Available in PDF, EPUB and Kindle. Book excerpt: Longleaf pine, although widely distributed in the presettlement forests of the southern Coastal Plain, now occupies less than 10 percent of its original range. It is a highly desirable species because it resists tire, insects, and disease and produces excellent quality solid-wood products. Regeneration of the species either by natural methods or by planting of bare-root nursery stock has been difticult, and renewed interest in it has resulted in evaluation of new approaches to seedling establishment. Using container stock has greatly improved the success of longleaf pine establishment. Practical guidelines are presented that will help nursery personnel consistently produce good container stock that will survive well and initiate early height growth.

Download or read book Inoculation of Container grown Plants with Vesicular arbuscular Mycorrhizae written by Brenda Joan Biermann and published by . This book was released on 1982 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies were conducted on inoculation of container-grown plants with vesicular-arbuscular (VA) mycorrhizae. Intraradical vesicles formed in colonized roots were found to serve as propagules and significantly contribute to the infectivity of these roots. A procedure was developed for separating intraradical vesicles from roots; isolated intraradical vesicles were able to colonize new host roots. Extraradical vesicles of Gigaspora margarita were not infective propagules. Treatment of mycorrhizal roots with sodium hypochlorite as a surface-sterilant reduced their infectivity. Pre-transplant inoculation of geranium with Glomus fasciculatum resulted in spread of the endophyte within the root system and greater and more uniform growth at flowering. Mycorrhizae were sufficiently established on most seedlings at a minimum of 2 weeks after emergence to persist after transplanting. Pre-transplant inoculation increased geranium growth over that of controls transplanted into heavily inoculated soil, even when growth did not differ at the time of transplanting. Soilless plant growth media such as peat, bark, perlite and vermiculite inhibited formation of VA mycorrhizae and host growth response compared to media containing soil. Peats from different sources varied in effects on mycorrhizal growth response of geranium. Utilization of rock phoshate or bonemeal instead of sodium phosphate as a fertilizer P source did not improve establishment of mycorrhizae and host growth response in various media. Addition of 5-10% Turface, bentonite, silt loam soil or clay subsoil to peat or vermiculite resulted in increased colonization of host roots and significant mycorrhizal growth response, but amendment with liquid sludge inhibited mycorrhiza formation. Differential VA mycorrhiza formation and host growth enhancement in different growth media were attributed to differences in equilibrium solution P concentration after media had been saturated with fertilizer. Growth response of geranium to inoculation with G. fasciculatum increased with increasing pre-inoculation soil heat treatment temperatures from 45°C to 120°C. Colonization of roots of geraniums inoculated with G. fasciculatum was not affected by soil treatment temperature, but treatment for 30 min at 55°C or higher eliminated colonization by indigenous mycorrhizal fungi. The shoot P concentration of inoculated plants relative to controls increased with increasing temperature of soil treatment.

Download or read book Polymer Macro and Micro Gel Beads Fundamentals and Applications written by Amos Nussinovitch and published by Springer Science & Business Media. This book was released on 2010-09-11 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beads made from Egyptian faience have been excavated from grave deposits (c. 4000–3100 BC), together with beads of glazed steatite (a soft rock) and of se- precious stones such as turquoise, carnelian, quartz, and lapis lazuli. Information on these and many more ancient beads used for ornaments and jewelry, ritual ceremonies, as art artifacts and gifts for amorous women throughout history, and descriptions of the raw materials (e. g. , glass, bone, precious and other stones) and manufacturing technologies used for their production can be located in many references. Many books are devoted to the description of beads that are not of water-soluble polymer origin, techniques for their production, their art, value, and distribution, re?ecting the wealth of information existing in this ?eld of science and art. On the other hand, there are no books fully devoted to the fascinating topic of hydrocolloid (polymeric) beads and their unique applications. A few books c- tain scattered chapters and details on such topics, while emphasizing the possibility of locating fragments of information elsewhere; however, again, there is no book that is solely devoted to hydrocolloid beads and their versatile applications. In the meantime, the use of water-soluble hydrocolloid beads is on the rise in many ?elds, making a book that covers both past and novel applications of such beads, as well as their properties and ways in which to manipulate them, crucial.

This book was released on 2012-12-06 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: The public's attitude toward air pollution in the United States evolved substantially during the 1960s. One of the results of the nation's emerging environmental ethic was the creation of the U. S. Environmental Protection Agency (EPA) in December of 1970. Prior to this time, research was focused on the impacts of air pollution on human health and welfare and was largely conducted by several federal research agencies, which included the Department of Health, Education, and Welfare; the National Oceanic and Atmospheric Administration; and the U. S. Department of Agricul ture. After the creation of the EPA, much of this work was consolidated in one regulatory agency, which resulted in periodic evaluations of the various effects of atmospheric pollution on human health, materials, agriculture, and forest ecosystems. At the same time that environmental interest was growing in the United States, concern increased in the European scientific community and public over the ecological impacts of acidic deposition. As the magnitude of the damage to European lakes and streams and the widespread decline in Norway spruce and silver fir was reported, concern that similar problems were occurring in the United States increased substantially. This concern was heightened by press reports of high elevation spruce-fir forest declines in the Adirondack and Appalachian Mountains and the decline and death of sugar maples in the northeastern United States and Canada.
