Download or read book The Course of Growth Response in Released White Spruce written by Robert M. Frank and published by . This book was released on 1973 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Weekly bole measurements at 4.5 feet in height were made on individual codominant white spruce trees released on one, two, three, and four sides, and on untreated controls. Results showed that after 10 years annual circumference growth was still significantly related to the degree of release. The growth trend was established the first year but significant differences in annual growth were not evident until the third year. The growth rate reached a maximum during the ninth year. Trees with three and four sides released outgrew controls and trees with one and two sides released by a 2 to 1 ratio. Seasonal growth usually started around May 10, peaked during the second week in June, and ceased around August 20. Trees released on three or four sides appeared to start growing earlier and cease growing several days later than the other trees. The length of the growing season ranged from 100 to 115 days.

Available in PDF, EPUB and Kindle. Book excerpt: Discover new approaches to promote a viable forest industry while protecting non-timber values!Frontiers of Forest Biology: Proceedings of the 1998 Joint Meeting of the North American Forest Biology Workshop and the Western Forest Genetics Association gives you significant new insights on current initiatives in forest biology. Because the field is changing rapidly, you need to keep aware of current trends, as the emphasis in forest research shifts from productivity-based goals to sustainable development of forest resources. In this volume, you will find a comprehensive summary of the state of the art of forest science in North America. Whether your focus is on genetics or on the environmental aspects of forest science, plant physiology, or silviculture, you will find helpful chapters by practitioners as well as cutting-edge research by scientists. This integrated approach is unique in the field. Based on the 1998 Joint Meeting of the North American Forest Biology Workshop and the Western Forest Genetics Association, Frontiers of Forest Biology addresses changing priorities in forest resource management. This important book contains fascinating research studies, complete with tables and diagrams, on topics such as biodiversity research, the productivity of commercial species, conserving adaptive variation in forest ecosystems, and the effect of harvesting trees on nutrient leaching.The book maps the frontiers of this fast-changing science with chapters on: the social, biological, and industrial context of forest biology new directions for research into genetics, physiology, plant silviculture, and conservation the impact of genetics on sustainable forestry the effects of cold and disease on plant physiology regeneration of various species after logging new species adapted for agroforestry the impact and management of exotic weeds Frontiers of Forest Biology offers solid information on a broad spectrum of topics and suggests fresh avenues for your investigations in all aspects of forest biology.
