GR) and Seed Vigor Imaging System (SVIS), was significantly reduced after ageing. Results showed that seed germination of all species/varieties tested was delayed after ageing, and gibberellic acid did not rescue the delay of aged seed germination or advance the germination process of unaged seeds, thus disproving the conclusion that GA initiates seed germination. Hypocotyl growth of salvia seedlings was recorded, including the measurement of cell wall extensibility, osmotic potential and turgor pressure, and cell expansion. Results indicated that ageing treatments did not affect the cellular biochemistry governing cell growth after seed germination. Records of seedling growth after ageing confirmed that post-germinative growth was not affected by ageing treatments until a critical point, below which permanent damage took place inside seeds and affected both seed germination and seedling development. Using computerized imaging technology, the Seed Vigor Imaging System (SVIS) was developed at The Ohio State University. Its application was extended to the quality assessment of ornamental species and compared with other traditional tests, i.e., standard germination test, germination rate and accelerated aging test. Results indicated that the double-stress test (germination rate following ageing) was best for detecting change in seed quality, followed by germination rate and the accelerated ageing test. SVIS needed to be adjusted for each individual species. Continuous improvement of SVIS for ornamental species is required to enhance its capability as a vigor test.
Book Synopsis Biostimulants for Crops from Seed Germination to Plant Development by : Shubhpriya Gupta
Download or read book Biostimulants for Crops from Seed Germination to Plant Development written by Shubhpriya Gupta and published by Academic Press. This book was released on 2021-06-23 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biostimulants for crops from seed germination to plant development focuses on the effects and roles of natural biostimulants in every aspect of plant growth development to reduce the use of harmful chemical fertilizers and pesticides. Biostimulants are a group of substances of natural origin that offer a potential to reduce the dependency on harmful chemical fertilizers causing environmental degradation. While there is extensive literature on biostimulants, there remains a gap in understanding how natural biostimulants work and their practical application. This book fills that gap, presenting the ways in which biostimulants enhance seed vigor and plant productivity by looking into their mode of action, an area still being researched for deeper understanding. Exploring the roles of seed germination, pollen tube formation, pollen-pistil interaction, flower and fruit setting, to plant pigments, rhizospheric and soil microorganisms, the book also sheds light on the challenges and realistic opportunities for the use of natural biostimulants. - Approaches biostimulant research with the goal of transforming scientific research into practical application - Includes real-world examples from laboratory, greenhouse and field experiments - Presents the biochemical, physiological and molecular mode of action of biostimulants
