Mycorrhizal and other root endophytic fungi of lupines in the Pacific Northwest

Creator:: O'Dell, Thomas E.
Abstract:: We investigated the root endophytic fungi of lupine using four approaches: (1) occurrence of fungal colonization in field-collected roots; (2) growth response of L. latifolius to inoculation with two types of fungi; (3) structure of root colonizations of Pinus and Lupinus by Phialocephala fortinii, a septate endophytic fungus of lupine;...

Biosystematic studies of the Mimulus moschatus complex in the Pacific Northwest

Creator:: Meinke, Robert James
Abstract:: Populations of an unknown species of Mimulus, herein described as Mimulus hymenophyllus Meinke, were located and studied near Horse Creek, a tributary of the Snake River in eastern Wallowa County, Oregon. The new species is differentiated from its apparent closest relative, Mimulus jungermannioides Suksd., by an annual habit, long petioles,...

Description of the plant communities and succession of the Oregon coast grasslands

Creator:: Ripley, James Douglas
Abstract:: In an effort to describe the plant communities and succession of the Oregon coastal grasslands, vegetation and environmental data were collected from 75 stands at 24 separate locations ranging from Cape Falcon in Tillamook County to Cape Ferrelo in Curry County. The vegetation data consisted of cover and frequency values...

The effects of a mutation within vitamin E biosynthesis upon the development and function of the photosynthetic apparatus

Creator:: Sicher, Richard Charles
Abstract:: A new photosystem-II mutant of the green alga Scenedesmus obliquus D₃, strain PS-28, has been shown to lack a-tocopherol (vitamin E). The photosynthetic activity of dark grown samples of PS-28 is about 20% of the wild-type control. Culturing the mutant at low light intentisites (10⁴ ergs/sec-cm ²) stimulates photosynthetic activity...

The mycorrhizal associations of western hemlock

Creator:: Kropp, Bradley Ray
Abstract:: Two objectives of this research were to identify fungi which are mycorrhizal with western hemlock and to examine the ecology of hemlock mycorrhizal fungi indigenous to outplanting sites. Another objective was to evaluate the effectiveness of mycorrhizal inoculation in improving the performance of outplanted hemlock seedlings. A list of over...

Factors affecting germination of endomycorrhizal spores

Creator:: Daniels, Barbara Ann
Abstract:: Four isolates of Glomus mosseae, collected from diverse geographic locations, were pot cultured on varied host plants or stored in the same soil as collected. Spores of three isolates failed to germinate on any of five agar media while the fourth germinated well on all media. Lack of germination on...

Soil fungal hyphal dynamics and seasonal hypogeous sporocarp production in western Oregon Douglas-fir forests

Creator:: Hunt, Gary, 1945-
Abstract:: Total length and biomass of fungal mycelium in the soil of a young Douglas-fir stand in the central Oregon Coast Range were estimated over 27 months with the agar-film technique. In a second study, phenology and taxonomy of hypogeous (belowground) sporocarps were studied over 32 months in a nearby, young...
