Book References no  25162 28495   ABD ZVE

Download or read book References no 25162 28495 ABD ZVE written by Zdenek Sesták and published by Springer Science & Business Media. This book was released on 2013-12-18 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: The bib I iography includes papers in alI fields of photosynthesis research - from stu dies of model biochemical and biophysical systems of the photosynthesis mechanism to primary production studied by the so-cal led growth analysis. In addition to papers devoted entirely to photosynthesis, papers on other topics are included if they con tain data on photosynthetic activity, photorespiration, chloroplast structure, chlo rophyl I and carotenoid synthesis and destruction; etc., or if they contain valuable methodo I og i ca I information (measurement of se I ected env i ronmenta I ·factors, I eat area, etc.). In many branches it has been very difficult to define the I imits of interest for photosynthesis researchers. This problem has arisen e. g. in topics dealing with the transport of gases, where- in addition to the papers on C0 transfer- some pa 2 pers on water vapour transfer are included, these being of general application. On the other hand, many papers dealing with the anatomy and physiology of stomata have been omitted, if the aspect of carbon dioxide or water vapour exchange has not been discussed. This volume contains references to papers pub I ished in the year 1976, and, similarly to Vol. 6, also addenda including references pub I ished in the preceding period (i. e. 1966- 1975). The numbers of these additional references are label led with an asterisk in the I ist of references.

Book Cell and Tissue Culture in Forestry

Download or read book Cell and Tissue Culture in Forestry written by J.M. Bonga and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the first edition of our book "Tissue Culture in Fores try" in 1982 we have witnessed remarkable advances in cell and tissue culture technologies with woody perennials. In addition to forest biologists in government, industry, and universities, we now have molecular biologists, genetic engineers, and biochemists using cell and tissue cultures of woody species routinely. There fore, the time has come for an update of the earlier edition. In our present effort to cover new developments we have expanded to three volumes: 1. General principles and Biotechnology 2. Specific Principles and Methods: Growth and Development 3. Case Histories: Gymnosperms, Angiosperms and Palms The scientific barriers to progress in tree improvement are not so much lack of foreign gene expression in plants but our current inabili ty to regenerate plants in true-to-type fashion on a mas sive and economic scale. To achieve this in the form of an appro pr iate biotechnology, cell and tissue culture will increasing ly require a better understanding of basic principles in chemistry and physics that determine structural and functional relationships among molecules and macromolecules (proteins, RNA, DNA) within cells and tissues. These principles and their relationship with the culture medium and its physical environment, principles of clonal propagation, and genetic variation and ultrastructure are discussed in volume one.

Available in PDF, EPUB and Kindle. Book excerpt: Eucalypts are being brought into cultivation as wood-producing crops throughout the warmer parts of the world. This practical book shows how to breed improved varieties, and how to select appropriate sites, with an emphasis on making the best use of the genetic resources of eucalypts. It shows how well-planned and recurrent selection and mating can ensure long-term genetic gain after suitable base populations have been assembled, affecting both the quality and quantity of the wood produced.

Download or read book Plant Embryo Culture written by Trevor A. Thorpe and published by Humana Press. This book was released on 2011-01-07 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: A great fascination for biologists, the study of embryo development provides indispensable information concerning the origins of the various forms and structures that make up an organism, and our ever-increasing knowledge gained through the study of plant embryology promises to lead to the development of numerous useful applications. In Plant Embryo Culture: Methods and Protocols, expert researchers from the field provide a ready source of information for culturing zygotic embryos for different types of studies, both theoretical and practical. The book’s main sections examine a wide range of related topics, including the culture of zygotic embryos for developmental studies, the application of embryo culture techniques focusing on embryo rescue methods, cryopreservation of zygotic embryos, the use of zygotic embryos as explants for somatic embryogenesis and organogenesis, as well as transformation protocols using zygotic embryos as starting material. Written in the highly successful Methods in Molecular BiologyTM series format, the detailed chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and vital notes on troubleshooting and avoiding known pitfalls. Authoritative and convenient, Plant Embryo Culture: Methods and Protocols serves as a key reference that can be used by scientists of all backgrounds to help develop their own customized methods for many different species and for a variety of purposes.

Book Heterosis

    Book Details:
  • Author : R. Frankel
  • Publisher : Springer Science & Business Media
  • Release : 2013-06-29
  • ISBN : 364281977X
  • Pages : 301 pages

Download or read book Heterosis written by R. Frankel and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: When trying to solicit authors for this book it became apparent that the causal factors for heterosis at the physiological and biochemical level are today almost as obscure as they were 30 years ago. Though biometrical-genetical analyses point to dispersion of complementary genes - not overdominance - as the major cause of the phenomenon, plant breeders' experience still suggests a cautious, pragmatic approach to the dominance-overdominance controversy in breeding hybrid cultivars. Thus we are faced with a striking discordance between our limited comprehension of the causal factors and mechanism of heter osis on the one hand, and the extensive agricultural practice of utiliza tion of hybrid vigor on the other. Such utilization is the result of the economic value of hybrid combinations displaying superior yields and qualities as well as stability of performance, of benefits derived in breeding programs, and of the enhanced varietal protection of proprietary rights. No comprehensive and critical analysis of the phenomenon of heterosis in economic plants has been published for the last three decades since the now classical book Heterosis, edited by J . W. Gowen (Iowa State College Press, Ames, Iowa, 1952). The present book attempts to fill the gap and to assess the status of our present knowl edge of the concept, the basis, the extent, and the application of heterosis in economic plants.
