Download or read book Conifer Seedling Mineral Nutrition written by R. van den Driessche and published by CRC Press. This book was released on 1990-12-13 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conifer Seedling Mineral Nutrition provides a comprehensive review of conifer seedling mineral nutrition and its significance to forestry. The book covers relationships between mineral supply and uptake; the effects of nutrition on seedling growth; an integration of the ideas of T. Ingestad with classical growth analysis concepts; practical aspects of assessing nutrient status and details of fertilizing bare root and container nursery stock; and fertilizing vegetative propagules. The book also describes and illustrates Mycorrhizas, assessing their importance to plantation establishment in an analysis of recent papers reporting field trials. The effects of nutrients on stress resistance and establishment when applied in the nursery and while planting are discussed in the final chapter. It will prove useful to reforestation research workers, nurserymen, and silviculturalists and should be considered essential reading for forestry students.

Download or read book Conifer Cold Hardiness written by F.J. Bigras and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 593 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conifer Cold Hardiness provides an up-to-date synthesis by leading scientists in the study of the major physiological and environmental factors regulating cold hardiness of conifer tree species. This state-of-the-art reference comprehensively explains current understanding of conifer cold hardiness ranging from the gene to the globe and from the highly applied to the very basic. Topics addressed encompass cold hardiness from the perspectives of ecology, ecophysiology, acclimation and deacclimation, seedling production and reforestation, the impacts of biotic and abiotic factors, and methods for studying and analyzing cold hardiness. The content is relevant to geneticists, ecologists, stress physiologists, environmental and global change scientists, pathologists, advanced nursery and silvicultural practitioners, and graduate students involved in plant biology, plant physiology, horticulture and forestry with an interest in cold hardiness.
Download or read book Regenerating British Columbia s Forests written by R. Parish and published by UBC Press. This book was released on 2011-11-01 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: Regenerating British Columbia's Forests will assist those responsible for planning reforestation projects to reach informed decisions and will challenge them to consider primarily the biological factors basic to reforestation success rather than short-term costs and production technology. Although its main audience is practising foresters and forestry students of British Columbia, the text will be of considerable interest to foresters in other parts of Canada, the United States, and Europe who manage reforestation.
Download or read book Growth and Nutrient Allocation of Douglas fir Seedlings written by and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Regeneration of Douglas-fir following harvesting has proven difficult on many sites in British Columbia. As a result, alternative nursery practices are being explored to improve seedling growth. Using two experiments I aimed to identify an improved nutritional program for Douglas-fir seedlings. The objective of the first experiment was to identify the optimum nitrogen (N) source ratio for Douglas-fir between two inorganic sources of N, ammonium (NH4+) and nitrate (NO3- ). Seedlings were grown in controlled environments in aeroponic culture with solutions containing 0:100, 20:80, 40:60, 60:40, 80:20 or 100:0 NH4+:NO3- ratios. Growth and nutrient allocation was observed for 45 days. Different NH4+ and NO3-ratios resulted in significant differences in growth and nutrient allocation. Seedlings grown in solutions containing abundant and relatively equal portions of NH4+ and NO3- were characterized by the greatest relative growth rates, greatest biomass and stable internal nitrogen concentrations. Seedlings grown in solutions containing high NH4+ (80:20 and 100:0 NHS+:NO3- ) concentrations were characterized by lower relative growth rates, less biomass, lower internal nutrient concentrations and lower rates of photosynthesis and root respiration compared to seedlings with less NH4+ (20:80, 40:60 and 60:40 NH4+:NO3- ). Seedlings appeared to take up a greater proportion of NH4+ than NO3- from solution. The objective of the second experiment was to examine the implications of two nursery fertilization regimes for growth and nutrient dynamics. Seedlings were grown in a nursery with nutrients added at a constant rate (conventional fertilization) or at an exponentially increasing rate of 2% day-1 (exponential nutrient loading). At the time of planting, half of the conventionally fertilized seedlings were planted with slow release fertilizer packets. Growth and nutrient allocation was observed for two years following planting. In the field experiment, although exponential nutrient.
