Available in PDF, EPUB and Kindle. Book excerpt: S2Ever since the quality-index (Q.I.) concept was introduced by A.M. Herrick in 1946, its importance as a measure of timber value has grown: and it has been used, not only in other research efforts, but also as a tool to be used by foresters and timber operators (Herrick 1946). We have recently employed the Q.I. concept in our rate-of-value-increase studies on nine tree species in the Northeast and recognized that, as a byproduct of this study, the log-quality indexes would be useful to timber operators. This paper briefly reviews the quality-index concept, presents log-quality index tables for a selected group of eastern hardwood tree species, and explains how timber operators can use Q.I. for evaluating the lumber that can be sawed from logs and trees. The Q.I. tables are based on two different lumber price reporting services and cover different geographic regions. Those species that occur in more than one region have a different Q.I. in each region. S3.

This book was released on 1970 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: S2Pills of paraformaldehyde (trioxymethylene) are commonly used in tapholes in sugar maple trees (Acer saccharum Marsh.) to increase the yield of sap collected for making syrup and sugar (2, 4, 5, 8). The explanation offered for this increase in sap yield is that microorganisms in the tapholes (7) cause premature decline and stoppage of the sap flow (1, 6), but that paraformaldehyde increases sap yield by inhibiting their growth (2). But what happens to the tree? To determine the effects of paraformaldehyde on the tissues surrounding tapholes, and on the microorganisms in those tissues, sugar maple trees were dissected and studied. This paper is a report on that study.S3.

Download or read book Balsam Fir written by E. V. Bakuzis and published by U of Minnesota Press. This book was released on 1965-07-30 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: Balsam Fir was first published in 1965. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions. Professors Bakuzis and Hansen, with the assistance of a number of co-authors of individual chapters, present an exhaustive survey of the literature on the balsam fir, providing a coherent picture of the species and its place in nature and forestry practice. The balsam fir is used extensively in the pulp and paper industry, and it is known to millions as a traditional Christmas tree. In North America it is a major tree species in Canada, in the northeastern United States, and in the Great Lakes region. In the search of the literature, over 2000 sources were consulted and considerably more than half of them are cited in the book. The references, organized in an ecological framework, cover the period from the seventeenth century to the present. The authors have reviewed and integrated these data in a unified, but multipurposed, book. In the integration of the source material the authors also made contributions of their own. The book contains the following chapters: Botanical Foundations, Geography and Synecology, Ecological Factors, Microbiology, Entomology, Reproduction, Stand Development, Growth and Yield, and Utilization. Appendixes list fungi and myxomycetes and insects associated with balsam fir. There are 30 illustrations, including a frontispiece drawing by the noted nature artist Francis Lee Jaques. The book will appeal to a wide range of readers specifically concerned with forestry, including research workers, educators, entomologists, pathologists, and managing foresters, as well as conservationists and wildlife biologist in general.
