Soil solarization effects on plant growth variables of field-grown tree saplings

Creator:

Fraher, Simon

Abstract:

Soil solarization has been used throughout the world, but its effect on plant growth variables in ornamental tree saplings in the Willamette Valley are not well documented. Solarization could be an alternative to chemical controls for soil pathogens and weeds, and it may also influence plant growth factors. This study...

Soil solarization at an organic farm: effects on weed emergence, soil nutrients and soil microbial communities

Creator:

Trammell, Caleb, Eberhart, Joyce, and Parke, Jennifer L.

Abstract:

Weed management is one of the main challenges for organic agriculture. Soil solarization has been shown to be an effective mitigation strategy for weeds and soil borne plant pathogens but few studies have been conducted in cooler climates such as the Pacific Northwest.

Soil solarization effects on plant growth variables of field-grown tree saplings

Creator:

Fraher, Simon

Abstract:

Solarization could be an alternative to chemical controls for soil pathogens and weeds, and it may also influence plant growth factors. Biomass, shoot length, and AMF colonization were examined in red oak (Quercus rubra), Mazzard cherry (Prunus avium), and hawthorn (Crataegus monogyna) at J. Frank Schmidt & Son Co. nursery...

Relative heat sensitivities and the potential for soil solarization to remediate nursery beds infested with Phytophthora spp.

Creator:

Weidman, Clara Suzanne

Abstract:

Infestations of container nursery beds by Phytophthora spp. can be persistent and costly. One method of disinfestation that does not require the use of chemicals is soil solarization, which captures energy from the sun to heat soil and thermally inactivate target pathogens. In laboratory temperature gradient experiments, I investigated the...

Undergraduate Thesis
Soil quality assessment of Willamette Valley soils and root colonization potential by arbuscular mycorrhizal fungi

Creator:

Allen, Natalie M.

Abstract:

Interest in measuring soil quality continues to increase worldwide in view of demands on land productivity and the necessity to preserve soil resources, yet identification of suitable indicators for soil quality assessment is still evolving. This study adapted 10 biological, physical, and chemical indicators of soil quality identified by the...

Masters Thesis
The effects of Phytophthora ramorum stem inoculation on aspects of tanoak physiology and xylem function in saplings and seedlings

Creator:

Stamm, Elizabeth A.

Abstract:

Phytophthora ramorum, an oomycete plant pathogen, is the causal agent of sudden oak death, a serious disease of Fagaceous trees in California and Oregon over the last decade. Tanoak (Notholithocarpus densiflorus) is one of the most susceptible host species, but the cause of host mortality is poorly understood. Previous research...

Masters Thesis
The effects of Phytophthora ramorum infection on hydraulic conductivity and tylosis formation in tanoak sapwood

Creator:

Collins, Bradley R.

Abstract:

Tanoak (Lithocarpus densiflorus), along with some other members of Fagaceae, are susceptible to sudden oak death caused by the oomycete Phytophthora ramorum. Symptoms of the disease include dying crowns, bleeding cankers, and eventually death of infected trees. The cause of mortality is not well understood, but recent research indicates that...
