Growth and Development of Trees, Volume II: Cambial growth, Root Growth, and Reproductive Growth describes the important features of growth and development of trees and other woody plants during their life cycles. This nine-chapter book highlights the significant changes that take place in vegetative and reproductive growth as woody plants progress from juvenility to adulthood and, finally, to a senescent state. The first four chapters cover the growth of tree cambium, which is a layer of delicate meristematic tissue between the inner bark or phloem and the wood or xylem. These chapters examine the variation, control, and measurement of cambial growth. The next two chapters look into the growth mechanism of specialized and modified root systems, such as aerial, grafted, knee, and nodulated roots, root buttresses, mycorrhiza, and pneumatophores. These chapters also discuss the distribution and growth characteristics of roots of woody plants. Other chapters explore the significant changes and features during flowering and fruit, cone, and seed development. The last chapter considers some aspects of internal and external control of reproductive growth at critical stages of development. Some practical methods for stimulating fruit and seed production by trees are also provided. This book will be of great value to arborists, foresters, horticulturists, plant ecologists, plant physiologists, plant anatomists, tree breeders and geneticists, plant pathologists, entomologists, soil scientists, meteorologists, and landscape architects. It is also intended for upper level undergraduate and graduate students.

Growth and Development of Trees, Volume I: Seed Germination, Ontogeny, and Shoot Growth is a part of a two-volume treatise, which characterizes important features of growth and development of trees and other woody plants during their life cycles. Organized into eight chapters, this book describes the important events in growth of the perennial woody plant. This volume highlights the significant changes that take place in vegetative and reproductive growth as woody plants progress from juvenility to adulthood and, finally, to a senescent state. This book also describes the effects of external and internal controls of vegetative and reproductive growth. Considerable attention is given to important spatial and temporal variations in growth. This book will be useful to academicians as well as to those involved in the practice of growing trees and other woody plants for fruit crops or wood, as well as for esthetic reasons.

V.1 - Seed germination, ontogeny and shoot growth; v. 2 - cambrial growth root growth and reproductive growth.

Discusses the evolution of forestry and agroforestry and presents the core literature in these fields, covering both traditional and emerging areas. Topics include changes in forest science in the 20th century, the development of agroforestry literature, the role of professional societies and the US

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.

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.
