Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Genetics of Quaking Aspen Edmonton, Moss (1960) found that the average date of flowering for quaking aspen has been April 25 for the period 1928-1960, and occurred only after 6 days of air temperatures of 12 C or more. An increasing heat requirement for flowering in more severe cli mates could be an important survival trait, but provenance studies are needed to determine if such is the case.

Download or read book Genetics and Genomics of Populus written by Stefan Jansson and published by Springer. This book was released on 2010-03-02 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetics and Genomics of Populus provides an indepth description of the genetic and genomic tools and approaches for Populus, examines the biology that has been elucidated using genomics, and looks to the future of this unique model plant. This volume is designed to serve both experienced Populus researchers and newcomers to the field. Contributors to the volume are a blend of researchers, some who have spent most of their research career on Populus and others that have moved to Populus from other model systems. Research on Populus forms a useful complement to research on Arabidopsis. In fact, many plant species found in nature are – in terms of the life history and genetics – more similar to Populus than to Arabidopsis. Thus, the genetic and genomic strategies and tools developed by the Populus community, and showcased in this volume, will hopefully provide inspiration for researchers working in other, less well developed, systems.

Book excerpt: Information about the biology, ecology, and management of quaking aspen on the mountains and plateaus of the interior western United States, and to a lesser extent, Canada, is summarized and discussed. The biology of aspen as a tree species, community relationships in the aspen ecosystem, environments, and factors affecting aspen forests are reviewed. The resources available within and from the aspen forest type, and their past and potential uses are examined. Silvicultural methods and other approaches to managing aspen for various resources and uses are presented.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Three studies were conducted to evaluate the fungal degradation properties of young transgenic aspen trees (Populus tremuloides). The first study focused on development of methods of decaying small diameter tree samples. The second and third studies focused on the mass loss differences and cellulose and lignin degradation between trees with different lignin types and contents. In the first study, two methods for rapid laboratory fungal decay tests of very young small diameter (5-15 mm) hybrid poplar (Populus nigra x Populus maximowiczii), yellow poplar (Liliodendron tulipifera), and willow (Salix sp.) trees were examined using the white rot fungi Trametes versicolor and Ceriporiopsis subvermispora. An agar plate method and a modified soil-agar block method were compared using non-standard size stem parts. The agar plate method did not prove to be suitable for testing materials when limited numbers of samples are available because of the extremely high variation of mass loss values. Mass loss using the modified soil-agar block technique was comparable to established methods for small and large blocks using extended colonization periods. In the second study, one-year old quaking aspen (Populus tremuloides) trees including a control wild type aspen and three lines of transgenic trees were analyzed for resistance to lignin selective white rot fungal decay. The transgenics had reduced lignin content through transfer of an antisense -4CL gene, changed syringly/guaiacyl ratio through insertion of a sense CAld5H gene, and modified lignin content and syringyl/guaiacyl through simultaneous insertion of -4CL and CAld5H genes. Mass loss was used to examine differences between genetic lines. The small diameter transgenic trees were decayed using lignin selective white rot fungus Ceriporiopsis subvermispora. A modified soil-agar block method was used with a forty day colonization time. The transgenic lines with higher S/G lignin ratio exhibited a higher mass loss percentage compa.

This book was released on 2011-06-29 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: Millions of trees live and grow all around us, and we all recognize the vital role they play in the world’s ecosystems. Publicity campaigns exhort us to plant yet more. Yet until recently comparatively little was known about the root causes of the physical changes that attend their growth. Since trees typically increase in size by three to four orders of magnitude in their journey to maturity, this gap in our knowledge has been a crucial issue to address. Here at last is a synthesis of the current state of our knowledge about both the causes and consequences of ontogenetic changes in key features of tree structure and function. During their ontogeny, trees undergo numerous changes in their physiological function, the structure and mechanical properties of their wood, and overall architecture and allometry. This book examines the central interplay between these changes and tree size and age. It also explores the impact these changes can have, at the level of the individual tree, on the emerging characteristics of forest ecosystems at various stages of their development. The analysis offers an explanation for the importance of discriminating between the varied physical properties arising from the nexus of size and age, as well as highlighting the implications these ontogenetic changes have for commercial forestry and climate change. This important and timely summation of our knowledge base in this area, written by highly respected researchers, will be of huge interest, not only to researchers, but also to forest managers and silviculturists.

This book was released on 2017 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quaking aspen (Populus tremoloides) is the most widely distributed tree in North America (Lindroth and St Clair 2013), and a keystone species in our western montane forests (Worrall et al. 2015). Aspen has become a model organism for studies of genetics and physiology in woody plants (Bradshaw et al. 2000, Taylor 2002). Aspen is also economically important (Worrall et al. 2015) – wood is harvested for various uses, its scenic beauty helps sustain the tourism economy in many areas, and it has recently been studied as a possible source of biofuel (Sannigrahi et al. 2010).
