The Molecular Characterization Of The Virus And Virus-Like Agents Present In Ta Tao 5 Germplasm Of Prunus Persica , Diana Marini

All Dissertations

Peach production in the southeastern United States is limited by late spring freezes. Ta Tao 5 germplasm, used either as an interstem or by chip bud inoculation, has been shown to delay bloom and avoid the effects of these late freezes. The growth modification is graft transmissible and the germplasm has been found to be infected with ACLSV, APruV-3, and PLMVd. Using a combination of PCR, cloning, and sequencing techniques, a molecular characterization of the three graft-transmissible agents present in Ta Tao 5 has been completed.

The complete nucleotide sequence of the genome of the isolate of ACLSV (ACLSV-Ta Tao …


Measuring And Modeling Species Specific, Joseph Bowden Aug 2007

Measuring And Modeling Species Specific, Joseph Bowden

All Theses

Differences in transpiration have been reported in tree species over the last several decades; however, few studies have teased out the environmental component with a common garden. Species specific transpiration was measured via sap flow on twenty trees from five deciduous hardwood species, Prunus x yedoensis Matsum., Acer rubrum L. 'Autumn Flame', Acer buergeranum Miq., Prunus serrulata Lindl. 'Kwanzan,' and Platanus x acerifolia (Ait.) Willd., throughout the 2005 growing season in a plantation. In addition, monthly growth and gas exchange measurements were collected for each species and used to parameterize a three dimensional spatially explicit transpiration model, MAESTRA. The model …


Soil Fertility Management In Organic Vegetable Production, Susannah Rauton Aug 2007

Soil Fertility Management In Organic Vegetable Production, Susannah Rauton

All Theses

Organic vegetable production is a rapidly growing sector of agriculture. Due to limitations on synthetic inputs imposed by the USDA National Organic Program (NOP), research is necessary to determine which soil amendments are viable options for organic farmers. Field trials were conducted at the Clemson University Calhoun Fields Laboratory Student Organic Farm. A variety of vegetable crops were grown, including Jericho lettuce in the springs of 2005 and 2006, yellow crookneck squash in the summers of 2005 and 2006, and Early Jersey Wakefield cabbage in the fall of 2005. Soil amendment treatments consisted of combinations of the following: poultry compost, …
