Biological and molecular characterization of wild type parental and nonpathogenic mutant strains of Pseudomonas syringae pathovars phaseolicola and syringae

Creator:: Bertoni, Gregory
Abstract:: The in planta growth of three wild type strains of phytopathogenic bacteria and three nonpathogenic mutant strains was studied to determine if mutations eliminating the ability of the mutant strains to cause disease had affected their growth in leaf tissue. The mutant strains were obtained by Tn5 mutagenesis of Pseudomonas...

Yield loss assessment in nonprotected winter wheat varieties (Triticum aestivum, L. em Thell)

Creator:: Camacho Casas, Miguel Alfonso
Abstract:: The effects of some soil- and foliar-borne biotic factors on grain yield and the components of yield were evaluated using five winter wheat varieties sown at two dates. Within each planting date, varieties were grown under four different combinations of two soil treatments (fumigation and nonfumigation) and two foliar treatments...

Studies on resistance of rice to Sogatodes oryzicola (Muir) and a parasitoid, Haplogonatopus sp., in Costa Rica

Creator:: Alvarez B., Francisco
Abstract:: Twenty-one rice cultivars were evaluated to determine the difference between populations of Sogatodes oryzicola (Muir) (Homoptera: Delphacidae) in Costa Rica and Colombia, Survival, mortality and population development of S. oryzicola on five selected cultivars was used to determine levels of plant resistance. The importance and potential of the parasitoid-predator Haplogonatopus...

The effect of light and nitrogen limitation on western conifers : response to Armillaria ostoyae infection

Creator:: Entry, James A.
Abstract:: Armillaria (Fr. ex. Fr.) is a parasite whose pathogenicity and role in forest ecosystems often depends upon the physiological condition of the tree. Therefore, I tested the frequency and severity of Armillaria ostoyae (Romagn.) Herink infection among Abies grandis (Dougl.) Lindl., Larix occidentalis Nutt., Pinus contorta var. latifolia (Engelm.), Pinus...
