Download or read book The Biology and Utilization of Grasses written by V Younger and published by Elsevier. This book was released on 2012-12-02 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Biology and Utilization of Grasses reviews current knowledge about grass biology, and it highlights the important role of grasses in human existence. It discusses many fundamental aspects of grass biology, including evolution and genetics, morphology, physiology, and ecology, with emphasis on the relationship of these basic concepts to the use of grasses for forage, turf, and rangelands. Comprised of 28 chapters, this volume begins with an overview of the evolution and genetics of the grass family, followed by a discussion on practical grass-breeding problems. The reader is also introduced to vegetative growth and development of seedlings and mature plants; the ecological aspects of grasses; soils and mineral nutrition in relation to grass growth; the effects of defoliation (moving or grazing); carbohydrate reserves; physiology of flowering; and grass seed production and culture treatments. Other chapters consider the role of polyploidy in the evolution and distribution of grasses; selection and breeding of grasses for forage and other uses; seedling vigor and seedling establishment; environmental modification for seedling establishment; the microclimate of grass communities; effects on turf grass of cultural practices in relation to microclimate; and competition within the grass community. This book will be of benefit to plant breeders, ecologists, botanists, and biologists.
Download or read book Biogeography and Ecology of the Pityusic Islands written by K. Kuhbièr and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 701 pages. Available in PDF, EPUB and Kindle. Book excerpt: A large part of this book is dedicated to the geology of the Pityusic Archipelago, followed by contributions on climate and geography. Funguses, mosses and leeks are the subjects of taxonomical botany, and a further paper deals with the vegetation of the islands. Another large part of this book is concerned with zoology: faunal lists on fleas, bees, wasps, ants, butterflies, beetles, snails, amphibians and reptiles, birds and mammals, the latter with their epi- and endofaunas as well as their subfossil remains are presented in 13 different papers. Three of them deal with the special problems of isolation and evolution of new races on rocks and small islets: tenebrionid beetles, lizards and terrestrial snails. Man, as an important factor in the Pityusic Islands, is dealt with in six contributions: prehistory, which means pre-Phoenician and which is treated for the first time, folk architecture, the 'endemic' dialect of the Catalonian language, exploitation of some natural resources and finally the problems of inbreeding and related matters on Formentera. The book closes with an outlook on the present state of the Pityusic nature and tries to show ways of conserving all important parts of the archipelago, so that 'our' two islands may preserve some of their typical vegetation, plants and animals and, thus, of their character.

Download or read book Vistas in Botany written by W. B. Turrill and published by Elsevier. This book was released on 2013-10-22 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vistas in Botany, Volume 4: Recent Researchers in Plant Taxonomy covers some of the more important general aspects of plant taxonomy. This volume is composed of seven chapters that link the practice and theory of taxonomy to plant geography, ecology, pollen anatomy, embryology, genetics, and cytology. The opening chapter outlines the views on plant taxonomy classification, the relevance of these views to biological classification, and some of the problems of classification in the non-taxonomic fields of ecology, soil science, and librarianship. The succeeding chapter presents the classification of the spores in higher plants, the cormophytes. This topic is followed by discussions on the embryological characters of taxonomic significance and the interrelations of plant taxonomy, phytogeography, and plant ecology. The final chapters consider the taxonomic preparation of flora and plant fossils. This book will prove useful to taxonomists, botanists, ecologists, and scientists and researchers in the allied fields of botany.
Download or read book Somatic Embryogenesis and Synthetic Seed II written by Y. P. S. Bajaj and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: While working in the laboratory of Professor Dr. Jacob Reinert at the Freie Universitat Berlin (1974-1976), I had the opportunity to become deeply involved in studying the intricacies of the fascinating phenomenon of somatic embryogenesis in plant cells and protoplasts. In numerous stimu lating discussions with Professor Reinert on this subject, I was fully convinced that somatic embryogenesis would become one of the most important areas of study, not only regarding basic and fundamental aspects, but also for its application in crop improvement. During the last decade, we have witnessed tremendous interest and achievements in the use of somatic embryos for the production of synthetic seeds, for micro prop a gation, genetic transformation, cryopreservation, and conservation of germplasm. The en masse production of somatic embryos in the bioreactors has facilitated some of these studies. Somatic embryos have now been induced in more than 300 plant species belonging to a wide range offamilies. It was therefore felt that a compilation ofliterature/state of the art on this subject was necessary. Thus, two volumes on Somatic Embryo genesis and Synthetic Seed have been compiled, which contain 65 chapters contributed by International experts. Somatic Embryogenesis and Synthetic Seed I comprises 31 chapters, arranged in 3 sections: Section I Commitment of the cell to somatic embryogenesis; early events; anatomy; molecular basis; gene expression; role of polyamines; machine vision analysis of somatic embryos. Section II Applications of somatic embryos; technology of synthetic seed; fluid drilling; micropropagation; genetic transfor mation through somatic embryos; cryopreservation.
Download or read book Breeding strategies for sustainable forage and turf grass improvement written by Susanne Barth and published by Springer Science & Business Media. This book was released on 2012-07-25 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the 4th – 8th of September 2011, the Eucarpia Fodder Crops and Amenity Grasses Section, held its 29th Meeting in the surroundings of Dublin Castle in Ireland. The theme of the meeting was ‘Breeding strategies for sustainable forage and turf grass improvement’. Grasslands cover a significant proportion of the land mass of the world, and play a pivotal role in global food production. At the same time we are faced with several challenges that affect the way in which we think about this valuable set of resources. The population of the world is expected to exceed 9 billion by 2050, and increase of about one third relative to today’s levels. This population increase will be focused in urban areas, and in what are currently viewed as “developing” countries, meaning that the buying power of this increased population will be greater – shifting the balance of demand from staple crops to high value items such as meat and dairy products. Overall that the world will have to approximately double agricultural output across all categories of food to meet the demands of this larger, urbanised population. This is occurring against a backdrop of equally large challenges in terms of global climate change. Agriculture is already a significant contributor to e.g. greenhouse gas emissions, deforestation and soil erosion. The situation is made more complex by an increased emphasis on biofuels as a solution for our imminent oil shortage, resulting in increased competition between land utilised for food and fuel. In short, agriculture must continue to feed the world, whilst not contributing to damaging it further. It must be sustainable. Plant breeding plays a significant but frequently understated role in meeting the challenges presented by this complex and changing scenario. However, plant breeding and improvement is itself undergoing radical change driven by technology. This book explores how forage and turf breeding is changing and adapting to meet these challenges using the technological advances being experienced in plant breeding as a whole.
