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...

The genus Anthracobia Boudier (Pezizales, Ascomycetes)

Creator:: Larsen, Harold J.
Abstract:: A taxonomic revision of the genus Anthracobia Boudier is presented. The genus and eight included taxa are described and figured. A discussion of the taxonomic criteria used to delimit the genus and the species is included, and a key to the recognized taxa is given. Four imperfect states for included...

Photoinduction of kaurene synthetase, an enzyme of the gibberellin biosynthetic pathway, during de-etiolation of pea seedlings

Creator:: Gomez-Navarrete, Gladys
Abstract:: Previous investigations have shown that the enzymes catalyzing the biosynthesis of the gibberellin-type of hormones from mevalonic acid in plants are compartmentalized in plastids. Moreover, the activity of one of the key enzymes in the biosynthetic sequence, kaurene synthetase, exhibits markedly enhanced activity when a dark-grown pea seedling undergoes de-etiolation...

Potato virus X : detection and inter-relationship with Verticillium dahliae and Colletotrichum atramentarium

Creator:: Goodell, Jody Jellison
Abstract:: Preliminary studies were run to determine the sensitivity and reliability of enzyme-linked immunosorbent assay (ELISA) for the detection of potato virus X (PVX). ELISA was found to be capable of detecting PVX in tobacco at a 1:3333 sample dilution. The reliability of ELISA for the detection of PVX in potato...

Successional changes associated with benthic assemblages in experimental streams

Creator:: Busch, David E.
Abstract:: Experimental streams constructed by the Weyerhaeuser Company, Tacoma, Washington, at Kalama Springs, Washington, were used to observe successional changes in the benthos. Community changes were observed relative to experimental manipulations of light intensity and nitrate concentration in two experiments. The development of benthic assemblages was followed for 150 days after...

Studies on the vesicular-arbuscular mycorrhizae of Easter lily in the Pacific Northwest

Creator:: Ames, Robert Norman
Abstract:: A study was conducted to characterize the vesicular-arbuscular (VA) mycorrhizal fungi of commercially grown Easter lily. Monthly field soil and root samples were collected from March through September, 1975, from five fields in the coastal area of southern Oregon and northern California. Soil sievings were inoculated onto clover, onion and...

The distribution of intertidal diatoms associated with the sediments of Yaquina Estuary, Oregon

Creator:: Amspoker, Michael C.
Abstract:: Sediment samples were collected from eight sampling sites along the Yaquina Estuary, Oregon from Yaquina Bay to Elk City near the head of the estuary. Samples were collected in November 1973, February 1974, May 1974 and August 1974 from two or three intertidal levels depending on the magnitude of the...

Phylloplane microorganisms on the leaf surfaces of bean (Phaseolus vulgaris L.), hop (Humulus lupulus L.), mint (Mentha piperita L.) and tomato (Lycopersicon esculentum Mill.)

Creator:: Sontirat, Pattana
Abstract:: Phyllopane microorganisms on the leaf surfaces of bean (Phaseolus vulgaris L. ), hop (Humulus lupulus L. 'Fuggle-H'), mint (Mentha piperita L. 'Mitcham') and tomato (Lycopersicon esculentum Mill. ) has been observed by cultural methods. A leaf impression method was used to examine both actively growing and inactive propagules present on...
