        Seed Fate

        Predation, Dispersal and Seedling Establishment

        by Edited by Pierre M Forget, Joanna E Lambert, Philip E Hulme, Stephen B Vander Wall

        This book presents current knowledge of seed fate in both natural and human-disturbed landscapes, from various regions of the world. Habitats considered range from mountain and arid deserts in the temperate zone, to savanna and lowland rainforests in tropical regions of the world. Particular attention is paid to plant diversity conservation when seed removal is affected by factors such as hunting, habitat fragmentation or intensive logging. Contributors include leading scientists involved in research on seed ecology and on animal-plant relationships from the perspective of both primary and secondary seed dispersal, and predation.

        African Seed Enterprises

        Sowing the Seeds of Food Security

        by Edited by Paul Van Mele, J W Bentley, Robert G Guéi

        In most developing countries, good quality seed is hard to obtain and farmers struggle to save seed from one year to the next. Instead, they increasingly turn to public or private enterprises that multiply, store and distribute seed. African Seed Enterprises takes a people-centred look at the companies, public agencies and family farms that are taking on this role and making a difference to food security across Africa. Case studies are arranged by country, and each chapter includes a profile of the agricultural and policy environment that surrounds these enterprises and affects their development. Each case is unique and presents its own set of lessons, and as a whole, this wide range of experiences is a rich source of data and ideas for future enterprise, offering valuable insights for policy makers, academics and non-governmental organizations throughout the world.

        Forage Seed Production, Volume 1

        Temperate Species

        by Edited by Daphne T Fairey, John G Hampton

        The grasses and legumes grown in pastures and rangelands form the basis of the worldwide animal production industry. Some species also have a significant role in the sport and leisure industry, for playing surfaces such as golf courses and football fields. It is therefore vitally important to ensure that seed supplies of appropriate species are available for use on a commercial scale. This book is published in association with the International Herbage Seed Production Research Group. It brings together leading researchers and along with its companion volume Forage Seed Production Volume 2: Tropical and Subtropical Species (to be published in late 1998), provides the definitive resource for all those concerned with breeding and profitable seed production for grasses and legumes used within grazing systems or recreation and amenity provision. The book is in two parts. Part 1 covers all aspects relevant to seed production, including improving seed yield and quality, crop management, harvesting, processing and the international seed trade. Part 2 consists of eleven case studies from eight countries covering three continents. This book and its companion should be read by all seed scientists involved in the breeding and commercial production of grass and legume seed. They also represent a valuable asset for all commercial seed suppliers. Additionally, the information presented within the book is important for all students and lecturers within departments of agriculture and plant breeding.

        Seed Biology and Yield of Grain Crops

        by Dennis B Egli

        This new edition of an established title examines the determination of grain crop yield from a unique perspective, by concentrating on the influence of the seed itself. As the food supply for an expanding world population is based on grain crops harvested for their seeds, understanding the process of seed growth and its regulation is crucial to our efforts to increase production and meet the needs of that population. Yield of grain crops is determined by their assimilatory processes such as photosynthesis and the biosynthetic processes in the seed, which are partly regulated within the seed itself. Providing a timely update in this field and highlighting the impact of the seed on grain crop yields, this book: · Describes all aspects of seed growth and development, including environmental and genetic effects on growth rate and length of the filling period. · Discusses the role of the seed in determining the two main yield components: individual seed weight and number of seeds per unit area. · Uses the concepts and models that have been developed to understand crop management and yield improvement. Substantially updated with new research and further developments of the practical applications of the concepts explored, this book is essential reading for those concerned with seed science and crop yield, including agronomists, crop physiologists, plant breeders, and extension workers. It is also a valuable source of information for lecturers and graduate students of agronomy and plant physiology. ; This is a new edition of an established title examines the determination of grain crop yield from a unique perspective, by concentrating on the influence of the seed itself. ; Chapter 1: IntroductionChapter 2: Seed Growth and DevelopmentChapter 3: Seed Growth Rate and Seed-Fill Duration: Variation and Regulation.Chapter 4: Yield Components-Regulation by the Seed Chapter 5: The Seed, Crop Management, and YieldChapter 6: The Way Forward

        Seed Biology and the Yield of Grain Crops

        by Dennis B Egli

        The food supply to an expanding world population is based on grain crops, i.e. crops harvested for their seeds. Therefore, understanding the process of seed growth and its regulation is crucial in our efforts to increase production, in order to meet the needs of that population. Yield is determined by the ability of crop plants to use their assimilatory processes such as photosynthesis and also the biosynthetic processes in the seed, which are partly regulated within the seed itself. This book examines the determination of grain crop yield from a new and unique perspective, by concentrating on the influence of the seed. All aspects of seed growth and development are described, including environmental and genetic effects on growth rate and length of filling period. The effect of the seed on the two main yield components, individual seed weight and number of seeds per unit area, is then discussed. Finally, the concepts and models developed are evaluated in terms of crop management. The book is essential reading for those concerned with seed science and crop yield, including agronomists, crop physiologists, plant breeders, and extension workers. It will also be a valuable source of information for lecturers and graduate students of agronomy and plant physiology.

        Seed Dispersal and Frugivory

        Ecology, Evolution and Conservation

        by Edited by Douglas J Levey, Wesley R Silva, Mauro Galetti

        Until recently, the production of fruits by plants, their consumption by animals (frugivory) and the relevance of these to seed dispersal have attracted less attention than topics such as pollination biology. However, since the 1970s they have started to gain more prominence and now give rise to more research funding, seminal papers and international symposiums. This book contains chapters adapted from the Third International Symposium-Workshop on Frugivores and Seed Dispersal held in August 2000 in Rio Quente, Brazil.

        Gac Fruit: Advances in Cultivation, Utilisation, Health Benefits and Processing Technologies

        by Minh Nguyen, Tuyen Chan Kha

        Gac fruit, Momordica cochinchinensis Spreng, is rich in nutrients such as carotenoids (particularly beta-carotene and lycopene), fatty acids, vitamin E, polyphenol compounds and flavonoids. This book provides the latest research on this fruit, from cultivation through to processing technologies for health products. It addresses several techniques on propagation and cultivation in order to increase the production and quality of Gac fruit, including traditionally used parts of the fruit (aril) and those whose value has not yet been maximized (peel, pulp and seed). This plant has the potential to be a high value crop, particularly as parts of the fruit can be processed into nutrient supplements and/or natural colorants. It has an exceptional potential in the world carotenoids market of about US$ 1.4 billion (2017), which will be growing steadily, up to US$ 6.9 billion by 2026. As such, this book contains special emphasis on: · Improving production of Gac fruit · Novel extraction of Gac oil rich in beta-carotene and lycopene from aril and peel. · Encapsulation of Gac oil rich in beta-carotene and lycopene. Practical applied technologies such as microwave drying, heat pump drying, freeze drying, ultrasound assisted extraction, supercritical CO2 extraction, encapsulation techniquesare all presented. This is an essential reference text for academics, researchers and graduate students in cultivation, food processing, science and nutrition. Product developers in health food areas in the food industry will also find it valuable.

        by Jorge Esquinca, Chiara Carrer

        A girl and her mother, three crows, spikes on a field, and clouds draw the first scene. But the girl, like all children, expect her great adventure of being lost. The mistery kidnaps her. It leads her to an underground dream where the dream is reality and darkness is clear as a diamond light. Oneiric, musical story, opened to “what is heard inside”, this book invites us to discover that beyond the veil that is spread between the world and the things, “each sleeping seed, each root, each stem, every flower that rises,” and us, entirely.
