Abstract:

Plant population management is an important aspect of cotton production. Recommendations for optimum plant densities range from 25,000 - 45,000 plants per acre (ppa). A study was conducted in Pinal county in 1994 to evaluate the recommendations already given. Plant densities for this study ranged from approximately 18,000 - 65,000. Yields increased with populations of 18,000, 28,000, and 39,000 ppa. For populations of 43,000 and 65,000 ppa a corresponding decrease in yield from 39,000 ppa was observed. This study serves to reconfirm the recommendations for optimum plant densities.

Abstract:

Plant fungal pathogens are a major threat to food security worldwide. The most important method of protecting plants against fungal attack is the use of fungicides, but the development of resistance towards synthetic fungicides is of great concern. Moreover, the health risks associated with the use of chemical fungicides increase the need to search for safe, efficacious and environmentally friendly fungicides. Plants produce antifungal agents by secondary metabolism to protect themselves from fungal attack, and therefore many plant species have substantial antifungal activity. The use of plant

Abstract:

Antigen expression through the Chloroplast Transformation Technology (CTT) produces bioencapsulated subunit-vaccines, capable of eliciting immune responses when delivered orally. Considerable challenges to effective plant-based vaccines are the normalization of dosage and preservation of accumulated antigen, which is complicated by variable high water content and protease activity. This study critically examines the efficacy of lyophilization in dehydrating plant-tissues and preserving plant-derived antigens with vaccine potential. Lyophilization was optimized through gravimetric analysis usin

Abstract:

Fusarium root rot is one of the most important diseases of pulse crops, with numerous Fusarium spp. comprising the disease complex. Fusarium solani and F. avenaceum have been reported to be major pathogens in the pea root rot complex, and all commonly grown varieties are susceptible. Greenhouse methods to evaluate peas for resistance to Fusarium root rot resulted in inconsistent disease severity across varieties. In 2015, F. avenaceum infested field plots were more heavily damaged based on emergence and yield than F. solani infested plots, and opposite trends were observed in 2016. Differences

This in turn heats the air in the collector, which flows radially inwards towards the chimney. This movement is driven by the difference between the hydrostatic pressure of the air inside- and outside the solar chimney

Abstract:

El rápido crecimiento de las ciudades es considerado un motor del cambio global antropogénico y se ha convertido en una problemática ambiental por los diversos impactos que genera. Considerando que la mayor parte de la población mundial vive en áreas urbanas, las ciudades pueden ser consideradas como los ecosistemas óptimos para el planteamiento y promoción de medidas de mitigación a la problemática ambiental que se acrecienta en las últimas décadas. Así han surgido prácticas alternativas enfocadas a la mitigación, reducción y prevención del impacto ambiental, entre éstas la implantación de té

Abstract:

Pedilanthus palmeri Millsp. was evaluated as a potential interior landscaping plant. The optimal propagation technique, production and post-production light requirements, growth regulator response and photoperiod requirement were analyzed. Cuttings were successfully rooted within five weeks after treatment with aqueous solutions of IBA. Root fresh weight increased from 0.58 g with 0 mg·liter⁻¹ IBA to 1.12 g with 6736 mg·liter⁻¹ IBA. No difference in leaf length, width or thickness, plant height or node number was found between plants grown under 77% and 88% shade. Plants moved to a low light i

Abstract:

Culture filtrates of 13 microbial antagonists exhibited in vitro growth inhibition of a range of test contaminations of herbaceous and woody plant tissue culture systems. Filtrates produced by Bacillus subtilis and Trichoderma viride isolates displayed the greatest broad- range inhibitory activity. Microscopic analysis of antagonized fungal mycelia revealed altered hyphal morphology. Maximum filtrate inhibitory activity was produced when selected antagonists were cultured within a pH range of 5-7 and a temperature range of 20-35°C. Filtrates were thermo-stable at 70°C and could be stored for u

Abstract:

Master of Science<br>Department of Horticulture, Forestry, and Recreation Resources<br>Cheryl Boyer<br>The nursery industry in the United States, particularly in the Great Plains region is growing; however, materials used in creation of artificial substrates used to grow ornamental nursery crops continue to increase in price. Eastern Redcedar (Juniperus virginiana L.) is an indigenous plant throughout much of the United States and, in the Great Plains, it has become a pest. Use of wood-based substrates (primarily composed of pine trees) has been proven effective in both nursery and greenhouse

Abstract:

In Sweden the industries releases about 50 TWh / year of low temperature waste heat[1], often in the form of humid air flows. Today, conventional flue gas condensation is only exploiting a minor part of the energy from these flows. It is a well-established and profitable way of improving the efficiency of district heating plants and other boilers for wet fuels. However, the condensation is only applicable when the dew point of the flue gas is above the temperature demand for the heating net. The paper industry gives a good illustration of the limitations for conventional condensation: severa
