Available in PDF, EPUB and Kindle. Book excerpt: ‘This plant is the only one which is in a position to store light ether; this will be indispensable for people in future.’ – Rudolf Steiner Koberwitz, Whitsun 1924: Rudolf Steiner had just completed his momentous lecture course on biodynamic agriculture and was waiting for a car to take him to the station. Suddenly he was approached by two of his pupils with an urgent question: Would his new indications for treating soil and vegetables be sufficient to provide, ‘...nutrition appropriate to our times and in accordance with the spirit?’ Steiner’s frank response was somewhat surprising: ‘It will not be sufficient even in the most favourable circumstances. What should be done is to cultivate the Dioscorea batatas in Europe so that it can take over from the potato as the staple diet.’ In the many decades since that conversation, various attempts have been made to cultivate Dioscorea batatas – the ‘light root’ – in Europe, initially by Steiner’s close colleague Guenther Wachsmuth. More recently, biodynamic farmer Ralf Roessner began to research the plant and its background, but soon discovered problems with the specimens available in Europe. Unsatisfied with the standard of the plants, in 2002 he travelled to the original growing areas of Dioscorea batatas in China, where he was able to form a comprehensive picture of the best planting methods and conditions. ‘The nodules which I found and brought back with me’, he writes, ‘showed similar light ether characteristics to the original plants of Wachsmuth’s’. Having successfully cultivated and marketed this light root, Roessner presents some carefully assembled introductory materials based on his experiences and those of a colleague. This small book, illustrated with colour images, is intended for people who wish to discover more about the plant’s being and spiritual mission as a ‘helper of progress’. Roessner explains how the light root stores ‘light ether’ in a unique manner, making it not only a valuable food, but also a ‘carrier of the spirit’. This light root could even ‘...decisively influence the development of humanity and the earth’. Aside from studying esoteric aspects, he gives answers to frequently-asked practical questions about the plant and its cultivation.

Book Synopsis Biology of Adventitious Root Formation by : Tim D. Davis
Download or read book Biology of Adventitious Root Formation written by Tim D. Davis and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Charles E. Hess Department of Environmental Horticulture University of California Davis, CA 95616 Research in the biology of adventitious root formation has a special place in science. It provides an excellent forum in which to pursue fundamental research on the regulation of plant growth and development. At the same time the results of the research have been quickly applied by commercial plant propagators, agronomists, foresters and horticulturists (see the chapter by Kovar and Kuchenbuch, by Ritchie, and by Davies and coworkers in this volume). In an era when there is great interest in speeding technology transfer, the experiences gained in research in adventitious root formation may provide useful examples for other areas of science. Interaction between the fundamental and the applied have been and continue to be facilitated by the establishment, in 1951, of the Plant Propagators' Society, which has evolved into the International Plant Propagators' Society, with active programs in six regions around the world. It is a unique organization which brings together researchers in universities, botanical gardens and arboreta, and commercial plant propagators. In this synergistic environment new knowledge is rapidly transferred and new ideas for fundamental research evolve from the presentations and discussions by experienced plant propagators. In the past 50 years, based on research related to the biology of adventitious root formation, advances in plant propagation have been made on two major fronts.

End-of-chapter questions challenge students to think critically and creatively while incorporating science process skills and biological principles.
Book Synopsis SEBS 30 Root Development and Function by : P. J. Gregory
Download or read book SEBS 30 Root Development and Function written by P. J. Gregory and published by CUP Archive. This book was released on 1987-04-24 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: First published in 1987 this book looks at root development and functions. Besides affecting the development of roots directly, the physical environment also influences the organisms associated with roots and thus affects their function. The papers presented in this volume pay equal attention to root development and root function in relation to the whole range of environmental factors including temperature, light, water, aeration, gravity and the mechanical strength of the soil. Consideration is also given to the effects of some of these factors on mycorrhizae and nitrogen-fixing bacteria. The final chapter reviews some of the main themes raised in the volume and indicates the way that research at the cellular and tissue levels may progress in the future.

Download or read book Root Ecology written by Hans de Kroon and published by Springer Science & Business Media. This book was released on 2003-05-21 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the course of evolution, a great variety of root systems have learned to overcome the many physical, biochemical and biological problems brought about by soil. This development has made them a fascinating object of scientific study. This volume gives an overview of how roots have adapted to the soil environment and which roles they play in the soil ecosystem. The text describes the form and function of roots, their temporal and spatial distribution, and their turnover rate in various ecosystems. Subsequently, a physiological background is provided for basic functions, such as carbon acquisition, water and solute movement, and for their responses to three major abiotic stresses, i.e. hard soil structure, drought and flooding. The volume concludes with the interactions of roots with other organisms of the complex soil ecosystem, including symbiosis, competition, and the function of roots as a food source.

This book was released on 2012-12-06 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the majority of the presentations of the Second International Symposium on the Biology of Root Formation and Development that was hcld in Jerusa lem, Israel, June 23---28, 1996. Following the First Symposium on the Biology of Adventi tious Root Formation, held in Dallas. USA, 1993, we perceived the need to include all kinds of roots, not only the shoot-borne ones. The endogenous signals that control root formation. and the subsequent growth and development processes, are very much alike, re gardless of the sites and sources of origin of the roots. Therefore, we included in the Sec ond Symposium contributions on both shoot-borne (i.e., adventitious) roots and root-borne (i.e., lateral) roots. Plant roots have remained an exciting and an intriguing field of sciencc. During thc years that followed the first symposium, an exceptional proliferation of interest in root biology has developed, associated with the intensive research activity in this field and the contemporary developments in the understanding of root function and development. New methods have been applied, and old ideas and interprctations werc rccxamined. Alto gether, it became necessary to update our viewpoints and to expand them.
Download or read book Root Biology written by Takuji Ohyama and published by BoD – Books on Demand. This book was released on 2019-11-20 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides up-to-date knowledge of root biology. Most plants have roots, which anchor the plant in the soil and physically support the above-ground parts of the plant. In addition, roots absorb water and nutrients from the soil and transport this to the shoot. Roots grow by cell proliferation in the meristem in the root tip. The cells differentiate into the epidermis, cortex, and stele. Water and nutrients are absorbed through the cell membrane of the epidermis and are transported to the above-ground parts via xylem vessels. The root growth and functions are affected by various abiotic and biotic conditions, such as levels of water, salt, acid stresses, and presence of soil diseases. However, some beneficial microorganisms such as rhizobia and mycorrhizal fungi help plant growth.
