Book excerpt: Excerpt from Top and Root Moisture Content of Stored Douglas-Fir Planting Stock Thus, we have evidence that tops of desiccated seedlings contain substantially more water than roots do; that deleterious effects of desiccation probably occur first in roots; and that living roots are not necessary for maintenance of live plant foliage over a substantial period of time. We might, therefore, speculate as to the true cause of some seedling deaths in the late Spring or early summer after planting.

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.
Download or read book Transplant Shock in Stored and Unstored 2 0 Douglas fir Seedlings written by Diane L. Haase and published by . This book was released on 1991 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transplant shock was induced by applying a range of soil water contents to unstored and cold-stored two-yearold (2+0) bareroot Douglas-fir seedlings graded by root volume. Moisture stress had the greatest influence on morphological characteristics commonly associated with transplant shock. Terminal growth, lateral growth, stem diameter growth, and needle length increased dramatically in seedlings from 6% to 24% soil water content. In addition, number of needles per centimeter on the terminal greatly decreased with increasing soil water content. Higher root volume seedlings tended to have slow initial growth under high moisture stress but later showed a significant positive impact on overall growth regardless of soil water content. In every case, seedlings grown in the driest soil had the lowest dry weights and those grown in the most moist soil had the highest weights for all seedling components. Likewise, seedlings with the smallest initial root volumes had the lowest dry weights and the largest root volume seedlings had the highest weights. In addition, macronutrient concentrations and contents of the older foliar tissue was determined. Decreasing soil water content resulted in higher nutrient concentrations of nitrogen, phosphorous and potassium, particularly of nitrogen, in the old foliar tissue. This is primarily due to reduced growth and hence reduced translocation, metabolic activity, and nutrient requirement caused by moisture stress. Seedlings with higher root volumes had higher nutrient concentrations and contents and increased growth. This may be due to increased total root biomass per unit of soil area with increasing seedling root volume resulting in greater nutrient use, supply, uptake, and storage. The results indicate that moisture stress is a primary cause of transplant shock and that seedlings with increasing root volume may be better able to avoid shock following outplanting to a specific site.

This book was released on 2013-04-17 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication comprises the proceedings of the first International Conference devoted to the structural roots of trees and woody plants. 'The Supporting Roots - Structure and Function,' 20-24 July 1998, Bordeaux, France. The meeting was held under the auspices ofIUFRO WPS 2. 01. 13 'Root Physiology and Symbiosis,' and its aim was to bring together scientific researchers, foresters and arboriculturalists, to discuss current problems in structural root research and disseminate knowledge to an audience from a wide disciplinary background. For the first time in an international conference, emphasis was placed on presenting recent reseach in the field of tree anchorage mechanics and root biomechanics. The way in which tree stability can be affected by root system symmetry and architecture was addressed, as well as how movement during wind sway can influence the development and shape of woody roots. The role of different nursery and planting techniques was discussed, in relation to effects on root system form and development. Root response to different environmental stresses, including water, temperature, nutrient and mechanical stress was addressed in detail. The structure and function of woody roots was also considered at different levels, from coarse to fine roots, with several papers discussing the interaction between roots and the rhizosphere. One of the conference highlights was the presentation of new methods in root research, by a series of workshops held at LRBB-INRA, Pierroton, on the northern border of the Gascony forest.

Book excerpt: INSTANT NATIONAL BESTSELLER NEW YORK TIMES BESTSELLER *WINNER of the 2021 Banff Mountain Book Prize in Mountain Environment and Natural History* *WINNER of the National Outdoor Book Award for Natural History Literature* *SHORTLISTED for the 2022 BC and Yukon Hubert Evans Non-Fiction Book Prize* *SHORTLISTED for the 2022 BC and Yukon Bill Duthie Booksellers’ Choice Award* *SHORTLISTED for the 2021 Science Writers and Communicators of Canada Book Award* A world-leading expert shares her amazing story of discovering the communication that exists between trees, and shares her own story of family and grief. Suzanne Simard is a pioneer on the frontier of plant communication and intelligence; she’s been compared to Rachel Carson, hailed as a scientist who conveys complex, technical ideas in a way that is dazzling and profound. Her work has influenced filmmakers (the Tree of Souls in James Cameron’s Avatar), and her TED talks have been viewed by more than 10 million people worldwide. Now, in her first book, Simard brings us into her world, the intimate world of the trees, in which she brilliantly illuminates the fascinating and vital truths—that trees are not simply the source of timber or pulp but are a complicated, interdependent circle of life; that forests are social, cooperative creatures connected through underground networks by which trees communicate their vitality and vulnerabilities with communal lives not that different from our own. Simard describes up close—in revealing and accessible ways—how trees, living side by side for hundreds of years, have evolved; how they perceive one another, learn and adapt their behaviors, recognize neighbors, and remember the past; how they have agency about their future; how they elicit warnings and mount defenses, compete and cooperate with one another with sophistication: characteristics previously ascribed to human intelligence, traits that are the essence of civil societies. And, at the center of it all, the Mother Trees: the mysterious, powerful forces that connect and sustain the others that surround them.Simard, born and raised in the rain forests of British Columbia, spent her days as a child cataloging the trees from the forest; she came to love and respect them and embarked on a journey of discovery and struggle. Her powerful story is one of love and loss, of observation and change, of risk and reward. And it is a testament to how deeply human scientific inquiry exists beyond data and technology: it’s about understanding who we are and our place in the world. In her book, as in her groundbreaking research, Simard proves the true connectedness of the Mother Tree to the forest, nurturing it in the profound ways that families and humansocieties nurture one another, and how these inseparable bonds enable all our survival.
Download or read book Non wood Forest Products from Conifers written by William M. Ciesla and published by Fao. This book was released on 1998 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this paper is to provide a global review of the non-wood uses of conifers. For the purposes of this paper, conifers are defined as trees and shrubs of the botanical orders Coniferales, Taxales and Ginkgoales (Rushforth 1987). Although some services are briefly mentioned, the focus of this paper is on products which conifers provide species, which are important sources of non-wood forest products, and places where these products are harvested. With the exception of essential oils, which can be obtained from several parts of the tree, the products described are organized by the part of the tree from which they are obtained (e.g. foliage, bark and roots, resin, seeds and cones). Where possible, data on levels of production and international trade are presented. Problems associated with the sustainable management of these products and compatibility or conflicts with other land uses are also presented. Both contemporary and historical or traditional uses of non-wood products from conifers are discussed.
