This book was released on 2017-11-19 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Geographic Variation in Red Alder Because all seedlings of some provenances were obtained from very small areas (for example, less than ha), they may represent a small portion of the gene pool at that general location. Procedures used to sample the local populations would thus tend to reduce variability within a provenance and may exaggerate differences among provenances.

Book excerpt: In March 23-25, 2005, an international symposium on red alder was held at the University of Washington Center for Urban Horticulture in Seattle, WA. The symposium was entitled S2Red alder: A State of KnowledgeS3 and brought together regional experts to critically examine the economic, ecological and social values of red alder. The primary goal of the symposium was to discuss new advances in the understanding of red alder biology and silviculture, changing market and nonmarket values, and the current regulatory climate for management of alder. This proceedings includes 14 papers based on oral presentations given at the symposium. These papers highlight some of the key findings from the history, ecology, biology, silviculture and economics sessions presented at the red alder symposium.
Download or read book Effects of Thermoperiod on the Early Growth of Red Alder from Different Elevations and Geographic Sources written by Allan Campbell and published by . This book was released on 1973 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study was designed to help elucidate what differences, if any, exist within the species Alnus rubra Bong., grown naturally at various elevations and locations throughout the Pacific Northwest and coastal Alaska. Increasing importance of the species, including both economic and silviculture values, prompted the investigation into the early growth of red alder, an area in which detailed information is lacking. Two areas of investigation that were established included, first, an elevational transect from Newport to Marys Peak in the Coast Range of Oregon and, second, a study of ten geographic sources located throughout the range of Alnus rubra. Both phases of this investigation were conducted under three growth regimes involving the use of a 16 hour photoperiod and three thermoperiods (day-night temperatures are: 21°, 16°C; 10°, 10°C and 21°, 21°C). The Transect Study showed differences between red alder conelets (weight and size) and seeds (weights and germination) from different elevations to be significant at the 1% level. The effect of the lower thermoperiod (10°, 10°C) in reducing the rate of germnination was also shown. No significant differences were found between seedlings representing the various elevations in other characteristics (height, diameter and leaf dimension). The Geographic Study, involving wildlings supplied by the U.S. Forest Service, was concerned primarily with seedling height growth and leaf size. Significant differences were found between seedlings from different geographic locations but, because of the limited number of seedlings available, the reliability of the data to accurately express variation between these locations is questionable. The effect of thermoperiod within a single tested environment was also significant but with results that were opposite to those obtained in the Transect Study. In the Geographic Study the height growth of seedlings under the cold condition (10°, 10°C) was significantly greater than for seedlings grown under the other growth conditions. In the Transect Study, the seedlings grown under the cold condition were significantly shorter than those grown under the other regimes.

Download or read book New Perspectives in Wood Anatomy written by P. Baas and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: On the occasion of the 50th Anniversary of the International Association of Wood Anatomists several symposia were held during the 13th International Botanical Congress in Sydney, August 1981. Extended versions of most of the invited papers presented there, and some additional papers on aspects which could not be included in the congress program constitute the contents of this book, which intentionally received the pretentious title 'New Perspectives in Wood Anatomy'. To some readers it may seem a paradox that under this heading papers on a diversity of partly traditional wood anatomical subjects are assembled, even including two with a historical emphasis. However, a study of the history of wood anatomy and of how students of that discipline joined forces in an inter national association, brings to light many facts and views which deserve the attention of present day and future wood scientists as a potential source of in spiration for their research and organisational work.
