Studies on the etiology and epidemiology of bull's eye rot of pears

Creator:: Henriquez, Jose Luis, 1961-
Abstract:: The objective of this dissertation is to introduce low-cost processing methods for the fabrication of ZnO transparent thin-film transistors (TTFTs). A novel method for depositing ZnO body layers via spin-coating of a zinc nitrate-based spin solution is presented. The processing conditions of spin-coated ZnO are optimized to produce continuous and...

Plant hormone-induced defense responses against Botrytis cinerea

Creator:: Akagi, Aya
Abstract:: Several plant hormones, including ethylene and jasmonates, are known to mediate responses against biotic and abiotic stress. The first and second objectives of this thesis were (i) to elucidate the role of ethylene in defense responses against Botrytis cinerea and specifically (ii) to determine the potential contribution of ethylene response...

Factors affecting development of iris rhizome rot caused by Botrytis convoluta Whetzel and Drayton

Creator:: Maas, J. L.
Abstract:: Abundant conidial and sclerotial production occurs on iris plants infected with Botrytis convoluta Whetzel and Drayton during the cool moist months of the year. Experiments were designed to study the survival and inoculum potential of conidia and sclerotia. Basic nutritional requirements of the fungus in culture were also studied. Results...

Biology, epidemiology, and biological and chemical control of Phytophthora vignae

Creator:: Fernando, W. Gerard Dilantha
Abstract:: Phytophthora vignae, causal agent of stem and root rot of cowpea (Vigna unguiculata), was reported for the first time in Sri Lanka. The pathogen was found in cowpea field soils from 3 of 5 geographic regions sampled. Only one site however, had plants exhibiting disease symptoms. Of the eight cowpea...

Breeding for bruchid resistance in common bean (Phaseolus vulgaris L.) : interspecific introgression of lectin-like seed proteins from tepary bean (P. acutifolius A. Gray), genetic control and bruchid resistance characterization.

Creator:: Kusolwa, Paul Mbogo
Abstract:: Interspecific hybridization was initiated between wild P. acutifolius accession G40199 and P. vulgaris to introgress resistance to Acanthoscelides obtectus (bean seed weevil). F1 interspecific hybrids were recovered by embryo rescue and maintained until flowering. Mostly sterile hybrids were backcrossed twice to common bean cultivar ICA Pijao to recover sufficient fertility...

Basic and applied studies on Douglas-fir beetle : spatial relationships of infestations, lipids and host habitat, and attraction distances of pheromone-baited traps

Creator:: Dodds, Kevin J.
Abstract:: Three studies on Douglas-fir beetle (DFB), Dendroctonuspseudotsuae, were conducted to investigate its basic and applied biology. Studies included investigations into the spatial relationship of DFB infestations over multiple years and multiple landscapes, relationships between DFB brood adult lipid levels and position of development along the length of tree boles, and...
