Ethylene production from cultures of Cylindrocladium and from Cylindrocladium-infected azalea leaves

Creator:: Axelrood, Paige Ellen
Abstract:: Ethylene was produced by Cylindrocladium floridanum and C. scoparium in culture. Production was methionine dependent and maximal during the active growth phase of the fungus, beginning shortly after spore germination. More ethylene was produced sooner by C. floridanum than C. scoparium. Ethylene was produced by Cylindrocladium both from active mycelium...

Inoculation of container-grown plants with vesicular-arbuscular mycorrhizae

Creator:: Biermann, Brenda Joan, 1954-
Abstract:: Studies were conducted on inoculation of container-grown plants with vesicular-arbuscular (VA) mycorrhizae. Intraradical vesicles formed in colonized roots were found to serve as propagules and significantly contribute to the infectivity of these roots. A procedure was developed for separating intraradical vesicles from roots; isolated intraradical vesicles were able to colonize...

The role of ethylene in ectomycorrhiza formation and Fusarium infection of Douglas fir roots

Creator:: Graham, James Herbert
Abstract:: The ectomycorrhizal fungi Cenococcum geophilum, Hebeloma crustuliniforme and Laccaria laccata produced ethylene in vitro in modified Melin-Norkrans liquid medium only if amended with 2.5 to 10 mM methionine; Pisolithus tinctorius failed to produce ethylene unless the cultures were renewed with fresh methionine-amended medium prior to ethylene assay. An additional 19...

The biology and control of Phytophthora root and stem rot of apple rootstocks from stool beds

Creator:: Tidball, Carolyn Jean
Abstract:: The present studies were conducted to better understand the etiology, epidemiology and potential control of the Phytophthora stem root rot as it occurs in apple stool beds. Symptoms of Phytophthora root and stem rot occurred as early as May and continued to develop throughout the growing season. Sunken brown-black lesions...

Relationship of extra-matrical hyphae of vesicular-arbuscular mycorrhizal fungi to plant growth response

Creator:: Kough, John Lawrence
Abstract:: The colonization of several species of plants by vesicularar-buscular mycorrhizae (VAM) was studied to determine how host, soil, or symbiont factors interacted to enhance growth of the host plant. Seedlings of two species of the Cuppressaceae and two of the Taxodiaceae formed VAM; colonization significantly improved growth. This response to...

Microbial changes and interactions in the rhizosphere of vesicular-arbuscular mycorrhizal plants

Creator:: Meyer, Julie (Julie Rae)
Abstract:: The influence of vesicular-arbuscular mycorrhizae (VAM) on populations of general taxonomic and functional groups of naturally-occurring rhizosphere bacteria and actinomycetes associated with roots of sweet corn (Zea mays var. rugosa) and subterranean clover (Trifolium subterraneum L.) was assayed using selective media. Sporangial production by Phytophthora cinnamomi was also used as...

Effects of Preinoculation with VAM fungi isolated from different sites on plant tolerance to salinity in soils amended with sodium chloride

Creator:: Cantrell, Isabella Cardona
Abstract:: The hypothesis that inoculation of transplants with vesicular-arbuscular mycorrhizal (VAM) fungi before planting into saline soils would alleviate salt effects on growth and productivity was tested on lettuce (Lactuca sativa L.) and onion (Allium cepa L.). A secondary hypothesis was that the fungi isolated from a saline soil would be...

Biology and control of Fusarium spp. on Douglas-fir (Pseudotsuga menziesii)

Creator:: Hoefnagels, Mariëlle Henriette, 1965-
Abstract:: Fusarium spp. are among the most important pathogens of Douglas-fir (Pseudotsuga menziesii) seedlings in bareroot nurseries. Currently the most effective disease control method is soil fumigation with methyl bromide. As methyl bromide is phased out, however, other disease management strategies may become more important. We explored two alternative approaches to...
