Effects Of Pasteurization (Heating) On Milled Flaxseed Quality, Cody Troy Turner Jan 2013

Effects Of Pasteurization (Heating) On Milled Flaxseed Quality, Cody Troy Turner

Cereal Science

Current food industry practices include the use of pasteurization (heat treatment) as a means to reduce the microbial counts of flaxseed (Linum usitatissimum). Flaxseed was pasteurized using a dry air heat treatment of 148 °C for 16.25 minutes and the oxidative stability was observed over a 20 week storage period. Flaxseed quality was measured using peroxide value, percent free fatty acid (as oleic), and propanal content. Peroxide values of the pasteurized milled flaxseed were found to significantly increase (P ≤ 0.05) by week 2. Propanal formation coincided with peroxide value development over 20 weeks of storage. Pasteurized flaxseed milled under …

The Wheat-Hessian Fly Interaction: Co-Evolution And Ecology In An Economically Important Plant-Insect System, Kirk Mitchel Anderson Jan 2013

The Wheat-Hessian Fly Interaction: Co-Evolution And Ecology In An Economically Important Plant-Insect System, Kirk Mitchel Anderson

Entomology

The study of wheat’s H-gene mediated resistance to Hessian flies examined the cost of the constitutively expressed H-gene which functions in the plant’s surveillance system and the cost of the downstream induced response. For the constitutively-expressed H-gene, some measures indicated costs, but a greater number indicated benefits. For the induced resistance, plants showed benefits of being attacked. It is expected that fitness costs play a role in determining the rate at which plant defense evolves, and it is important for agriculture as plant breeders decide whether to pyramid resistance genes into a single cultivar to prevent the evolution of pest …

Interactions Between Ultraviolet Light And Soybean Aphid, Aphis Glycines Matsumura (Hemiptera: Aphididae), Steven Curtis Burdick

Environmental and Conservation Sciences

Global increases in ultraviolet (UV) radiation have led to greater interest in its current and potential effects on organisms, including insects and plants. Here we report the short-term effects of UV on soybean aphids (Aphis glycines Matsumura), a common phytophagous pest of soybeans. We examined how modified amounts of UV radiation affect soybean aphids by focusing on changes in 1) soybean aphid densities and 2) within plant distribution. In a laboratory experiment artificially adding UV decreased soybean densities compared to a low UV control. In a field experiment blocking UV had minimal effects on soybean aphid densities. Further observations suggest …

An Assessment Of Integrated Weed Management Strategies For Purple Threeawn-Dominated Rangelands, Nickolas Alois Dufek Jan 2013

An Assessment Of Integrated Weed Management Strategies For Purple Threeawn-Dominated Rangelands, Nickolas Alois Dufek

Range Science

Purple threeawn (Aristida purpurea Nutt.) is a native bunch grass that is avoided by grazers. It is capable of dominating old cropland and overgrazed pastures, limiting livestock carrying capacity, and degrading wildlife habitat. Traditional management tools have had little impact on threeawn dominance in semiarid regions of the west. Our objectives were to: 1) assess fire and nitrogen treatment effects on threeawn forage quality at various phenological stages to test their potential as pretreatments in a grazing strategy and 2) examine a threeawn-dominated plant community’s response to prescribed fire, nitrogen addition, and clipping. Fire improved threeawn forage quality with greater …
