This book was released on 1993 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plastic shelters were used to grow red oak seedlings on good-to-excellent Appalachian hardwood growing sites in north central West Virginia. Preliminary results indicate that shelters have the potential to stimulate development of red oak seedling height growth, especially if height growth continues once the seedling tops are above the 5-foot-tall shelters.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The success of northern red oak (Quercus rubra L.) in the oak-hickory forest type and its growth and development into the overstory is of great concern due to the value of this species as a source of forest products and mast for wildlife. There is a general consensus that rapid oak seedling height growth occurs above certain threshold levels of light, soil moisture, and nutrients. If these specific levels and the relative importance of competition between northern red oak (NRO) seedlings and other individual plant species can be determined, then the implementation of more precise management practices that promote rapid NRO seedling height growth and more cost-efficient competition control treatments could be developed. The detection of genetic family differences among artificially regenerated NRO seedlings could also have future applications in advancing the competitive ability of NRO in the field. This study had three objectives. The first objective was to identify light, soil moisture, and nutrient levels in the immediate vicinity of NRO seedlings that lead to rapid height growth. The second objective was to establish which plant species are the most important competitors limiting these resources and thus the height growth and survival of NRO seedlings. The third objective was to identify potential genetic family differences among the NRO seedlings used in this experiment. This study was conducted on moderately productive sites in mature oak-hickory forests on the University of Tennessee Forestry Experiment Station at Oak Ridge in east Tennessee. A randomized complete block design was used, and the dependent variables were height growth and percent survival for all NRO seedlings. Six treatments were ...

This book was released on 1993 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maintenance of oak species and a lack of oak regeneration are major silvicultural problems in many upland oak forests of the Eastern United States. Advance oak regeneration where present generally is small and lacks vigor. As a result, artificial regeneration is sometimes used, but planted oak seedlings usually do not grow well. Plastic tree shelters have been used to protect planted and natural oak seedlings from deer browsing and to promote seedling height growth and survival. This study examined the growth and survival of planted and natural red oak seedlings and seedlings from planted acorns within translucent tree shelters, fences, and unprotected controls with and without herbicide application under a shelterwood seed-cut stand. After 2 years, surviving control planted seedlings were significantly shorter than those protected by tree shelters and fences. The average height of seedlings planted within tree shelters and fences was 0.88 foot and was not significantly different. Planted control seedlings were shorter after the second year than the first, suggesting that these unprotected seedlings had been browsed by deer. The best survival of planted seedlings was inside the fences, with and without herbicide. Survival in shelters was 82 percent when herbicide was used and 40 percent without herbicide, probably due to low light intensity. Survival of planted control seedlings was unsatisfactory whether or not herbicide was applied, likely the result of browsing. Only 16 percent of the acorns planted within shelters produced seedlings and none grew outside of shelters. Small mammals destroyed most planted acorns. Natural seedlings grew little and their height inside and outside of shelters was not different from that of planted seedlings. Recommendations based on these results should improve results when tree shelters are used.

Download or read book Influence of Nursery Stock Planting Practices Fertilization and Competition Control on Initial Survival and Growth of Nuttall and White Oak Seedlings written by Joshua Larue Moree and published by . This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This project evaluates the survival and initial growth response of oak seedlings produced under special nursery protocols ("enhanced" seedlings) compared to nursery-run oak seedlings of the same species, and the influence of various cultural practices on these same nursery stocks. Survival did not differ significantly between nursery stocks. Significant differences in survival among competition control treatments did occur. Intensive competition control regimes using glyphosate can negatively impact seedling survival if seedlings come in contact with herbicide spray drift. Nursery-run seedlings had significantly greater growth and many were larger than enhanced seedlings after two growing seasons. Height growth was typically greater with seedlings receiving less intensive competition control, while groundline diameter (GLD) growth was greatest with seedlings receiving more intensive competition control. Subsoil and auger planting typically resulted in greater growth than normal hand planting. Fertilization improved growth in certain areas, but the effects diminished after the first growing season.
