Download or read book Handbook of Flowering written by Abraham H. Halevy and published by CRC Press. This book was released on 2018-02-01 with total page 745 pages. Available in PDF, EPUB and Kindle. Book excerpt: These volumes are an exhaustive source of information on the control and regulation of flowering. They present data on the factors controlling flower induction and how they may be affected by climate and chemical treatments. For each plant, specific information is provided on all aspects of flower development, including sex expression, requirements for flowering initiation and development, photoperiod, light density, vernalization, and other temperature effects and interactions. Individual species are described from the standpoint of juvenility and maturation, morphology, induction and morphogenesis to anthesis. All information is presented alphabetically for easy reference

Download or read book Plantation silviculture written by K.R. Shepherd and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plantations of a wide range of tree species have assumed an important place in our world, providing wood for industry, fuelwood and animal fodder, protection from adverse environments and for the soil, as well as amenity and aesthetically pleasing landscapes. silvicultural knowledge of this particular branch of forestry first developed in Europe more than two centuries ago but in many parts of the world is still in a process of rapid evolution as more and more plantations are established to meet specific needs. The first exotic tree species to be established in plantations in my own country were planted more than a century ago and, likewise, New Zealand has a long history of planting. Both countries have developed a vigorous and innovative approach to plantation practice, soundly based initially on European experience but gradually modified to meet the challenges of new environments, new markets, and changed economic circumstances. This book on plantation silviculture was begun some years ago when the lack of a suitable undergraduate text for teaching purposes became apparent. The present text is aimed essentially at this audience. Although I have drawn heavily on the experience of Australia and New Zealand, the principles outlined are applicable anywhere in the world where plantations are being grown and tended, from the United States and Scandinavia to India, South Africa or Brazil. The text should also serve as a useful reference to advanced students and practicing foresters, with the reference list providing an introduction to the literature on this subject.

This book was released on 2012-12-06 with total page 909 pages. Available in PDF, EPUB and Kindle. Book excerpt: R. P. PHARIS and D. M. REID The idea of a separate Encydopedia volume dealing with the "interrelations of plant hormones with factors in the environment of the plant, and its organs and tissues" originated with N. P. KEFFORD, and we are most appreciative of the help and advice provided by Prof. KEFFORD in the formative stages of this volume. We have thus interpreted "environment" very broadly to indude not only factors external to the plant, e. g. , gravity, light, temperature, wind, mechanieal wounding, water, organism s (induding pollen), and magnetic and electric stimuli, but internaI factors as well (e. g. , nutrients, both inorganic and photoassimilate, direction, and time). In our definition of "hormonaI effect", or "hormonaI involvement", we have asked our authors to take a broad ap proach, and to examine not only phenomena that are mediated by the known plant hormones, but to discuss as well a wide variety of processes and events where hormonal involvement is implied through more indirect analyses and observations. The volume begins with environmental factors internaI to the plant; R. J. WEAVER and J. O. JOHNSON thus examine "hormones and nutrients", their inter relationship in movement, accumulation, and diversion. As one studies a plant during its rapid growth phase, and later as maturation and aging proceed, it becomes apparent that time is an environmental cue of great significance, one which may exert a major influence via hormonal messages.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this two-volume work is to make available both to the investigator and user, on a crop by crop basis, the latest information on the use of chemicals to regulate plant growth and development. Emphasis is given to the major crops and to those which the most success has been achieved.

Download or read book Hormonal Control of Tree Growth written by S.V. Kossuth and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the third annual compendium of a Technical Session of the Physiology Working Group of the Society of American Foresters held at the National Convention. Specialists in a dedicated area of tree physiology were invited to prepare chapter contributions synthesizing the status of knowledge in their area of expertise. Plant growth regulators (PGRs) was selected as the topic for in-depth examination at the 1986 Technical Session because a knowledge of how these "secondary messengers" regulate tree morphogenesis is vital to applications of biocontrol and biotechnology. Plant growth regulators have been the subject of numerous reviews in recent years. However, few have dealt specifically with woody perennials, and they are generally confined to single processes and/or organs. This volume attempts to provide a more comprehensive treatise of PGRs as they influence various ontogenetic events in forest trees. Reproductive physiology, both sexual and asexual, is emphasized because of its relevance to current efforts directed at increasing efficiency in the breeding and production of genetically improved trees for reforestation. The chapters on vegetative growth will be of interest to silviculturists and urban foresters as they consider cultural treatments in the management of forests and individual trees for specific products and purposes. This book should serve as a valuable text and source of reference for students, researchers and other professionals interested in gaining a better understanding of PGRs. The reader, however, who expects definitive answers to how PGRs function or can be used to control specific processes is likely to be disappointed.

Marie : Ontario Ministry of Natural Resources. This book was released on 1996 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Describes a study conducted to determine whether pollen-cone production of black spruce can be promoted by growing grafts in a heated greenhouse and in an outdoor holding area, and spraying these grafts with different concentrations of naphthaleneacetic acid (NAA) during the periods of lateral shoot production. Begins with a review of research on the effects of NAA on pollen-cone production, then describes experimental materials and methods used. Results presented include effect of NAA spray concentrations on spruce mortality, effect of NAA spraying on pollen cone production, effectiveness of heat treatment combined with NAA spraying, and differences between indoor and outdoor treatments.
