| seed anatomy ppt: Seed Dormancy and Germination J. W. Bradbeer, 2013-03-13 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. |

| seed anatomy ppt: Advances in Seed Priming Amitava Rakshit, Harikesh Bahadur Singh, 2018-06-07 Most crop plants grow in environments that are suboptimal, which prevents the plants from attaining their full genetic potential for growth and reproduction. Stress due to abiotic and biotic agents has a significant effect on world food production. Annually, an estimated 15% of global yields are lost, but this figure belies far greater losses for specific food systems and the people whose existence is dependent upon them, particularly in developing countries. Current efforts to mitigate these losses are worryingly over-reliant on the use of sophisticated and costly chemicals /measures with substantial economic and environmental costs, or on the development of efficient and smart crop varieties, which can take decades. What we need is a broad range of safe, robust and equitable solutions for food producers. One under-investigated approach is that of utilizing the crop plant’s innate immune system to resist stress. More specifically, the innate immune system can be sensitized or ‘primed’ to respond more quickly and strongly to protect the plant against stresses. However, a strategy of employing priming in combination with reduced pesticide use can enhance protection, and help to meet commitments to reducing chemical inputs in agriculture. This book discusses in detail different segments of priming in addressing stress factors and traits to increase competitiveness against all odds. Adopting a holistic and systematic approach, it addresses priming to counter climate-change related adverse effects coupled with pest and pathogen related stress on the productivity of crops utilizing natural resources to reap sustainable environmental, economic and social benefits for potential productivity of crops, maintaining synergy between soil, water and plants in ways that mimic nature. |

| seed anatomy ppt: Plant Microtechniques and Protocols Edward Chee Tak Yeung, Claudio Stasolla, Michael John Sumner, Bing Quan Huang, 2015-09-19 A proper understanding of the structural organization of the plant body is essential to any study in plant biology. Experimental studies in vivo and in situ will lead to structural, physiological, and cellular changes of the experimental material. To study macroscopic and microscopic changes, different histological methods and microtechniques can be used as they provide valuable information of the experimental system. In addition, the observed structural changes allow investigators to set hypothesis for further studies based on one’s own observation. Thus, proper selection and utilization of microtechniques are a must for the success of a research program. At present, an up-to-date collection of protocols are not readily available in the literature. The latest work in plant microtechniques was published in 1999 by Ruzin but many others are no longer in print [e.g., Jensen (1964); O’Brien and McCully (1981)]. Furthermore, a majority of published works focus on techniques related to general processing and staining procedures. A comprehensive treatment that encompasses broader applications of microtechniques to other disciplines is lacking [e.g., archeology, wood science, etc.]. There is a need to create a comprehensive volume of botanical methods and protocols which includes traditional and novel techniques that can be used by researchers in plant science and investigators in other disciplines that require plant microtechniques in their research and teaching. This book covers a wide variety of applications and brings them up-to-date to make them understandable and relevant, especially to students using the methods for the first time. It is our intention to create a useful reference for plant histology and related methods that will serve as a foundation for plant scholars, researchers, and teachers in the plant sciences. |

| seed anatomy ppt: Chia Ricardo Ayerza, Wayne Coates, 2022-03-15 One of the four main Aztec crops at the time of Columbus’s arrival in the New World, chia is now a forgotten food of the Americas. Chia seed oil offers the highest omega-3 fatty acid content available from plants, but today this species is known only for its use in chia pets. Yet pre-Columbian civilizations used chia as a raw material for medicines and nutritional compounds, while chia flour could be stored for years as a food reserve and was valued as a source of energy on long journeys. In this book, agronomist Ricardo Ayerza and agricultural engineer Wayne Coates trace the long and fascinating history of chia’s use, then reveal the scientific story of the plant and its modern potential. They compare fatty acid profiles of chia with our other major sources—fish oil, flaxseed, and marine algae—and provide evidence that chia is superior in many ways. Here are just some of the benefits that chia provides: - chia has the highest known percentage of alpha-linolenic acid, and the highest combined alpha-linolenic and linoleic fatty acid percentage of all crops - chia has more protein, lipids, energy, and fiber—but fewer carbs—than rice, barley, oats, wheat, or corn—and its protein is gluten-free - chia is an excellent source of calcium, phosphorus, magnesium, potassium, iron, zinc, and copper - chia is low in sodium: salmon has 78 times as much, tuna 237 times as much - chia exhibits no evidence of allergic response, even in individuals with peanut and tree-nut allergies - chia doesn’t give off a “fishy flavor,” unlike some other sources of omega-3 fatty acid The need to balance the essential fatty acid content of the human diet, combined with the need for a safe, renewable, omega-3 fatty acid source, positions chia to become one of the world’s important crops. As this insightful study shows, current nutritional understanding provides an excellent opportunity to reintroduce this important food to the world. |

| seed anatomy ppt: Seed Ecology M.W. Fenner, 2012-12-06 This book is about the regeneration of plants from seed under field conditions. It attempts to give a reasonably balanced overview of the many aspects of this broad topic. The first chapter introduces some general ideas about reproduction in plants. Subsequent chapters deal with the early stages in the life of a plant, from ovule to established seedling, in a more or less chronological order. The final chapter shows how the data on regeneration requirements of different species can be used to explain a number of important characteristics of whole plant communities. The study of the ecological aspects of reproduction by seed touches on a range of issues of current interest in biology. A discussion of seed size and number involves a consideration of the concepts of resource allocation, life cycles and strategies. The in teractions between plants and animals seen in pollination, seed dispersal and predation provide excellent material for the study of coevolution. Investigations on regeneration from seed have greatly our understanding of the causes and maintenance of species added to diversity. The reader will find that virtually all the experiments and field observations described in this book are conceptually very simple. Many of them merely required numerous careful measurements. |
| seed anatomy ppt: Hatchery-based seed production of the Japanese scallop, Mizuhopecten yessoensis Sarkis, A., Lovatelli, A. (ed.), 2022-06-27 This guide is intended as a standalone practical manual for the culture of the Japanese or Yesso scallop, Mizuhopecten yessoensis. It is written for hatchery staff as a reference for daily operating procedures and for developing a site-specific and resource-specific seed production strategy. To that end, the whole production cycle is addressed, from broodstock conditioning to transport of seed to the farm. It is the aquaculturist’s decision as to whether all stages are required to achieve the target production in a given site and hatchery facility. Standard and more recent emerging techniques are included where possible, for the equal benefit of low and high technological operations. The manual starts with a brief overview of the anatomy and morphology of the scallop and describes the main organs of the adult specimen and the stages of its life cycle; the anticipated development time between each stage throughout its culture is added for the aquaculturist’s benefit. This is followed by a chapter on the culture of live microalgae for food; different approaches to culturing large-scale microalgae are given, including traditional batch culture to the more recent newly designed photobioreactors. Protocols are given from stock to intermediate microalgal cultures for the inoculation of large-scale vessels. The integration of probiotic bacteria as an alternative to standard antimicrobial drugs is described in a separate chapter; this is a critical component of this manual as it is a current and important shift in sustaining optimal larval and spat performance. The need for biosecurity in a full cycle hatchery operation is emphasized and conceptually illustrated. The culture protocols for scallops start with the holding and conditioning of broodstock; assessments of the gametogenic stage, the manipulation of holding temperature to maintain and/or enhance gametogenesis and food requirements are all discussed to ensure the supply of broodstock for spawning when needed. Larval culture is one of the longest chapter of this manual and describes rearing in both static and flow-through systems with the expected growth and survival rate for the Japanese scallop. Post-larval culture in the nursery chapter is divided into early post-set up to Day-14, rearing of 1 mm spat and raising seed up to 5 mm or more in a land-based environment. The final chapter discusses different strategies affecting the time and size at which seed are transferred out of the nursery facility to either intermediate outdoor nurseries or to the farm sites. |
| seed anatomy ppt: Plant Evolution Karl J. Niklas, 2016-08-12 Although plants comprise more than 90% of all visible life, and land plants and algae collectively make up the most morphologically, physiologically, and ecologically diverse group of organisms on earth, books on evolution instead tend to focus on animals. This organismal bias has led to an incomplete and often erroneous understanding of evolutionary theory. Because plants grow and reproduce differently than animals, they have evolved differently, and generally accepted evolutionary views—as, for example, the standard models of speciation—often fail to hold when applied to them. Tapping such wide-ranging topics as genetics, gene regulatory networks, phenotype mapping, and multicellularity, as well as paleobotany, Karl J. Niklas’s Plant Evolution offers fresh insight into these differences. Following up on his landmark book The Evolutionary Biology of Plants—in which he drew on cutting-edge computer simulations that used plants as models to illuminate key evolutionary theories—Niklas incorporates data from more than a decade of new research in the flourishing field of molecular biology, conveying not only why the study of evolution is so important, but also why the study of plants is essential to our understanding of evolutionary processes. Niklas shows us that investigating the intricacies of plant development, the diversification of early vascular land plants, and larger patterns in plant evolution is not just a botanical pursuit: it is vital to our comprehension of the history of all life on this green planet. |
