Cadmium Accumulation And Distribution In Lettuce And Barley, Fardausi Akhter
Cadmium Accumulation And Distribution In Lettuce And Barley, Fardausi Akhter
Electronic Thesis and Dissertation Repository
Cadmium (Cd) is a non-essential trace element and its environmental concentrations are increasing due to human activities. Edible plants can accumulate high concentrations of Cd, which could be toxic to humans. Understanding how and where Cd is stored in plants is important for ensuring lower concentration of Cd in the food. In this thesis, the accumulation and distribution of Cd in three agricultural plants, namely lettuce (Lactuca sativa L.), barley (Hordeum vulgare L.) and radish (Raphanus sativus L.), were investigated with a focus on the potential mechanisms involved in the localization of Cd in the root. The …
Hairy Roots As A Model To Investigate The Role Of Suberin In The Phytophthora Sojae-Soybean Pathosystem, Pooja Sharma
Hairy Roots As A Model To Investigate The Role Of Suberin In The Phytophthora Sojae-Soybean Pathosystem, Pooja Sharma
Electronic Thesis and Dissertation Repository
Part of the resistance mechanism of soybean (Glycine max [L.] Merr.) to Phytopthora sojae Kauf. & Gerd. involves pre-formed root suberin. In order to investigate the role of suberin in this host-pathogen interaction, I characterized hairy roots, formed as a result of Agrobacterium rhizogenes (Riker et al.) Conn infection, as a model to be used as a reliable soybean transformation system. I established hairy root cultures and demonstrated that they were a result of A. rhizogenes infection. The anatomy and suberin deposition in soybean hairy roots was examined, and found to be very similar to that of wild-type roots. …
The Effect Of Chlorine And Ozone In Controlling Microbes On Organically Grown Cilantro And Carrots, Adam Holtz
The Effect Of Chlorine And Ozone In Controlling Microbes On Organically Grown Cilantro And Carrots, Adam Holtz
BioResource and Agricultural Engineering
This senior project investigates the relative efficacy of ozonated water and chlorinated water for the purpose of sanitizing freshly-harvested organic produce. The aim of this study was to assist the Cal Poly Organic Farm in deciding whether or not to invest in an ozone generator. The crops used for testing were grown organically in the same field. Carrots and cilantro were harvested and promptly treated with 5 ppm ozone solution or 25 ppm sodium hypochlorite solution. Carrots were sampled at 0, 7, and 14 days storage to determine microbial populations. Cilantro was similarly tested at 0, 6, and 12 days …
Potential For Barn Owl As Rodent Biological Control In Central California Vineyards, Hannah Tillmann
Potential For Barn Owl As Rodent Biological Control In Central California Vineyards, Hannah Tillmann
Biological Sciences
The pocket gopher (Thomomys bottae) and voles (Microtus spp.) cause significant economic damage to vineyards. In response, many growers have taken steps to attract Barn Owls (Tyto alba) to their properties to help keep these rodent populations in check. This research project investigated Barn Owl consumption of pocket gophers and voles in Central California vineyards in order to assess the efficiency of this integrated pest management strategy. I collected a total of 715 owl pellets from five vineyard locations in Templeton and Paso Robles, California over an eight-month period during nesting and post-fledging seasons. I …
Agriculture In New York State : Farm Size And Its Implications To Farmland Protection And Biodiversity Conservation, Julianna Marie Potter
Agriculture In New York State : Farm Size And Its Implications To Farmland Protection And Biodiversity Conservation, Julianna Marie Potter
Legacy Theses & Dissertations (2009 - 2024)
In the United States there are 939 million acres of land held by ranchers and farmers. Conservation of this agricultural landscape is critical to the protection of biodiversity. Management of agricultural land is also associated with the success of biodiversity protection efforts in protected areas, including parks and preserves, as well as outside protected areas. Sustained viability of the New York farming sector will enhance and secure biodiversity on farmland, as viable farms will remain part of the landscape.
