Comparative gibberellin relationships in tall and dwarf peas (Pisum sativum L.)

Creator:: Anderson, James David
Abstract:: Experiments were performed to determine whether a direct correlation exists between the growth rates of tall and dwarf peas grown either in the light or in the dark and endogenous gibberellin (GA) content. Three separate but related experimental approaches were utilized: (1) the determination of possible qualitative and /or quantitative...

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...

Morphology, ultrastructure and mating of sporidia of a wheat-bunt fungus, Tilletia caries (DC.) Tul.

Creator:: Kollmorgen, James Frederick
Abstract:: The teliospore of Tilletia caries germinates to produce a promycelium with a whorl of primary sporidia at its tip. The time between emergence of the promycelium and the development of primary sporidia averaged 2.3 h. Fusion between compatible sporidia occurred within an additional 3.8 h. Primary sporidia appeared to be...

Cap-Independent Enhancement of Translation by a Plant Potyvirus 5' Nontranslated Region

Creator:: Carrington, James C. and Freed, Deon D.
Abstract:: The RNA genome of tobacco etch virus (TEV), a plant potyvirus, functions as an mRNA for synthesis of a 346-kilodalton polyprotein that undergoes extensive proteolytic processing. The RNA lacks a normal 5' cap structure at its terminus, which suggests that the mechanism of translational initiation differs from that of a...

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...

Nursery, cold storage, and field studies on western conifers inoculated with spores of Pisolithus tinctorius

Creator:: Alvarez, Isabel Fernandez
Abstract:: Inoculations of white fir, Shasta red fir, Douglas fir and ponderosa pine with Pisolithus tinctorius spores when outplanted failed to produce P. tinctorius mycorrhizae at the end of the first growing season. In the third year a few P. tinctorius mycorrhizae were formed on white fir. Inoculations reduced seedling survival...

The genus Leucogaster (Basidiomycetes, Leucogastraceae)

Creator:: Fogel, Robert Dale
Abstract:: Three provisional species are described as new: Leucogaster couchii, L. gelatinosus, and L. microsporus. Leucophlebs candida is transferred to Leucogastef, completing the transfer of all Leucophlebs species to Leucogaster. L. columellatus is transferred to Sclerogaster. L. longisterigmatus is synonymized with L. rubescens, L. foveolatus with L. odoratus, and L. fulvimaculatus...
