Determining The Rate Constant For Hydrogen Abstraction From Water By P-Fluorophenyl Radicals, Autumn B. Barloon

Research & Creative Achievement Day

Highly reactive oxygen species (hROS) cause oxidative stress that can lead to diseases such as cancer and cardiovascular diseases. This research explored one of the ways these species can be made in the body; through abstraction of hydrogen from water by phenyl radicals. The phenyl radicals can enter the body through medications such as benzoyl peroxide, which is commonly used to treat acne making this research of relevance in the medical community. In this research, p-fluorophenyl radicals (FPh) were generated from p-fluorophenylazoisobutyronitrile (FPAIN) by visible photolysis in the presence of varying amounts of water and 3-iodobenzotrifluoride (ArI). The …

Utilizing Macroinvertebrate Communities And Chloride Levels To Evaluate Water Quality In Three Streams Near Winona, Minnesota, Amelia Engman, Izabella Setla

Research & Creative Achievement Day

Certain water quality and chloride levels are ideal for specific macroinvertebrate species. This study evaluates the water quality of three streams in and around Winona, Minnesota, using the macroinvertebrate communities present and chloride levels as indicators. Three upstream samples were taken and thoroughly examined at three different locations: Garvin Brook, Gilmore Creek, and Pleasant Valley Creek. During the snowmelt season, four sets of upstream and one set of downstream water samples were taken from each. The samples were analyzed using a Vernier chloride ion-selective electrode. The Izaak Walton League of America's Save Our Streams invertebrate classification system was used to …

Synthesis Of Activated Carbon From Spent Coffee Beans, Alyssa Priebe, Jennifer Zemke

Research & Creative Achievement Day

Activated carbon is a material that is used in various industries. An important way that activated carbon is used, is to remove impurities and contaminants from water. Activated carbon is used to filter out odors and pollutants such as organic compounds by adsorbing and trapping these molecules within the structure of the carbon. The goal of this research is to synthesize activated carbon from spent coffee grounds. To this end, we are developing and tuning a protocol for the synthesis of activated carbon via a Microwave-Assisted Reaction System (MARS-TA). Variables investigated in this study are the amount of phosphoric acid …

Development And Evaluation Of Pennisetum Purpureum Mutants Through Irradiation With 60Co, R. S. Herrera, M. García, R. Tuero, A. M. Cruz, A. Romero, N. Fraga

IGC Proceedings (1977-2023)

The development of plant mutants is a commonly used procedure nowadays. One way of obtaining mutant plants has been seed irradiation with gamma rays. As these studies are not common in tropical pasture species (Micke et al., 1993, Herrera, 2001), the objective of this study was the development and evaluation of Pennisetum purpureum mutants through irradiation with ⁶⁰Co.

Small Leaf Mid-Rib Xylem Related To Leaf Freeze Tolerance Trait In Bahia (Paspalum Notatum Flugge) Grass Lines, J. W. Breman, A. R. Blount, T. R. Sinclair

IGC Proceedings (1977-2023)

Controlled freeze (-60^o C) trials of 31 bahiagrass selections from a breeding program for cold tolerance by Blount et al. (2001) showed diverse genotype Leaf Tissue Cold Damage (LTCD). Breman et al. (2003) defined LTCD on a rating scale (1 = no damage to 9 = 100% leaf damage). Unique midrib damage was observed as part of LTCD in bahiagrass under transpiration stress after a freeze trial. Small xylem conduit diameter and area has been strongly correlated with reduced cavitation caused by freeze thaw cycles which maintain leaf tissue in evergreen temperate woody plants; further shown in …

Assessment Of Inter-Specific Diversity Of The Hedysarum Genus In Tunisia, S. Marghali, H. Chennaoui, M. Marrakchi, N. Trifi-Farah

IGC Proceedings (1977-2023)

In Tunisia, many grassland and pasture species were menaced by genetic erosion. Thus, we were interested in the Hedysarum species which constitute a very important phytogenetic patrimony able to produce forage and restore destroyed pasture land especially in arid and semi-arid areas. In order to facilitate fodder improvement, we investigated the phenetic relationships among Hedysarum species using rDNA intergenic spacer (IGS) polymorphism.

Breeding A Psyllid-Resistant Interspecific Hybrid Leucaena For Beef Cattle Production In Northern Australia, Scott A. Dalzell, F. Lemos De Moraes, G. Solis Pasos

IGC Proceedings (1977-2023)

Production of the valuable fodder tree legume Leucaena leucocephala (leucaena) is limited to the subhumid (600-800 mm annual rainfall) areas of northern Australia by the psyllid insect pest Heteropsylla cubana. Defoliation caused by severe psyllid infestations can suppress forage yields of commercial leucaena varieties by 50-80%. Susceptibility to psyllid damage is a major impediment to grazier adoption of leucaena pastures in the more humid tropical areas of Australia. A comprehensive international agronomic evaluation of the entire Leucaena genus (Mullen et al., 2003) revealed that the artificial interspecific F₁ hybrid of L. pallida x L. leucocephala ssp. glabrata …

Physical And Quality Seed Traits Observed In New Pigeon Pea (Cajanus Cajan) Hybrids, R. Usberti, J. A. Usberti Jr., R. H. Aguiar, F. C. Simoes, F. N. Cavalcante, M. Harris, Maria T. Colozza, J. C. T. Freitas

IGC Proceedings (1977-2023)

Pigeon pea seed production may be affected by factors such as % of pure seeds, mean seed weight, incidence of pests and diseases and environmental stresses. Harvested seeds from different cultivars may also vary in germination %, hardseededness and germination speed. Hardseededness (seed coat impermeability to water) commonly occurs in forage legume species (Hopkinson, 1993). There is considerable variation among different entries for seed characters but this is not considered within genetic materials. This research analysed harvested seeds of selected individuals of two segregating F₂ pigeon pea populations for the above cited traits and assessed the range of variation …

Genetic Variability Of Yield And Its Components In Winter Forage Pea Cultivars, V. Mihailović, A. Mikić, Đ. Karagić, S. Katić, I. Pataki

IGC Proceedings (1977-2023)

The genus Pisum (peas) is rich in variability of morphological traits. It provides an excellent basis for breeding, but is also one of the reasons for the still undefined status of Pisum taxons (Mihailović et al., 2004a). The majority of forage pea cultivars used belongs to subspecies sativum and variety arvense (Maxted & Ambrose, 2000). The objective of our study was to determine genetic variability of yield and its components in six winter forage pea cultivars of different origin and to evaluate their breeding potential.
